Can dogs eat peanuts?
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.
If your dog ate more than a safe amount
If your dog has eaten salted or flavoured peanuts, watch for digestive upset from the salt and fat. Watch for signs of allergy on first exposure. Check any peanut product for xylitol.
