I am so sorry to hear this. It reminds me of a girl whose horse slipped in a trailer and was severely injured.Be carful, We have one of these that is made just for minis and almost killed a horse in it. We had everthing right short ties, non slip floor, ( a wet wood floor can be very slippery.). the horse hurt her head, cut leg to the bone ended up on her back, and in try tp keep her from getting hurt I tore up a hand pretty good. If you have a calm horse that will stand for anything these are great, other wise I wouldn't use one. I tore ours down never to be used again.
