I'm in college and had to leave my horse at home. When I went home a week ago (Sept. 3rd) I noticed my horse acting strange-didnt eat his grain, wasn't acting like his usual hungry self. Generally we assumed colic so we put him in a nearby pasture ( I board my horse) to keep an eye out. By the next day we realized it wasn't colic and seemed to be some kind of virus. The vet found a somewhat high temp and gave him some meds, pulled bloodwork and found it was viral. To speed ahead a little, he didn't ever get rid of the fever and stopped drinking so I got a call on the 8th saying that my parents were bringing him up to the vet school. (conveniently the NC State vet school 5 minutes from my dorm). By this point he was wobbly on his feet and started stumbling a little, as well as grinding his teeth. (signs of laminitis). They did ultrasounds to check for ulcers and packed his feet (radiology wasn't available until the next day). The x-rays found nothing, including no laminitis or founder. Next step- nervous system. They did a check yesterday and found no problems there. So now we are having to do research to find out what this could be... have any of you had a similar unexplained experience of this kind???? Any ideas or suggestions would be MUCH appreciated!
