Contrary to popular belief, the Rottweiler is not a dangerous breed of canine. However, it is often intimidating or seen as a danger because many Rottweilers have been trained to be guard dogs. Sometimes the training is more than necessary turning the canine into an aggressive guard dog. This is not normal, however. The Rottweiler is actually a naturally born loyal, friendly, and protective breed. In fact, the Rottweiler is often used as a search and rescue dog, guard dog, police dog, and even a guide dog for the disabled. The canine is medium to large and was first developed in Germany as a herding dog. They were also used to pull carts and to perform other acts of labor until the mid 19th century.
