The Rottweiler's Origins and History Source: Wikipedia. Country/Region of Origin: Germany Original purpose: herding, guarding Name: Named after the town of Rottweil, Wurttemburg; also known as Rottie. Historical notes: Rottweiler dogs date back to the days of the Roman Empire when legionnaires needed dogs to help drive the cattle that was the source of food. Some dogs that settled in Germany became what are now known as Rottweilers. They proved their worth in protecting cattlemen against robbers. They faced near extinction towards the end of the 1800’s but the demand in Germany for police dogs saw a great rise in interest in their breed.
