It stands on its pads and is not usually heavy-footed. Dobermanns have markings on the chest, paws/legs, muzzle, above the eyes, and underneath the tail. Although they are considered to be working dogs, Dobermanns are often stereotyped as being ferocious and aggressive. As a personal protection dog, the Dobermann was originally bred for these traits: it had to be large and intimidating, fearless, and willing to defend its owner from attackers (especially other guard dogs), but sufficiently obedient and restrained to do so only 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.
