Additional information (Wiki):The Dobermann Pinscher (alternatively spelled Doberman in many countries) or Dobermann is a breed of domestic dog. Dobermann Pinschers are among the most common of pet breeds, and the breed is well known as an intelligent, alert, and loyal companion dog. Although once commonly used as guard dogs, watch dogs, or police dogs, this is less common today. In many countries, Dobermann Pinschers are one of the most recognizable breeds, in part because of their actual roles in society, and in part because of media attention (see temperament). Careful breeding has improved the disposition of this breed, and the modern Dobermann Pinscher is an energetic and lively breed suitable for companionship and family life.

Doberman Pinschers are the target of a mistaken stereotype of ferocity and aggression. 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 only do so on command. These traits served the dog well in its role as a personal defense dog, police dog or war dog, but were not ideally adapted to a companionship role. In recent decades, the Doberman Pinscher's size, short coat, and intelligence made it a desirable house dog. Although these dogs are mistaken for their aggression, they are extremely loyal. They can easily learn to 'Respect and Protect' their owners. In response, they are excellent guard dogs that protect the ones they love. There is evidence that Doberman Pinschers in North America are calmer than their European counterparts because of these breeding strategies Because of these differences in breeding strategies, different lines of Doberman Pinschers have developed different traits. Although many contemporary Doberman Pinschers in North America are gentle, loyal, loving, and intelligent dogs, some lines are bred more true to the original personality standard

In addition to the studies of canine personality, there has been some research to determine whether there are breed differences in aggression. In a recent study, aggression was divided into four categories: aggression directed at strangers, owner, other strange dogs and rivalry with other household dogs. This study found that the Doberman Pinscher ranked relatively high on stranger-directed aggression (behind the Dachshund and Chihuahua), but extremely low on owner-directed aggression. The Doberman Pinscher ranked as average on dog-directed aggression and dog rivalry. Looking only at bites and attempted bites, Doberman Pinschers rank as far less aggressive towards humans, and show less aggression than many breeds without a reputation (e.g., Cocker Spaniel, Border Collie and Great Dane). This study concluded that aggression has a genetic basis, that the Doberman shows a distinctive pattern of aggression depending on the situation, and that contemporary Doberman Pinschers are not an aggressive breed overall.
