The Rottweiler is the current "fad" guard/macho dog of the moment. For four years running, it has been the second most-popular AKC registered breed. Don't be swept up by the hype, or the fact that you neighbor, aunt, sister, or best friend has one. The Rottweiler is a large, powerful dog and along with ownership comes much responsibility. Rottweilers require extensive socialization from an early age. Are you willing to carry your puppy for several months, (he shouldn't be walking in public places until he is fully immunized at around 16-20 weeks), exposing him to the sights, sounds and people he will encounter as an adult? Because of their size and strength, obedience training for your Rottweiler is a must. Weekly group classes for 6 to 12 months is generally considered a minimum. Rottweilers are "people" dogs.
