He's a 6-month old miniature horse we've had for about 2 months. Nice little guy - was really wormy when we got him so I had the vet out and had him looked at. He's since gained well, is nice and energetic, coat is filling in nicely. Anyway, I don't think that's related to the foot dragging, but what do I know. We've seen it 3 or so times in the past 3 or so weeks... he will drag his left rear hoof as he's walking around. Is it just b/c he's got a rock in there or something? This morning, for example, he was doing it when we went out to feed first thing. I checked him out thoroughly - no scrapes, scratches, anything at all. I cleaned out his feet, and it was just the usual gunk. Maybe a small rock? But then he was doing it again around noon, and NOT doing it at 5 pm. I'm stumped. I am planning to have him gelded in the next several weeks (vet said after the worming has subsided), so I can at least get his opinion, but thought I'd check here first to see if this is common or not. I googled "horse dragging hoof" and there are all kinds of bizarre explanations.
