The Affenpinscher is one of the most ancient of Toy dogs.
In German, Affenpinscher means "Monkey Terrier."
"Terrier-type" with a "monkey face", Affenpinschers are the bred-down versions of terriers designed to keep rodent populations to a minimum on stables and farms.
The Affenpinscher is believed to have been a major influence in the development of many of the smaller rough-coated breeds of continental Europe, including the Brussels Griffon and the Miniature Schnauzer.
The Affenpinscher was admitted to the AKC Stud Book in 1936.
The area around Munich, Germany, eventually became the heart of Affenpinscher breeding.
