Personality
Doberman Pinschers are generally gentle, loyal, loving, and highly intelligent. Those familiar with the breed consider well-bred and properly socialized Doberman Pinschers to be excellent pets and companions, suitable for families with other dog breeds, excellent with young children, and even cats. The modern Doberman Pinscher is well known as a loyal and devoted family member.
Aggression
Although there is variation in temperament, a typical pet Doberman attacks only if it has been mistreated or believes that it, its property, or its family are in danger. According to the U.S. Centers for Disease Control, the Doberman Pinscher is less frequently involved in attacks on humans resulting in fatalities than several other dog breeds such as pit bull-type dogs, German Shepherd Dogs, Rottweilers, and Alaskan Malamutes.
The Doberman Pinscher has been used as a protection and guard dog, due to its intelligence, loyalty, and ability to physically challenge human aggressors. The breed was used extensively by the U.S. Marines in World War II, and 25 Marine War Dogs died in the Battle of Guam in 1944. There is a memorial in Guam in honor of these Doberman Pinschers.
