ForbiddenHorse, that is right - there is no one in the trailer. And no, it is not winched in, in any way! The horse has to make the decision to go in by itself. There is a constant gentle but persistent pressure from the lunge line (which can be yielded instantly if necessary for safety of course) keeping the horse looking towards the inside of the trailer. As the horse decides to take each step forward, the slack is taken up so that the pressure remains gentle but persistent.
Very interesting, thank you. I didn't mean they were being winched in, but it would 'look' like that from a distance. Just trying to get the idea of how it would work was all. May be worth trying when I'm on my own!
