I have raised full-blood shepherds, training them in obedience with hand signals. My son has trained a pitbull in attack. We usually let the protective instinct of the animal serve without additional training; however, this year we have a different situation. We have a full-blood (long-haired) german shepherd now 3 yrs old who is obviously an "alpha" female. We also have a loud-mouth drunk for a neighbor who teases her on a daily bases. I am concerned that should this drunk wonder over sometime, he might not like his greeting; and though I have a strong dislike for this guy, I don't want my dog hurting him too badly. Thus, I want this shepherd trained well. I would appreciate information (pros and cons) on attack training and on schutzhund training, knowing these are similar. (I also have heard there is legislation out concerning attack training and do not want to do anything causing my family problems.) All the information I can get will be helpful.
