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.

Does size or breed matter?
Peanuts aren't classed as toxic to dogs the way macadamia nuts are, but they're a choking and obstruction risk (particularly whole or in shell) and high in fat, which matters more for small and toy breeds and any dog prone to pancreatitis. Always give plain, unsalted, shelled nuts in small amounts, chopped for smaller dogs.
