Sure, I have one little nightmare for you that comes to mind. I live quite far away from veterinary assistance, and it is limited at the best of times. And I can not ship horses in snow, 2 wheel drive truck, and a steep driveway. This is a reality that we accepted when we moved here.
I had some minor belly surgery a few years ago, hernia repair, day surgery. The sides of my body wall were sewn back together, and I was sent home. The day after I came home, we went on a little trip to town, to the post office to pick up mail, gone for 20 minutes, a little outing for me. When we came home again, drove down the driveway past the paddock, the broodmare was stuck under the wire fence, fighting. With the fighting, she was ripping more and more of her hock open. It was February, and it was -25C with snow. The DH said to me, “You are NOT going out there, to pull that mare out of the fence”. We both got out of the vehicle, and approached the situation for a closer look. He said he was going to go call some neighbours to help. As he sprinted up to the house to make the call, I realized that the mare was fighting on a regular rhythm. The electric wire (to encourage horses to stay away from the dam fence) was touching the fence somewhere, and she was fighting as she was receiving the regular shock. I yelled for him to come back, and shut the ticker box OFF! He did, and she quit fighting, lay still. The neighbours arrived, and we cut the fence apart, and got the mare up.
Her hock was “hamburger”. You could see the tendons laid bare, and moving. I didn’t think it was cut into the joint capsule, but the gaskin and front of the hock was really bad. Blood everywhere, ragged bits of muscle hanging out. The neighbour (being helpful) picked up the rest of the water bucket (NOT clean), and threw that onto the wound. (NOOOOOOOO!). Too late, it was done. No running water in hoses. No vet available. No ability to ship to a vet. And me not really very functional to do much of the work, and not needing to be kicked right at that moment either.
So I put her on penicillin and bute injections, which I keep on hand. And left it open. And she recovered. It healed up really well actually, came sound on it, left a small scar on the front of her hock. But that day was a nightmare day for everyone.
