So... Fleck has started roaring much worse lately. I wasn't entirely convinced he was roaring, because it didn't start til later in life and progressed slowly. But sure enough, he sounds like a roarer when we're galloping. Then it progressed to when we were cantering and now lately even at the trot. :(
So... I took him to Dr. Browns and we scoped him. Sure enough... 35% paralysis of the left arytenoid. But... it's not a tumor. It's not something that will require surgery.It's just going to potentially limit his gallops. Although so far it hasn't seemed to.
