Why
Peanut butter provides protein and healthy fats, and many dogs love it in puzzle toys or to help take a pill. Peanuts themselves are not toxic to dogs.
The danger is xylitol, a sugar substitute added to some reduced-sugar or "natural" nut butters, sometimes listed as birch sugar. Xylitol can be deadly for dogs. Peanut butter is also high in calories, so large amounts can lead to weight gain.
Risks to watch for
- Xylitol or birch sugar in the ingredient list: do not use
- High salt or added sugar
- Weight gain with frequent use
- Rarely, peanut allergy: itching, swelling or hives
How to share safely
- Read the label every time you buy a new brand. The ingredients should ideally be just peanuts, and perhaps salt.
- Spread a thin layer in a lick mat or stuff it into a toy.
- Keep chunky varieties away from very small dogs who gulp food.
How much?
About half a teaspoon for small dogs and up to a tablespoon for large dogs, not every day.
