Wow, there is some pretty scary stuff here! I guess my greatest fear is a head injury, or an injury that would prohibit me from riding and doing other physical activities. Also, would not be able to tolerate seeing a horse injured and in pain. Last fall my mare Nessie colicked. I know, no big deal, but I can't handle those kinds of things very well. I arrived on a Sunday afternoon to find her covered in mud, her mane and everything, writhing on the ground. She wasn't even mine then, I was still leasing her. I thought I was losing her. It took a couple of hours for her owner, BM, and another hour for the vet to get there. I helped with the intubation, and she was OK the next day. Can't tell you what that experience did to me... I felt the affect for days. It was then that I knew for sure that she was my horse.
