I never have an actual buy-back agreement written up, but people that buy horses from us KNOW we will take them back under any circumstance. We have had horses come back to us to be re-homed quite a few times. Most people keep in contact with us over the years. We had two horses with issues. One came back FIVE times. The other came back four times before finding a home. I have a horse right now that has a signed buy back contract on it. If I decided to sell him, he would NOT be going back to the old owner. I would not even call her to let her know I was selling him.
