I have always enjoyed horses and would like to train one.  Do you have any experience?
I do! What are you looking to train your horse to do? Horses are usually trained to do something specific, like movie stunts, police work, or just general riding.
I want a horse that can jump well!
Horses can definitely do this! It's important to make sure that you're gentle with the horse when training it, making sure not to use techniques that may be considered cruel to the horse.
Understood.  What is the best kind of horse to train?
Any type of domesticated horse can be taught to jump There are feral horses that live in the wild that would be much more difficult to train.
Interesting!  I didn't know there were still any wild horses!
Yep! All horses were wild until humans started domesticating them around 4000 BC.
