Spencer came to us a very territorial, insecure, and dog-aggressive dog. He is now learning how to socialize in a pack. He has been doing very well with the dogs we have here as well as dogs that come in for boarding. He has learned to relax on "Place" when in the house and he has also learned to sit and wait at doors before coming in or going out. He is now 90% off-leash. We occassionally use a leash with him during his obedience, but for the most part, he no longer has to have a leash attached.
