The Rottweiler is a breed of domestic dog, regarded as mediumtolarge 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 mid19th 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. rottweiler dogs 101, rottweiler health problems, rottweiler dog
