Peanut butter is generally fine for dogs to eat as long as they do not have peanut allergies. Peanut butter is a good treat to give to dogs because it provides an additional source of protein and healthy fats.
While natural, smooth peanut butter is safe for dogs, it is best to avoid giving dogs crunchy peanut butter or peanut butter with added salt and sugar. Crunchy peanut butter can cause certain dogs to choke while added salt and sugar is bad for their diet. Dogs typically do not have peanut allergies. However, dogs can develop peanut allergies over time.
