My Horse Bucks on A Circle, What's Wrong?

[mongy46]

My horse has just started to kick out and buck on a left circle, what could it be?
It when we ask for canter, and when not ridden keeps resting his near hind, back leg.
He seems fine in a straight line.
Any suggestions please?

he might be stiff down one side, my horse started doing that and we called the physio who said he was a bit stiff and sore behind the saddle on one side and that's why it was just affecting the one side

Also to add to whats allready been said I would be checking the fit of your saddle. May be that it is pinching him. Especially if he is more build up behind one shoulder than the other, as this could be making it tighter on one side more so than on the other. Which may be why he is acting out on the one rein.

Thank you. The saddle was tight so we changed it, so will prob have back lady next.
