i'll agree that you need to get him the most experiences while he is a pup that you can. The more socialized you can get him the better, take him to stores with you, take him to meet friends kids, other dogs as many new things as possible that way they are not afraid of things when they grow up. If you going to shoot guns around him start out slowly with a cap gun in the other room while he is eating then mover closer and closer with time.
