Originally bred as working dogs:
Though not classified as a terrier, this dog was originally bred to work like one. His job was to exterminate rats and other pests in German stables of the 1600s.
Personality: Standing less than a foot tall, these sturdy terrier-like dogs approach life with great confidence. “This isn’t a breed you train,” a professional dog handler tells us, “He’s like a human. You befriend him.”
They can be willful and domineering, but are mostly loyal, affectionate, and always entertaining.
Appearance:
The dense, harsh coat is described as “neat but shaggy” and comes in several colors; the gait is light and confident.
Influence on two later European breeds:
This dog is thought to have been an influence on the development of such later European breeds such as the Brussels Griffon and the Miniature Schnauzer.
Name of the breed:
Affenpinscher. (The name Affenpinscher is German for “monkey dog” or “ape terrier.”) Eventually, Affenpinschers were brought indoors to rid the kitchen of mice. In time, they became dual-purpose dogs: ratters by day, and by night devoted bed-warming companions for the lady of the house.
Answer: The Affenpinscher is depicted in Auguste Renoir's Impressionist oil painting called "Luncheon of the Boating Party."
