The Rottweiler is thought to have descended from the Italian Mastiff and was bred in Rottweil, Germany. They were used as a herd dog in the middle ages. During the 1800’s the breed almost reached extinction, but passionate breeders brought the numbers up early in the 20th century. Throughout history the Rottweiler has been used for everything from tracking and police work to schutzhund and competitive obedience.
