The Rottweiler must be trained starting early in his life. Leadership, puppy socializationbasic training classes, and living in the owner’s home are key to raising a well-mannered Rottweiler. Rottweilers are “people dogs” who do not do well isolated from humans and life experiences. No matter the breed, dogs must live in this world complete with strange animals and people. One expert in the breed notes, “As a Rottweiler owner, it is my responsibility to spend time, energy, and money giving my dog the opportunities to learn on a day-to-day basis.” The breed is intelligent, highly trainable and wants to please, although some may be stubborn. It is very important that discipline be consistent, fair, and firm, without being rough. Roughhousing with the Rottweiler may encourage aggression and should be avoided. Rottweilers excel in many canine sports, and the breed works with a human partner in many functional roles.
