The old man (Thoroughbred) is 27 today. He's got a weird coat... His winter coat is really long, which makes sense as it was a very cold winter and he was not blanketed. It's shedding out, but the best way to get the hair out is to pinch the ends of a clump of hairs and just pull them out. The coat underneath is longer than a normal summer coat, but I'm not sure if it's actually his summer coat or another layer of the winter coat. What I find rather odd is that on his neck, the hair left after shedding is extremely fine and soft and downy, and again longer than a typical summer coat. It's like the fur cats have right behind their ears. His coat is not curly/wavy, and he doesn't have any other symptoms of Cushing's.
Any thoughts? I am going to call my vet! But it's breeding season and she's busy, so I want to have some ideas before I call so I'm not just bouncing ideas off her.
Laurie, which tests do you use? Cornell has 5 different tests listed for Cushing's....
Dexamethasone suppression is out, as it requires a second sample 19 hours later.. I'll discuss everything with my vet, and then have my dairy cow vet dad actually draw and submit the blood. So drawing a sample the next day is just about impossible.
Merrygoround, I know TBs aren't immune, although they are generally a thousand times better than other breeds .
My retired TB started to not shed out his winter coat a few years ago (he's now 25). My vet felt that testing for Cushings might be inconclusive in his particular case and recommended instead that we put him on Thyro-L. He's been on it ever since and now sheds out his woolly mammoth coat every spring.
