Can Dogs Eat Peanut Butter? Yes, If It Has No Xylitol

Why plain peanut butter is safe for dogs

Peanuts are legumes, and plain peanut butter is ground peanuts with a little salt and sometimes oil or sugar. None of those are toxic to dogs in treat-sized amounts. The AKC says peanut butter is fine in moderation, and most dogs find it irresistible, which is why it is a favorite filler for food puzzles.

It is also very calorie-dense. A level tablespoon is around 90 to 100 calories, which is a third of a 10 lb dog's daily needs. That, not toxicity, is why plain peanut butter needs portion control.

The xylitol warning

Xylitol is a sugar substitute found in some sugar-free and reduced-sugar peanut butters and nut butters, as well as gum, candy and baked goods. The AKC says it can cause dangerously low blood sugar in dogs, and Pet Poison Helpline warns this can begin within 10 to 15 minutes; larger amounts can cause acute liver failure.

Read the ingredient list on every jar, including brands you have bought before, because recipes change. Look for xylitol, birch sugar or sugar alcohols. Most standard grocery peanut butters do not contain it, but specialty, keto and protein spreads are where it tends to turn up.

Choosing a jar for your dog

The AKC recommends unsalted peanut butter, a peanut butter made for dogs, or homemade, because high sodium is not good for dogs. The best label reads peanuts and nothing else, or peanuts and a little salt. Creamy and crunchy are both fine for medium and large dogs.

Avoid chocolate peanut butter spreads, honey-roasted or flavored versions, and peanut butter cups and cookies, which may add chocolate, sugar or xylitol. Peanut butter crackers and sandwiches add salt and bread that a dog does not need.

How much peanut butter by dog weight

Follow the 10 percent rule the AKC suggests: treats make up no more than 10 percent of the daily diet. In practice for healthy adult dogs: under 20 lb, half a teaspoon; 20–50 lb, one teaspoon; over 50 lb, up to a tablespoon. That is per day at most, not per training session.

Spread it thinly on a lick mat or inside a rubber toy and freeze it, and that small amount lasts much longer. Cut back the dog's regular food on days you use more, and skip it for dogs who are overweight.

If you like to share small snacks, a lick mat or a treat ball makes a little go further and slows a fast eater down.

Puppies and dogs with health conditions

Puppies can have a tiny smear of plain, xylitol-free peanut butter once they are on solid food, and a thin layer in a chew toy can help with teething boredom. Keep amounts very small; a puppy's daily calories are better spent on complete puppy food.

The AKC advises asking your vet first if your dog has diabetes or food sensitivities. Dogs with a history of pancreatitis or on a low-fat diet should usually avoid it, because peanut butter is roughly half fat. Peanut allergies are uncommon in dogs, but itching or stomach upset after eating it is worth mentioning to your vet.

Signs of trouble, and when to call a vet

After a xylitol exposure, signs can start within an hour: vomiting, weakness, wobbliness, trembling, collapse or seizures. Go to a vet or emergency clinic right away, even if your dog seems fine at first, because liver damage can follow one to three days later.

After a big helping of plain peanut butter, for example a dog that raided an open jar, watch for vomiting, diarrhea or a sore belly over the next day. Call your vet if your dog is hunched, repeatedly vomiting, very tired or refusing food, since a large fatty meal can trigger more serious stomach trouble.

Safe ways to use peanut butter, and alternatives

Use a dab to hide a pill only if your vet confirms the medicine can be given with food, and to fill a puzzle toy for a dog left home alone. For a lower-calorie alternative, try plain canned pumpkin or plain nonfat Greek yogurt spread thinly on a lick mat.
