Foods that are perfectly suitable for human consumption, as well as other animals, may be toxic and even poisonous to your dog, posing a serious threat to their health and well-being. Why? Because all animals have very different rates of metabolism. Metabolism is basically the process of breaking down food and turning it into energy. 

Please note that while we’re attempting to add every food we can find that is potentially unsafe for dogs, there are certain foods that we may miss, so don’t consider a food safe to feed to our dog just because it’s not on this list of foods bad for dogs.

Do your research if you are uncertain and let us know by adding a comment below with your new information, so we can keep this list of food bad for dogs updated. If you are worried about something your pet consumed, please call your vet promptly.

Do not give your dog alcohol on purpose. Alcohol can cause not only intoxication, lack of coordination, poor breathing and abnormal acidity, but potentially even coma and/or death.5

Apple Seeds

The casing of apple seeds are toxic to a dog as they contain a natural chemical (amygdlin) that releases cyanide when digested. This is really only an issue if a large amount was eaten and the seed were chewed up by the dog, causing it to enter its bloodstream. To play it safe, be sure to core and seed apples before you feed them to your dog.2


Avocados contain persin, which can cause diarrhea, vomiting and heart congestion. The most dangerous part of an avocado is the pit because it is a choking hazard and it is full of persin. If you think your dog has ingested an avocado pet, call your vet asap. If your dog ate a small piece of avocado, it will probably be okay, but make sure you monitor your dog and call your vet for further care.5

Candy, Chewing Gum, Toothpaste & Mouthwash

Not only does candy contain sugar, but it often contains xylitol, which can lead to vomiting, loss of coordination, seizures and liver failure.1

Cat Food

Cat food contains proteins and fats that are targeted at the diet of a cat, not a dog. The protein and fat levels in cat food are too high for your dog, and not healthy. Ingesting too much cat food can result in upset stomach, obesity and pancreatitis.3


Chocolate contains theobromine and caffeine, which speed the heart rate and stimulate the nervous system. Depending on the type of chocolate, amount your dog ingested and your dog’s weight will determine how sick (or not sick) your dog may become.

Ingesting too much theobromine and caffeine in chocolate may result in: vomiting, diarrhea, restlessness, increased urination, tremors, elevated heart rate, seizures and death.3 Below is a list of most dangerous to least dangerous chocolate to dogs:

  • Cocoa powder
  • Unsweetened baker’s chocolate
  • Semisweet chocolate
  • Dark chocolate
  • Milk chocolate
  • White chocolate

Since this is a common item in houses and dogs love the smell and taste of it, PetMD created a “dog chocolate toxicity meter” to help you know how serious your dog’s chocolate ingestion may be.

Coffee, Tea & Other Caffeine

Caffeine is extremely dangerous to dog and within 1-2 hours, your dog could be experiencing mild to severe hyperactivity, restlessness, vomiting, elevated heart rate and blood pressure, tremors, seizures and death.4

Cooked Bones

When it comes to bones, the danger is that cooked bones can easily splinter when chewed by your dog. Raw (uncooked) bones, however, are appropriate and good for both your dog’s nutrition and teeth.

Corn On The Cob

While small amounts of corn are safe for a dog to ingest, giving your dog an ear of corn can be dangerous. If your dog is determined enough (which let’s face it, most dogs are) they will eat the cob and all. The cob can be a choking hazard and can cause intestinal blockage. This could be fatal to your dog.3

Fat Trimmings

Cooked and uncooked fat trimmings can cause pancreatitis.5


While garlic can be okay for dogs in very small amounts (and even beneficial for flea treatment), larger amounts can be risky. Garlic is related to onions which is toxic for dogs because it kills dog’s red blood cell count, causing anemia. Signs may include weakness, vomiting and troubles breathing.5

Grapes & Raisins

Grapes and raisins can cause kidney failure for dogs. Even a small amount can make a dog ill. Vomiting is an early symptom followed by depression and low energy. We’ve heard stories of dogs dying from only a handful of grapes, so do not feed your pup this toxic food.5


An ingredient in beer that can be toxic to your dog. The consumption of hops by your dog can cause vomiting, panting, increased heart rate, fever and even death.4

Human Vitamins

It isn’t recommended to give your dog one of your vitamins or supplements. Human vitamins often contain 100% of the recommended daily amount of various minerals. This could cause an overdose of a mineral for your dog.

The most dangerous vitamin is prenatal vitamins, which have a higher dose of iron and can cause iron toxicity in pets. If your dog ingests a bunch of prenatal vitamins (or other vitamins with a high dosage of iron) you should call your vet immediately. 1


In small amounts, liver is great but avoid feeding too much liver to your dog. Liver contains quite a bit of vitamin A, which can adversely affect your pup’s muscles and bones.2

Macadamia Nuts

Ingesting even small amounts of macadamia nuts can be lethal to your dog. Symptoms include muscle shakes, vomiting, increased temperature and weak back legs. If your dog ingested chocolate with the macadamia nuts the symptoms can be worse.5


Depending how much your dog was exposed to can affect the level of poison. There isn’t much information out about dogs and marijuana but from what we can find, these are the common symptoms: slow response times, dribbling urine, heart rate change, neurological stimulation, hyperactivity, coma and even death.4 Read more about Dogs and Marijuana.

Milk & Dairy Products

While small doses aren’t going to kill your dog, you could get some smelly farts and some nasty cases of diarrhea. Milk and dairy products can cause digestive problems as well as trigger food allergies.5

Onions & Chives

No matter what form they’re in (dry, raw, cooked, powder, within other foods), onions are some of the absolute worst foods you could possibly give your pup. They contain disulfides and sulfoxides (thiosulphate), both of which can cause anemia and damage red blood cells.5


Bell Peppers are okay to feed dogs. Dogs are carnivores and prefer meat to vegetables, but there are some benefits to veggies. For example, green peppers are a low-calorie snack that is packed with vitamin C and beta-carotene. Be sure to chop peppers into small pieces because the outer skin can be tough and difficult to chew. Pureeing or steaming the peppers makes them easier to consume and digest. As with most human food, don’t overdo it because too much could lead to sickness. It might go without saying, but never give your dog spicy varieties such as jalapeños or hot peppers!

Persimmon, Peach & Plum Pits

Pits/seeds from these fruits can cause intestinal issues in dogs. Additionally, peach and plum pits have cyanide, which is poisonous to dogs (and people!).5

Raw Meat & Fish

Raw meat and fish can have bacteria which causes food poisoning. Additionally, some fish can contain a parasite that causes “fish disease” or “salmon poisoning disease.” Symptoms include vomiting, fever and enlarged lymph nodes. Cooked fish is perfectly fine since the parasite is killed during the cooking process.5

Rhubarb & Tomato Leaves

These contain oxalates, which can cause, drooling, vomiting, diarrhea, lethargy, weakness, tremors and bloody urine.4


Just like salt isn’t the healthiest thing for humans, it’s even less healthy for dogs. Too much of it can lead to sodium ion poisoning, which may result in vomiting, diarrhea, depression, tremors, increased temperature, seizures and even death.5


This applies to any food containing sugar. Make sure you check the ingredient label for human foods – corn syrup (which is a less expensive form of sugar or glucose) is found in just about everything these days. Too much sugar for your pup can lead to dental issues, obesity and even diabetes.5


Tobacco contains nicotine, which can be lethal to dogs. Symptoms include vomiting, abnormal heart rate, tremors and weakness. Tobacco poisoning can present itself within 1 hour of ingestion.4


A sugar alcohol found in gum, candies, baked goods and other sugar-substituted items, xylitol, while causing no apparent harm to humans, is extremely toxic to dogs. Even small amounts can cause low blood sugar, seizures, liver failure and even death for your pup.5


Just like yeast rises in bread, it will also expand and rise within your pup’s tummy. Make sure they don’t get any. While mild cases will cause gas, lots of farting and discomfort — too much of it could rupture their stomach and intestines. Yeast dough is also dangerous because as it ferments and rises it makes alcohol which can lead to alcohol poisoning.5

Infographic: Foods That Are Toxic For Dogs

Here’s a “menu” of things your dog should never eat.

Foods That Are Toxic For Dogs

To share this infographic on your site, simply copy and paste the code below:

Keep These Foods Out Of Your Dog’s Reach As Well

While these don’t fall in a particular category above, you’ll want to avoid them as well.

Old Food

You don’t like old and moldy food, so what makes you think your dog will? The bacteria in spoiled food contains all sorts of toxins that can be damaging to your dog’s health. Feed them the freshest and best, dog-approved food only!


If you feed your dog leftovers regularly, they won’t get a proper diet. If you do give them table scraps, make sure to take out any bones and trim down the fat.

Human Snacks

Chips can contain garlic and onion powder, cookies may contain raisins, chocolate or macadamia nuts, etc. Bottom line — there’s a reason there’s food and treats made especially for dogs.

Keep Your Dog On A Healthy Diet

Choosing to raise a dog is a big responsibility. Just as with a child, you’ve welcomed another living being into your household and family. We probably don’t have to tell you to take care of your dog, but what people often don’t realize is that as similar as the two can be, they also have very different needs when it comes to food.

Ask your veterinarian what kind of food might be best for your particular dog breed as well as age and any special needs. That way you know what dogs can’t eat and you’re less likely to have any issues.

Safe Human Foods For Dogs

While there are certainly some human foods that are safe to feed your dog there are many which are unsafe and potentially poisonous when ingested by your dog. As a general rule of thumb, it is far better to be safe than sorry, so avoid feeding your dog any human food unless recommended by your vet.

Dogs that are not given human food or table scraps are generally better behaved than dogs who do receive people food. These dogs do not beg because they know they won’t receive any scraps. They also tend to drool less and bother visitors to your home less because they understand that human food is for humans and not for them.

With all this being said, below is a list of human foods that are safe for dogs to eat in moderation.

Lean Meat

Lean meat includes meat without bones that has had excessive fat removed. If feeding chicken and turkey, the skin should also be removed as it can be a source of fat. Lean meat includes the white meat from chicken or turkey and provides a tasty treat for your dog as well as a good source of protein.1


Salmonella and biotin deficiency are two things to be cautious of when feeding your dog raw eggs. Most vets will recommend giving your dog a cooked egg over a raw egg. Eggs are an excellent source of protein and have a host of vitamins for your pup. Don’t worry about cooking the egg in butter, oil, salt, pepper or other additives, your dog doesn’t need those things and they can be harmful to them as well.3


Not including the fruits listed above, dogs can safely enjoy:

  • bananas
  • apple slices
  • strawberries
  • blueberries
  • watermelon
  • cantaloupe
  • cranberries
  • mangoes
  • oranges
  • peaches
  • pears
  • pineapples
  • raspberries

The seeds should be removed from these fruits or in the case of watermelon it should be a seedless melon as most fruit seeds contain a trace amount of arsenic which is poisonous (it’s a small amount but why risk it?).3


The vegetables below are safe for dogs to ingest:

  • broccoli
  • brussels sprouts
  • carrots
  • celery
  • cucumber
  • green beans
  • peas
  • potatoes (only if cooked)
  • spinach
  • sweet potatoes

Vegetables make great low-calorie snacks and good training tools. In fact, you can give your dog slices of carrots as a treat and a healthier alternative to other training treats. Stay away from canned and pickled vegetables as they contain too much salt.3

White Rice

Cooked white rice is frequently referred to as a potential meal for a dog with an upset stomach. Generally boiled white chicken and white rice are used to help firm up stools as well as nourish a dog that is having trouble getting any nutrition from food as a result of illness.5

When In Doubt, Ask A Vet

If your dog is acting strangely, or experiencing even minor symptoms including weakness, lack of coordination, vomiting, diarrhea, etc. and you think they may have consumed something they shouldn’t have, seek a veterinarian’s attention immediately. If you wait too long, your dog might not make it.

What If You Cannot Reach Your Veterinarian?

In an emergency when your veterinarian cannot be reached you should contact your local animal emergency clinic or call the animal poison hotline at 888-232-8870. You can also try the ASPCA Animal Poison Control Center at 888-426-4435.

Depending on the nature of the item ingested the animal poison hotline or your veterinarian may induce vomiting to regurgitate the item that has been ingested. If the item is something that is likely to cause further damage to your dog on the way back up, vomiting will not be induced and other methods of helping your dog will be discussed such as having your dog ingest an item which will bind to the offending food and neutralize it or surgery to remove the item that is causing your dog’s problems.

Be Proactive: Save Yourself From Expensive Vet Bills

If your dog eats something and gets sick, the vet bill can be tough for pet parents to stomach. Take the proactive step and consider pet insurance. That way if an accidental treat becomes a medical emergency, your dog (and your wallet) will be better off. Check out this video we created to better explain what pet insurance is and why it’s worth it.

Portioned properly, raw fish and meat is literally the best diet for dogs if you can afford it. It’s what dogs ate in the wild so naturally it’s what would be best for them. Why didn’t you mention any of this? I don’t think you know enough about dogs to be writing these kinds of articles.
Kimberly Alt (Admin)
Sorry Kyle, we disagree with feeding dogs raw fish and raw meat due to bacteria and parasites that can be found in them. We are not alone in this, as we have sourced Pets WebMD as well. Wild dogs from hundreds/thousands of years ago are very different from the domesticated dogs we have in our homes today.
Any comments on cooked lentils and whole grain rice and oatmeal?
Kimberly Alt (Admin)
Those are all good for dogs in moderation.
Christopher King
Seriously, fish in general? Salmon is one of the main flavours for dog foods, and you see it all the time in the quality grade foods like Acanac, etc..
If you read the section for fish it is talking about raw fish due to a parasite. It states that cooked fish is fine because cooking kills the parasite.
Scott Spiegel
I’d say lime juice/lime too because I didn’t know that and my puppy started coughing bad with an infection
Constance S Avery
Dose anyone know if a dog is constipated could it be because their annal gland needs released?
Ivory Blue
no – anal glad impaction will not cause constipation
It may not cause constipation but it can make it more difficult for them to poop which if they can’t poop they can become constipated, it is kinda confusing but the answer is yes and no.
my sister left her dog with me and he is really hungry. my dad gave him cooked hotdog and he ateabout 6-7 pieces. i looked at the ingredients and it involved garlic powder and salt. im having quite an anxiety attack because im worried he will intoxicated. i just want to know if he will be in any situation?
Ivory Blue
I use hot dogs as training treats – 2 or 3 hot dogs in a day.. never made my dog sick – although I do try to buy dogs that dont have a lot of salt
Manushi Hemathilake
I just recently found out that my dog Molly had gotten out of the house and eaten someone’s cat! That was about 9 months ago, she’s acting very lethargic and refuses to eat anything other than cooked meat. Could the cat meat be poisonous and she’s getting the effects now?
Terri kelley
A lot of recipes mention chicken liver or salmon for dogs is this bad to feed them ?
Susan lee
Salmon is feed to dogs in Alaska. In fact, one type the locals call dog salmon. In Alaska, we need more of certain vitamins in our diet so this might just be a northern necessity as they also have salmon in the northern part of the rest of the world.
Ivory Blue
There is a parasite in raw salmon that will kill your dog if he eats that meat raw. Salmon needs to be cooked before you feed it to your dog. My dog is allergic to Beef, Pork, Lamb, Chicken and Vension… he eats a diet of fish. NewFoundland dogs are fish dogs – highly recommended to raise them on fish… Fish is not bad for your dog… but beware of raw salmon.
Laura McClain
Watermelon rind is toxic
Is people beef jerkey good for your dog he has direar for 3 days
DogsAre Carnivores
Half of this is wrong. My dogs are raw fed to include raw meat fish liver eggs bones. They also get avocados(only part they can’t have is the bark and leafs, proven). Garlic is fine is low amounts and so is black coffee.
As someone who works in an animal hospital, I must advise to NEVER give dogs coffee or other forms of caffeine. I’ve seen it cause heart failure – unnecessary and completely avoidable!!
Ivory Blue
Melanie – curious to know – for those dogs that died of heart failure cause by caffeine – how much caffeine had the dog ingested? and what was the weigh of the dog?… I would guess that if a chihuahua ate 2 pounds of coffee or drank half gallon of coffee or soda – it would have some problems – but so would a 120 pound human if they drank 60 pounds of coffee/soda… just sayin…
Ron Turley
our big poodle grabbed a hot shot ant cartridge, and crunched it. what to look for?
I just thought the Avocado inclusion was interesting…one of the chewable supplements prescribed for my dog by our vet has avacado as one of the main ingredients…although, he doesn’t like them…
Dog owner
I gave my dog mints, is he allowed them?
If they are DOG mints, then probably
Cam Wagar
Anyone who has an actual clue or does at least somewhat in-depth research will know a lot of this pertaining high protein foods is complete crap. Sure salmonella can “arise” but highly doubtful, where do you all think dogs derived from??? Wild beasts, that had nothing but wild to live off of. Which includes raw anything, of course to pursue full raw benefits and prevent dogs from getting sick in anyway the diet should be weened in. 95% of kibble is pure trash and has no benefits. All the actual benefits are destroyed once they bake it at an ungodly degree. The ENTIRE raw egg including the shell (preferably not store bought because of an insane amount of chemicals used) and RED meat or raw fish (primarily salmon or cod) are much more beneficial for dogs, and honestly feeding your dog chicken of any kind besides chicken eggs is probably one of the worst ideas. Cheap, terrible meat and that has very little benefit for a dog. Also most dogs have an allergy to this, especially shepherd breeds. Red meats are high in protein, myoglobin, and several vitamins and, as with most raw foods, is highly beneficial to dental health and digestive health. Not to mention dogs love it. Also liver, hearts, and gullets are extremely beneficial as well. Fish obviously very high in omega 3’s & 6’s. Most raw items are amazing for your dogs skin health most of all. With added supplementation such as bone broth, and proper fruits and veg, along with digestive aids (i.e. tumeric, goats milk, etc.) all of these items will make your dog thrive. And since when is marijuana a food ?? That one gave me a chuckle.
People use the marijuana in cookies and brownies..
Frank Stiles
Feeding raw proteins to your pets is just asking for an eventual case of E Coli or Salmonella. If these proteins are so nutritious raw, I suggest you eat them as well as feed them to your pet. I suggest you start with raw chicken first.

Can someone please tell me what I can give my shitsue mix cause I really don’t have anything else But her in my life… Please help me

You should contact your vet immediately in instances like this. If you think your dog has ingested something they shouldn’t have, your dog may need immediate medical attention. Comments on our site can be in moderation for up to 72 hours since we do not moderate on weekends. I hope your dog is doing well and got the care she needed!

Go ! Go!!! to the nearest vet hospital. NOW !! She is in toxic shock, and can die. So what, you don’t have $$. If you love her, you WILL find it.
Very helpful
It seems the writer of this post does not know the meaning of the word toxic.
Thank you for the artical.
question to those more knowledgeable. Today I put my dog down (he had a large mass and internal bleeding. Doctor said it was most likely cancer) We chose not to pursue to prolonging his life as he was old and didn’t deserve the pain just to live a few more months with us. (according to doctor) any way I was too ashamed to ask the doctor this but we had a puppy come to us and old dog starting eating the poop so I put sriracha on it once, dog thought it was even tastier so I put a hot spice. thinking it was cayenne or habanaro, not sure which I grabbed an He loved that too. Did I kill my dog by feeding him spice, would a mass grow that fast from what I did or could I have ruptured it. This was three weeks ago and I only did it twice, three time maybe but he loved it so much I stopped.
No you did not.
All the spice in the things that you put on the puppy poop could have given the older dog upset stomach, maybe gas, and maybe diarrhea but that’s about it. Guarantee that you did not cause the mass or the bleeding. You shouldn’t be afraid to talk honestly with your vet. They are doctors and are the best source a reliable information, just like people doctors. So very sorry for your loss.

Thanks for your good and useful article. your website gives practical information.
My dog ate a pound chocolate bar left out in the living room. Wrapper and all. Next morning, after a long night with the vet -she died in my arms. She died because of my own ignorance and shortcoming in not keeping that chocolate out of her reach. I realize a pound is quite a bit for someone to intentionally (or unintentionally) give their dog at one time or within a short amount of time. My current and future dogs will never taste even a lick of chocolate. I don’t believe the articles we read on the internet are meant to be all inclusive or all knowing. If one is searching for answers, much more research is needed than relying on one site to provide you with all the answers. This article gives one a detailed list (from a compilation of sources) of foods to give or not to give to dogs – merely as a stepping stone in your own quest for answers. From here, use some common sense and further research those that you may agree or disagree with. Keeping in mind that all dogs are different which this writer has stated. Your dog may very well be able to tolerate foods that are on the don’t give to dogs list. Your dog may be an exception, not the rule. This may be the reason behind all the sarcastic comments people are making as to why this writer doesn’t appear to know what she’s talking about. I believe this article to be educational and enlightening. A stepping stone as it was meant to be – in my continuing research as to what to keep out of the reach of my dogs.
Kimberly Alt (Admin)
I am so sorry for your loss Deb. Please know that my thoughts are with you during this time. And thank you for your kind words.
Thank you for sharing your very painful experience with all of us. It helps to remind us that our fur babies can get into things without us giving them to them. They will eat things in their environment not just what we feed them, so we need to be vigilant about our dog’s environment. I’m very sorry about your loss.
