I saw my first horse put down when I was younger than she is. The second I was about her age and it was far out in the country, the horse was injured badly and there was no way anyone was going to let it suffer while they waited for a vet....it was not pretty, to say the least. I'm going to repeat what I said - you need to prepare her. For everything. What, exactly, is going to happen. That they will (most likely) do it by the hole that's already prepared, that she may not just lie still, what machinery they will use to get her in the hole, etc. It's not going to be an easy conversation, but it will give her the honest truth so that she can be prepared and make the best decision for herself. She may decide to be home but to say goodbye beforehand and not be out there when they put her down. Just being close may be enough for her. It will be hard no matter which choice she makes, but I have to agree with the poster who said it's a part of life and a part of taking care of your loved animals. I can tell you from experience that I have a cousin who was shielded from everything 'bad' or sorrowful as a child, not just the events, but the details, being told anything specific on how/why/when/where, what decisions were made and why........then she grew up and has NO IDEA what to do in serious situations. She just falls apart. She's having to learn some hard lessons now (and being punished financially as well as emotionally) for things that, IMO, she should have learned a lot earlier thru life experiences.
