Teaching Pony to Follow Ball

We are teaching the pony to follow the ball, with clicker training. At first he would not follow it alone, we had to walk beside him. He is a lead-line pony, so that may be ingrained from his training. After a little practice, he would take a few steps to follow the ball alone. We are working on extended his thread, so that he will go out and away a little further as we progress. He is at liberty, the gate is open, he can leave at any time. When we get good consistency at length of travel, we will add a little speed to it. It will be fun to see him trot to the ball!
