Peanuts aren't toxic to dogs, but a growing number of 'sugar-free', 'no added sugar' and 'keto' nut butters contain xylitol. The FDA warns it can drop a dog's blood sugar dangerously within 10 to 60 minutes. Peanut butter is also calorie-dense, so a spoonful can be a big part of a small dog's daily allowance.

Can Dogs Eat Peanut Butter?

Yes, in moderation
Yes, if it doesn't contain xylitol. Plain, unsalted peanut butter is a popular treat and handy for stuffing toys or hiding pills. Always check the label for xylitol (also called birch sugar), which is very toxic to dogs, and keep portions small because it's high in fat.
This guide is general information, not a diagnosis. If your pet seems unwell, or you're worried, call your vet.
What you need to know
How to offer it safely
- Check every new jar for xylitol or birch sugar.
- Choose unsalted, no-sugar-added peanut butter with just peanuts.
- Use a thin smear in a lick mat or chew toy, or a small amount to hide a pill.
- Count it in your dog's treat calories.
Treats, including human food, should make up no more than about 10% of your dog's daily calories. Our calorie calculator shows your dog's daily needs. Introduce any new food slowly and stop if it causes vomiting or loose stools.
If your dog ate some
- If the peanut butter contained xylitol, call your vet or a poison line immediately.
