I fail to understand this mentality entirely. How is what she is doing any different then what anyone else does? This is HER passion. Training a horse to jump is nothing but a circus trick - unless you hit Grand Prix, you dish out whackloads of money to win nothing but a piece of ribbon. Trick training has just as much professional merit as any discipline - she could be hired by rodeos as a show, she could use her tricks to evolve into a more dependable mount, she could use her skill as a trainer to teach things like tricks or even help people develop better manners in their horses.I saw this a while ago. If you're not a professional, teaching your horse to rear is stupid. Most people consider it a dangerous vice and it pretty much destroys the horse's marketablility if you ever had to sell it. I know I would never buy a horse that rears, either as a vice or on command. I would certainly never put a little kid on a horse like that.
It's just a bunch of circus tricks. I don't see why I would ever need my horse to do most of that stuff. She needs a bigger pony, too.
