Yeah, I’d be disturbed too.

There are so many things that we subject our horses to that, when considered beyond our familiar context, seem at best absurd and at worst maniacal. I am going to go out on a limb and say that burning hot steel into their feet probably counts. Ditto for ripping their hair out by the roots.
*Note: I am all about shoes. My horses wear them. I am NOT knocking shoeing. I am simply noting that it sounds a little sketchy when described out of context. 😉
