my question is this - if you feel that your older retired horse deserves to live out his days in peace even though he can't be ridden, who's responsibility is it to pay for that? Yours or the rescues? And while if we/you can find a pasture companion home for that horse, then it's a win-win, yes, who is responsible for the cost and care of the horse until that home is found? The individual or the rescue?
I personally have to have a purpose for every critter I have. I am not against slaughter, putting my critter down, if I can re home than Ill try to rehome. I just don't have the land and resources to keep a critter that doesnt.
