So what is next in his training? Right now when I see him I do the following:
Practice for youngster in lead (leading with halter and trotting in hand)
Ride at a walk around the field. We turn (eventually) and stop (well) as we go randomly in the pasture. Sometimes we go out on the dirt road, and a straight line NEVER happens, but I know that's normal.
The one thing I was thinking was yielding to leg pressure. Right now any pressure with my legs or feet means "go faster" to him. Partly because he is bored with the walk and partly because he doesn't know any better. How can I teach him to move 'over' and turn better with my legs? Is that next or am I missing something?
