So sorry to hear that. My RB Buttons had cushings disease as well as diabetes and blindness but he still had a good quality life up until the week before we put him down. He lived for a few more years after he was diagnosed. His hair loss wasn't too bad until a few months before he died. He lost all the hair on his ears and then his coat started thinning much later on. If you look in my signature you can kind of see the hair thinning on his waist and the complete loss on his ears.

We had to give him prednisone every other day I think, but I don't remember too well. I hope Reggie can get the proper diagnosis. They can lead a pretty normal life once they get help. Good luck
