Confident, bold, alert and imposing, the Rottweiler is a popular choice for his ability to protect. As befitting his self-assured nature, he tends to be headstrong and stubborn and is often domineering. He can be reserved, often wary, toward strangers. He may be overly protective if he perceives that his family is being threatened, and he may also attempt to "herd" children. This is a powerful breed that needs socialization, consistent training and daily exercise to be the best he can be , a loyal family member and guardian.
