Okay, it's making sense now. When you say it is not a trot, that makes me feel much better. Basically, since there is no suspension, with one foot on the ground all at times, there is no pounding. And the neck doesn't bother them?
No, I have never ridden a gaited horse. It looks like you would just be sliding along on your butt with your legs out. Ha! I can see how this might be appealing since sometimes my back is killing me after riding my horse's 2-beat quick beated trot.
Do they naturally know how to do it 4-beat gait or do you have to train them?
