My horse is a very good all round horse and can jump anything you put in front of her. She is 16.1hh, 16yo American Quarterhorse but when we jump her she takes off about 2-3 strides before the jump even on small jumps, she can jump with ease. She will approach and clear a jump perfectly but then heading to the exact same jump she leaps it approximately 2-3 strides earlier then needed and higher aswell.

There could be several reasons for this, she could be over-cooking her fences due to excitement or pain, assuming we can rule out pain probably the best idea would be to concentrate on flat work over poles for a while, to try to teach her to listen to you & approach her fences correctly. Try the old fave of a line of properly spaced trotting poles & get her trotting happily over these, then raise the last pole to make a small jump. Once she is doing this happily you can change the spacing & work over the poles at canter, also you can try raising different poles (first & last, or first & middle etc), keeping the other poles in place on the ground. Hopefully this will get her concentrating & listening to you, good luck

What she said! poles poles poles!!!

Yeah, same advice I would give. Use trot poles, progress to canter poles after. When starting to put a cross pole up, keep in a nice straight, forward but steady line over a few trot poles and then the jump after. Do this on a few occasions, get used to canter poles as-well then use them in-front of a small jump and slowly reduce amount of poles for each jump and the hopefully will pick it up and jump nicely for you :-)

i fell one day from the horse and fallen with my back and now also its pain has not went so always catch the horse hook with tight hand
