Well, Andolu is still not any better. He actually seems to be generally sore to me, so I guess I'll have to ask for ultrasounds or x-rays. There is still absolutely nothing I can point to. He could have started to roll and done something to himself then, but that's kind of a wild guess. I am feeling guilty about the fact that we live in such a hilly area. They do have a sloping pasture, with several wide flat areas, but Mira doesn't seem to mind it. Neither do the other horses that live around here in the same terrain. I keep wondering if going up and down our steep road did something to him... Sometimes it seems to aggravate Mira's hip arthritis. Below is the section of road right above their pasture. A few hundred feet after that it levels out and turns into dirt road with various hard, weedy places you can explore off the road. That is pretty typical for our area. This is a place with a LOT of horses, too, but maybe it is hard on them? I don't know what to think.
My main worry in this whole thing is that he might have just been truly wrecked by the racing. I knew it was quite possible that he would not be sound for riding when I got him, and I took the risk that he would have to be a pasture pet. But it is a different matter altogether for him to not even be able to tolerate exercise being led - that sort of unsoundness is not a good thing at all. We'll see how this turns out over the next few days.
