Leadrope for a Bad Leader
Someone before me taught the pony I'm working with that backing up on the ground was an acceptable way of getting out of doing things. He's a truck of a pony and sometimes he's awesome and other times he either runs backwards or tries to run over you (not maliciously, he just gets too close). He also chews leadropes to no end.
What kind of leadrope should I be using to keep his attention? Chains don't work, he backs up even more and I don't want to start a rearing problem by putting him near a wall. He's a kids pony so he has to be good.
