My dad is a physical anthropologist and every time my horse does something to damage himself and I put another however many hundreds or thousands of dollars on my credit card (my choice, wouldn’t change it), his comment is always that horses only continue to exist because of humans and our intervention, because evolution would’ve done away with them otherwise.
I’m not sure that I wholly agree with him on that, but given his accurate assessment of the propensity of horses to break if you so much as look at them wrong (or don’t look at them for half a second), this is just… My trainer ran a horse from BN to the 5* level and then stepped him down and sold him on to an amateur to be spoiled and teach her the ropes at Training level because (trainer’s words) he didn’t owe her anything at that point and she wanted to give him the retirement he deserved. He had to be euthanized after a pasture accident this year. In my last training situation we lost a lesson horse to colic after trying everything to help him (I’m the one who noticed it and hand-walked him for three hours and then loaded him on the trailer to go to the emergency clinic after our regular vet couldn’t help him, and six years later I still wonder if I could’ve done more for him). I personally know someone who also lost a horse to a broken leg from a pasture accident (on solo turnout). I don’t even want to list all of the bad luck that other people I know have experienced.
There are always, always, always going to be discussions to be had about how we make eventing safer, but every single one of us who engages in any horse sport has made the active decision to be involved with animals that have an unfortunately high chance of breaking themselves whether we work with them or not. I’m not going to say that we shouldn’t try to figure out what went wrong when tragedies like the ones in this thread happen or shouldn’t draw personal lines in the sand about what we’re willing to do—I refuse to run my former favorite unaffiliated event anymore since they put a fence on course that I don’t feel is safe or appropriate and I refuse to risk my horse or myself attempting it—but we can have those discussions and be respectful of people who are hurt and grieving at the same time. I truly don’t believe that the two are mutually exclusive and it’s counterproductive to act like they are.
