Rottweiler

The Rottweiler is a large size breed of domestic dog. The dogs were known as "Rottweil butchers' dogs" because they were used to herd livestock and pull carts laden with butchered meat and other products to market.

The Rottweiler was employed in its traditional roles until the mid-19th century when railways replaced droving for herding livestock to market. While still used in herding, Rottweilers are now used as search and rescue dogs, as guide dogs for the blind, as guard dogs or police dogs, and in other roles

"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." This breed is all about balance, endurance, proportionality, intelligence and strength.
