The following small beans for you to introduce the purebred miniature Doberman identification method.　　The purebred miniature Doberman identification method: upright ears, high ear position, can cut ears. Eyes are full, bright, dark or pure black, slightly ovoid, with dark circles, except for chocolate colored dogs (eye color is consistent with body color). The nosepiece is black, except for chocolate colored dogs (consistent with body color). The muzzle is strong but not slender, forming a whole with the head, and the teeth bite in a clipped shape. The neck is slightly arched and elegantly curved, with well-developed muscles and no flab. The chest is well developed and moderately deep. The backline is horizontal or slightly backward. The front legs and hindquarters move parallel to each other, neither bending inward nor outward. The tail is erect, with a high tail heel, truncated at the appropriate position. The coat is short, smooth and glossy, and is close to the body. A dark brown coat is typical of the Miniature Doberman. The lips, cheeks, chest, jaws, throat, front feet, hind feet, heels and around the underside of the tail are all fawn. The better breeds are those that do not have white hair on the chest.

The front legs are elevated and lightly lowered, the ankles are bent, free and easy to move, and the hindquarters are well driven. The Miniature Doberman is a native German breed, also known as the Deer Dog because of its deer-like form. It has been featured in many recent paintings and is now popular in Europe and the United States. It has been around for centuries, and its ancestor is the German Doberman Pinscher. The German Doberman Pinscher has a mix of Italian Greyhound and Dachshund genes in its bloodline. Centuries before the Miniature Doberman was created, the Miniature Doberman (German for Terrier) was already present in Germany and Scandinavia. The breed was officially recognized in 1870 and became widespread in Europe. 1895 saw the establishment of the German Doberman Club and the recognition of the Miniature Doberman. 1920 saw the introduction of the Miniature Doberman to the United States, where it became very popular. 1929 saw the establishment of the American Miniature Doberman Club, and the breed flourished in the United States more than in England.
