Yeah, I'm just looking to do the little stuff for now.
What do you mean the way they move? he's no WP but no Waradmiral either...
Like my horse for example. He'll never be a high-level dressage horse because he doesn't have fancier action, he moves flat-kneed. He moves how a western pleasure horse should.
I'm not saying speed, I'm saying his movements. If you posted a video, it would be easier to judge.
Out in the field, if a horse runs up to fences and rolls back and stops really well, they're naturally good at doing reining. No matter what they look like.
When my horse is out in the field, he lopes along, head down and VERY slowly (I can run faster) which means he's just naturally good at western pleasure.
If you can get your guy to extend his legs at a trot and bring his knees up over a jump there's no reason he can't do hunter/jumper classes. Just because he's not the typical build, doesn't mean he can't do it.
Also, just because he naturally moves a certain way doesn't mean he can't do something else either. He may not excel at it, but it doesn't mean he can't!
But really, unless he has some very messed up conformation (which I doubt) then he won't have a problem moving english or going over jumps. Will you make it to the Olympic level? Probably not, but he can still do it!
Free-lunge him over some jumps, ask him to extend his trot. If he does it, then I don't see why you wouldn't be able to while riding him.
