Well, again, I don’t hard tie horses that will panic and sit back, so we have come full circle. And, yes, cheap rope halters absolutely will stretch under high pressure. The throat knot will loosen and/or come untied if it is tied incorrectly, which is incredibly common. High quality ones, properly fitted and tied, do not.
Sorry, but I’ve been around a lot of different types of horses, management systems, and perspectives over the decades. I have made well-informed, calculated evaluations of what tools are safest in my experience. I know how many terrible accidents and injuries - horse and human - I have seen caused by breakable equipment. Having been involved in teaching at the university level for over a decade, I’m also highly risk averse. I have chosen my management/training practices, equipment, and bloodlines to deliberately minimize risk. There is nothing we can do with horses that is zero risk, but we can hedge our bets.
Don’t use rope halters if you don’t want to. But do not paint them as “dangerous” as a whole just because you have seen them used improperly.
And, I find it laughable that you claim to know what the inside of my trailer looks like without having ever seen it. COTH hubris at its highest, per usual.
With that, I have work to do. Hopefully the OP has picked up some useful tips from this thread and hasn’t been scared off by some of the posts.
