The Doberman Pinscher originated in the German Beer Breweries, developed developed in the 1890's to be the police or guard dog for security. This breed is well known as an intelligent, alert, and loyal dog. It can be very territorial yet it can be very good with kids.
Dobermans need a special blend to receive a good bio-nutritive value from protein. It requires higher amounts of amino acids and needs the same protein blend everyday.
Foods that are highly recommend are a blend of beef, corn, wheat and horse meat. You really want to stay away from poultry, ocean fish and white rice.
