Well, When I lunged her she will canter with the wrong leg lead first than I have to ask her to come back to trot for a several time before she can canter with the correct leg lead.
And I'm a bit confuse with her because before that she use to canter with right leg lead. And never left, but after my coach rode her about 4-5 times she can canter at both side correctly. But about 2 month ago she start to canter only by her left leg lead. So I'm very confuse with her and why is she like that.
I change the saddle from all propose to Dressage saddle by the time she change her way of cantering. So maybe is this why? I'm not really sure :]
Changing saddles is a major red flag, especially if she used to canter on both leads well. If the saddle isn't fitting her correctly it can be uncomfortable for her to move in a certain way. If her canter has changed that much since you have changed saddles, I would have your coach take a look at the fit, or perhaps find a saddle fitter to evaluate whether or not her new saddle could be the problem.
As far as her "favorite" lead changing, if muscles aren't exercised they weaken. It may simply be a matter of using one side or the other more. Perhaps in building up her left lead, her right lead was not exercised as much and has become the weaker of the two. The best way to fix that is to simply exercise both sides equally. For every right bend, make a left bend, and vice versa.
My horse did the same kind of thing on the lunge (take the wrong lead, try again a couple of times and then get the correct lead). His problem was sheer greenness at the canter and not understanding his leads. He's much
more consistent now after getting him equally strengthened and exercised on both sides at the walk and trot. He's still learning, and one side is definitely weaker than the other at the canter, but he's progressing which is always good.
