HI Marlene, I agree with the others. This seems really risky to
me. I go along with the "You break it, you bought it" for the full price,
the vet pre-purchase exam, insurance on the contract, a sponsor you trust
riding with her, etc. And the other thing I would check into is what
is your liability if the child gets hurt by your horse during the ride or
your horse hurts someone else while the horse is in her care. And I would
want her to feed, supplement and lyte, her however you want her to. Even
under the best of situations, horses manage to hurt themselves. I wish were
weren't in such a litigious society but we are. Good luck.
