My Dartmoor pony mare, who is 26 years old, has Cushing's. I think she was 23 when she was diagnosed. She's on pergolide right now, which helps a lot. Last year her coat was perfect. But this year, she just won't shed out her winter coat. Does anyone here have any advice on what else we could do to help her? We even have an acupuncturist/vet that comes out once a month to help her. Also, what are everyone else's experiences with Cushing's? How long do they last after being diagnosed? How do they die?
