Many people believe the Rottweiler to be descended from a mastiff type dog which the Romans used when they conquered Europe. The Romans used these dogs primarily for herding the cattle and sheep needed as food for their armies. The modern breed of Rottweiler is believed to have been developed in Germany in a district known as Rottweil, hence the name Rottweiler. The Germans used these dogs as herd dogs for their farming animals.
Currently they are frequently used as guard and police animals. Some people have trained these fine animals to be hostile and many sad stories have resulted from these situations. However, a Rottweiler which has been properly trained, will be as gentle as any other breed of dog.
