The two year old MFT's update is as follows:
His feet are trimmed, and it did stop his stumbling, his hooves are cleaned daily, brushed daily, and rode daily, walking, slow trots. So slowing him down, and watching him closely. Though today we were going at a very slow trot, could have jogged with no effort alongside him. Flat ground on the dirt road, and he was not tripping or stumbling, but he just fell forward. He skinned his nose, his knees, and I got him, checked all hooves, nothing in them, not even a pebble. The shoes were not loose, they were on firmly, and his hindquarters equal his chest so he is not pushing himself over. I walked with him after that, got back on and rode him, got off and walked, and there was no tripping. I can't explain why he did this after doing so well for so long, but he got medication to keep infection away.
