Height: Both male and female papillon dogs reach 8 to 11 inches in height when fully grown, which is about the same size as a Yorkshire terrier. Weight: An adult papillon won't normally weigh more than 10 pounds. Coat: The topcoat of a Papillon dog is silky, soft and flowing. They don't have undercoats. They range from lemon or white to red, rich mahogany or chestnut in color. It's not uncommon for a light-colored Papillon to have patches of darker fur.
