Sometimes I have found that to send him you take the 12 ft rope at about the half way or a little more, raise your arm, with the rope and point, while using your other hand to swing the end of the rope. This way you can actually turn his head a little, until he gets the idea, and I swing the rope a little farther back to get him to move. Make sure you have the rope loosely in your hand, so that he can move out and away from you into his circle easily. I would recommend more of a carrot stick than a lunge whip, I just think it works better, but frankly-in the beginning, I hfind it easiest with just the rope. I get all tangled up in fumbling with ropes, strings aand all-it gets ugly! Lol
I do think shortening up just to get him started and direct him more will help.
