Probably is a mare. Bluebell's teats look just like that, even though she hasn't had a baby to nurse this year. I guess after so many, they just stay elongated like that.
Well, I don't know, these barrel horses are usually pretty young, and never had babies. They usually wait till their down on the barrel circuit to breed them. I think this one was young, he was just doing exhibitions on her.
