Can Dogs Eat Peanuts?
Peanuts themselves are fine in small amounts. Xylitol, a sweetener in some peanut butters, can be deadly.
Yes, dogs can eat peanuts, as long as they are plain, unsalted and out of the shell. Peanuts are a good source of protein and healthy fats, which makes them a fine occasional treat. The real danger is not the nut but xylitol, a sweetener hidden in some peanut butters that is toxic to dogs, so always read the label. Given plain, they sit alongside other dog-safe treats such as a slice of banana.

Frequently Asked Questions
Can dogs eat peanut butter?
Yes, most dogs can eat plain peanut butter in small amounts, and many love it. The one thing you must check is the ingredient list: if it contains xylitol, also labelled as birch sugar, do not give it to your dog. Choose an unsalted, unsweetened, xylitol-free peanut butter.
Why is xylitol so dangerous for dogs?
Xylitol is a sugar substitute found in some peanut butters, sugar-free gum and baked goods. In dogs it causes a rapid, dangerous drop in blood sugar and can lead to liver failure, even in tiny amounts. It is a medical emergency, so call your vet or a pet poison line at once.
Can dogs eat salted peanuts?
It is best to avoid them. Too much salt is bad for dogs and can cause increased thirst, and in large amounts, sodium poisoning. Flavored, honey-roasted and coated peanuts add sugar and seasonings that dogs do not need. Stick to plain, unsalted, shelled peanuts.
Are peanut shells safe for dogs?
No. Peanut shells are rough and fibrous, hard to digest, and can cause choking or an intestinal blockage, and they may irritate the gut. Always remove the shell and give only the nut itself.
How many peanuts can a dog have?
Only a few. Peanuts are high in fat, so a small dog should have just one or two and a large dog no more than a small handful, as an occasional treat. Too much fat can lead to an upset stomach, weight gain or pancreatitis over time.
Can dogs be allergic to peanuts?
It is uncommon, but possible. Peanut allergies are far rarer in dogs than in people. Introduce peanuts in a tiny amount the first time and watch for itching, swelling, hives, vomiting or diarrhea. If you see any reaction, stop and contact your vet.
