I just read your other post...you just really need to crack down on obedience and find another good instructor. I'm in Milwaukee and there is a GSD club near here, but its quite a hike for you to get down to us. There are a few Schutzhund trainers up there but its going to take a lot of work on your part. There is no such thing as an untrainable GSD, it just takes the right method and the right handler.
