Can Dogs Eat Peanut Butter? Safe Brands & Xylitol Warning
Most peanut butter is perfectly safe for dogs and makes an excellent treat. But one ingredient, xylitol, can turn this beloved snack into a deadly poison. Here is how to choose safely.
Plain peanut butter without xylitol (birch sugar) is safe and nutritious for dogs in moderation. Always check the label before sharing.
The Xylitol Danger
Xylitol (also labeled as "birch sugar" or "birch xylitol") is an artificial sweetener that is extremely toxic to dogs. Even small amounts can cause a rapid, life-threatening drop in blood sugar (hypoglycemia) and liver failure.
While xylitol in peanut butter is relatively uncommon, several brands have added it as a low-calorie sweetener. Always read the ingredient list before giving any peanut butter to your dog.
Brands to Avoid (May Contain Xylitol)
Some peanut butter and nut butter brands that have used xylitol include Nuts 'N More, Krush Nutrition, and certain "sugar-free" or "keto" labeled nut butters. Always check the label, as formulations change.
What to Look for on the Label
The safest peanut butter for dogs has just one or two ingredients:
- Ideal: Peanuts only (no salt, no sugar, no additives)
- Acceptable: Peanuts and salt
- Avoid: Any peanut butter containing xylitol, birch sugar, or excessive added sugars
Portion Guide by Dog Size
Peanut butter is calorie-dense (about 95 calories per tablespoon), so moderation is key. Treats should make up no more than 10% of your dog's daily caloric intake.
| Dog Size | Weight | Max Peanut Butter / Day |
|---|---|---|
| Small | Under 20 lbs | 1/2 tablespoon |
| Medium | 20-50 lbs | 1 tablespoon |
| Large | Over 50 lbs | 1-2 tablespoons |
