I say too... Depends on horse. My first horse was a runner/bolter, I got fed up and more or less TRIED to run him into the dirt... Problem... He was like the energizer bunny. Didn't fix anything. BUT... What I did find out, was that if I gave him some "running time" every time we went out, he was much better behaved, quit trying to haul *** everywhere cause he knew he'd be allowed at some point. And by letting him go- I mean, I'd really just let go and let him have at it for a bit, then collect him up and carry on about our business.
