>>509400004horses with severe leg injuries will never be able to recover, it is a legit game over situation. biologically in the history of evolution a horse that cant stand or walk is so fucked that most of the parts involved in the body literally never bothered creating an instinctual design for how to promote healing. At best you are just going to put them in a frame that supports their weight and keeps them upright, and this allows them to continue eating food that you bring to them, for the rest of their life until they expire. That is hospice, not saving them.
