HORSE UPDATE:
We have never had a horse collick and Pop (is in his 70s) & has had horses his whole life so this had him really worried too!
DH & his brother walked her for over 3 hours non-stop until the vet could get there!
The vet said taking everything into consideration, the usual treatment of tube & mineral oil would not work. It was not making it far enough to come out the back end, so the oil would do no good, or something along those lines.... and since horses don't throw up - we drained a lot out with the tube.
She is feeling better, but not where she should be. After the first shot, Vet said she should have been back to normal within couple of hours. she wasn't & still isn't herself but is feeling better - eating grass & hay, but not much feed.
