The Doberman Pinscher was developed in Germany in the late 1800s by Louis Dobermann, a tax collector who wanted a capable dog to accompany him on his rounds. The result is a sleek, muscular working dog with a short, glossy coat in black, red, blue or fawn with rust markings. Many in the US still have cropped ears and docked tails, though natural ears and tails are increasingly common.
At home, many Dobermans are affectionate, sensitive dogs that stick close to their people. They're typically watchful with strangers and do best with early socialization and consistent, reward-based training. Plan for plenty of daily exercise and mental work, plus regular veterinary attention to heart health, since dilated cardiomyopathy is a serious concern in the breed. Temperament varies from one Doberman to the next, so spend time with the dog you're considering.
