So I just adopted a king German shepherd from the humane society, he’s an insanely well behaved dog, not much information was given except he has serious anxiety and chewed off his own tail and currently has a Doberman stub. So as I said he’s very well behaved, 0 aggression, literally have yet to hear him bark or growl once within a month of having him. He’s such a good boy but clearly struggles with something, he’s very food and toy motivated but listens half ass regardless. He doesn’t appear to like being pet too much he seems to freak out when I show affection. They claim he’s 4 but I struggle believing that due to his energy level matches that of a 2 year old, I give him jobs all the time, a lot of searching and exercise of course, I could give him more but he gets enough. I want him to be comfortable here and just be himself I know it will take time but if it helps he takes 400 mg of trazodone a day. Any advice?
