We moved about 1 1/2 months ago and my 2 year old Whippet destroyed some curtains and door frame when he was left alone. I took him to the vet and he was put on medication for a couple of weeks to help the anxiety. I didn't leave him alone for a few weeks and when I did he was fine. Then yesterday I went out and he did damage again, he had seen a dog the night before that he used to play with at our old house so I don't know if that set him back. Now I don't know what to do as it worries me that this could keep happening and he is such a good dog normally and my stress levels are huge.
