Is he trying to lead you at all times, or is it just when he wants something.
Have you tried the premack prinicple? What is something he wants? Start with a short heel in the yard, reward (with something he likes) and gradually increase the time in heel, and length between rewards?
I’m not an expert by any means but those have worked for me.
