Hi i know i am replying to an old post but it currently applies to me and a young horse i am having similar problems with. Now this may sound a stupid point/comment to make if as the person says her horse pulling to the right would you not feel the pull in the left rein, as i do and the right rein feels as if not really any use?? Therefore the correction doesnt make sense to me. My horse is not leaning, he is pulling sideways, he seems to have a curve from tail to his ears. Any bit of advice would be appreciated
