Shocking is extremely fast, even his collect canter is fast. When he sees a jump? He's a rocket. I was reading somewhere that horses that like to rush benefit on exercises that encourage them to think instead of being a more "point-shoot" time of deal.
I've been working a lot on his lateral work, but also incorporating low jumps. We've been especially working on our lead changes. I set a jump up against the wall. We jump it (generally no higher then 2ft, but I've done it at 2'9), then I ask him to come back. I complete a 20 meter circle where I am facing the wall. I then ask for a lead change and re-jump the fence. I then repeat on the other side. This sort of thing seems to be working for him.
Do you have any good/original grid patterns or jumping exercises that can improve the mentality of my horse?
