The Rottweiler is considered to be one of the oldest breeds of dog with its origin to Roman times. These dogs were kept as herders or driving dogs. They marched over the Alps with the Roman legions, protecting the people and driving their cattle. Then at the beginning of the 20th Century, various breeds were needed for police service, the Rottweiler was among those tested. It soon became evident that the breed was highly suitable for the task and therefore they were officially recognised as police dogs in 1910.
