The Harlequin Pinscher is a type of Miniature Pinscher, which is a toy-sized dog. It originated in Germany and were created by crossing traditional Miniature Pinschers with various toy-sized short-haired terriers. It originated in Germany where it was used to kill rats and mice. It is known by several different names including the Harlequin Pinscher, Spotted Pinscher, Merle Pinscher, Harlequin Miniature Pinscher and the Harlequin Min Pin. It is believed that the Harlequin Pinscher was created in Germany some time during the late 18th century. They were likely the result of crosses between traditional Miniature Pinschers and Toy Fox Terriers or Rat Terriers. While Harlequin and other Min Pins were mainly used for ratting throughout history, they were also cherished pets. Harlequin Pinschers nearly became extinct following World War II; however, a group of enthusiasts worked together to revive the breed by collecting worthy specimens to breed. Today, although the Harlequin Pinscher is rather rare, select Min Pin breeders are working hard to establish it as a pure-breed that is eligible for registration.
