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 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.
Although a versatile breed used in recent times for many purposes, the Rottweiler is one of the oldest of herding breeds. A multi-faceted herding and stock protection dog, it is capable of working all kinds of livestock under a variety of conditions.
