Can dogs eat walnuts?

Whether your dog just nabbed your slice of banana-walnut bread or they're chewing on the walnuts off your tree, it's time to break that nutty habit.

One reason why walnuts are unsafe for dogs is due to their high fat content. Dogs have difficulty digesting large amounts of fat, which can lead to gastrointestinal problems like diarrhea and vomiting. Over time, too much fat can increase your dog's risk of developing pancreatitis.

Another concern with feeding your dog walnuts is the possibility of choking or intestinal blockages. Walnut shells are hard and difficult to digest! Whether your dog eats them whole or just in large pieces, they could get stuck in their digestive tract and contribute to serious health issues like an intestinal block. (No fun!)

If your dog requires veterinary treatment due to eating walnuts (or any other unsafe food), pet insurance can help cover the cost of treatment.

Can cats eat walnuts?

Cats don't generally go nuts for walnuts...but if yours does, can they have any?

In short, nope.

Walnuts contain quite a bit of fat, which may give your cat gastrointestinal issues such as vomiting or diarrhea and possibly even pancreatitis. Not fun for your cat (or you!).

Another reason why feeding walnuts to cats is unsafe?

Walnut shells and walnuts themselves can be choking hazards. Cats have small mouths and don't chew their food fully before swallowing, which increases the likelihood of walnut pieces getting stuck in their throat. Yikes.

If your cat requires veterinary treatment due to eating walnuts (or any other unsafe food), pet insurance can help cover the cost of treatment.
