The Doberman Pinscher was developed in Germany during the late 19th century, primarily as a guard dog. Its exact ancestry is unknown, but the dog is believed to be a mixture of many dog breeds, including the Rottweiler, Black and Tan Terrier, and German Pinscher. With its sleek coat, athletic build, and characteristic cropped ears and docked tail, the Doberman Pinscher looks like an aristocrat. It is a highly energetic and intelligent dog, suited for police and military work, canine sports, and as a family guardian and companion.

Dobermans are often stereotyped as being ferocious and aggressive. As a personal protection dog, the Doberman was originally bred for these traits: it had to be large and intimidating, fearless, and willing to defend its owner, but sufficiently obedient and restrained to do so only on command. The Doberman's aggression has been toned down by modern breeders over the years, and today's Dobermans are known for a much more even and good-natured temperament, extreme loyalty, high intelligence and great trainability. In fact, the Doberman's size, short coat and intelligence have made it a desirable house dog.
