Toxic Dog Food List

Loving dog owners enjoy giving their canine friends special treats now and again, but it is important to remember that some human foods are toxic to dogs. In today's post, our Monroe vets share some foods and treats that are toxic to dogs.

Foods You Should Never Give to a 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 Monroe vet.

If you find your dog has consumed one of the foods below, contact a vet right away as it could constitute a veterinary emergency!

Garlic, Onions & Chives

Garlic, onions, shallots, and chives contain substances that can potentially harm red blood cells and cause anemia in dogs. It's important to be aware that the onion family is toxic to dogs, whether they are raw or cooked.

Signs of illness may not appear immediately and could take several days to become apparent. Therefore, it's essential to closely monitor your onions while cooking in the presence of your dogs.


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

Grapes and raisins can potentially lead to serious liver damage or kidney failure in dogs. It is crucial to avoid leaving grapes or any treats containing grapes or raisins within reach of your dogs. Your pooch will greatly appreciate your carefulness in ensuring their safety.


A sweet snack for people, chocolate is not such a sweet time for dogs. Chocolate contains a stimulant called theobromine which can cause kidney failure in dogs.  Dark chocolate is particularly rich in 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 all 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.


The artificial sweetener known as Xylitol can cause vomiting, coordination problems, seizures, liver failure, and potentially low blood sugar levels leading to unconsciousness or even death in severe cases.

Certain dog treats, like peanut butter, may contain Xylitol depending on the brand. Therefore, it is crucial to check the nutrition label before giving any food to your dog.

Macadamia Nuts

Macadamia nuts contain a toxin 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 persin which may cause vomiting and diarrhea in dogs.

Cooked Bones

It might seem counter-intuitive, but you've likely always been told that all a good dog wants is a bone to chew on, but giving your pup cooked bones is a recipe for disaster.

Cooked bones splinter easily and often lead to a perforation of the gut when given to dogs, an injury that is liable to prove fatal.
