About two months ago, my friend was riding my gelding and I was riding my mare. We were loping down a trail in town (we have horse trails instead of sidewalks) and he did a little mis-step. She got off of him and pulled a rock out from a tender spot in his frog. He was a little gimpy, so we stopped at the bar, tied them up, and gave him some rest. We came out about an hour later and he would not move. Period. I had to call another friend to come pick me up and take me to my trailer, so I could drive back and load them up. Bo would hardly get in the trailer. It never absessed, but I soaked that foot in a salt solution twice a day for several days, and I kept him locked in his stall. I gave him bute for a couple of days, too. He was still a little bit tender for a while, but the shoer came out about four weeks later and said everything was fine. He was walking normal again, and Lige said he had no tender spots in his foot. So, I go out tonight to feed, and Bo will not move. He walked gingerly to his stall, I picked that foot, and found another small rock. He's pointing his toe, will not pick up his other front foot (but will pick up both rear) and does not want to put weight on it. AGGGGHHHH. I gave him some bute... I'm out of salt and the feed stores are closed. I'll have to wait until tomorrow. Any suggestions? Is this just bad luck or could there be an underlying problem?
