Yes. Unfortunately, I didn't bring video, but I have video of all of this process.
Yes, that determines the pallet size. The pallet size for horses in stalls is the same pallet size as the loose hauled horses, but it has to be able to fit on the pallet mover. It takes them out to the airport. They go on the lift or the loader. That lifts them up. It rolls them onto the airplane and then rolls them down into cargo. I'm happy to share pictures and video.
