I would like all the information and advice possible on starting my dogs training. He's only 4 weeks old and as I understand him being so young away from his mother can cause some training aggression issues down the road. I'm going to be enrolling him in petsmarts puppy classes and follow up with the subsequent two courses for older dogs. I also want to start him in weight pulling when hes the appropriate age as a sport for exercise for him and something fun to do with my dogs for me. I'm a first time pit owner and want to train Tyson right so that he is a model pit citizen ! Any information, Advice is greatly appreciated.
