Yes, I have done that in a single session, but If you don’t have enough time, it’s OK to quit when you have gone a bit farther then the time before. I would then get off of the horse while away from the barn and lead him back.day. Takes a lot of patience to stick with it. If you have an excitable horse, you need to be “ho-hum” about the whole thing. Don’t make a big deal about it, just stick to your program of going away and coming back, going away and coming back. Once you’ve been successful, the next time will be easier. Eventually, you will be able to ride away without all the rigmarole. Am curious to see how this works for you.
