Confident, intelligent, friendly, hardworking, and possibly dominant, the Rottweiler temperament is one of patience, courage, and loyalty. Because of their history as guardian dogs and cattle herders, Rottweiler temperaments make them naturally bold and assertive--though they're normally not aggressive unless conditioned to be that way. In any case, the Rottweiler personality will need some shaping, starting in puppy-hood if possible; extensive obedience training and socialization, done early and often, is a must for this breed.
If these dogs learn respect as puppies, they'll turn into well-balanced, calm, friendly adults--though their protective instincts will always remain. Regardless of the Rottweiler behavior with family members, extraordinary caution must be taken when the dog is around strange people or animals, as its instinct is to protect its people, which it will often do through confrontation unless taught otherwise.
Luckily, one of the best Rottweiler characteristics is that the breed is highly willing to please, so Rottweilers will respond well to training. It's imperative that trainers establish themselves as superior from the very beginning, too. Firm (but never harsh!), consistent, reward-based training methods are best.
And of course, the most fantastic of Rottweiler traits is that their abilities as watch- and guard dogs is unmatched. Though they're not frequent barkers, Rotties are alert and fearless, and will investigate unknown sights and sounds--and will be able to neutralize most potential threats.
