My first golden was dx'd with Cushings. I believe now that he was in the very early stages of the disease. He was treated with L-Deprenyl (which is a very strong med) and his levels crashed to Addisonian It was a roller coaster ride of tests and med adjustments for about 6 months. It probably could have been managed and I know of dogs who have lived long lives with the disease but we eventually found out that Kody had lymphoma (unrelated) so the Cushings took a backseat.
