Need help with a training a solid WOAH and Ground Tie
I'm working with an rescued auction horse. He's a grade/quarter horse build, gelding. He's generally a good boy, but he has a "wandering woah." When I ask for a "woah" he stops well, but then starts to creep towards me, one step at a time, same with ground tying.
I've tried asking for a woah, &/or asking to "stand". Praising when he stands quietly and when he walks off, then sending him away, moving his feet and directions. This has worked pretty well and he's 90% there. He stops and listens very well, but then he'll make a minor step to balance himself or to stand square, and then he'll do it again, balancing his other side, but the foot is maybe 3 inches in front of where he was before. Then he'll stand for a full minute or two, and then do it again, rebalance, but 3" in front of where it was before, and slowly he wander toward me.
He's stopping on a dime and I'm fine with letting him re-ballencing himself, but where do I draw the line? How do I get him the last 10% of the way; to stand still, and not wander step by step when I ask to woah or stand.
Thanks in advance!
