I typically just put my horse in the round pen and let him just run out any excess energy he might have built up on the days that I don't ride him. But the shows I go to, usually don't have a round pen to do that. So I've began training him to lunge. I've trained two other horses how to lunge but I've never had to deal with the issue that presents itself to me with him. He is responsive with the cues I give him for walk, trot, canter, slow. But he has the issue of changing direction by turning away from me, So then the lunge line is on the opposite side of his head, which makes it come up over his neck. Which of course, is a dangerous situation.
On some days he will change direction out of no where while he's cantering or trotting, and just take off in the other direction. I don't mind if he's turning IN and changing, but he turns toward the outside.
So as of late I've just been putting him on the lunge and having him walk in circles. If he starts acting stupid, then I make him move his feet. Is this a good way to get him out of the habit? Some other way?
