In the hands of a responsible owner, a well-trained and -socialized Rottweiler can provide both excellent personal protection and loving companionship. A badly trained or insufficiently restrained Rottweiler, however, can be extremely destructive, and pose a significant physical threat to its owner or other humans or dogs on account of its size and strength. In general, Rottweilers are quick to learn and eager to please, and thrive on mental stimulation. They can also be strong-willed at times, however, and should thus be disciplined in a firm, consistent manner. Rottweilers are playful animals who constantly demand attention from their owners and will find creative and often destructive ways to get it if they are excessively neglected.
