Training a Guard Dog

CHOPZ was given to me because my family who had him could break his aggression or control him . . . I habe him trained really well now. Imo you have to understand hownto read and project energy, that's where training is at, especially with very active energetic breeds like a King Boxer. Btw He is Full Blooded King Boxer, German boxers have the smashed snout more so Kings are bigger
