Doberman dogs never ran around a flock of sheep, did not get shot ducks out of the swamps, did not lie on sofas, decorating the interior. For their entire short century (the breed is very young), Dobermans were an ideal police dog. German breeding has created a strong, courageous, reckless, and at the same time balanced and controlled service breed, capable of searching, pursuing, and actively detaining an intruder.
The protective qualities of Dobermans are beyond criticism: in every representative of the breed, the propensity to protect and preserve is laid down from birth. Even an absolutely untrained dog with gaps in social adaptation and upbringing will try to guard the owner, guard his house, and his property.
