text: Rottweillers have been in use as cattle driving dogs in Germany since the middle ages, and although their complete origins are obscured by history, most believe that they are the descendants of the large Drover dogs that were employed by Roman cattlemen and butchers as early as 700 A.D. to protect cattle and drive them to market, mixed with some local German breeds such as the Appenzeller Sennenhund and the Bernese, Entlebucher, and Greater Swiss Mountain Dog breeds.
