Can Dogs and Cats Eat Peanut Butter?

Dogs
SafePlain peanut butter is generally safe for dogs in moderation and is a popular treat — just confirm the label doesn't contain xylitol, which is increasingly used in reduced-sugar versions.
Cats
Safe in ModerationMildPeanut butter isn't toxic to cats, but its high fat content and sticky texture make it a poor treat choice for them.
What makes peanut butter safe — and when it isn't
Peanut butter itself is not toxic to dogs or cats. The concerns are what gets added to it and how much is eaten. Xylitol, which appears in some "sugar-free" or "reduced sugar" brands, is highly dangerous to dogs. Salt, sugar and palm oil add calories without benefit.
How much is too much?
Peanut butter is rich in fat and calories. A common veterinary guideline is that treats should make up no more than about 10 percent of a pet's daily calories, so a thin smear on a toy is plenty, not spoonfuls. Too much can cause stomach upset or contribute to weight gain and pancreatitis in susceptible dogs.
For cats, it is sticky and can be awkward to swallow, and it offers little they need.
Signs to watch for
- Vomiting or diarrhea after a large amount
- Abdominal discomfort
- Signs of low blood sugar if the product contained xylitol (see our xylitol page)
If the label lists xylitol and your pet ate any, treat it as an emergency.
What to do
Read the ingredient list before you give any. If xylitol (or "birch sugar") appears and your dog ate some, call your vet or poison control immediately.
Safer alternatives
A small amount of plain peanut butter works well smeared in a puzzle toy, on a lick mat, or to hide a pill.
Frequently asked questions
Can puppies have peanut butter?
Small amounts of plain, xylitol-free peanut butter are commonly used in training, but check with your vet for very young puppies.
Is crunchy peanut butter okay?
Texture is not usually the problem for dogs. The label is: check for xylitol, added sugar and excess salt whether it is smooth or crunchy.
