Bit was attached to bridle with the leather tie type attachment and those didn’t break either.
I guess that is what I am asking, where is that point where leather is sturdy enough to hold up to everyday use, but in a panic situation when a lot of pressure is in play, it breaks.[/QUOTE]
Unfortunately, you can’t “plan in” a breaking point on leather. This is because the weakened leather tack will break when not expected, get you hurt. You were not in a situation where you wanted horse to “get free” that time! But he did, now is learning bad habits.
We do a lot of Driving Horse stuff, just did a huge discussion about breaking leather or harness, cutting them free in a downed horse situation. It was about 99% on the side of NO BREAK tack. Reason is horse feels ANY bit of give in a situation and he will fight hard to get loose. Horse down, restrained by tack, tends to give up and wait to be helped.
Could be the Driving training, learning the patience and acceptance of so much restriction, but they seem to usually WAIT for help if there is not give in the tack. Seen it quite a few times, various breeds, situations of excitement. Waiting until ASKED to move, horse is less likely to get truly hurt or hurt YOU helping him, doesn’t fight while down or waiting. Seldom any need to actually CUT harness either, you can unbuckle to release parts, then ask horse to get up and be lead QUIETLY away.
John Lyons was among the first BN Trainer to WORK at teaching “give to pressure” not explode. Used the Give in many steps of his training methods, probably saved a lot of horses damage, when trained that way.
We spend a LOT of time with our horses teaching them to “give to pressure” and making sure they TOTALLY understand how to get away from that sudden pressure that might surprise them. Starts before they ever even get tied, as young babies. They never learn that fighting will let them “win” by breaking tack. That will just escalate, he WILL fight harder next time.
OP, not to be harsh, but maybe you need to back up, work with this horse on giving to pressure for a while. If startled his first response is NOT to throw head and race backwards, get away, then get tangled, while you are hoping tack breaks. And I think since his first experience didn’t go so well, he will PROBABLY do it again, while worried about being hurt the next time around. So best be prepared for when it happens, even if he has no outside “reason” to act silly. He will likely set himself off with the worry, not need a reason.
