Additional information (Wiki): The Rottweiler, or Rottweil Metzgerhund ("Butchers Dog"), is a "medium to large size, stalwart dog" breed originating in Germany as a herding dog. It is a hardy and very intelligent breed. Rottweilers also worked as draught dogs, pulling carts to carry meat and other products to market. "Rottweiler breeders aim at a dog of abundant strength, black coated with clearly defined rich tan markings, whose powerful appearance does not lack nobility and which is exceptionally well suited to being a companion, service and working dog."

The Rottweiler was kept busy in these traditional roles until the mid-19th century when railroads replaced droving for getting livestock to market. Although there are still Rottweilers working stock all over the world, many other roles have been found for this versatile breed.

According to the FCI Standard, the Rottweiler is good natured, placid in basic disposition and fond of children, he is very devoted, obedient, biddable and eager to work. His appearance is natural and rustic, his behaviour self assured, steady and fearless. He reacts to his surroundings with great alertness.

The American Kennel Club says he is basically a calm, confident and courageous dog with a self-assured aloofness that does not lend itself to immediate and indiscriminate friendships. A Rottweiler is self-confident and responds quietly and with a wait-and-see attitude to influences in his environment. He has an inherent desire to protect home and family, and is an intelligent dog of extreme hardness and adaptability with a strong willingness to work, making him especially suited as a companion, guardian and general all-purpose dog.

Rottweilers are a powerful breed with well developed genetic herding and guarding instincts. As with any breed, potentially dangerous behaviour in Rottweilers usually results from irresponsible ownership, abuse, neglect, or lack of socialization and training. Inherent breed characteristics are not a factor.
