Energetic, affectionate, playful, and stubborn and aggressive at times, this crossbreed can be a welcome addition to the family--but firm and consistent training, along with early socialization with children and other pets if possible, is highly recommended. The Bull-Boxer temperament is normally one of great loyalty to its human family; in return, dogs of this breed need plenty of attention and affection from their owners. Bull-Boxers love nothing more than cavorting around the yard (or even the living room, if you let them!) while playing games and performing tricks. And the more physical activity with these dogs, the better--because a bored Bull-Boxer is often a destructive one.
As previously mentioned, this crossbreed can be quite headstrong, and will need firm training from a person they see as the "alpha" pack master. One training method that Bull-Boxer owners have said works well for them is a scientific "task-reward" system called clicker training. Clicker training is a scientifically proven practice that Bull-Boxer owners say works extremely well for their dogs.
As to watch- and guard dog abilities, the Bull-Boxer is nearly unmatched. This crossbreed is extremely protective of its loved ones; a Bull-Boxer is normally wary of strangers, and might be aggressive towards them if it believes they are a threat. The good news is that, unlike similar breeds like the Pit Bull, a Bull-Boxer will not attack with intent to kill, and will normally calm down after the perceived threat is neutralized.
