Toxic Dogs Food & Treat List

Our La Pine vets understand that loving dog owners like to give their canine friends treats from time to time. However, it's important to know that not all treats are safe for dogs. Surprisingly, many human foods are toxic to dogs! In today's post, La Pine Animal Hospital will discuss the list of toxic dog treats you need to avoid.

10 Foods You Should Never Give Your Dog

Please note that this list is just a summary of some of the most common foods that are toxic to dogs. It is not a comprehensive list. To find out more about which foods are toxic or poisonous to dogs, speak to your La Pine vet.

Garlic, Onions & Chives

Garlic, onions, shallots, and chives contain substances that can cause anemia and damage red blood cells. The onion family is toxic to dogs, whether raw or cooked. Signs of illness may take several days to appear, so it's important to watch your dogs closely when cooking around them.


Alcohol can cause intoxication in dogs. An incredibly small amount of alcohol is all it takes to cause vomiting, diarrhea, and, in extreme cases, damage to your dog's central nervous system.

Grapes & Raisins

Remember that grapes and raisins can cause severe liver damage or even kidney failure in dogs. Therefore, it's important to avoid leaving any grapes or treats containing grapes or raisins within reach of your canine companion. Your furry friend will greatly appreciate your diligence.


Although chocolate is a potentially delightful treat for humans, it can be harmful to dogs. It contains theobromine, a stimulant that can lead to kidney failure in dogs, with dark chocolate having particularly high levels of theobromine.

Corn On The Cob

While corn kernels themselves are not toxic to dogs, should they swallow the cob, it may cause a serious blockage in your dog’s intestine.


You may be wondering, wait, tobacco isn't food? And you'd be right. We know it isn't food, but your friendly dog does not! Tobacco is devastatingly toxic to dogs, so it is critical not to leave any within their reach. Symptoms of tobacco poisoning in dogs include vomiting, abnormal heart rate, tremors, and weakness.


Xylitol, an artificial sweetener, can cause vomiting, loss of coordination, seizures, liver failure, and possibly hypoglycemia in dogs, which can lead to loss of consciousness or even death in extreme cases. Some foods commonly given as dog treats, such as peanut butter, may contain Xylitol depending on the brand, so it is important to check the nutrition label before giving anything to your dog.

Macadamia Nuts

Macadamia nuts contain toxins that can affect your dog’s muscles and nervous system, resulting in weakness, swollen limbs, and panting.


Avocados not only single-handedly lead to millennials destroying the economy, but they are also highly toxic to dogs. Avocado leaves, fruit, and seeds contain a substance called person, which may cause vomiting and diarrhea in dogs.

Cooked Bones

You've probably been told that a good dog only wants a bone to chew on. However, giving your pup cooked bones is dangerous. Cooked bones splinter easily and can perforate the gut, which is often fatal for dogs.
