Lyn, don't apologize for your mare! Very few of us own perfect horses and we're not going to think less of you because you own one whose croup "isn't perfect." We have these guys because we love them and she's a beautiful girl.
She looks like she's blossomed under your loving care and she's doing much better. Kudos to you!
