Maisie's doing very well seems to be cured, I tried out some keratex on her soles which worked surprisingly well, I was skeptical about her hock issues but wanted to try this before getting a second vet out, the farrier said that she's just a wimp, which being a tb is very true...
She's working lovely now her soles are a bit stronger, I'm defiantly keeping a eye on her though, cause although she seems to be doing well its all touch and go because of her past... We shall see!
One can be related or cause the other. Pain in one area in a horse will often make the horse try to compensate/reduce the pain by changing the way they go, which make them go unnaturally and can then cause other areas to have problems.
I think you should have both her back and hind end checked out by someone specializing in lameness. She could have back soreness causing her to move out oddly, or leg issues causing her to try to compensate with her back.
I was skeptical too, but since the vet blocked the foot and she went sound, that would indicate that is the location of lameness.
I too am surprised that the keratex worked this well. I would consider pads on one hand. On the other hand, pads add more stuff to the bottom of the foot and with a thin walled Thoroughbred foot that can spell trouble. PAds also can retain moisture and make a thin walled hoof a bit soft.
If she it going well now, just keep up the good work. Do you have pictures of her?
