Rottweiler

The Rottweiler is a medium to large size breed of domestic dog that originated in Rottweil, Germany. The dogs were known as “Rottweil butchers’ dogs” (German: Rottweiler Metzgerhund) because they were used to herd livestock and pull carts laden with butchered meat and other products to market.[1] Some records[which?] indicate that earlier Rottweilers may have also been used for hunting, although the modern Rottweiler has a relatively low hunting instinct.
The Rottweiler was employed in its traditional roles until the mid-19th century when railways replaced droving for getting livestock to market. While still used in herding, Rottweilers are now also used in search and rescue, as guide dogs for the blind, as guard or police dTitulo atlernativoogs, and in other roles.[2]
