A List of Foods That Are Toxic for Dogs

Our Carlsbad vets understand that most dog owners live giving their dogs treats every so often. However, some foods that humans love are toxic and potentially deadly for dogs. Here's a handy toxic dog treats and food list you may want to keep on hand.

Why shouldn't I give my dog people food?

Dogs are inquisitive and intelligent animals. Sometimes, their curious nature drives them to get into things they shouldn't. When considering which food to share with your dog, understanding which foods we enjoy are actually toxic to dogs is key. 

A dog's body metabolizes food differently than the way our human bodies do. This is why some things that are relatively harmless to us can cause a veterinary emergency and even prove potentially deadly for dogs.

10 Foods to Never Give Your Dog

Please keep in mind that this deadly dog treats list is just a quick summary of a few of the most common foods that are toxic to dogs. The list is not comprehensive. To learn more about which foods are poisonous or toxic to dogs, contact your vet in Carlsbad.

Cooked Bones

While it may be tempting to give your dog a cooked bone to chew on, they splinter easily and may cause perforation of the gut, which can turn deadly.

Macadamia Nuts

There's a toxin in macadamia nuts which can affect your dog's nervous system and muscles, leading to swollen limbs, panting and weakness.


Xylitol is an artificial sweetener that can cause vomiting, liver failure, seizures, possible hypoglycemia and loss of coordination. In extreme cases, loss of consciousness or even death may occur. 


Tobacco may not be a food, but it's important to have on this list because nicotine is extremely toxic for dogs. Signs of tobacco poisoning in dogs include tremors, weakness, abnormal heart rate and vomiting. 


Avocado leaves, fruit and seeds contain a substance called persin which may cause vomiting and diarrhea in dogs.


Chocolate - and dark chocolate in particular - has a stimulant named theobromine in it that can cause kidney failure in dogs.

Grapes & Raisins

Cakes, cookies or other treats that contain raisins or grapes should be kept out of your dog's reach. Grapes and raisins can cause kidney failure or severe liver damage in dogs.

Corn On The Cob

While corn kernels themselves are not toxic do dogs, a corn cob is on our list of poisonous dog treats for a reason - it can cause a serious blockage in your dog's intestine if swallowed. 


Alcohol can cause intoxication in dogs as it does in people, even in very small amounts. It may also lead to diarrhea, vomiting and in extreme cases, damage to your pooch's central nervous system.

Garlic, Onions & Chives

Garlic, onions, shallots and chives contain substances which may cause anemia and damage red blood cells. The onion family are toxic to dogs whether they are raw or cooked, and signs of illness may take several days to become apparent.
