I'm so sorry to hear this, what a horrible thing to happen. I'll be thinking of you. I only have two minis right now and several big horses, but I wanted to respond to a question in this thread. We vaccinate our horses yearly for tetanus, but if any of them get a serious injury, especially a puncture wound, they get a tetanus booster. We had a yearling run into a fence and pull all the skin off of his chest. He had his tetanus vaccination about 30 days before that, but the vet said to give him a booster anyway. I hope that answers that question, even with a vaccination, they need a booster if there's a serious wound or a pucture. Also, puncture wounds can be very difficult to see. We have these trees around here with huge thorns on them. When I talked to the vet about what to do if one of my horses stepped on one, he said NOT TO REMOVE THE THORN because the sole of the hoof will close over the puncture and it won't be able to be flushed. Just to call him immediately. Please keep us updated.....
