The Doberman Pinscher originated in the shadows of Germany's beer breweries. Today the Dobe is internationally renowned as a security dog. It has an extremely high degree of loyalty to its master and can be very territorial, yet its temperament also makes it good with children.
The Doberman Pinscher needs a special blend to receive good bio-nutrietive value from protein. When compared to other breeds of the same body weight, it requires higher amounts of certain amino acids. The protein should be high in Phenylalanine and Thyrosine. Since the bulk nutrients of the area where the Doberman Pinscher developed were high in these essential amino acids, this breed requires this same protein blend today. Food sources found in the Doberman Pinscher's native environment included grain crops used for brewing German beer with pork and beef meat sources.
The protein sources would be the best for this breed of dog are a blend of beef, corn, wheat, and horse meat. Conversely, the worst blend would contain high amounts of poultry, ocean fish, or white rice.
Nutritionally the Rottweiler is a breed that should be treated as a puppy for 18 to 24 months, even though they usually reach their full adult size in 10 to 12 months. The Rottweiler's skeletal systems and muscle structure are both slow to develop. A 12-month-old dog may appear to be fully grown, but it is still a puppy in terms of its nutritional needs. When this breed is fed an adult dog food too early, there is a higher chance for developing dysplasia or other bone and muscle problems. When kept on the puppy formulas and schedules until they become adults (nutritionally) they will have fewer problems later.
The nutrients of its native Italy included high carbohydrate grain products. The nutrients found in the mountains of Southern Germany were lamb, poultry, goat, and cheeses. Note: all of these nutrients are high in their fat content.
The ideal base diet for the Rottweiler would consist of a blend of lamb, poultry, dairy products, and wheat. Foods for this breed to avoid would include fish, horse meat, beef, corn, soy, or white rice.
