I happen to own a horse that was injured as a foal in a halter-gone-wrong incident…some sharp individual turned his foals out in chainlink fence paddocks with halters, one of the barn staff found the filly hanging from the fence when they went to feed in the morning (I found this out about a year after I had purchased her). My mare’s whole head is, for lack of a better term, wonky. There’s obvious remodelling where injured facial structures healed from this incident. She’s very sensitive to poll and nose pressure and absolutely cannot tolerate a hackamore.
So yes, it’s entirely possible for a horse to injure itself from pulling back when tied (or while their head is attached to something). Just because you can’t see the damage being done by a horse struggling against a halter, doesn’t mean there isn’t any.[/QUOTE]
You’re missing the forest for the trees. Foals in turnout in non-breakaway halters is totally different. They haven’t been taught to yield to pressure yet.
And of course damage could occur if a horse really sets back. I’ve also seen a horse break their neck flipping when the breakaway halter broke. I’ve also known a horse that was killed running into a car on the highway after it broke loose from crossties. I’ve seen chaos occur at endurance rides when horses weren’t secured properly in camp. Etc and so on. Really it’s pick your poison. I choose to spend the time teaching them to give to pressure so they tie hard because it suits my purposes.
