The Affenpinscher, often referred to as the “Monkey Terrier,” is a small breed with a sturdy build, characterized by its distinctive facial expression that resembles that of a monkey. With origins tracing back to Germany, this breed was initially used to catch rats and mice in homes, stables, and shops. Affenpinschers have a dense, rough coat that comes in various colors, including black, gray, silver, red, and tan. Their small size, typically weighing between 7 to 10 pounds, makes them ideal for apartment living.
