He seems a bit off going to the right, mostly at the canter. When I lunge him to the right he seems to trot okay. But when I ask him to canter he is very reluctant. He rather trot exptremely quickly than pick up the canter immediately. When he finally does canter he is short strided on the right front leg. He doesn't want to keep the canter for long and seems a little uncomfortable. But he seems perfectly fine trotting and cantering to the left.
A friend mentioned it might be a hook bruise that's causing some pain. I checked his leg and no hot spots or swelling. He was fine when I messed with his leg and poked and prodded at him. I'm really not sure what to do.
Any suggestions on what may be the problem, what I should check for or some possible treatments/remedies? I would greatly appreciate any help.
