I stopped at the barn and rode on my way home from work last night. Bella was eager and energetic and stepped out beautifully, picking up her fast, rhythmic walk as we warmed up in the arena. Even so, I know her movement so well that I could tell that she was just a teeny, tiny, infinitesimal bit off. I thought it might be the footing because the ranch just laid down dust control and raked it in so the footing was a little deeper than it usually is, but it wasn't bad by any means. Asked for a trot and I could still feel it, just a tiny little hint of a head bob and unevenness. Got off, checked feet, no stones, shoes fine. Trotted in hand. She's short-striding just a teeny tiny bit on her right front. A little bit of heat just at the coronary band. She's not lame. No one but me or a skilled lameness vet would probably notice it. But she's just a wee bit off. So I'm thinking maybe working on a high abscess? I can't think of anything else that would cause some heat in that location. Can you? It's kind of past abscess weather here but if it's that high, it could mean she's been working on it quietly for a while as it traveled. I'm just at a loss to think of anything else that would present that way. So guesses?
