Yes it is terrible . My first encounter with it, animal or human. I can believe stress influences it a lot, as the onset with Zeus was when his beloved sister/litter mate Tiger Lily died. He really mourned for her and it was shortly after that he was diagnosed with cushings. Yes, so right Pawbla, staying strong and keeping positive, pulled the boy through last time, so will stay the same this time!!!!!!!!!!!It's an awful disease... I don't know any other dogs that suffer from it, but I've seen it in humans. It's terrible! I've heard stress influences a lot on it, so keeping a positive attitude will help a speedy recovery!
