Context paragraphs:
Chizer: The chizer is a mixed dog breed originating in the United States of America.  Chizers are a mix of the Chihuahua and the miniature schnauzer.  This breed is NOT recognized by the American Kennel Club.  The chizer has a combination of looks from both breeds of dogs, and can vary depending upon the breakdown of the breed.  General sizes of a chizer range between 6-14 inches in height and approximately 4-15-lbs in weight.  The chizer is a small breed dog, and works great in smaller areas, such as apartments, condos, and townhomes.  The chizer comes in a typical variety of colours, usually grey, black, brown or white.  This breed has a smooth, short haired coat that needs constant grooming, trimming around the eyes, ears and nose.  They are usually low to average shedding dogs, and typically most groomers leave their facial hair to mimic a schnauzer beard.  The ears of a chizer are medium in length and can stand erect when at attention, and their tail is usually docked.  The chizer can have either an apple shaped head, or round head, with either a long or short snout, giving it either the appearance of a Chihuahua or Miniature Schnauzer.  The body of the chizer is generally long and lean, with slender legs, and a square, robust back end.  This back end tends to make the dog sturdier, and gives them surprising jumping abilities to reach great heights.

German Pinscher: The German Pinscher (original name Deutscher Pinscher, FCI No. 184) is a medium-sized breed of dog, a Pinscher type that originated in Germany.  The breed is included in the origins of the Dobermann, the Rottweiler, the Miniature Pinscher, the Affenpinscher, the Standard Schnauzer (and, by extension, the Miniature Schnauzer and Giant Schnauzer).

Harlequin Pinscher: The Harlequin Pinscher is a type of Miniature Pinscher, which is a toy-sized dog.  It originated in Germany and was 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.

In modern times, it is banned in many nations, but is still legal in a limited number of countries.  Where permitted, it is seen only in certain breeds of dog such as the Pit bull, Miniature Pinscher, Doberman Pinscher, Schnauzer, Great Dane, Boxer, Caucasian Shepherd Dog and Beauceron.
