Known for its great strength, endurance, and protectiveness, the Rottweiler can be a good-natured, playful pet. It can also be a highly challenging breed. In the right hands, a Rottweiler can be the best security system in town, and at the same time, an affectionate friend to the whole family, always ready for fun and games. The well-bred, well-trained Rottweiler has the courage of a lion and is happy to obey. In the wrong hands, a Rottweiler just as easily can become an unruly beast, a menace to all that come near.
