Is it safe and healthy to feed my dog peanut butter?

Q&A with Dr. Erika Sullivan, Because Animal’s Chief Veterinary Officer.

Most dogs love peanut butter and PB is in many dog treats, but is it actually healthy?

I recommend it all the time.

Dogs resemble us in terms of digestion and constitution. We are both omnivores that have digestive enzymes that make it very capable for us to live well on a plant-based diet, but we also have enzymes to break down meat.

We so often relate dogs to wolves, but it’s been proven that dogs’ digestive enzymes are quite different from wolves having been domesticated for tens of thousands of years. Dogs have adapted to having digestive enzymes that break down more carbohydrates and plant-based proteins.

All of which is to say, peanuts are completely fine for dogs. In fact, I probably recommend them every day from both a nutritional and a behavioural sense.

Peanut butter is a great addition to dog treats - to make healthy, fatty, high protein treats that also taste good. Peanut butter treats appeal to dogs the same way they do to us - they smell good when they’re baked, and they are a source of fat and protein. In fact, dogs and cats require higher amounts of fat in their diet than humans do, making peanut butter and other foods high in healthy fats all the more important for our pets.

But, unlike humans, we don’t see peanut allergies in dogs. So many people feed their dogs peanut butter and I’ve never, in 15 years of practice, seen a dog have an allergic reaction from peanut butter. There are however some nuts we do see problems with such as macadamia nuts.

I often recommend that people put peanut butter in “Kong” toys, those rubber beehive-shaped toys dogs can chew on that are indestructible. Smear a bit of peanut butter in the hollow center and you have a great way to keep your dog chewing on something they can’t destroy or swallow and that will keep them distracted and amused.
