We suspect our 14 year old mixed breed dog has Cushings Disease. He also has a moderate to severe anxiety problem (whining a lot, licking obsessively, can't settle down, etc) that our vet says may be related to the Cushings. Any thoughts on this from anyone? He also has the other obvious Cushings symptoms, panting all the time, drinking lots of water, pot belly, etc. He takes doggy Prozac but it really hasn't helped with the anxiety.
