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 fulfil especially in Europe.

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. Males are characteristically larger, heavier boned and more masculine in appearance. The Rottweiler should possess a fearless expression with a self-assured aloofness that does not lend itself to immediate and indiscriminate friendships.

He has a strong willingness to work. In examining a Rottweiler, one should bear in mind that this dog reacts with alertness to his master and his surroundings, and in performing his function in life, the Rottweiler is not expected to submit to excessive handling by strangers. However, the judge shall dismiss from the ring any shy or vicious Rottweiler. A dog shall be judged fundamentally shy if, refusing to stand for examination it shrinks away from the judge; If it fears an unexpected approach from the rear; if it shies at sudden or unusual noises to a marked degree. A dog that attacks or attempts to attack, without provocation, either the judge, or its handler is definitely vicious. An aggressive or belligerent attitude towards other dogs shall not be deemed viciousness.
