My name is Megan and I have had my horse for almost a year. He is a Quarter horse/ Throughbread 16.3h and about 18. I was wondering what you can do to get your horse to back up while you are riding them. When I am on the ground he will back up fine but as soon as I hop on top he will not back up. I have had many different people ride him varying in expierance and even one of the best people I know has a hard time backing him up. What can I do to Get my horse to back up?

Thx Megan
