I recently (2 months about) got a new horse. He is a six-year-old appendix with too much energy for his own good! He is very good in a walk and trot and I have done lots of groundwork with him already. As soon as I push him into a lope, he takes off like a bullet. He will not slow down no matter how much I talk to him and try to slow him down, all my strength cant slow him down. If I do get him to slow down, he throws a fit and bucks. I don't know what to do to teach him to slowwww himself down. I have tried groundwork and lunging... he will slow down there but as soon as it's in the saddle he feels the need to take off. Help! I have tried everything I know how to do. Multiple trainers have tried to help me as well and they can't get him under. He's so good with everything else except for loping. Any advice is greatly appreciated!!
