This was a very tough one for Suzette. I had to go through it more than a couple dozen times to get her calmed down. She freaked out and took off like a rocket the first time we attempted it. There are big pine bows on the other side to create movement after the horse steps off the bridge - and since she is so short, my feet would always bump one of the barrels on each side, creating even more movement. Combine the two moving obstacles and the deep booming sounds of hooves going over the bridge, and it was unnerving for her. But, we did it. Over, and over, and over, and over, and over, and over again......until it wasn't an issue anymore.
Octopelle had a hard time with the ground poles, which I thought was weird. I have them setup in the pasture to practice all the time and he goes over them great - but we were in a strange place and his attention was on all the other horses and scarey objects, so he kept tripping over the poles like a total dork. We kept practicing until he had full concentration and picked his feet up.
