Known as the "King of the Toys," the Miniature Pinscher is a compact, smooth-coated dog who is alert, spirited and fearless, with a unique high-stepping, hackney-like gait. With his black and rust coloring, cropped ears, and docked tail, he resembles his cousin the Doberman Pinscher, but he is not a miniature Dobie.       "Pinscher" means "Terrier" in German, and the Miniature Pinscher is a distinctly German breed that originated several centuries ago as an efficient barnyard ratter. The Miniature Pinscher is reported to include the Dachshund and Italian Greyhound among its ancestors, along with the shorthaired German Pinscher.
