What makes a horse a (naturally) rough ride? I rode this one QH and I about died. His jog was very bump (like riding a jackhammer) and his lope felt like if you floored it going over a speed bump (in a car). He was sound and well trained (he used to show), so that's not the problem. Other horse's trots (English) felt lie they were floating and their canter very free-rolling (this was on an Arabian). I have ridden other QH with a smoother gait, so it is not the breed. So, what makes a horse a rough ride? Conformation, yeah. But what conformation makes a rough ride?
