I have been riding for 6 years and I recently bought my first horse in December. She is an 8 year arab x quarter horse mare who hasn't really done much for 1 and a half years. I know that her old old owners did pony club with her. I have found that she is really unbalanced on the right rein, so much so that she slipped one day and fell onto my foot which I unfortunately broke.
Over the months I have had her I have been lunging her on the right rein to help build up her balance. It has gotten to the stage where she is comfortable cantering on the right rein whilst on the lunge. However when she is ridden and I attempt to canter her she either rushes into a fast trot which I correct or we won't be able to make a full lap of the arena in the canter because she just can't handle the corners. I was wondering if anyone could help me fix this problem.
