Woah, woah, wait. You've euthed one horse, are thinking about euthing another, and you just go ahead right away to look at another experiment for you? Please girl, stop. Sell your current horses or give them away, get a nice, older lesson horse for YOU to learn on. Once you know enough and actually have a good financial stepping stone then you may get this horse and not ruin it, please. You don't need to keep getting these young OTTB thoroughbreds for yourself.
