Hello and welcome
.
If your vet is struggling for answers, I really would recommend going to a specialist, if you can. This is where I go for my specialists - I'm here in Phoenix (we've seen internist Dr. Janet Bailey, just fyi, for Wylie's Atypical Cushing's and we've been to the Derms):
Arizona Veterinary Specialists
This is where I go for my general vet care (we see Dr. Bastek, but I also really like Dr. Roe and Dr. Koch):
University Vet
Please let me know how else I can help
