EMS, proud of you for being concerned with her AFTER the sale. Kudos to you for wanting to make sure she can have the very best experience possible with what the new owners can provide. It will be different and will be new, but they would have to mess up badly in order for things to go south - sounds like they have good intentions. For what it's worth, I've always had better results with training young horses (even long yearlings) when they first arrive here. They don't know anyone, they don't know the rules, and show them even the teeniest amount of kindness and they are in your pocket from then on. So there is a possibility she could respond really well and it might even work out for the better. Stay optimistic!
