What I mean by disuniting is that he cantering correct in the front but at the back he cantering counter counter canter sort of. He does it maybe because something might be hurting him. Maybe I didn't explain properly, he does it because also maybe because of inexperience and its really annoying because in the front he has the correct canter but he has the incorrect canter on his back legs. This normally happens when going into corners, because that's when they normally get unbalanced, the problem is I don't know how to get rid of it. The thing is that I do show jumping and I loose tons of time when going around a course and its really uncomfortable going round a corner. I loose time because I have to do big corners for him not to disunite as easily. If anyone has any more suggestions I would be very happy. Thanx.
