Ok so I have a paint mare she is 18 and I have been trying to 2 years now to get flying lead changes she will get them for about a month and them all of a sudden stop! I tried to only do one each direction only once a week. So I don't think she is tired of them. She also just turns and counter canters around and could really care less. How do I get her to move off of my leg and to be consitant about them? Thanks.
