So we were playing with the appaloosa gelding at my barn who is about 16hh and built like a warmblood. And I'm pretty sure in another life he must have been a 3 day eventer, because he throws random dressage moves into his daily antics, and can jump like his tail's on fire.
Just the other day we were lunging him and I decided to ask him to jump. I've only jumped him like this once before, and from the conversations I had with one of his previous owner, he did a little bit at his old home but apparently plowed over more jumps than he cleared.
But we tossed a pole in front of the jump where we suspected he should take off to clear the jump and welll... he cleared it. So we put the jump higher... and he cleared it again. And before we knew it he was jumping higher than any other horse I've ever worked with - I work at a dude ranch so I know that doesn't mean much but I was still impressed.
So anyways, we went up to 3 feet 11 inches... and actually once he jumped just over that. And here's the kicker, the brat wouldn't get into a canter for the jumps... he was staying at a speedy trot.
So I wonder, for a horse with no real previous training, and nothing really in the way of muscle tone, how high do you think he could go with propper training and muscle tone?
