Question

What do you do to make your horse gallop?

Answer 1

once in a canter, stand up and lean forward in your stirrups, make clicking noises with your tongue, squeeze with your thighs, and kick him like you would do to get him going in a canter.  Just lean forward in a 2-point position, and maybe even tighten the reins. Anything to encourage a faster pace.

Answer 2

I've got my horse to where I cue him to change, to get him to gallop I just suck my lips twice. My horse won't gallop either if I don't let him have his head, so I have to lighten up on the reins.
