Many years ago my instructor had a young OTTB who didn’t know there was a world outside of the barn or track! When teaching him to go on the trails he would jig and carry on the entire way back home. She planned a really long day…took him out early on a nice long quiet ride and then on the way home, every time he jigged, she just turned him around and went back out on the trail and away from home! She said it took a few hours that one day, but he never jigged again!
Hope that helps!
