I notice that you mentioned that you have a greyhound? I recently adopted one and I wonder if I could ask you some questions. How old is yours and how old was she when she was adopted? Mine is 4 and we adopted her about a month ago. She is an angel and was surprisingly well trained already, but she has TERRIBLE separation anxiety and is not getting any better. Did you have any experience with this or any advice? We've tried everything from leaving a radio on to treats and Kongs to trying to ignore it and nothing is improving. Any advice?
