Can dogs eat peanuts?

Caution — plain unsalted only

Plain unsalted peanuts are safe for most dogs in small amounts. Avoid salted, flavoured, or honey-roasted peanuts, and always remove shells.

The full picture

Peanuts are legumes, not nuts, and unlike macadamias they aren't toxic. Plain, shelled, unsalted peanuts make a reasonable occasional treat. Problems: salt in salted peanuts, onion/garlic seasoning in flavoured ones, and high fat — pancreatitis is a real risk for sensitive dogs. Shells are a choking hazard. Honey-roasted and dry-roasted usually have sugar and seasonings. Peanut butter is safer but always check for xylitol.

  • High fat can trigger pancreatitis
  • Salt in salted varieties
