Hello, Everyone at Pet Talk. Just to bring this to a conclusion, my "aggressive dog" has met with his new owners a time or two and seems to be o.k. with them for now. He will be making a few weekend trips to their home before moving there permanently next month. I hope that this is the right decision -- it feels like it's the right one, but I also can't help feeling that I have given up on this dog too soon and too quickly. As I stated before, I've had him since he was a pup that could fit into my coat pocket. Any ideas on how to overcome the guilt and the emptiness I am feeling inside? Thank you all for your advice. I don't know what I would have done without this site to assist me through a very difficult time.
