My Horse Will like act all nice and we will get into the canter and approach the jump and then he will Stop VERY Fast ,Turns , and Quick stops the Jump . It is really annoying because I end up having to go around like 8 times before he actually will do it. What should I do?
Either he's overfaced or he's putting you on. You can check both with the same exercise. Setup up a baby jump or crossrail. Take him straight to it. If he sails over it with no issues, he's probably either lost confidence in the larger jumps or possibly having pain with the bigger jumping effort. If he still balks at the little crossrail, it's time to go back to basics. Make sure your driving him squarely to the fence and not giving him any escape route. If he does try to bail out, don't let him turn away from the jump. If you let him complete a circle, he has succeeded in turning away from the fence. Instead stop him, back him up, side pass, whatever manuever you need to get him back in front of the fence again. Then make him go over it, period. Keep doing it until he gets the idea that his new runout strategy isn't going to work. Good luck.
The Jump was a 1.5 Feet.. It Was Small and it was vertical. He has been jumping for 7 years.. but I have only been jumping for 2.... But He jumps in when I free jump him or lunge him at it... its only when I ride him.
Sounds like a pain issue to me since he's jumped before - for years - and it sounds like he did so without any major issues. I knew a horse that went through this and between his back being out from the rider slamming on his back, he started charging the fences and then hard stopping them. She used spurs and added a bigger bit which (shocker) only made the issue worse....
Check saddle fit and back pain, and go back to smaller stuff - ground poles, flat work, and do so in as mild a bit as possible. W/t/c ground poles before making them teeny tiny verts or x=rails and go from there. And take it slow. Pain or not, you're definitely asking him to do something that's scary to him and outside his current realm of confidence, no matter how petty it may seem to you. It could be confidence alone, or it could be a pain issue that's making him afraid to/unsure of jumping b/c landing causes pain.
