This is all very interesting. Thanks for the replies so far.
Something about this is different and making me think it’s not just his normal crunchy hocks. He didn’t have enough space left to inject by the time his arthritis was discovered in the hocks. He was partially fused in one (can’t remember which). This was during a time when he felt like he had two flat tires in the hind end (felt like a gaited horse when trotting…so odd) and he literally could not lay down (he’d try and get stuck trying to bend his hocks and just get back up). Equioxx and Adequan got him straight and he’s been good since. I cut back the Equioxx when he was having ulcer issues, but I think he’s good there, so I’m going to give him his full pill again. He seemed less stiff this morning, but I did see him resting while eating breakfast. He’s out 24/7 at least, so that’s good for him.
And at least Adequan works everywhere, so if it is stifle or SI, it should help. I use Absorbine Flex Max joint supplement too, which I’ve found to actually help as well. It’ll probably take a little longer for that to start making a difference again since he was off of it for a few weeks.
I did notice that the right hind is also one that he’d gotten a “rope burn” (electric rope fence) on back in the summer. He and his neighbor tend to spar over the fence, often tearing down a strand. They SEEM to have stopped that foolishness now, which is good. Maybe getting his leg over the electric line taught him to cease the shenanigans. He never showed any lameness from the incident, but it’s just something I noticed when drenching him from stifle to hock in Sore-No-More and rubbing him down yesterday.
Anyway, he’s laying down and getting up still, which is a good sign. If he’s in serious pain, he stops even trying. And I think he’s sleeping in a wallowed-out sand hole in the pasture. I can imagine him getting his fat butt stuck in that and having to work a little harder to hoist himself up out of it.
Bless him. He’s got the easiest life a horse could have and he still has to be “special pony” and get all the things.
