I cannot for the life of me figure out if there is something wrong with my horse. He is very sound in that there are never any limb abnormalities when he works. The problem is that he will NOT hold chiropractic adjustments. I know when he is due because his canter gets shuffle-y and downhill and it feels physically impossible for him to rock back and push from behind in the canter. In fact, it feels difficult just for him to maintain the canter. When he is what I would consider comfortable, his canter is absolutely lovely and he has little trouble collecting and pushing from behind. The trot is not affected. I lunge him before I ride and I know he’s REALLY due if the canter is shuffle-y on the lunge. When the chiropractor comes, he is consistently out in his pelvis (rotated) and neck (varies between C5, C6, and C7 and left or right). His most recent adjustment held for about a week and a half before I had problems again with his canter.
The chiropractor has mentioned that this really isn’t right and even though he is known to play rough, the adjustments ought to be holding better. I agree. I’ve had my lameness vet check him recently (last week, one week out from the adjustment, which may have been too soon) and from jogging and palpations, the only issue she can find is that he palps slightly positive in his right hock, but does not flex positive.
The discomfort in the canter goes away when he has higher doses of bute (3-4 g/day). I haven’t tried a lower 1 am/1 pm dose yet as I only resorted to bute on one day last week for our dressage lesson, tried taking him off it at the beginning of the week, and went back to it to try and figure out if it does indeed make him better (the answer seems to confidently be yes).
My question, then, is has anyone had experience with this? What could be wrong in a horse that will not hold chiropractic adjustments but is comfortable with bute, when uncomfortable has trouble primarily in the canter, and is consistently out in the pelvis and neck when adjusted?
I’d have the vet out again, but I think I either need to have an idea of what to ask her to check for now or be prepared to have a lot of imaging that could potentially tell me nothing, or even worse be prepared to go to a hospital and spend disgusting amounts of money trying to figure out if something truly is wrong.
Feel free to ask any questions regarding management or history if you think I’m leaving out pertinent information- I just tried to keep it brief-ish and to the point.
