The Rottweiler was developed from the dogs used by the Roman legions to herd and guard the cattle brought by them to feed their legions. The butchers of Rottweil, Germany, developed the dogs to drive cattle to market and to protect their money bags which were tied around the dogs' necks. It was an arduous task to drive the cattle and a strong dog with staying power, full of self will and physical strength was needed. In the beginning of the 20th century these dogs were found particularly well suited as a police dog, a function they still fulfill especially in Europe.
The ideal Rottweiler is an above medium-sized, robust, and powerful dog, black with clearly defined rich tan markings. His compact build denotes great strength, agility, and endurance.
