BRIEF HISTORICAL SUMMARY: The Rottweiler is among the oldest breeds. Its origin dates back to Roman times, where it was created as a guard dog and cowboy. These dogs immigrated with the Roman legions across the Alps, guarding men and touching the flock. On the outskirts of Rottwell, they met the dogs in the area. Then, there was a miscegenation. The main task of the Rottweiler was again to lead and guard large flocks, large animals and the defense of its owner and his assets. It got its name from the old city of Rottweil: Rottweiler Metz-gerhund (Rottweil’s butcher dog). Butchers created this breed for the sake of display, with no use for it. Thus, over time, this walking dog became more used as a traction dog. At the beginning of the century, when researching different breeds for the police function, the Rottweiler was also evaluated. In a short time, he proved to be extraordinarily suited to the tasks of the police service. For this reason, in 1910, he was officially recognized as a police dog.
