Loading a difficult horse with Michael Peace

This a rising 5 year old Hanovarian dressage horse who didn't want to load into the truck. She's previously been trained with a Monty Roberts pressure halter and learned to pull through it. I was called in because not only was she now difficult to load but if you did manage to get her in she wouldn't turn to be tied up on the left hand side of the truck. Attempts to turn her to the left caused her to launch herself off the truck and down the ramp. I was with her for just over an hour but had her loading happily after the first half an hour.
