You can definitely tell he's a pony looking at his canter stride, lol. He's a stellar little jumper, the only thing I can thing of is some flatwork schooling to keep him steadier coming at the jumps and to orevent him from cross-cantering. The rider really has to grab his face, so working a bit on that can really help. Otherwise you have to grab his face and drop him over the jump, then grab him again. What a cute little pony though!
Yes he has a very short stride, and he is actually known for it... haha. I know if appears he pulls a lot but he is actually a very easy ride (bouncy) but does not pull. He has a very unorthodox way of going and I get that response all the time, til they see the pony go then they see it.
