Can dogs eat
Peanut Butter?
With caution
Only if it contains no xylitol. Plain peanut butter is safe in small amounts, but any product sweetened with xylitol (also called birch sugar) can be life-threatening to dogs.
What to watch out for
Plain peanut butter is not toxic. Most dogs love it, it is rich in protein and fat, and it is handy for filling a lick mat. The problem is the label.
Some peanut butters are sweetened with xylitol, which the FDA says may also be known as birch sugar or wood sugar. In dogs, xylitol causes a potent release of insulin that can drop blood sugar dangerously low within 10 to 60 minutes, and in some cases serious effects may not appear for up to 12 to 24 hours. Xylitol can also cause acute liver failure. Always check the label first for xylitol, birch sugar or wood sugar, every time you buy, since recipes change.
Even safe peanut butter is rich. It is high in natural fat, so too much can lead to obesity and conditions such as pancreatitis. High sodium can also be a problem for dogs, so unsalted peanut butter is a healthier option.
Benefits
- Most dogs find it very motivating, useful for training and enrichment toys
- Provides protein and fat in small amounts
- Easy to spread on lick mats and stuff in toys
Risks
- Xylitol-sweetened products are an emergency for dogs
- High in fat and calories; can lead to obesity and pancreatitis
- Salted versions add sodium
What to give instead
Choose a plain, unsalted peanut butter whose ingredients are just peanuts, and confirm there is no xylitol. Offer a small lick or spread a thin layer on a lick mat or in a puzzle toy.
Treats should not make up more than 10% of your dog's diet, so count peanut butter toward the daily total and keep it occasional. Ask your vet for individual advice, especially if your dog has diabetes, food sensitivities or a history of pancreatitis. Check the label again each time you buy a new jar.

If your dog already ate it
If you think your dog ate peanut butter that contains xylitol, treat it as an emergency even if your dog seems fine. Contact your vet, an emergency clinic, ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 straight away (US; fees may apply). Keep the jar to show the ingredients. Do not make your dog vomit at home. Vomiting usually comes first, followed by signs of low blood sugar such as decreased activity, weakness, staggering, collapse and seizures.
If the peanut butter was xylitol-free and your dog just ate a large amount, expect possible stomach upset and call your vet if it persists or your dog seems unwell.
Frequently asked questions
How do I know if peanut butter has xylitol?
Read the ingredient list for xylitol, birch sugar or wood sugar. If the label is unclear, do not give it.
How much peanut butter can a dog have?
Only small amounts, not every day. It counts toward the 10% treat allowance, and your vet can advise on an amount for your dog.
Why is xylitol so dangerous for dogs?
It causes a rapid release of insulin, which can lead to a sudden, serious drop in blood sugar, and it can also cause liver failure. Contact a vet immediately if your dog may have eaten it.
