Rottweilers are a powerful breed with well-developed genetic herding and guarding instincts. Potentially dangerous behavior in Rottweilers usually results from irresponsible ownership, abuse, neglect, or lack of socialization and training. However, the exceptional strength of the Rottweiler is an additional risk factor not to be neglected. It is for this reason that breed experts declare that formal training and extensive socialization are essential for all Rottweilers. According to the AKC, Rottweilers love their owners and may behave in a clownish manner toward family and friends, but they are also protective of their territory and do not welcome strangers until properly introduced. Obedience training and socialization are required.
