doesn't matter what kind of gaited horse you have, you want to treat him like a horse first.
walk, gait, trot, lope, gallop if you wish.
of course, being 2, I would stick to LIGHT riding til he's closer to 5 (a horse doesn't mature physically or mentally til 5)
Just train him like all the rest.
the more you do all gaits, the looser his back will be and the easier he'll gait naturally.
Gaited horses are born that way, so nothing you can do will ever change that.
You might get a pace out of a Tenn Walker or a Rocky Mountain.....and that is bad. a pace is one side moving at once. this means the horse's back is locked up. not something you want a horse to practice. yes, there are people who do it, but it doesn't make it right.
So...no, don't do anything different. Stick to a snaffle bit and get all the speeds going well, and the horse will gait better because he's not being unnaturally restricted (not allowing the trot or lope).
