The Affenpinscher is a small but sturdy terrier-like dog sporting an intelligent and alert expression. They have a square-type frame and face, round eyes, a short nose, and an undershot jaw that gives rise to its nickname of monkey dog. Theyhave a short, wiry coat with longer wisps over the face and a curly undercoat. The coat comes in a variety of colors including black and tan, black, grey, silver and red. The ears are normally docked, as is the tail by a third of its length, but these can be left natural.
The Affenpinscher (which means “monkey terrier” in German) originated in Europe as a farm dog, flushing rats out of stables and tracking game in the countryside. Over time, Affenpinschers were bred smaller and became popular home companions; however, they still helped keep pesky mice and rats away. Before being registered by the AKC in 1936, the Affenpinscher helped shape several major breeds in Europe, including the Miniature Schnauzer and the Brussels Griffon.
