I am currently leasing a quarter horse mare. I have been working with her for a while on groundwork exercises. She is already mainly broke. The problem is when I ask her to lope, the first time I ask her she responds but then after loping once around the arena she will stop and when I ask her to go forward again and pick up the lope she refuses and either starts to back up or will not move at all.
I have tried keeping pressure on her and using a crop but have not gotten a good response.
How can I make her enjoy loping?
