Well, I was really surprised. I was going to train another horse to load in the trailer. I put them in the round pen and they immediately went to inspect it so I opened the door and went to get my handi-stick. When I came back they were already loaded and stayed inside for about 30 minutes. Don't figure. She is four and only loaded when a yearling one time. They never seize to amaze me. Then we just unloaded her and shut it up. Will be working with a couple more tomorrow. It would be great if the all did that. Good luck on your endeavor. Again, I still strongly that food should only be used as a reward not an incentive. Keep us posted on your training.
