Trust is the last thing we receive from our horses, and possibly the last thing we may notice. Most people think they have their horses' trust, but the fact of the matter is, horses have learned to tolerate our everyday dealings with them. You can't train trust into them, even doing the exercise of JOIN UP. The horse only becomes conditioned to our presences, requests, and techniques thru our training patterns. The horse only displays to us the response he thinks you wanted with that request or cue. He could have guessed right only by luck or chance. When the cue of join up is repeated over and over again, the horse learns the proper response you want by doing the same thing, approaching us when we have our backs turned, us ignoring the horses' presence. Don't mistake it for bonding or a trusting relationship. It is a conditioned response to a certain cue.
