Protecting Sylvester, Toto, Dolly, Polly

Several fruits, vegetables, nuts, seeds, condiments, additives, and drugs are toxic to domestic pets.

Some harm only dogs, others only cats, and several are poisonous to both.

Livestock, rodents, lizards, fish, and birds are not immune to the negative effects of certain foods either.

Following is a list of potentially problematic foods that should be kept in a safe place where a curious, inquisitive pet cannot access them and harm itself.

Prevention is key in protecting the health of the animals you love and care about.



Apple seeds contain cyanide compounds capable of poisoning a pet dog or cat if swallowed or chewed. Cyanide prevents blood from delivering oxygen to bodily tissues, causing suffocation.

Indicators of problems in a pet suspected of eating cyanide-harboring pits, stems or leaves include the development of bright red mucous membranes, enlarged pupils, respiratory distress, fear or nervousness, and signs of shock. The condition can be fatal if untreated.


Apricot pits and the stems and leaves of its fruit-producing tree contain the poison cyanide, a potentially fatal toxin to dogs and cats.

Symptoms are the same as that for apple seed ingestion (see above). Swallowed whole, pits can also result in a bowel obstruction or blockage, possibly requiring corrective surgery.


Persin, a potentially toxic substance with a fatty acid type structure, is present not just in the avocado pit and surrounding fruit, but in the plant leaves and bark as well.

Although harmless to humans unless someone has a persin allergy and, in fact, thought to be beneficial to women suffering from breast cancer, persin (and therefore avocados) can be fatal when ingested by domestic pets.

Dogs and cats may be lucky and not have any negative symptoms if given the green fruit; others may vomit, develop diarrhea, or a combination of both. However, for some, reactions are much more severe.

Along with other pets, such as rabbits, goats, cattle, sheep, horses, birds and fish, certain dogs and cats experience heart problems, respiratory complications, and ultimately death after ingesting persin-containing foods. Symptoms of severe reactions including labored breathing, swelling of the abdomen, and fluid build-up in the chest, abdomen, or area surrounding the heart.

In addition to these problems, damage to the mammary gland has also been seen in highly sensitive animals, including in the mouse when it is fed dried avocado leaves (4, 5). Caution should be exercised even by the few with silkworms as pets; avocado plant parts are toxic to these unsuspecting leaf munchers.


The cherry pit, like that of the apricot, peach, pear, and plum, contains a form of cyanide.

Swallowed whole, intestinal problems may result; swallowed and partially to fully chewed pits can fatally poison dogs and cats.


Oranges, lemons, and limes lead to vomiting and diarrhea in dogs. Eating grapefruit has the same laxative effect, but is accompanied by the symptoms of light sensitivity and depression.

Cats have identical negative effects upon ingesting grapefruit.

Bearded dragons benefit from occasional citrus fruit consumption; over-consumption results in nutrient imbalances and possible diarrhea.


Cats fed currants can experience kidney damage due to some unknown, yet potent, toxin contained in the berry.


Responsible for the deaths of several dogs, grapes and/or raisins in as little as 9 ounce quantities have proven lethal. Slightly more fortunate animals may experience kidney damage, requiring emergency medical care, but ultimately surviving.

A few very lucky dogs may have no symptoms at all, but since the reason why grapes in their various forms (fresh, dried, fermented) are fatal to some is yet unknown, caution must be taken even if an animal has eaten grapes in the past without incident. This is because toxins may be capable of building up over time and reaching dangerous levels only gradually; a small grape-containing snack here and there may not be problematic on its own, but in combination may prove lethal.

If dogs eat a large amounts of grapes or raisins, it is recommended that they are induced to vomit, have their stomachs pumped, and are given activated charcoal and IV fluids.

Like dogs, cats can be asymptomatic or else can experience serious kidney damage if fed raisins or grapes.

Mistletoe Berries

Mistletoe berries are highly toxic to pets; one or two could prove fatal to your dog or cat.


The pit of the peach contains cyanide, which is poisonous to dogs and cats.

Symptoms of poisoning are the same as those after eating apple seeds (see above).

Peach pits may be doubly problematic and create an intestinal blockage if eaten or swallowed.


The seeds of this fruit are dangerous to dogs and cats and may result in an inflamed small intestine or an intestinal blockage.


Plum pits are cyanide-containing, as well as potential hazard if they become lodged in the intestines of dogs or cats.

Symptoms of poisoning are the same as those after eating apple seeds (see above).


Oxalates present in the leaves of the rhubarb plants have negative effects on the nervous, digestive, and urinary systems of dogs and cats.



Death by broccoli has been seen in different livestock breeds if it comprises more than 25% of the diet; gastrointestinal complications occur when it comprises more than 10%.

The problematic substance in broccoli, isothiocyanate, is considred a strong irritant of the digestive system.


Chives contain disulfides, as do garlic and onions, damaging the red blood cells of cats and dogs. However, onions are more problematic, as they have a much higher disulfide concentration, followed by garlic, and lastly, chives.


The sulfoxides and disulfides contained in garlic, whether fresh, cooked, or powdered can harm red blood cells and cause anemia in both dogs and cats.

Signs of anemia include light-colored gums and lethargy.


Mushrooms come in many varieties; some are highly toxic, while others are harmless.

Unless an owner is a mushroom expert and can tell the difference, a dog that has been suspected of eating mushrooms should be watched closely. (Mushrooms that sprout in backyards are usually toxic).

To be safe, it is recommended that the dog is induced to vomit and given activated charcoal if the mushroom is not expelled in its entirety. The wrong mushroom types can cause jaundice and liver damage, leading to internal bleeding or seizures, or can have hallucinogenic effects resulting in tremors, seizures, and coma.

If a dog vomits on its own or develops diarrhea but lacks other symptoms, likely no serious harm has been done; however, if gastrointestinal upset is accompanied by excess saliva or tears, reduced pupil size, slowed heartbeat, depressed activity or lethargy, restlessness, staggering, or a comatose and unresponsive pet, medical care is mandatory.

Although cats are less likely to eat mushrooms, they have been shown to be attracted to two poisonous varieties that can kill: the Amanita muscaria and the Amanita pantherina. In contrast, dogs are attracted to seven poisonous varieties. One, the Scleroderma species, is also fatal to pigs.


Although believed to be safe in small amounts, onions in quantities of a cup or more cause hemolytic anemia in dogs. This is because the disulphides contained in onion damage red blood cells. All forms of onion are dangerous, whether fresh, cooked, or dehydrated.

Cats are more sensitive than dogs to onions and can likely tolerate less.

Signs of problems include pale, light-colored gums and lethargy. Corticosteroids or immunosuppressants may help an animal suffering from onion-induced anemia.


Raw potatoes are laced with glycoalkanoid solamine, a substance that is poisonous to cats.

Cooked tubers give no ill effects, but raw potatoes and the stems and leaves of its plant can cause gastrointestinal irritation, bloody stools, lethargy, shaking, paralysis, and heart attack.


Tomatoes, as well as the stems and leaves, are poisonous to cats. A single small tomato is enough to cause serious gastric and intestinal reactions.



The gastrointestinal system of a dog or cat often finds almonds difficult to digest, which can lead to vomiting and other symptoms of irritation.

Salted nuts can lead to ion imbalances if eaten in high enough quantities, and may even pose a choking hazard if not chewed before swallowed.


Half of all dogs find a chocolate dose of 100mg/kg of body weight lethal.

However, lower amounts (as low as 10% of this lethal dose) can cause various levels of poisoning with symptoms such as excited behavior, twitching, frequent urination, and an elevated pulse. In some of these cases, resulting heart problems may prove fatal.

The problematic substance in chocolate is theobromine, which is lowest in milk chocolate, higher in semi-sweet varieties, and highest in bitter or baking chocolates. White chocolate has only trace amounts of theobromine and therefore is not considered a potential poison.

However, although white and milk chocolates are the least problematic as far as causing theobromine toxicity, they contain the highest amounts of fat and can cause pancreatitis or enteritis if consumed in large amounts or on a frequent basis. These conditions are life-threatening if untreated.

Cats, like dogs, are also unable to properly process theobromine and can experience seizures, coma, and death after consumption of chocolate.

Chocolate is not just toxic to dogs and cats, but to ferrets as well.


Because coffee contains the stimulant caffeine, animals ingesting it may experience overexcited nervous systems.

The lethal amount of caffeine for both dogs and cats is 150 mg/kg body weight.

Dogs may react after coffee consumption with increases in breathing and heart rate, shaking, and muscle twitching. Cats consuming caffeine often experience diarrhea and vomiting, a fast heartbeat, and shake uncontrollably, seize and collapse.

A symptomatic animal should be induced to vomit and receive activated charcoal.

Hickory Nuts

Hickory nuts cause stomach irritation and can possibly lead to an intestinal obstruction in dogs. When moldy, resulting toxins can cause serious neurological problems such as seizures.

These nuts contain the organic substance juglone which can bring about laminitis (inflammation of the hooves) if eaten by a horse. This substance has no effect on dogs.

Macadamia nuts

Containing more monounsaturated fats than any other seed, macadamia nuts are hard for dogs and cats to digest and can result in problems with the gastrointestinal tract, and in time, lead to pancreatitis.

A certain as yet unidentified component in the macadamia nut causes dogs additional complications as well.

As early as 3 to 6 hours after devouring macadamia nuts, this substance brings about drowsiness and a spike in temperature to accompany stomach upset. Neurological symptoms usually appear within 12 hours, and dogs will show difficulty moving their hind limbs or standing. Most pets recover fully on their own within 24 hours of exposure, but for dogs that recently consumed large quantities of the nut, especially nuts dipped in chocolate, inducing vomiting to limit adverse reactions is recommended.

Cats are also poisoned by this unidentified component in macadamia nuts and have digestive, muscular, and nervous system complications upon eating them.

Mustard seeds

The mustard plant and seed is toxic to chickens, cows, sheep, and horses.

After eating mustard plant parts, susceptible animals may develop oral irritation, sensitivity to light, labored breathing, and gastrointestinal upset. Problems become more severe depending on the quantity ingested. No antidote exists, so animals displaying symptoms should be given medical treatment.


Dogs given pecans as a snack can end up with gastrointestinal upset or an obstruction. When moldy, pecans cause various neurological symptoms.

This is a juglone toxin containing nut, and is therefore linked to laminitis in horses.


High in fat, these nuts can cause stomach upset and eventually lead to pancreatitis in dogs and cats.


Black walnuts and English walnuts can lead to gastrointestinal problems or a possible intestinal obstruction in dogs; moldy black, English, or Japanese walnuts have strong mycotoxins that cause seizures or other neurological abnormalities.

In horses black walnuts can cause the vascular disease laminitis. This is due to the toxin they contain known as juglone, which is not problematic to dogs.



Although not poisonous, a snack of bones is not without potential hazards.

Bones can adhere to the mouth, the throat, or intestines and can splinter and create internal damage or blockages in dogs and cats.


A high-fat diet is difficult for the cat or dog system to process and can lead to both obesity and pancreatitis.


Large amounts of liver in a dog or cat’s diet can create toxic levels of vitamin A. This has a negative effect on bones and may cause deformities, growths, or osteoporosis in cats.

In dogs symptoms of toxicity include a calcified skeleton and diseased skin.

In some cases, toxic vitamin A levels are fatal.

Lunch meats

High in both fat and salt, a diet rich in lunch meats can lead to pancreatitis in a dog or cat (25). The high nitrate content in deli meats is also unhealthy.

Milk and Dairy

Certain dogs and cats, usually older animals, are unable to process milk products and develop diarrhea after their consumption.


If fed any type of fish in large enough quantities dogs develop a deficiency in thiamine. Thiamine deficiencies cause anorexia, seizures, and death.

Believe it or not, feeding large amounts of canned tuna to a cat can have undesirable effects as well. This is because it creates an imbalance of nutrients and may also lead to a thiamine deficiency or mercury poisoning.

Raw eggs

Eating uncooked eggs can result in unhealthy skin and coats due to the avidin enzyme.

This enzyme inhibits the proper absorption of biotin in dogs and cats. In addition to avidin-related problems, eggs may be contaminated with bacteria and lead to food poisoning.

Raw fish

Raw, uncooked salmon can be infested with flukes that carry rickettsial organisms.

These organisms are released in a dog’s intestines and cause fevers within 24 hours, combined with a lack of energy and reduced appetite. Four days after consumption vomiting occurs, followed by bloody, loose stool.

Fatality rates are as high as ninety percent; hydrating treatments and antibiotics are necessary for survival in most affected pets.

Raw fish, similarly to canned tuna, if fed in too high amounts to a cat cause a thiamine deficiency. Cats are not susceptible to rickettsial infection via salmon consumption.

Undercooked meat

Improperly cooked meat of all kinds may be contaminated with bacteria, leading to gastrointestinal upset in dogs and cats.



Excessive nutmeg consumption can create serious problems for dogs resulting in seizures, tremors, or death.


Large quantities of salt dehydrate a pet cat or dog and lead to a sodium ion imbalance.

If an animal develops extreme thirst, vomits, or becomes lethargic following substantial salt consumption it may indicate kidney damage. Left untreated a pet can develop seizures or fall into a coma and die.

To avoid these complications, pets should receive IV fluid treatment.


Large amounts of sugar result in overweight pets (cats and dogs) with poor dental health and an increased risk of developing diabetes mellitus.

Sugarless xylitol candy

Sugar-free candy containing xylitol is considered dangerous to a pet’s health according to the National Animal Poison Control Center.

Not just present in candy, xylitol is found in sugarless chewy vitamins, baked goods, and gums as well. One or two sticks of gum can kill a small dog; three or more sticks can kill a 65-pound pet.

Cats are similarly susceptible to xylitol toxicity.

Xylitol causes peaks in insulin and dips in blood sugar, creating a lethargic dog or cat that is unable to retain its balance. If untreated, brain damage, liver failure, or blood disorders develop and can lead to coma, seizures, and death.

Yeast dough

The alcohol present in yeast is absorbed into the bloodstream, resulting in alcohol poisoning.

Signs a cat or dog has been poisoned include panting, vomiting, and drooling, followed by coma and eventually death. A pet may be saved from the full effects of this by being induced to vomit and receiving activated charcoal and IV fluids.

In addition to alcohol poisoning, the dough also causes problems when it expands and creates gases within the warm, moist environment of the body. This leads to gastric or intestinal rupture in dogs or cats.


Alcohol (hops)

When a dog or cat drinks alcohol it can become intoxicated. It takes only two teaspoons of whisky for a 5-pound cat to fall into a coma, and three teaspoons results in death.

Hops leads to panting, an elevated heart rate, increases in temperature, seizures, and death in dogs. It is also unsafe for cats.


Marijuana slows down the nervous system of dogs and cats, alters the heartbeat, and induces vomiting.


The nicotine in tobacco disrupts the proper functioning of the digestive and nervous systems. An elevated heart rate, coma, and death can result from nicotine poisoning in cats and dogs.

Lillie on May 05, 2020:

thanks for helping me with my presentation!!! I love you.

Shannon on December 22, 2016:

I read this article and had no idea about the toxicity of apples. I had been feeding my dog the apple cores cut from my kids lunch. It is not every day but about 3 times a week. Could I be poisoning my dog over time? He has vomited 4-5 times today. He last ate this morning but throw up breakfast soon after eating. He has not been able eat anything. He has not pooped today, is irritable, whining, and very lazy. He is not himself.

Liz Elias from Oakley, CA on March 04, 2015:

Congrats on HOTD! Very comprehensive and well-done article.

Oh, the things we never used to know, and those ever-present "exceptions to the rule!" A couple of examples:

When I was in high school, we had a boxer-mix dog, who loved grapes. He and my dad would share a snack, "one for you, one for me..." and if my dad took two in a row for himself, the dog would bark at him! No ill effects ever suffered. LOL

When my dad was a young man, in his bachelor days, his sister had a Boston Terrier, who dug up and at all the garlic plants in the yard, with no ill effects...except to the humans into whose faces he then breathed! Yuck!

My dad said he had a dog (in his teen years) who loved lived to be 20. Etc..

But, in the end, better safe than sorry, and best to feed your beloved pets only commercial pet foods...

Voted up, interesting, useful, pinned and shared!

Elsie Hagley from New Zealand on March 04, 2015:

Very interesting article, so many foods not suitable for animals. I wonder what they do to an unhealthy human body.

Congratulations for the HOTD.

James C Moore from Joliet, IL on March 04, 2015:

Dogs and cats are carnivores so it's intuitive that many plants that are good for us is bad for them. Also, I know pet parents who have taken their "babies" off of bones. But hubber Relationshipc has a point. It seems the occasional veggie should not hurt our predatory pets. This is obviously well researched and dare I say give us "food for thought."

Marcy Goodfleisch from Planet Earth on March 04, 2015:

Great list, and very informative! Congrats on the HOTD - this is a unique hub and one that all cat owners should read!

Maren Elizabeth Morgan from Pennsylvania on March 04, 2015:

I love your formatting.

Kristen Howe from Northeast Ohio on March 04, 2015:

Great hub on what not to feed your pet and its potential health hazards too. Well-written and well-researched on this informative and interesting hub. Congrats on the HOTD award mention! Kudos and voted up!

Nico from Ottawa, ON on March 04, 2015:

Very interesting article. My new kitten seems to like eating everything so I'll be careful of these foods.

Stephen J Parkin from Pine Grove, Nova Scotia, Canada on March 04, 2015:

I wonder if feral cats know what not to eat? I never feed my dogs anything that is not classed as and sold as dog food, but sometimes I wonder about even that!

Jennifer-Louise from Nottingham on March 04, 2015:

Such an interesting, thorough read. Thank you! I feel a lot more clued up. I don't have any pets myself, but there are two cats that like to make an appearance in our shared garden. Bless them.

CASE1WORKER from UNITED KINGDOM on March 04, 2015:

Thank you for this informative hub- luckily our cats don't like anything on this list preferring delicacies of meat with cooked vegetables . A must for any pet owner to read

Kari on March 04, 2015:

I have been feeding my dogs a raw diet for the past 15 years. We don't just feed undercooked meat, we feed RAW meat! GASP! Of course the meat is not full of hormones or other unhealthy things people eat.

We also feed the super deadly broccoli to our dogs. They love it. We don't give them a plate full of broccoli, but we do give about 15% of their foods as vegetables such as broccoli, carrots, and fruit like some banana or berries.

And garlic? That can actually help dogs with an infection. We have given it to our dogs in reasonable amounts and they are still alive.

Pet owners need to educate themselves about what is healthy for dogs and what is not. This list is a good start, but it is important to know that real food is dog food. 'Pet food' is something that was made up for convenience and money.

It's interesting. We have been attending a conventional/holistic veterinarian for years, and despite the knowledge and experience that they have passed on to us, some people we know still believe that there is such a thing as human food and dog food.

There is just food.

Some food is poisonous to dogs (most of which is poisonous to us too), especially in large amounts, but seriously - people who think that processed, nutrient-lacking kibble is good for their dog and then preach about how real food is bad, is so sad in my opinion.

Think about it this way: That kibble starts out as real food apparently. The commercials promote tender bits of meat and vegetables and fruit, but give you a hard and processed kibble?

How can people believe that little pellets of food is going to supply a living being with the nutrients they need to stay healthy? It doesn't make any sense! We need to stop the madness around 'pet food' and start giving our dogs, cats, and other pets the actual foods they need to survive.

Patricia Scott from North Central Florida on March 04, 2015:

Important info for everyone who has pets to know.

We can never be too careful about our little poochies and kitties.

Congrats on HOTD Angels are on the way to you this afternoon ps

Chin chin from Philippines on March 04, 2015:

We recently got a dog in our house. Nice to know about this info. So a dog is really better off eating dog food only?

whonunuwho from United States on March 04, 2015:

Thank you for sharing this. Very informative and voted up. whonu

Anna Richmond from Fort Wayne, Indiana on March 04, 2015:

I had no idea there were so many food products that are toxic to animals. I knew the basics like grapes and chocolate, but some of the items on the list surprised me. Great hub!

Brendan Michael Cronin from Quincy, Massachusetts on March 04, 2015:

Very useful Hub! It's good to get the heads-up on some of these potentially harmful consumables. Thank you!

Victoria Lynn from Arkansas, USA on March 04, 2015:

Congrats on HOTD! It's good for pet owners to be familiar with this list. Do you know WHY grapes and raisins are toxic? Some chemical in them? Thanks!

Governor's Academy for Engineering Studies from Virginia on March 04, 2015:

This is very helpful information. Glad to see it as HOTD.

Schatzie Speaks (author) on October 09, 2014:


I never "let" my dog eat road kill. And I never have her off a leash either. oh, and I love her too, btw. you try saying no to a 80lb lab on a diet who just discovered a rotting animal right near where she has decided to sniff in the bushes.

Schatzie Speaks (author) on October 09, 2014:


I am happy I could help out you and your pooch! :)

Schatzie Speaks (author) on October 09, 2014:

Vibesites--luckily it was only a little piece. sometimes even little pieces can be problematic since what is little to us is much bigger to a cat! so I am also glad he is ok!

Sherry on October 05, 2014:

i for one would not let my dog eat road kill,gross.i don't let him go out side with out his daddy ,then he is on a lead .i love my baby so much.

Flybyeme17 on March 19, 2014:

Wow! Some I already knew but a lot I didn't! Appreciate the info and time you put in it! U may have just saved my dogs life! :)

vibesites from United States on December 11, 2013:

Oh my I remember feeding my cat a small piece of chocolate. Glad he didn't suffer. Now I know... Thanks for your life saving hub

Schatzie Speaks (author) on September 21, 2013:


It is scary, I'm almost afraid to give my dog a sample of anything I eat just in case! But since she's a lab I'm not too seems like she can eat anything (plastic, paper towel, paint) and be just fine!

Thanks for the comment :)


Schatzie Speaks (author) on September 21, 2013:


Thank you! I tried to make it as comprehensive as possible and not leave anything out!

KenWu from Malaysia on September 20, 2013:

Thanks for this list. To be truth, it really scares me. Never know that food that might be beneficial to us can do so much harm to our pet.

Kenneth C Agudo from Tiwi, Philippines on September 05, 2013:

perfect and complete =)

Well researched. nice to know those stuff

Schatzie Speaks (author) on March 16, 2013:

Hi Catherine,

I am glad you found it useful. As an animal lover I am happy to do anything that could help prevent a tragic pet-related accident!

Thanks for the follow. :)

Catherine Stolfi from Long Island, NY on March 08, 2013:

This is a very informative and comprehensive list. Thank you for compiling it and including the symptons list as well.


Schatzie Speaks (author) on January 18, 2013:

Thanks, gags3480! I am glad you found it useful and hope you will spread any newfound knowledge among your pet-owning friends! It is so easy to accidentally feed a dog or cat something you shouldn't!


GAGANPREET SINGH BHATIA from Kanpur, India on December 27, 2012:

Really useful information. Shared it & following you now.

Schatzie Speaks (author) on October 23, 2012:

Hi Lioness! Thanks for reading and leaving a comment!

My puppy ate part of a decaying iguana just yesterday...she threw up a little but then went right back on playing with her toys. I've also seen her eat other dead things and have no noticeable problems.

From what I read by the experts, raw meat (other than salmon) doesn't have permanent negative effects, but can result in diarrhea or vomiting if it is contaminated (one would hope that store-bought cuts would not be laced with bacteria, but you never know).

As for road kill, when it died/how long its been lying around festering is probably a factor in whether a dog would get stomach upset or not.

Schatzie Speaks (author) on October 23, 2012:

An AYM-I've heard of people giving their pets alcohol too. I don't think they realize the risks or what could happen if they gave them just a little too much!

Lioness on October 22, 2012:

Thanks for the info! I would like to differ on raw meat though - many dogs do well on the BARF diet.

My last dog regularaly ate road kill (that is what she survived on most of the summer), and she had perfect health.

An AYM on October 22, 2012:

That is true, people sometimes tend to feed animals with the same foods they give themselves (Which typically isn't good). Whenever I see or hear of someone giving beer to a dog I want to smack that person upside the head.

No worries, it doesn't seem like any language stronger than "Silly" would be necessary or called for!

Schatzie Speaks (author) on October 21, 2012:

Thank you, An AYM, for your constructive criticism. I really do appreciate it. I think a reminder to pet owners to limit salts, fats, and nitrates in their pet's diet is never a lost cause. But you're right in that it's more about diet balance than toxic foods to avoid...although those things can sicken your pet. I'll relook it over in a bit and do some tweaking here and there. BTW that you for saying "silly" and not using a stronger term. :)

An AYM on October 21, 2012:

I get why you put it in there, but it's kind of silly to include meat and fat in a list of foods that can sicken and kill your pet.

Poisonous Plants & Foods for Dogs & Cats

Poison = bad… but our pets don’t always play by the rules.

Animal Poison Control Center

Pet Poison Help Line: 800-213-6680 [charges may apply] and/or: ASPCA: 888-426-4435

Every year there are thousands of cases of dogs and cats dying from being poisoned in the US and throughout Canada, and a lot of the time, it’s caused by things you may not expect. Here’s a quick refresher on some major groups of poisons to keep out of reach.

People Food

Some of our favorite treats, like chocolate, avocado, nuts, grapes and raisins, sugar-free sweets (with Xylitol as a sugar substitute), and alcohol are all poisonous to non-humans.
Even seemingly healthy plants like onions and garlic can be toxins to pets, whose bio-chemistry and metabolism are different from ours.
Look for vomiting, breathing problems, diarrhea, or weakness as symptoms that your pet may have snuck a snack off of the counter.

House Plants

Some common poisonous houseplants include
• Azaleas,
• Lilies (especially Tiger, Day, Asiatic, Easter, and Japanese Show lilies),
• Daffodils,
• Sago palms,
• Tulips
• Hyacinths can cause anything from mouth irritation and drooling to severe stomach damage or death.
• Poinsettias, are indeed not super healthy for them, but only mildly so.

• ** See more comprehensive listing of Poisonous Plants for Pets at the bottom of this article.

Lawn and Garden Products

pesticides, and
soil additives

is also known to be poisonous to our pets. As organic elements in compost decompose, mold often grows, which if ingested, can cause vomiting, tremors and seizures.

Household Products

Cleaning and other household products like bleach, paints, antifreeze and pool additives, as well as rat or other pest poisons can, of course, cause problems if ingested, and even chemical burns externally.
Symptoms of poisoning can vary, based on the size or type of pet, and the kind of poison ingested. General symptoms can include:
• Vomiting
• Diarrhea
• Seizures
• Blood in the stool
• Lethargy
• Loss of appetite
• Bruising
• Nosebleeds
• Irregular heartbeat
• Inability to urinate
1. Check your pet’s body and mouth to remove any remaining poisonous matter.
2. Try to collect a sample of the poisonous element (including anything your pet may have thrown up).
3. Get to your vet immediately. It’s always a good idea to keep the number of an emergency or 24 hour veterinary doctor or hospital at the ready in case of the unexpected after hours or on weekends.

DO NOT give your pet milk, peanut butter, vegetable oil or other soothing or vomit inducing substances. Do not attempt to induce vomiting unless directed by a veterinarian. In some cases, vomiting can make the problem worse.

Flea and Tick Products

Fleas and ticks are a commonplace concern when you have pets, and we look to remedy the problem in lots of ways, from pills, collars, and topical solutions, to bringing in the exterminator for large-scale treatment. But be aware that if the fleas are dying or jumping ship, you may be using potentially poisonous chemicals. Always check the dosage to make sure that you’re not harming your pet along with the pests, and seek out green or organic treatments. There are lots of pet friendly exterminators out there who can treat your home without endangering the other inhabitants of the house.

People Medications

Never share your prescription anti-inflammatory, pain and blood pressure medications, or antidepressants with your pets.
Even common over-the-counter medications such as acetaminophen (Tylenol), ibuprofen (Advil), naproxen (Aleve), as well as common herbal supplements like fish oil can affect digestive and cardiovascular systems in our pets.
Yes, there are some people medications that can be taken by dogs (like topical ointments), always check with your vet before opening your medicine cabinet.

Pet Medications
Just like people can overdose on drugs that were intended to heal, pets can, too. Some of the vet-prescribed solutions that are ofen taken over the recommended dosage include painkillers and de-wormers. Always double check the directions for your pet’s species and weight before administering, and check with other members of your household to make sure your pets hasn’t already received their daily dosage.

Plants that Can be Dangerous to Some Pets

Aloe: More than 500 species of aloe exist, all containing toxic saponin, which acts as a defense mechanism for the plant. Signs your pet ingested aloe include vomiting, diarrhea, loss of appetite, tremors and a change in urine color.

Amaryllis: Part of the lily family, it contains the highly toxic lycorine, which will cause your pet vomiting, depression, diarrhea, abdominal pain, hypersalivation, anorexia and tremors. This is definitely one of the plants toxic to dogs and cats.

Autumn Crocus: Another common name for this pretty pink flower is the Meadow Saffron. Although it contains colchicine, which is currently being studied as a cancer medication for humans, it is one of those plants toxic to cats, dogs and horses. Signs of ingestion include oral irritation, bloody vomiting, diarrhea, shock, multi-organ damage and bone marrow suppression.

Azalea / Rhododendron: Consisting of 250 different species, azaleas are quite common, especially in California. Despite the plant’s petite size, the flowers can cause problems in cats, dogs and horses. It contains grayanotoxin, which alters skeletal muscle, cardiac muscle and nerve function. This interaction causes a multitude of side effects which could result in coma and death.

Carnation: Who knew that the most common flower found in bouquets was among the plants toxic to dogs and cats? Although the toxic variant is unknown, carnations will cause your pet to have mild dermatitis and demonstrate mild gastrointestinal signs.

Castor Oil Plant: Typically grown in California to produce castor oil, this plant’s leaves resemble ivy. Known for its uniquely spiked seed capsules, it contains ricin, which is not only among the plants toxic to dogs, cats and horses, but humans as well. Ricin inhibits protein synthesis, and even if your pet consumes as little as one ounce, the effects can be lethal. If not treated immediately, your pet may experience convulsions, which will eventually lead to coma and death.

Chamomile: No matter how relaxing it is for you, don’t let your dog, cat or horse get a hold of your chamomile tea! This flower contains a variety of toxic components and will result in your pet experiencing contact dermatitis, vomiting, diarrhea, anorexia and allergic reactions.

Chrysanthemum: Often called “mums,” his common garden flower belongs to the daisy family, and is one of the plants toxic to dogs, cats and horses. Clinical signs that your pet has ingested chrysanthemum are vomiting, diarrhea, hypersalivation, incoordination and dermatitis.

This pretty flower, most commonly known for its vibrant buds and unique contrasting leaves, is among the plants toxic to cats and dogs. Small ingestion side effects include diarrhea, vomiting and salivation. If your pet consumes a large amount, however, your pet will experience heart rhythm abnormalities and seizures, which may eventually lead to death.

Dahlia: Another beautiful flower that ranks among the plants toxic to dogs and cats are dahlias. Although not as high in toxicity as some of the other plants mentioned, this flower will cause your pet to experience mild gastrointestinal signs and mild dermatitis.

English Ivy: This type of foliage is one of the most commonly used in households. We can see it growing along the sides of walls and fences among our backyards, making it easily accessible to our pets. It is among the plants toxic to cats, dogs and horses, and will cause them to experience vomiting, diarrhea, abdominal pain and hyper-salivation.

Eucalyptus: This plant is commonly used in many oils that we humans use for aromatherapy and skin care products. However, it is among the many plants toxic to dogs, cats and horses. If your pet consumes this plant, they will experience salivation, vomiting, diarrhea, depression and weakness.

Foxtails: Foxtails are not a plant you would purchase, but in certain states, in warmer months they can be seen everywhere. A foxtail is a “spikelet” that grows on certain types of grasses and attaches to your pet with special barbs. A foxtail can work itself under the skin causing internal damage and death.

Gladiolus: This, too, is one of the plants toxic to dogs and cats. Ingesting any part of this plant will cause your pet to experience salivation, vomiting, drooling, lethargy and diarrhea. However, the highest concentration of its toxic component is in the buds.

Hibiscus: If your pet eats this tropical-looking flower, they will experience vomiting, diarrhea, anorexia and nausea.

Holly: This plant, found in many of our holiday decorations, contains a low toxicity in its berries and leaves. However, it is still among the plants toxic to cats, dogs and horses, and will cause them to experience vomiting, diarrhea and depression if ingested.

Kalanchoe: There are over 125 different species of kalanchoe and they all look very different! Kalanchoe is among the plants toxic to dogs and cats alike, and most commonly will cause them to experience vomiting and diarrhea. In rare cases, your pet may experience an abnormal heart rhythm.

Lilies: While flowers derived from the lily family are toxic to many species of animals, the most common lily that we all know and love is toxic to cats only. If your feline ingests this flower, they will experience kidney failure which, if not treated quickly, may result in death.

Marijuana: The Delta-9-THC that exists in marijuana, which causes an altered state of mind in humans, has the same altered-state effect in dogs, cats and horses. However, this effect is not good for animals, making marijuana one of the plants toxic to dogs, cats and horses. You can tell if your animal comes into contact with this common drug by seeing them experience prolonged depression, vomiting, heightened excitement and/or sleepiness, incoordination, hypersalivation, dilated pupils, low blood pressure, low body temperature, seizures and a possible comatose state. In rare occasions, ingestion of marijuana has resulted in animal death. Keep the brownies for human consumption only!

Milkweed: There are many different species of milkweed however, this plant is most commonly known for its hollowed filaments covered in wax. It is the plant that is most commonly cultivated for the stuffing in our pillows! Although this plant sounds cute and harmless, it is another one of the plants toxic to dogs, cats and horses

but not butterflies. It will cause them to experience side effects which may result in seizures, difficulty in breathing, weak pulse, dilated pupils, kidney or liver failure, a comatose state, respiratory paralysis and death.

Morning Glory: Morning Glories come in over 1,000 varieties. This beautiful flower contains hallucinogenic alkaloids in its seeds. If ingested, it can cause your pet to experience gastrointestinal upset, agitation, tremors, disorientation, ataxia and loss of appetite. In some cases it may cause diarrhea. This is one of those plants that you really have to watch out for, because many of these side effects can go unnoticed.

Mulch: That’s right, you don’t just have to worry about plants toxic to dogs and cats. Many other natural materials are toxic too. Don’t worry too much when it comes to mulch, though, as not all fertilizers are toxic to your pets. However, cocoa mulch, typically sold at many home improvement stores, is toxic. It contains theobromine, found also in chocolate, and has the same side effects that would occur from the consumption of chocolate.

Oleander: This typical Californian plant, known for its long stiff leaves, contains a component known as cardiac glycoside, which means it is one of the plants toxic to cats, dogs and horses. Although this component is used in medicine to treat cardiac failure in humans in pets, cardiac failure may be the result. Signs that your pet has ingested this highly toxic plant are colic, diarrhea (possibly containing blood), sweating, incoordination, difficulty breathing, muscle tremors, the inability to stand and as mentioned before, cardiac failure which may result in death.

Peace Lily: A popular houseplant and common bouquet filler, the peace lily is known for its single spiky spades, surrounded by a single white, yellowish, or greenish leaf. It’s also one of the plants toxic to dogs and cats. If your pet consumes this, you will notice them experiencing oral irritation, intense burning of the mouth, tongue and lips, excessive drooling, vomiting and difficulty swallowing.

Poinsettias: Myth/Fact?…..Are poinsettias poisonous to cats? As it turns out, despite their fierce reputation for making kitties sick, they’re actually one of the weaker offenders on this list. However, while generally overrated in toxicity, poinsettias do contain sap that may cause irritation to the mouth and stomach, and possible vomiting.

Pothos: An ivy plant, most commonly found inside the house as decoration. This is definitely one of the plants toxic to dogs and cats. If your pet ingests this, the side effects include: oral irritation, intense burning and irritation of the mouth, tongue and lips, drooling, difficulty swallowing and vomiting.

Rubber Plant: Not all rubber plants are toxic to your pets. It depends on the genus and species. Rubber plants from the Peperomia genus are not highly toxic to your pets, however, they may cause a mild stomachache. Other rubber plants, such as the Japanese Rubber Plant, are among the plants toxic to cats and dogs, and may cause diarrhea, vomiting, depression and lack of coordination.

Sago Palm: Another plant that many of us use in our landscapes is the Sago Palm. Although difficult to ingest, if your animal gets a hold of this plant, it could be fatal. This is among the plants toxic to dogs, cats and horses in an extreme way. Signs of consumption include vomiting, bloody stools, jaundice, increased thirst, hemorrhagic gastroenteritis, bruising, bleeding disorders, liver damage, liver failure and death.

Schefflera: More commonly known as the Umbrella Tree, this tropical-looking plant is definitely among the plants toxic to cats and dogs. It contains calcium oxalate crystals, which is a common cause of human kidney stones! This toxic component is found in every part of the tree and will cause your pet to experience oral irritation, excessive drooling, vomiting, difficulty swallowing and intense burning of the mouth, lips and tongue.

Shamrocks: Consider your pet unlucky if they get a hold of a shamrock. This is one of the many plants toxic to dogs, cats and horses. Although only slightly toxic in small quantities, a large consumption of this plant by your animal can produce colic (in horses), and possible kidney failure (in all three types of animal). Don’t let this dampen your St. Paddy’s Day celebrations!

Spinach: Who Knew? Spinach does contain a small amount of calcium oxalates, which could potentially cause the formation of crystals in the urinary tract of an unhealthy cat. If your cat has a history of urinary problems, Popeye’s favorite meal should be avoided completely!

String of Pearls/Beads: Known for its white flower buds, with tiny, purple bead-like structures standing up from the bud, this flower is toxic to cats, and possibly dogs. Symptoms include diarrhea, vomiting, muscle convulsions, loss of appetite and abdominal sensitivity.

Tulip/Narcissus Bulbs: Tulips are some of the most common plants that we try to cultivate ourselves, but they are actually one of the plants toxic to dogs, cats and horses. They contain a toxic component called tulipalin A and B which, if consumed, will cause vomiting, depression, diarrhea and hypersalivation in your dog, cat or horse. The highest concentration of tulipalin A and B exists in the bulb of the tulip, so keep your furry friends away!

Yew: Used in many Japanese-inspired gardens, the yew is definitely high up on the list of plants toxic to cats, dogs and horses, and can even be fatal. Onset signs of ingestion include muscular tremors, shortness of breath and seizures (in dogs). The fatality that may occur from consumption is sudden death from acute cardiac failure.

Yucca: Yucca is native to hot and dry climates in North America. They’re beautiful plants toxic to dogs, cats and especially horses, unfortunately. Ingestion of yucca causes different side effects depending on the animal. Dogs and cats will experience vomiting and diarrhea. Grazing animals, like horses, are even more vulnerable and will experience liver disease and secondary photosensitivity.

As the old saying goes, an ounce of prevention is worth a pound of cure.

I have fed my dogs table food all their lives, the oldest being 13, and have never once had a problem. It's no different than saying we should not eat certain crap

If you stopped eating all the stuff that's bad for you, then you would starve and have a boring life with just a few food choices

The only thing I refrain from giving my dogs is large quantities of chocolate

The onion and garlic thing is a real joke. They eat plenty of it without problems and my vet says the garlic helps deter fleas.

Can anyone point to any scientific studies? My vet said chocolate is a problem, but everything else is fine. A lot of old wives' tails here I think. anon939785 March 15, 2014

With all the comments above about "just don't feed your dog" this or that, apparently none of you have Weimeraners or other dogs that counter surf. It is next to impossible to not have an occasional ingestion of things. My Weims eat toilet paper, paper towels, cardboard boxes and plastic bags, in addition to edible products right off the counter that I've just turned away from for a second to grab a spoon.

One got 10 avocados off the top of the refrigerator. I wasn't home at the time so I assume she jumped up on the kitchen counter and from there to the fridge, where the avocados were resting in a brown paper bag to soften for guacamole. She ate the skin, pits and all. It took about 18 hours for her to go into toxic shock.

I have tried everything from discipline, training, and just plain making sure I don't leave anything out, but sometimes it's not always possible. I now keep a supply of peroxide on hand to initiate immediate vomiting and simethicone based products for gas to help avoid bloat. You do the best you can and hope for the best. anon321766 February 24, 2013

I fed my indoor cat a high-end cat food, EVO, for most of his ten years, with no problems. He loved it and it was good for him. Last summer he started throwing up occasionally, which was almost unheard of for him. The vet assured us he was fine and to keep feeding him this food. But he's been throwing up more and more often until this morning, when he threw up literally all over the bathroom floor. (He is an incredibly considerate cat and only throws up in the bathroom if he can make it there in time.) The vomit was the color and texture of partially-digested EVO. Today I am returning the unopened bags of EVO along with my testimony and other notes online about EVO users having the same problem.

Bottom line: I will never again feed my cat processed kibble or canned food. I fed him some plain roasted turkey and he wolfed it down. It seems more natural to feed him poultry and fish that is human-grade instead of kibble made in a factory. As for vitamins, NOW makes a tasteless, colorless powdered taurine supplement that can be mixed in water, and other supplements can be added to food. This will probably extend my cat's life as well as save a lot of money that wound up as vomit on the floor. anon291209 September 13, 2012

Cats are carnivorous. They aren't really meant to eat vegetable fibers and sweet things like fruit can be extremely unhealthy and can lead to diabetes. Also, fish isn't something a cat should eat all the time as it is really not that good for them to have all the time, although it is very important to have in the regular diet, but only to an extent, since the fatty oils and omega-3 are what the cat needs from fish, but too much can lead to obesity and intestine problems, so they are necessary but not all the time.

Also remember that cats cannot digest vegetable fibers as their digestive system does not have the proper enzymes to break it down. Most people would argue this is not true since wild cats eat their prey that have vegetables in their stomachs when the cat consumes it, although this is not the case, because cats usually do not eat the innards of animals, but leave the entrails behind. Even if they were to consume a portion or even all of the digestive systems of their prey, the vegetable fibers in the other animal's stomach would have already been broken down by that animals enzymes. If you must feed your cat vegetables because of the innate human nature to see them as vitamin rich health food (true for you yes, but not for your cat), then at least steam them first to break down some of the fibers, although refraining completely is the best option.

The exceptions to this rule are, of course seaweed and grass, although if I were you I would not feed my cat grass from the outdoors as it can contain harmful diseases (not usually but there is a small chance). I find that growing your own indoor cat grass is the best solution. Unlike other vegetable fibers, cats eat grass for a different reason and this reason is because it can actually help calm heartburn for the cat and most important, the chlorophyll in the grass acts as an anti-plaque and is good for the feline's dental hygiene.

Beef is a good solution for a good, hearty cat food, as well is chicken and pork (although be extremely careful with pork as it can, if prepared improperly, cause worms), and remember the reason dogs like the same foods as you is cause they are omnivores like you and I, but cats are not. They are strictly carnivorous, which means they like meat and meat only. My cat Galaxy has been on a strict home diet ever since he was weaned, and now at five months old, has a sleek and shiny soft coat, superb dental hygiene, no fleas or ticks, no worms, and his fecal matter looks the way it should – not squishy and not rock hard either (yes I check. Someone's got to clean his cat box). He had a check up last week and the vet said he had never seen a more healthy cat at his age. He's going to be a show cat so it's extremely important he is healthy, but all cats have the right to a healthy life and that includes yours.

They depend on you for a healthy life, so you have to get involved and find out for yourself what is good and bad, but remember your cat is only as healthy as you let it be. You are what you eat. anon277390 June 29, 2012

I have a cat and I have an invasion of ants. They say ground clove will keep the ants away, but is it toxic to cats by smell or ingestion? maggsd March 19, 2012

@anon81909: and his comments about the product "Plaque Off."

Wanting to provide the best for my two beautiful golden retrievers in terms of health and well-being, I purchased the above supplement just over a week ago. I'm heartbroken because they are no longer with me. They died after two/three doses of the so-called "supplement," within two days of each other. My first dog was rushed to the animal hospital but the specialist care couldn't save him. He was admitted on Wednesday afternoon and given IV fluids and IV antibiotics and bloodwork was done, no disease or abnormality found.

The next day, my second dog collapsed with what we thought was internal bleeding. Again IV fluids were started, bloods taken and our suspicion was confirmed, and they started a transfusion on him. They were side by side, but as sick as they were, I never thought they would pass away.

However, to my absolute shock, my first dog died that night. They suspect it was with either toxemia or septicemia. My second dog, who had three doses of the stuff, had gastric bleeding and deteriorated passing large amounts of malaena. The awful decision was made to save him any more suffering, and he died last night, two days after his brother.

After reading several research items, it seems there is a substance called carrageenan in some seaweeds that can cause severe gastric and systemic upset. It therefore seems undeniable that this "supplement" was the cause of otherwise reasonably healthy dogs succumbing to this awful product. anon238529 January 4, 2012

Honestly, this article is a bit flawed and somewhat on the extreme side, particularly in regards to the part about xylitol. My golden retriever (weighing approximately 70 pounds) once ate an entire large pack (20 sticks) of sugar-free gum containing xylitol and did not appear to suffer even the slightest stomach upset. She has since passed away (from old age, not anything food related) and we allow my new dog to eat table scraps containing mushrooms all the time and she has never experienced any problems.

Plus, I have a friend that feeds his dog chocolate cake pretty much on a daily basis without the dog having any digestive upset. Although I would certainly not recommend feeding your pets things like gum and chocolate cake, it is almost inevitable (unless you are going to leave your pet caged every moment they are not in your sight) that they are probably going to get into something they probably should not consume at some point and there's really no need to panic over it. I mean, if I had read this article after my dog eating that pack of gum I would have been freaking out thinking that my dog was going to die when in fact nothing happened at all.

It is good to be informed about foods that should probably be avoided but saying something as specific as "a mere 3 sticks of gum can kill your 60 lb dog" only pertains to like the most extreme case and will probably only panic some poor pet owner who is worried enough already. Just simply stating that ingesting xylitol can be harmful to pets and that a vet should be consulted would be more than sufficient and suggesting that the pet will be be "dead within 24 hours" is inappropriate and simply not true. anon236766 December 26, 2011

My cats likes a bit of chicken skin/fat. They are smart enough to leave a lot of it alone and rarely eat more than a mouthful.

However on one occasion my cat ate a lot of it and ended up hurling it up all over the floor -- too rich, I guess.

Also I was told I should put a little hemp oil (no not the drug)in her food as it was good for her, but it gave her the squirts, I guess some fats are not very digestible.

I have to say it is not fun sponging diarrhea out of the carpet.

Now I just use a little fish oil from a capsule or a dropper as directed by a vet and there is no issue. anon236764 December 26, 2011

I have a cat that goes insane over it. I heard in some countries they eat it after large meat meals as there is an enzyme in it that helps with digestion of meat in humans. I wonder if it would hurt cats. Obviously, they didn't initially feed it to her but she got into it and ate a good portion of a wedge.

I like it but don't get it often so I don't give her more than a teaspoon full as I like it too much too, but she seems to have no problem. Should I avoid this? She seems to like it more than fish! anon236763 December 26, 2011

So tomato greens are bad, but how about pepper plant leaves? They are a similar family of plant. My cats won't touch the peppers. Hell, most people can't eat them, but within seconds of me putting on of my potted habanero plants on the floor and turning my back, my cats will start eating the leaves like they are catnip or something.

I stop them right away and they have had no ill effects, but does anyone know if they that harmful?

How about nori, the dried seaweed wrap used in sushi? One of my cats flips out over that stuff and hasn't had issues. Again, I try to keep them away but if they see it out they get into it rather quickly.

This is a good article, but the comments and chatter seem to be ridiculous. I only have a BS in Biology, so I can only make this very simple. Cats and dogs are of the same bloodline as their counterparts in the wild, and they are carnivores by nature. Look at their teeth they are designed for cutting and chewing meat.

They do not roam the forests looking for chocolate, sweet berries, or sweet fruits they look for meat and fish, maybe some eggs.

"Candy" and "sweets" are relative terms made up by us. "Candy" to your cat would be a nice juicy piece of fish. If you want to treat them to something, give them some fish, turkey, chicken, lamb, ham, or take them to a large pet store, which is their "candy-kitchen". anon227951 November 7, 2011

Garlic is not much of a problem in dogs.

You can pick out the "CYA" variety of vet by asking them about garlic. It's commonly prescribed by veterinarians today and has been used for centuries for dogs with fleas and also simply as an ingredient in treats, or an ingredient in people food that dogs eat without any problems.

Extremely large quantities of garlic, such as an entire bulb in one day, would cause problems, but even amounts as large as a clove per 30 pounds of dog doesn't seem to cause problems. Most times, the dog gets a tiny fraction of that, and benefits.

Onions in small doses are also unlikely to cause a problem, but should be avoided if possible.

Grapes, raisins and chocolate are to be avoided completely.

Many of the things mentioned in this list won't harm your pet at all. Many of them are beneficial. Unfortunately, we live in a strange culture where people will accumulate rules to live by without a good basis. Just because a pet died near the time it ate a tomato doesn't mean the food caused the problem.

With many millions of pets, most serious risks have studies explaining them, so you can easily weed out the silly from the serious. anon226879 November 2, 2011

Every animal may be more or less allergic to these things differently, so even if say, your cat ate tomatoes each day doesn't mean you should feed every cat tomatoes. It's still bad for them.

Just don't feed pets any of these! At all!

The garlic issue is a simple one. Onions contain Thiosulphate, garlic's compound is diallyl thiosulfinate. A very similar name, but chemically very different. Garlic does not affect platelet function, which has ben tested, and proven.

Onions, on the other had can cause hemolytic anemia in animals, due to the effects it has on the red blood cells. Please have facts before you post. anon182423 June 2, 2011

my six month old labrador pup got very sick yesterday. took her straight to the vet, and he said it was a toxic poisoning. he asked about all of the rat baits etc which i had none of anywhere near.

it got me thinking of what else is around the house, then thought of the toadstools in the back yard, so I did a bit more research into these and have found that yes, the toadstools that i have are, in fact, poisonous to dogs and have been known to kill them. in my case Nix is still alive, which the vet did not think she would be. apparently i need to buy a lotto ticket for that, but this is a warning to you all: if you have anything that looks dangerous to your dog, pull it out. anon163632 March 28, 2011

I was once looking up some information on Comet Cleaner with Bleach Disinfectant and found people commenting about eating it (don’t believe me, just look up eating comet cleaner). It sounded insane to me but there were people commenting on how they had eaten it for 15 years.

My point is just because someone does something stupid, and hasn't died from it yet, does not mean that it's something that one should do. Even if there's someone who drinks a glass of bleach and lives to 100 years old, it doesn't mean that this is the secret to old age. It means they were incredibly lucky. This goes as well for people who drink and smoke all their lives and die at 99. Yes, they got lucky, but there are a hell of a lot more people who drink and smoke their whole lives and die at 50 or 60.

So sure, maybe you had a cat or dog to whom you fed chocolate or garlic or whatever for 20 years. The fact that they lived that long probably means that their body was incredibly resilient, not that it did them a lot of good.

Why would you purposely feed your animal a food that is known to be toxic to most animals? What is the point? Does it make you feel good to make your animal sick? To put stress on their bodies by making them eat things that are not good for them? If you are really too cheap to buy pet food, fine, feed them human food, but at least stay away from the things that are bad for them. Better yet, don't get pets. anon163474 March 28, 2011

Feeding chocolate to a dog as a way of a "peaceful death" is a crime. You could have surrendered him to a shelter instead of poisoning him! What city do you live in so I can report you?

Some of you handily solve the concerns over which foods are dangerous or not with the suggestion to "just feed your pets pet food." I'd hate to see your diets! What do you think these animals have been doing for thousands of years? Running down to the store for some Purina?

It seems like the healthiest diet for your pet would be the one which you know the most about, i.e., a nutritionally-informed homemade diet. Now of course this isn't the most convenient for everyone, but to knock it is just being way out-of-touch with the real world. And don't forget that our pets aren't always eating those foods which we allow them to have - they get into things on occasion - and a little information can go a long way you need to know those times when you may want to give your vet a phone call.

Oh, and to say something like "my pet likes chocolate"? My ex-girlfriend loved the crap out of some Xanax but I'm pretty sure that only made her stupider. anon158616 March 7, 2011

Seriously why are people still writing "but my dog had this and he is fine and my cat had this but she is OK". Clearly it is harmful otherwise this wouldn't be a subject of discussion.

What this person is trying to say is these foods are not good and will be a risk. Your dog or cat may be absolutely fine after giving it some of these foods but it's the next animal that won't be and you don't know if that's going to be your pet or not. If you want to take the risk good on ya, but you wouldn't take that risk if it was your child (i hope), so just avoid it.

What's the big deal? you all just want to debate about it. It's annoying. these people have gone to uni for 3-4 years to know these things, so just stop questioning it! anon157673 March 3, 2011

Chocolate isn't a toxin - it contains a toxin. While it's true that milk chocolate, for example, contains less of the toxin than the same quantity of dark chocolate, neither is okay. Further, feeding little bits over time is actually just as harmful as a single large dose because the chemical's effects are actually progressive - the more they eat it, the worse it gets. Stop feeding your dog chocolate!

Any member of the onion family - garlic, onions, shallots, scallions, leeks - they are all bad.

Interestingly, turns out poinsettias are not toxic. Every report of poinsettia toxicity points back to a single study done about 60 years ago. That study turns out to have been incomplete and wrong - and all evidence people cite to support the claim references back to that one study. Who knew? anon156544 February 27, 2011

Our dog Bear was a chow. We got him as a small pup he died a month before his 20th birthday of sudden heart failure in his sleep (Basically old age). The dog loved and I mean loved chocolate. He ate it daily. We fed him Pedigree, but honestly he mostly ate table food. He had his eyesight when he died, all his limbs, and was very active and healthy.

Fast forward six years and now I have a Border Collie I got as a Parvo Rescue puppy at six weeks. She is soon to be five. Look at her cross eyed and she gets diarrhea. We keep a can of pumpkin here at all times and the poor thing has had so much rice and stewed chicken that she turns her nose up at it. Open the medicine cabinet and she trembles from having to had so many meds.

We feed her little to no table food, much less chocolate, yet still she has to make two to four emergency trips to the vets or the vet hospital every year. I walked the floor with her at six weeks for a week, administered IVs to her here, had her a blood transfusion at the vets. It was a horrible time. Her blood count was down to 1,250 at one point.

She's a little fire ball now, and my favorite because she fought so hard to live. However, my vet says the rough start with the Parvo has no bearing on her health today. I strongly disagree. Having dogs my whole life (We always have two or three at once) I have never seen one as sickly as her. Last year she was walking through the hallway and just fell over. She had no use of her back legs all at once. Well there went a $150.00 visit to the vet emergency room. They said she had a virus, and gave her antibiotics in two days she was fine.

Point being, I believe it's really a dog to dog issue on their health. She has supplements, and almost constant vet care, yet she still struggles. Bear not only ate chocolate daily but we found him sneaking into stored wine drinking it, and continued to let him drink a shot of wine for 15 more years and he lived to be almost 20. anon156340 February 26, 2011

It has honestly never crossed my mind "what is and what isn't OK for my cat to eat?" I've always fed my cat nothing but cat food. Plain and simple.

I always discourage him when he begs for food and make sure he doesn't eat "human" foods. He's 20 this year and still as healthy as a kitten so it's that simple. Don't worry about what is and what isn't OK for them. Just stick to the cat food and your cat may live as long! anon150131 February 7, 2011

One of our cats loves bread but has been throwing up over barley bread, so I guess barley is toxic. He adores cucumber, and so far I've heard that it is okay, but what about red and yellow peppers? He also loves beetroot.

We're never going to let him eat raisins again, and I'm not sure how good coconut is, which is also one of his favorite snacks.

I can tell you first hand that grapes and raisins are horrible for dogs. My dog ate a grape and vomited about every two minutes all night long.

Firstly, garlic which has been cooked or processed into powder form, is very safe and good for dogs. Tomatoes are healthy too, however the stem/ stalk is poisonous best thing to do is to remove this before feeding the dog.

Potatoes (except yellow spuds, i.e. 'Yukon Gold') and sweet peppers are very healthy.

Thirdly, never give your dog chocolate- period, end of story.

Avocado: Good, but seed is toxic.

Carrots: Good, but best shredded or steamed for better digestion (avoiding digestive problems).

Greens: Good for dogs as the are for us, especially as dogs mature, they gradually require less protein with age, so mixed greens is best (i chop and add kale, chard, spinach, and broccoli, etc.) --j anon135585 December 19, 2010

A response to some comments on this page:

Commenter 18: Any amount of chocolate is too much. It may not kill them, but it teaches them to eat chocolate.

Commenter 28: Watch your language- it is not "more allergic". I understand what you mean, "more poisonous", but chocolate is not an allergy, it is a poison. Arsenic is not an allergy, it is a poison. Same thing.

Commenter 33: You do not "build up an immunity" to poison. You can for sickness, but chocolate is not a sickness, it is a poison. Also, dog and human digestive systems are different. So don't think that because you can eat chocolate, it is good for your dog. Toby has not built up an immunity to poison, and never will.

It is not simply a question of exposure. This is possibly one of the stupidest comments posted on here. That guy who died on the news from poisoning? Poor fool. He should have eaten more poison. Then he'd have exposure, and he'd be all right. If it were simply exposure, do you think it would be listed as a poison?

Commenter 43: I am reading my cat's food ingredients. Chicken meal, corn gluten meal, ground corn. Hmmm.

Commenter 53: Chocolate is harmful, and most kinds of chocolate takes much less than "half their body weight". But you are right about garlic.

Commenter 84: That seems kind of harsh. Unless your dog lives out its life in a bubble, they will get into something they shouldn't, and it's not the owner's fault. But you can be okay if you try carefully, then what your dog might get into will be minimized and shouldn't be harmful.

Commenter 91: Potato peels are not good for your dogs! If you stand by and feed them peels as treats, shame on you!

Commenter 100: I am 107304. I have had cats all my life and know how to care for them. Care for them by simply feeding them their cat food, water, and any medications they need. If you complain about adding "flavor" to their diet, ask your vet about which foods you can give them.

Commenter 109: You tie with Toby's owner for silly comments. You are right, but you shouldn't give them tiny bits of chocolate, because they will then think "Oooh, here's this stuff my owner gave to me! And there's so much! Wow, even though they only give me little bits, they always give me good stuff! This, therefore, must be awesome! Let's just snarfle it down!" and there goes the Twix bar and your pet's health.

Commenter 111: I have mixed feelings about you and your friend. I am sorry for her, but chocolate is not a cheap alternative for euthanasia! Do something. Give it to a Humane Society. Plead your situation to a vet. But chocolate is a horrible way to die. You do not poison your pet to save money! You do something!

And as for you, I'm not even sympathetic. You don't just stop caring about your cat's health because they were okay that one time! Ugh, you are not a responsible owner.

Commenter 113: I think your name might begin with S, am I right? I think I know you, and you might be my sister. But you are a genius, an absolute genius. Commend yourself for your brilliance. You are one of the sane people on this commenting site. And all other people who agree with her- if she is who I think it is, it's a she- you are genii too. Pat yourself on the back!

116: Here is your answer. Quantity. I have wondered too, but I think it is because they only put tiny amounts into it. But regardless, I would trust the manufacturers, because other dogs eat the stuff, and they all seem okay. But don't give your dog garlic or onions on your own. You can also ask your vet.

Commenter 120: Grass is commonly thought to be a stomachache cure for cats, but it is not. Why do they eat grass? Because they like it! It probably does help them, but they don't know it. They just like eating grass.

Commenter 122: You are also a genius. If you are not on this comment, you are probably also pretty smart. Pat yourself on the back!

And finally, my own opinion. I think that you should just not feed your dog or cat stuff on this list! Don't think of other occasions where they've been okay. They can survive little bits, so make sure they don't get any of the stuff again!

It really isn't that hard. Or, talk to your vet, and don't trust people on the Internet who say chocolate is okay! well, that might mean you shouldn't trust me, but then I suppose that's okay. Just talk to your vet! Think about it. If you're talking, in person, to someone who knows about animal welfare, trust them! Not people on the internet!

And a warning about walking down primrose paths: seeing is not believing on the Internet! Be kind to your pets. anon133065 December 9, 2010

I have to ask. Are people posting on here that ignorant that they can't accept that certain foods like chocolate or onions are poisonous and to keep them away from your pets.

I don't care how much you or your pet likes chocolate or grapes: do not allow them to eat them, end of story. You took on the responsibility to protect them, they can't read so it's your job!

Smarten up people, most of you make me sick. For the person who said her friend couldn't afford to put the dog down so gave it chocolate covered raisins, well, you're just not smart. The both of you should be brought in for animal abuse. anon132822 December 8, 2010

My dog took it upon herself to eat a half a pack of trident gum. We ended up taking her to the ER where they induced vomiting and found several pieces of gum in her system. They also found that her blood sugar was low.

They insisted on keeping her overnight to provide her with fluids to bring her blood sugar up and liver protectors to protect her liver from the gum's chemical of xylitol that she ingested. The chemical doesn't just bring down a dog's blood sugar to deadly levels but it also can severely damage the liver! Everyone needs to know how serious xylitol is and that it is found in almost every gum! anon131710 December 3, 2010

My dog ate a table full of Christmas chocolates, it was around 5 pounds of it, she was fine. she's a weimaraner/lab mix. 10 years later she succumbed to old age.

My kitten's first meal at his new home was spaghetti with sauce that had peppers, mushrooms and onions in it, he's a healthy 10 year old now, and still loves it. He also loves peas and green beans.

Animals are a lot smarter then most think. grass is a cure for upset stomachs to them, just don't use poisons on it. Everything here on earth has a meaning for it's being here, it just the stupidity of humans that make so many things bad.

anon131147: Most vet specialists say there is a special chemical in garlic and onions that is essential to cats and dogs. But, they can only have very very small amounts. More than 5 grams could be fatal to any size cat or dog. I believe they put it in weight loss dog food because of the fat working ability to burn fat as well as many others types of dog food and dog treats. anon131259 December 1, 2010

Onions especially, but garlic as well, contain thiosulphate - which is toxic, and can cause hemolytic anemia and liver damage. How the onion is prepared (raw, cooked, dry, etc.) doesn't matter. anon131147 December 1, 2010

Why are people worried about giving their dogs garlic and onions? I've read the ingredients on a can of dog food and it says garlic powder and onion powder right on the list of ingredients. I wouldn't give my dog garlic and onions if they are poison, but, you have to wonder why they put it in canned dog food if it is poison? anon130909 November 30, 2010

It has been stated that as little as 50g of dark chocolate can prove fatal to an average sized dog. Other chocolate products contain varying amounts of theobromine, but no amount is considered 'safe'.

Even sub-lethal doses can lead to your dog becoming very ill, disoriented, and in pain for a prolonged period following ingestion. Death by chocolate is extremely unpleasant indeed, and anyone subjecting their pet to this should rightfully be condemned for their stupidity and cruelty.

If you must feed your dog chocolate, make sure it's of the kind manufactured specifically for their consumption. anon130470 November 28, 2010

RE post: about rules about what to feed cats and dogs. Theobromine isn't poisonous to humans anon130469 November 28, 2010

Ahem. Just for the record, the commentator who says 'you can give your dog a taste of chocolate,' you can't. Because your dog, no matter how much you love them, is not smart enough to figure out that chocolate is bad for them. Meaning, sure, a little bit of chocolate won't hurt your dog, sure. But your dog will think 'oh, my best friend gave me this stuff. It's delicious!' and then it eats a bunch of really dark chocolate and can't figure out why you're freaking out. After all, you knowingly gave your dog poison. Your dog likes the taste of poison.

So, if you accidentally leave stuff out (I'm not calling anyone a bad owner if their dog gets into chocolate. Heck, it happens! You leave a chocolate cake out on the counter and when you next look it's on the floor, half eaten), your dog will be more likely to eat it, because you gave chocolate to them and he/she thinks it's okay to eat.

As for the commentator who said 'not everyone is an animal expert' then yes! Someone sees the light! Maybe a commentator was wrong when someone said 'you are correct about dogs but not cats', but they might be right!

Let's take the example of our friend who says that white chocolate has no theobromine in it. Chocolate is something you just don't give to your pets, because even though 'a little won't hurt them', it's the same thing as telling your child, 'come on Jessie, cyanide is delicious! Try some!'. So here is an example of a comment that sooner or later somebody will put on here:

I am a licensed vet, and I don't understand why people say that chocolate is poisonous. It's not. Anybody who gives their dog chocolate is actually giving them a well-needed staple of their diet, because like we sometimes consume tiny amounts of cyanide each day, consuming tiny amounts of theobromine per day is very good for dogs.

Now, nobody has said that yet, I've never seen that, but the point is, people can be all sorts of things on the internet. They can say that they are doctors, vets, and they might be! But this is proven toxic stuff. It's not like carrots.

You know, one person says 'ooh, carrots are awful for pets (no one has yet, I'm just *saying*), and the next person says 'ooh, carrots are great for pets!', and the debate can go on forever, because carrots are those things where it doesn't matter if your pet eats them or not.

But with chocolate-wow! Sooner or later somebody's going to come on here and say 'listen up you lot, this stuff is toxic! If you wouldn't give your dog cyanide, then how come you give them this stuff!' in fact, I think other people have said this and I'm saying it now.

Sorry if I'm going on a bit, but I hate it when people are dancing on the verge of 'let's give our dogs poison! Woo!'.

As for the commentator whose friend had to give their dog chocolate covered raisins to get the dog out of his or her misery, that is so sad. I'm sorry. My cat a long time ago once had to be put down. The sad thing is, I was out that day and I came home and found my family had had him put down. I didn't even get to say good bye. anon129919 November 26, 2010

Be good to your animals. point blank. I make my dogs homemade treats and am very careful about the ingredients I add. I use fresh fruit (apples) peanut butter, cornmeal wholewheat flour and 1 egg as a binder and for protein. I add no spices or salt, I just use natural food.

I remove the peels from the apple to remove as much pesticides as I can and try and by organic when I can. Dogs and cats like treats just like we do. Just be safe and do your research when making homemade treats for our Fur babies.

Feed them as if you would feed you own children. Be careful and conscience of all you put into there little bodies. they can not tell you what gives then a belly ache and just because they seem to enjoy it doesn't always mean it's good for them. when it comes to you animals always proceed with the greatest of caution! anon127550 November 16, 2010

I would never feed chocolate to a dog (along with grapes) but, ever since my cat stole my chocolate muffin-I haven't been so worried for him.

My cat is almost as much of a chocolate junky as I am.

Tough, sad story: My good friend's dog was suffering a lot from being so old and so weak that the vet suggested putting her down. My friend couldn't afford the bill. It was way too much. Shooting her was also out of the question.

So she fed the dog chocolate covered raisins so it'd be a calmer and cheaper death. anon127506 November 16, 2010

And for the record for everyone who keeps saying "Look it up," how about going to your veterinarian instead? Not every article written about animals is by a genius! Lol anon127504 November 16, 2010

There is nothing wrong with giving your dog a nibble/taste of chocolate. I'm not saying let him woof down a whole Twix bar, but just a piece half the size of a dime for the dog isn't going to do any kind of terrible death/damage to your dog. Chocolate is very bad for a dog, but a taste won't hurt him! anon121337 October 24, 2010

Excuse me commenter 107? You do your research. White chocolate contains theobromine. Granted, it does contain a very very small amount, but you still shouldn't give it to your pets on the grounds that 'a little won't hurt them'. Same with regular chocolate. It's the same as drinking a little bit of antifreeze and then saying 'oh, but a little won't hurt me!'

Just look up theobromine white chocolate and see where it gets you. And there are a lot of sites that will say the same thing as I said.

It's stupid to give cats and dogs chocolate. If you know it's bad for them, why do you give it to them? You can't rely on experience 'oh yeah, but my dog ate chocolate so much and she is like twenty!' I agree with the commenter who said 'lets all let our children run out into the street, play with matches, and take drugs since it may not be harmful every time they may do it' (sarcasm).

Now you're saying 'But they love the taste of antifreeze, chocolate, and other poisons so much! How can I deny it to them!'

Lay off the poisons. people who do give their pets poison are like a parent who gives their kid cyanide because 'it tastes so good.' anon119785 October 19, 2010

I'm anon107304 and im sorry if i said cats and dogs. I meant dogs. with, chicken and rice is amazing for dogs with upset stomachs. you get chicken, cook it totally bland, without any spices, salt or anything, then you remove the skin, stick it in a food processor till it's all chopped up. you cook some rice, mix them together in a doggie dish, ta-da! doggie food.

a big plus is that my dog likes it better then her regular food, and i think a lot of dogs would feel the same way. pumpkin also helps. Aby August 30, 2010

@anon107304: You are correct about dogs, but not cats. Go look it up. Anyone who is interested in some interesting facts about cats and how to keep them healthy should do some research on Lisa A. Pierson, DVM.

Regarding the owner of the shih tzu Toby, chocolate does not do that! It's like smoking. 'Well, I love smoking, and so does my friend. We've never gotten sick. We've built up an immunity to them.' Then, the next day, you find their lungs have turned black and they are now dead.

Chocolate is a poison. No one builds up an immunity to cyanide or antifreeze! And dogs can't build up an immunity to theobromine.

Compare it to getting a virus in your computer. You've got it, and all those months, it's just waiting. Then, Bam! You suddenly find something wrong with your computer. Since Toby has had chocolate for a while, maybe it didn't affect him that time. But don't take chances.

Yeah, you get the point. Also, was the chocolate white chocolate? White chocolate contains no theobromine and is therefore safe to give to your animal in small doses, though it is not recommended!

Honestly, I don't want everyone's dogs to die and then they say 'but you said it was safe'. If your dog somehow gets into it (which it shouldn't because you shouldn't have it out in the first place), the dog should be fine. Of course, if it's a lot they'll get sick because it has a high fat content, and lots of fat makes humans feel oogy and makes dogs really sick. (That, my friends, is why you don't give them turkey skin -- too much salt and fat.) anon107546 August 30, 2010

anon101754, I don't think curry powder is poisonous exactly, but I don't think it's really good for them. I think they might have diarrhea after you give it to them or something. Well, it's not recommended, but it won't kill them. anon107304 August 29, 2010

I saw some stuff and I want to clear things up. So, anyone reading this, don’t try stuff on your cats and dogs just because someone on the internet said so. Anon661, if you saw something poisonous, like a poisonous berry, then do you instinctively know it’s bad? Do you instinctively know that sugar makes you fat? No. Same with your cat. Also, i saw a post on here that said “cats and dogs are carnivores, they should never have veggies”. Well, take a look at your cat or dog food. Read the ingredients. Notice anything odd? Cats and dogs have survived on manufactured food for quite a while, and it’s not all meat.

And i want to clear something up about chocolate. The thing that makes chocolate poison to dogs and cats is both theobromine, and caffeine. So, never let your dog have coke, or tea, or coffee, or anything with caffeine. Some types of chocolate are more dangerous than others. This is why some of you are saying chocolate is an “allergy”. Your dog would need plenty of white chocolate before they showed any symptoms. But chocolate is not an allergy. And even though they can have some, doesn’t mean you should feed them a very little bit of chocolate on the grounds that “its okay for them”. Then it will teach them the smell of chocolate is good, and when they smell dark chocolate or baking chocolate, which are really bad, they will think “Oh! Here’s that really good stuff my owner gave me! I love it! I’m going to scarf this whole pack down and darn the consequences!”

Even if you keep chocolate well out of reach, there will be some time (unless your home is completely chocolate free at all times, in which case i pity you) in which your dog or cat will run across chocolate. Elvoret, your cat would have loads of problems with an 85 percent cocoa bar. Please be sure never to let her have it. Milk chocolate is not as bad as dark chocolate, for the reason that it is the cacao bean that hurts the dog or cat. Please read anon106576 and anon 106414’s comments, they are really good. Chocolate is not an allergy!

Seriously everyone, don’t go and put your pets at risk. It’s like someone saying, “oh, i know all these people who have taken drugs, and they’re fine! It’s just that some people are allergic to drugs.” “Really everyone, i know people who’ve smoked and they’re fine! It’s just an allergy.” Also, carob is awesome for dogs. It tastes kind of like chocolate, but it has no caffeine or theobromine. Carob is also really good for humans too, because it’s healthier, so in the interest of the growing size of the american public, try using it instead of chocolate. Oh, and pumpkin is good for dogs with diarrhea, if you give a teaspoonful with every meal. Carrots and blueberries are good for dogs too, and so is peanut butter. It sounds weird, but dogs can also eat Cheerios. anon106576 August 26, 2010

anon18515: dogs and cats can process fruit and veggies and grains, and in fact fruits and veggies are really really good for them. carrots, apples, blueberries -- they're all really really good for your dog -- even lettuce!

anon53954: turkey is really good for cats and dogs! but they can't eat the skin, because it's too salty. you want to debone it too.

Anon4335: milk chocolate doesn't have as much theobromine in it, but you still don't give it to your dogs! they will get sick and never mind if someone says they won't, don't take chances with your pets, and for heaven's sake, don't listen to people who'll say 'my cat/dog eats chocolate all the time!' would you like your pet to die because you listened to someone on the internet whom you don't even know? anon106414 August 25, 2010

so many people are saying, 'My dog/cat loves chocolate! it's just that some breeds are allergic, you can feed chocolate to the other ones.' There's no such thing as 'allergies' to chocolate. it's poisonous and don't give it to your pets!

jennypenny, popcorn is good for pets. mish999, you are so cruel to your dog. I'm not letting you near charlotte or poppy! i might let you near lily.

i've seen so many people saying 'people food is evil for your pets!' there are some good foods. green beans, carrots, and blueberries are all really good for them. I'm not sure what else. oh yeah, pumpkin's good too. but if you are puzzling over whether to feed a dog food that's not listed as good food, don't give it to them! you never know!

as a general rule, most fruits and veggies are good for them, but i advise you to check. salmon if it's cooked is good for cats! my lily loves salmon, but everyone doesn't allow puss to have any. not fair to pussy cat!

oh yeah, my dog loves blueberries, they're great for puppies. ccreamy August 17, 2010

To all those who think they are wise and who have super pets that are free from proven toxic foods,

keep feeding your pets with these proven toxic food and stop arguing here!

But I am happy to know now what is toxic to my pets.

Remember, your pets suffer! Aby yesterday

You know, I'll bet a lot of people thought the same of smoking. "Geez, I know a lot of people who smoke and live long lives, or seem okay." Grow up. Feed your animals only what is good for them and not what you think is okay just because they like it and it doesn't seem to be hurting them. You don't know! Quit justifying your behavior. Think of your pet.

When the term 'people food' is used, perhaps it is meant 'processed food'. Healthy, fresh people food (that is not toxic to your dog or cat), without spices, salts, etc., are okay.

If your animal is not meant to eat grains because they do not have the enzymes to digest and use the protein from them (like cats), don't feed them stuff with grain in them.

Just because a vet recommends a certain processed pet food doesn't mean it is good for the animal. Do a little research on what type of animal you have and their digestive system. Not research from pet food companies, but from universities and such that are doing unbiased research. Your eyes might just be opened, and your pet a lot better off. anon103037 yesterday

Heed the warning of chocolate but to be damaging, you have to have more than what's usually left around since mostly milk chocolate is left around and it usually takes at least one full bar to harm a medium- to large-sized, adult dog. This is because milk chocolate is mostly milk and only a little bit chocolate so it's barely poisonous unless it is consumed in large quantities. anon99255 July 25, 2010

Please heed the warnings of vets when they say chocolate and other things are poisonous. Would you want to be the one responsible for your pet's death just because you can't hold off giving it these treats? Your pet will be just as happy eating proper treats (carrots and celery for example - my dog loves them). Please don't listen to random people's advice! anon88879 June 7, 2010

My five month old boxer puppy became suddenly ill and i took him to the vet. they are saying he was poisoned with bubble gum! Really? They said it is from xylitol.

He was having seizures and foaming at the mouth and very disoriented. By the time I got him to the vet, 30 minutes away, he was comatose -- unaware of anything. They thought he was dead. He was still breathing but in horrible shape.

They said his liver values had skyrocketed and his sugar was 78. Can this be treated? anon87267 May 29, 2010

Anon 2718: How does your cat get in the fridge? Geez, the simple way to keep pets from getting to "people" food is to not leave it laying around on the counter or table.

If your pet is getting stuff off of the counters you should retrain them not to do that. Never should a cat be allowed near your food while you are preparing it (food prep should be done at the counter not a kitchen table).

Also, Anon 26635, please let me know which brand of wine is yours so I never drink it. Letting a dog run willy nilly through the winery doing its business everywhere during harvest? Eww.

Use your common sense people, if you have any! Allergies and poisoning are two different things! If your pet has poisoning you may not see the signs right away. It can be long term damage that you may not see until it is too late!

The natural/healthy food at the pet stores that contains some of the ingredients listed has probably been treated and is most likely organic since it is in natural/healthy food.

Dogs and cats should never, ever be given human food. Period! All of the chemicals and preservatives and pesticides and such that our food is treated with, their bodies can't handle it. And, if you are giving chocolate, beer or any other poisonous food to your pet on purpose, shame on you!

Chocolates, especially, have been known to be toxic to animals for years! Even the old, country vet that we took our, now deceased, dog Sugar to told us no people food! He didn't have a big list of stuff to avoid, he just said to avoid it all. Also, to keep our dog out of the trash.

If you let your pet eat human food, if you give it to them on purpose or as a "treat", if you let them near food you are preparing, if you don't keep your trash covered or hidden from them then you are irresponsible and shouldn't have pets. Shame on you! anon84574 May 16, 2010

I really don't understand garlic and onions being bad for dogs. I disagree. The reason is most, if not, all store bought dog food contains a little and not only that, but beacon grease is also a ingredient found in most dog food.

Try this: look up homemade dry dog food. Dogs by nature are not fishers, or vegetarians. Take a look at your teeth then your dog's teeth! I hope you see what I'm saying here. Dogs are carnivores a.k.a.. meat eaters, and if you have an active, playful dog, you should make sure at least 10 percent of his or her diet contains animal fat. anon81909 May 3, 2010

if your dog is ever diagnosed with gastro problems be sure they know what they are talking about. my little rat terrier, pickles, has been having problems for two years. every vet that has seen her missed the real problem: her spine. make them x-ray their spine and look for problems there. the spine of course holds the nerves which in turn send signals to the body. under abnormal conditions it sends the wrong signals, affecting their gastrointestinal tract. it may be too late for my pickles. we took her to vet today, she was an older woman we'd never seen before. within one hour she had pickles on intraveneous fluids, sedated, enema to get backed up rotten food out of her, showed us the x-ray and explained to us that this had been the cause of her problems from the start. if only the several vets who had seen her before had caught it she wouldn't be so bad that she couldn't take general anesthesia, her kidneys wouldn't be damaged, her digestive system inflamed, in shock when she arrived, white cell count out of sight, and the pain she was having. she is a bright, intelligent, energetic little dog and other than bowel problems never showed any sign of the seriousness of her condition until today. she wasn't eating, was drinking, and straining to pass stool so hard we thought she would break a bone trying. thank god after two days of this we knew this wasn't like before. she wasn't having a "bout of food allergies" or anything that began with the stomach. vets and human physicians are stupid or careless. i've seen people, including myself, be repeatedly misdiagnosed. i have a voice to get it across to them, give your dog a voice. When they say food allergies, gastrointestinal problems, demand they check the spine. If this would have been caught earlier by a knowledgeable doctor she wouldn't be close to death. her only chance is this very quick and unusually smart doc. I am so mad right now that my little girl has gotten to near death just because no one knew what they were doing. Too many dogs have treatable medical problems, if caught early, and the vet really knows his/her stuff. anon38818 July 28, 2009

To take the guesswork out of this dialog, please refer to the authoritative source below . the AVMA (American Veterinary Medicine Association). It is consistent with this article. Dr. Steven R. Hansen, director of the ASPCA’s Animal Poison Control Center, gives pet owners a full list of foods, plants, chemicals and drugs that are commonly found in people’s homes that can be deadly.

An important aspect of being a good (and responsible) pet owner is to have the discipline *not* to feed (or expose) them to things that taste good but you know can cause them harm. anon37075 July 16, 2009

About the grapes: conventional grapes are one of the most pesticide-riddled crops around, it's more concentrated in raisins, making them our most poisoned produce - tragic irony since that's what many parents try to give their little kids as a healthy snack.

I used to feed my dog organic grapes with no problem. Do you, anon26635, bend over backward to minimize use of chemicals in your vineyards? That would explain it. I'd like to know.

Also, I can corroborate the successful elimination of seizures (in a cat who was having them countless times daily) using Essential Fatty Acids - in our case not just fish oil but a mix of omega oils. Again, the purity is really important, since fats hold toxins. So vegetable oils should be organic & the brand should be one of those that ensures no mercury in their fish oil: Nordic Naturals and Carlsen are probably the most reputable, followed by Spectrum.

I too have sometimes given my dog tiny amounts of garlic therapeutically, and I find none of my holistic health books give very specific info on how much Vit K (I believe that's the culprit, so it's also onions, cabbage, many other otherwise healthy foods) will result in the deadly Heinz anemia. Does anyone know?

Animals don't know when they're being poisoned, any more than people do. And one doesn't know about allergies either until after the fact IF one makes the connection.

Thanks, everyone, it's great to share this very important information. fancyfrenchy April 21, 2009

I think many of the foods discussed may be breed specific. *But* who wants to volunteer their pet? I give my pets garlic and they tend to be more stinky but their blood and coloring (pinkness) stays consistent. They are chihuahuas and french bulldogs. I would say those 2 breeds wouldn't have a problem with garlic.

Also if you do your homework you will find that human grade food (alis: Treats, left overs, etc) are very healthy for your dog. Avoid things you wouldn't eat if you were on a diet or trying to get healthy such as: everything and anything fried, candy, fat, butter/crisco, processed foods, coffee, soda, alcohol. you get it.

First, giving dogs garlic is a great way to keep fleas and ticks off them as they excrete it through the skin.

Chocolate is not harmful as my dogs eat it from time to time without any problem--you'd have to give your dog a *substantial* amount (like, half the animals weight!) of chocolate to kill them.

Please ignore the anonymous commenter who scoffed at the risks of feeding chocolate to dogs. It's not an 'allergy', it's not a matter of building up resistance or immunity.

Chocolate contains theobromine, which is toxic to dogs, cats, horses, and many other animals. They don't metabolize it well, so depending on the size and species of the animal, a small amount could be deadly. (Humans metabolize it very well--that's why it's not a problem for us.)

Google "theobromine toxicity" or "chocolate toxicity" for yourself, if you need more convincing. Don't take a risk with your pet's life because some jackass on the Internet said their pet never had problems. anon25497 January 30, 2009

I always love it when people freak out about how dogs and cats should never be fed anything but meat products because they're carnivores. People like that are generally in the "You're a horrible pet owner, how could you?" self-righteous category.

This is misleading to people. What you fail to realize is that your 'carnivorous' pet--were he living and hunting in the wild--would not be eating steak and bones from the butcher. Wild wolves and cats eat just about *all* of their prey--that includes the stomach and stomach contents. Since they prey largely on herbivores, that means that they *are*--in fact--getting plant matter as part of a normal, healthy diet.

Also, it should be pointed out that your 'carnivorous' canine or feline's wild relatives will not live nearly as long as your pet if you care for him or her properly. Perforated intestines from bone fragments, and death due to prey-borne illness happen in the wild as well. anon23428 December 24, 2008

Re post: "cats and dogs are carnivores"

This is incorrect. Cats are carnivores, but dogs are omnivores.

Dogs and cats are CARNIVORES, they shouldn't be fed any vegetable, fruit, or grain products their digestive systems can't process them.

Toxic salmon? Some fish could be toxic, but more likely parasites in the fish could cause health problems, any raw meat fed to cats or dogs should be frozen first to kill worms and other parasites.

Chicken bones are more a problem for dogs, and no pet should ever be given cooked bones. Also avoid the weight baring bones of large herbivores, like leg bones from cows. Softer raw meaty bones are good for the pet, the bone is an excellent source of calcium, freeze all raw meats for 24+ hours first.

Whenever giving your pet treats, always remember, your pet is a carnivore that's built to hunt, kill, and eat their entire prey. Non-animal products are likely to be unhealthy for them. anon16408 August 5, 2008

An allergic reaction is different than toxicity. If something is toxic to an animal, you may not notice any reaction from them, but over the long-term, it will affect their liver. Kind of like if you drink alcohol, too much over the years will destroy your liver, but in the meantime, you don't notice anything.

Garlic, in small amounts will NOT kill your dog. It's a useful flea/tick/skeeter deterrent. It does the same for cats but there's a higher chance of toxicity - I do 1 week on 2 weeks off for the cats (it can cause a certain type of anemia in cats). anon16043 July 28, 2008

Please do not confuse what a dog or cat likes with what is good for the animal. ANY dog will eat chocolate because it TASTES good. SO DOES ANTI-FREEZE!! But it is NOT good for the animal and can cause serious problems or even death. If you've gotten away with it that only means the animal didn't have enough to be fatal.

Ask yourself if a "little poison" is okay because it won't kill you. Even small amounts of toxic foods are taxing on the animal's system and can lead to an impaired immune system or other problems over time. Err on the side of caution. Stick with healthy foods. There are plenty of them!! anon15689 July 18, 2008

My best friend's beagle LOVES chocolate too and has never gotten sick.

So I think the chocolate allergy depends on the dog and its lifestyle. if your dog has never eaten chocolate and all of a sudden ingests a whole easter bunny, then yah he's going to get very very sick. But if he's built up an immunity to it, then he'll be all right. mish999 May 3, 2008

Why do manufactures of animal products recommend and use garlic for fleas and such when it is toxic to pets?

Also, just wondering about brussel sprouts? My kitten loves them. I do not put any seasonings on them, just a little butter sometimes.

I also have a rather large male cat who loves raisins. Gosh - I hope he has not sustained any long term damage by my giving them to him. Never again. Guess animals are like people, we sometimes crave things that are not good for us! :o)

Also, I keep reading about allergic reactions. Seems to me there is a difference between allergies and toxicity. You do not always know when the liver or kidneys are being damaged until it is too late!

With all the questions you guys have about why your animal isn't showing signs of toxicity when they eat these things, it's quite simple if you compare them to humans, because humans have different allergies, and different tolerance levels. The same is true of other animals, like dogs and cats. Some may be more sensitive to certain food than others, different breeds may be more or less tolerant than others. Greyhounds are a good example of finicky stomachs, they can actually die from eating grapes/raisins, according to the Phoenix Arizona Greyhound Rescue.

Also, if you give two dogs the same amount of chocolate, one being a tiny dog and one being a very large dog, both of which have the same exact tolerance level to theobromine, the smaller dog will have more signs of distress. This is because the concentration of chocolate in the smaller dog is greater, because of the very fact that it is smaller. Think of two glasses of water, one half full, one completely full. Try dissolving the same amount of salt in each. The smaller amount will not be able to dissolve as much salt as the cup that is full, and you will be able to see the salt in the water. Now think of the water as the dog, and the salt as a toxin. Does the fact that the smaller dog is more sensitive to the same amount of chocolate as the large dog mean it is simply more allergic?

Never knew that about grapes. must be part of the reason why my dog has kidney problems now. He used to get them all the time. And I knew that turkey had to have some bad affect on them. He always got real sick after eating it. anon9925 March 16, 2008

The majority of American households make pets part of their family. In 2018, it’s estimated that 68% of households own a pet (more than the percentage with children), which adds up to 84.6 million homes nationally. Perhaps not surprisingly, the most common pets are dogs, which can be found in roughly one out of every two U.S. homes.

Every dog owner knows that while owning a dog can be rewarding, keeping his or her aromatic curiosity in check can be a real challenge. When a dog chews up a new pair of sneakers, it’s annoying, but when he breaks into the pantry, it can be dangerous. In 2017, the ASPCA Animal Poison Control Center received 199,000 poisoning cases, almost one-fifth of which were the result of ingesting human foods.
