WhatEVER breeds you look at make sure that the horse likes to jump. It's NO FUN to point your horse towards a jump and only YOU end up on the other side, LOL!!
Also you're going to want 16"2hh or a little taller bc you may want to switch from Hunter to Jumper, and shorter horses have problems with the height and width in the upper level shows.
And there is the hammer hitting the nail on the head.
Not all horses from breeds known for jumper are any good for jumping. You really have to just look at the horse. As my grandfather would have told you if you asked him (and I've poste this before somewhre): You want the horse that gets you over the fence every time.
It's the horse, not the breed.
I would have never thought my girls, being 1/2 Friesian, would have jumped anything higher than a fallen log. They'd never jumped anything or seen another horse jump anything. Yet, right after a relocation last year I separated my mare to work with my filly (their pasture has a dividing fence. After 30 min she'd wanted to be on the other side. She tore the top of the fence off (1358 lbs horses can do that), but cleared the ropes. The top rope is 40" up. She was fine though and happily trotted over to push the filly out of the way and get my attention. But then I had to stop and repair a fence.
Later discovered that my filly's sire (he apparently gets around
) has several offspring that compete in jumping (1/2 Friesians....go figure, since Friesians are certainly NOT noted for jumping)
So it comes down to look at the horse. If it you like it, jumps to your satisfaction and you can afford it then you might have the perfect jumping horse for you.
No pictures of my mare jumping (and I hope never to see it again), but here's some pictures I was directed to when I was finding out that these horses are used for jumping. Not that they'll ever win a title, but who am I to judge.
