I am trying to do a lot to help Shane over come his aggression with other dogs. However, some days I feel like it is helpless. If I think I am making progress one day..the next day it is like he takes 2 steps back. I was looking up some books online and I was wondering if anyone heard of Patricia B. McConnell, she wrote "The Cautious Canine" and the "Feisty Fido." If anyone can tell be about these books or the author...thanks!
