Even though all the clinches are still in place, she amazingly only removed one piece of hoof wall.
I was reminded of the same thing when looking at the x-ray of my tooth (the one on the left):
As the endodontist said, "you don't need me to see that" - it's split from top to bottom down the middle, in fact all the way into the root. No wonder it hurts - it's surprising it didn't hurt sooner. It can't be saved even with a root canal, so it has to go. I'm lucky it wasn't my jaw that looked like that, and just a tooth. Another dental appointment awaits to remove it.
Our horses are mysterious and powerful creatures with their own special powers and capabilities, different from but not inferior to those of people - and not just in bending steel or splitting teeth! I spend so much time with them it's sometimes easy to forget how amazing they are, how careful we should be in working with them considering their power, and how honored we should be that they allow us to work with them and do things together with them in partnership.
