The Affenpinscher is square-proportioned, compact and sturdy, with medium bone. It is a smaller version of a working terrier, and as such is not a delicate dog. This is an active, tough dog that is agile enough to catch and dispatch rats and mice. Its gait is light, sound and confident. The affenpinscher has a monkeylike facial expression with long eyebrows and beard, which lends it an air of comic seriousness. This breed’s rough coat is about 1 inch long on its body and somewhat longer on its head, neck, chest, stomach and legs. The coat type provided protection from vermin and harsh conditions.

The affenpinscher lives up to its name — “monkey terrier” — in both looks and actions. A terrier at heart, it is busy, inquisitive, bold and stubborn, but it also loves to monkey around, being playful and mischievous. It tends to bark and even climb. Unlike most terriers, it is fairly good with other dogs and pets. This little dog is best with a family that likes entertainment and has a very good sense of humor.
