20 Foods You Should Never Feed Your Dog

There's a lot of information out there about what you can and cannot feed your dogs... While I'm sure you've heard chocolate is definitely bad for them, there's a bigger list of foods that could be potentially poisonous for your pooch. And because we know you want to be informed about what you cannot feed your little four-legged fur child, we went ahead and did our research and compiled a list of all the foods that could be harmful.



1. Chocolate

let's start with the obvious one first... Chocolate, ESPECIALLY dark chocolate. 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.


2. Alcohol

I'm sure you've seen someone give their dog a sip of beer at a party in college once... And while that pooch might be okay, it's definitely not a good idea. You never know how alcohol will affect your dog and it's really not something to mess around with.


3. Apple Seeds

I bet you didn't know this one! While Apples aren't toxic to dogs, the seeds are. Apple seeds contain a natural chemical (amygdlin) that releases cyanide when digested. You're dog may be fine if they don't chew the seed and swallow them whole, however I wouldn't risk this one either. If you choose to feed your dog an apple, make sure the core and seeds are removed beforehand.


4. Grapes

Since we're talking about fruits, grapes AND raisins are also bad for dogs. It seems this one is a surprise to a lot of people, for example I've heard of people feeding their dogs frozen grapes which terrifies me because even the smallest amount can cause kidney failure for dogs.


5. Avocados

I know some people like to add some fat into their dogs food to keep their coats shiny and help with dandruff, however Avocados and even avocado oil is a big NO. The most dangerous part of an avocado is the pit because it is full of persin which can cause diarrhea, vomiting and heart congestion. Persin can also be found in the good part of the avocado as well so, again, we recommend avoiding feeding it to your dog all together.

6. 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!). So, this should go without saying by now.. But make sure you keep your pup away from any seeds and pits from fruit!


8. Onions, Chives & Garlic

Onions are the absolute worst food you can give your pup, which might come as a surprise to some. They contain disulfides and sulfoxides (thiosulphate), both of which can cause anemia and damage red blood cells. Chopping onions, dropped one on the kitchen floor and your dog ate it right up? A tiny piece shouldn't do much harm but it might be best to keep your dog away from the kitchen when you're chopping onions.


7. Candy, Chewing & Sugar

While sugar may not cause any issues in your pup right after ingesting, too much sugar can lead to dental issues, obesity and even diabetes. In addition, most chewing gums and candies often contain xylitol, which can lead to vomiting, loss of coordination, seizures and liver failure.


8. Toothpaste & Mouthwash

Similar to candies and chewing gum, toothpaste and mouthwash also often contain xylitol. So, while we admire you for your concern about your dogs dental health, make sure you're using a toothpaste made for your pooch such as Arm & Hammer Dog Dental Care Toothpaste or the Pura Naturals Pet Organic Canine Dental Gel. Dental Sticks for your dogs to chew on are always a safe choice!


9. Cat Food

You ran out of dog food and don't feel like running to the store, Cat food should be okay, right? NO! Cat food contains proteins and fats that are targeted at the diet of a cat, which is often too high for your dog.


10. Milk and Dairy Products

Another food often fed to cats that is not good for your dog. Will it's not going to kill your dog, milk and dairy products can cause digestive problems as well as trigger food allergies. Not to mention the smelly farts and diarrhea.


11. Raw Meat & Fish

Your initial thought might be "well, they would be eating raw meat in the wild"... And while that might be true, raw meat and fish can have bacteria which causes food poisoning. So to avoid making your pooch sick, it's best to cook any meat or fish beforehand.


12. Rhubarb & Tomato Leaves

It's best to keep your dogs away from the garden... Rhubard and tomato leaves contain oxalates, which can cause, drooling, vomiting, diarrhea, lethargy, weakness, tremors and bloody urine.

13. Yeast

Just like yeast rises in bread, it will also expand and rise within your pup’s tummy. While if they ingest just a little bit, it may cause gas and discomfort... But too much of it could rupture their stomach and intestines.


14. Vitamins Meant for Humans

Keep your vitamins in the medicine cabinet and away from your dog. Human vitamins often contain 100% of the recommended daily amount of various minerals, which could cause an overdose of a mineral for your dog. The most dangerous vitamin your dog could ingest is prenatal vitamins... So, if you suspect your pet has ingested any vitamins take them to the vet immediately.


15. Macadamia Nuts

Ingesting even a small amount of macadamia nuts can be lethal to your dog. Symptoms include muscle shakes, vomiting, increased temperature and weak back legs.


16. 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.

17. Fat Trimmings

You may think you're giving your dog a nice treat when you feed them your fat trimmings, however cooked and uncooked fat trimmings can cause pancreatitis.


18. Marijuana

We've heard countless stories of dogs getting into people's "brownies" which is extremely scary and should absolutely never happen. Before the high hits, make sure ANY and all marijuana products are safely stored away from your dog. Depending how much your dog was exposed to can affect the level of poison. Common symptoms include slow response times, dribbling urine, heart rate change, neurological stimulation, hyperactivity, coma and even death.

19. Tobacco

Tobacco really isn't good for humans either, but we're not here to judge... Tobacco contains nicotine, which can be lethal to dogs. Symptoms include vomiting, abnormal heart rate, tremors and weakness.

20. Salt

If your dog ingests too much salt it can lead to sodium ion poisoning, which may result in vomiting, diarrhea, depression, tremors, increased temperature, seizures and even death.



If your dog has ingested any of the foods mentioned above and is acting differently in anyway, it is best to seek a veterinarians attention immediately. 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.
