Wow. Those are quite the images! Thank you for sharing. I'm glad that Tinker is going to be okay. Talk about scary!!
We lost a horse from sand colic. He was just never quite right after the first time and eventually got a bad enough case that there was nothing to be done (couldn't afford the surgery). All my horses get their weekly doses of Fibersyll, but it's nothing but sand where I live, so you always have to keep an eye out for it to show up.
