It's been a month, and Red's still off in the right hind. He's improving, but the improvement is very slow lately. He has a lot more trouble when he's having to sit back and use his hind end when slowing down or going downhill. At this point, I need to know what's going on so I know what to do with him - if it's a soft tissue injury, he may need some months off, or if it's minor, riding at the walk wouldn't hurt him. If it's hock arthritis flaring up, more exercise rather than less may be beneficial. If it's some other sort of joint injury, I need advice on how to deal with it.
Anyhow, my vet is coming on Monday to do a full lameness evaluation. My vet is very good and affiliated with a nearby veterinary hospital. She's good in lots of ways - listens well, has a pleasant manner with horses and people, is very thorough and careful, and is also very smart and knowledgeable. We'll know more on Monday . . . more vet bills . . . sigh . . .
