Cross-cantering while lunging
So my horse has this nasty habit of cross cantering while lunging, only on the right lead. Under saddle he does 10m canter circles canter-walk transitions and the beginnings of counter canter.
He will cross canter while lunging on a 20m circle with and without bit, saddle, side reins, etc.
Because I'm in exams and school and don't get much time to ride, he is getting a lot more lunge workouts from my mother. She has just been bringing him back down to trot and up to canter again every time he cross canters.
I'm just wondering if anyone has had a similar problems or any tips/tricks to fix it, of if we're on the right path.
(PS, he has had a vet look at him, and does regularly.)
