The Rottweiler is a breed of domestic dog, regarded as medium-to-large or large
The dogs were known in German as Rottweiler Metzgerhund, meaning Rottweil butchers’ dogs, because their main use was to herd livestock and pull carts laden with butchered meat to market.
This continued until the mid-19th century when railways replaced droving. Although still used to herd stock in many parts of the world, Rottweilers are now also used as search and rescue dogs, guard dogs, and police dogs.
The Rottweiler stands 61–69 cm (24–27 in) at the withers for males, 56–63 cm (22–25 in) for females, and the weight must be between 50 and 60 kg (110 and 132 lbs) for males and 35 and 48 kg (77 and 105 lbs) for females. Weight must be relative to height.
