Affenpinscher is a miniature dog breed bred in the middle of the 15th century for the extermination of rodents. Today it is impossible to say with complete certainty which breeds are related to the Affenpinscher. According to one of the assumptions, these were different wire-haired breeds of dwarf pinschers. Affenpinschers are known in the animal world as nimble rat-catchers: the black devil or monkey terrier, as these funny dogs are also called, dexterously and quickly catches rats and strangles them.
