The Affenpinscher is a very small kind of dog, weighing between 3kg and 6kg (6lbs to 13lbs) and standing between 23cm and 30cm (9 and 12 inches) at the shoulder. Their face is flat and "monkey-like." The most common and preferred colour of fur for this breed is black, but they can also come in grey, beige, and other colours. In the American Kennel Club, a good example of these dogs could be any colour; in the French and British Kennel Clubs they must only be black.
