Buddy gets Zum to canter around him to the left by swinging the rope he carries towards Zum’s withers. If Zum doesn’t move as fast as Buddy wants, he throws his rope towards Zum’s forequarters with more energy. If Zum resists, Buddy matches Zum’s resistance. When Zum canters, Buddy quits swinging the rope. Buddy tells me that Zum is not lazy. Zum just doesn’t always want to do what Buddy asks.
