I've recently decided to work with a 3 year old Belgian/Morgan gelding that has been sitting in my RI's pasture since he was weaned (nobody had time for him). He's been trained to lead and cross tie, but will only stand in the cross ties for so long, than he starts to rear and throw a fit. When someone leaves the cross ties, he tries to follow. I picked up his feet today, handled his ears, and got him used to a saddle pad and a girth, but other than that he's clueless as to what you want him to do.
I tried to lunge him today, and we mastered lunging at the walk, but even when I lead him he won't trot. What else can I do to train him? And how do I get him to trot? He's probably going to end up being a western horse if that helps any.
