I never even knew that this was a problem with some horses. I never even knew about it until today when I read about it in my animal science textbook.
But it's got me worried about Athena.
Roaring is apparently when a horse breathes in deeply, and one of the vocal cords (I think) doesn't move up all the way and thus creates the roaring sound.
Athena does when she's really excited. She'll prance around, gallop, buck, rear, do what excited horses do out in the pasture then she'll stop all of a sudden and... roar.
I always just thought it was an Athena thing. She's never had trouble breathing or anything like that. She never does it any other time only when she's running around excited. She's a very fast horse and loves to jump so the whole roaring thing hasn't affected her in any way like that. She's always done this. Since it's not a big deal does that mean that she doesn't have to have surgery? Or is it something that has to done no matter what?
