Is it ethical to put down a pasture sound, light riding only horse? I know would rather see the horse put down then passed on to someone who might not care for it properly. However I think if a horse is yours, you're responsible for it until you ensure it gets a good home or it could no longer can enjoy life. I guess what I am asking, is it ethical to put down a horse that you can no longer ride or use like you used to. Would you euthanize a horse because it has a career ending condition but still pasture sound?
