I sent a 2 year old TB colt many years ago to a WP trainer to be backed, and as part of his training sessions, he was tied to one of the large beams in the indoor arena, on rubber mats, while the trainer worked other horses all around him. He was attached by a thick cotton rope that threaded through his halter to a large, flat, thick, padded neck guard/surcingle so if he pulled back, that would take the pressure and not the halter
I guess the first session was spent trying to dig to China and move the arena a few feet :lol: and he soon found out that wasnt going to work too well
From that point onwards, for 2 hours before being worked and for 2 hours afterwards, he stood tied there while the other horses were being worked and in short order, he learned that snoozing and getting some “zzz’s” was the best solution when being tied
I loved working with this trainer and he also mentioned that when he and his wife met up with some of their “English” friends at shows, and wanted to go for a coffee or lunch, the English people had to go and find a groom to hold the horse while they left, or to “watch” the horse if it was left in the trailer. And he said go to a Western show, and even the yearlings will all stand quietly tied in a row to the trailer, and will sleep until someone comes to get them because they have learned that is what they are expected to do
