Can Dogs Eat Peanut Butter? Xylitol and Portions

Yes, dogs can eat peanut butter — as long as it's plain, ideally unsalted, and contains no xylitol. In small amounts it's a safe treat that most dogs adore. The single most important step is checking the label, because some peanut and nut butters are sweetened with xylitol, which is poisonous to dogs.

Why dogs love peanut butter

Peanut butter is rich, sticky and strongly scented, which makes it one of the most useful tools for dog owners. It contains:

• Protein and healthy fats.
• Vitamins B and E and niacin.

But it's also very high in fat and calories, so it's a treat, not a source of nutrition. A complete dog food already covers your dog's needs.

The risks

Xylitol

This is the big one. Dogs release a surge of insulin when they eat xylitol, and their blood sugar can fall within 10 to 60 minutes. Early signs include vomiting, weakness, wobbling, collapse and seizures. Liver damage may follow over the next day or so. Xylitol also turns up in sugar-free gum, mints, sweets, some baked goods, toothpaste and chewable vitamins — see our list of foods that are toxic to dogs.

Fat and calories

One tablespoon of peanut butter contains roughly 90–100 calories. For a small dog, that can be a large part of their daily allowance. Too much can lead to weight gain, and very fatty foods can trigger tummy upsets or pancreatitis in dogs who are prone to it.

Salt, sugar and additives

Many supermarket peanut butters contain added salt, sugar and oils. Choose one with as few ingredients as possible — ideally just peanuts. Avoid chocolate spreads, flavoured nut butters and peanut snacks such as salted or coated peanuts.

Allergies

Peanut allergies are uncommon in dogs, but they can happen. Signs include itching, red skin, ear problems, vomiting or diarrhoea.

Clever ways to use peanut butter

• Stuffed chew toys: smear a thin layer inside a hollow rubber toy such as a Kong, then freeze it. It's a great way to keep a dog busy during crate time — see our guide to crate training a puppy.
• Lick mats: spread a thin layer to help a dog settle during bathing, nail trims or grooming.
• Hiding tablets: some owners use a dab to help dogs take a tablet your vet has prescribed. Check with your vet that this suits the medicine.
• Mixing with other foods: combine a little peanut butter with plain mashed banana or plain yoghurt to make it go further.

How much peanut butter can a dog eat?

Treats should stay under about 10% of your dog's daily calories. As a rough guide for plain, xylitol-free peanut butter:

Ask your vet before giving peanut butter to a dog who is overweight, has diabetes, or has had pancreatitis.

Can puppies eat peanut butter?

Yes, in tiny amounts. A small lick of plain, xylitol-free peanut butter is fine for most puppies, and a thin smear in a frozen chew toy can be soothing during teething. Introduce it on its own and keep the amount small, since puppies need their full meals of complete puppy food to grow well.

Alternatives

If you'd rather skip peanut butter, plain mashed pumpkin (not pie filling), mashed banana or plain unsweetened yoghurt work well in chew toys and on lick mats — again in small amounts.
