My son, who lives with us right now, has a 1.5 year old PitBull pup. He is adorable and sweet most of the time. We are having problems with him though. He starts fights with my Chocolate Lab if he is getting attention, he is digging up my yard and he is tearing up everything. He shredded my husbands grass catcher, my japanese maple tree, and a barbaque cover. He is really a smart dog and I love him, but I need help because if he does not change we are going to have to give him away. Any tips?
