I agree. Her feet look awful, I would consider looking into other farriers because there is way too much toe on that mare. It doesn't sound like you have had her too long, and it does take time to get feet back in shape. Get your farrier, or a new one, to work with her, maybe every 6 weeks to get that toe backed up. If you look at her foot from the side, there should be no dish from the coronary band to the bottom, it should be the same angle. I would also look into some hoof supplements to help it grow out healthy. Good luck!
