I have a 5 week old fainter buckling that's had a bit of a cough the last 5-6 days. It was just a little hack you'd here once in a while when around him, but today, he coughed so bad, he fainted himself. At that exact moment, the vet pulled in to draw blood on a horse for a coggins test and I told him what just happened, so he checked him out. Said he seems healthy, no rattly lungs, no nasal discharge (never has been) and he eats and plays fine. His cough today is more like when you get a cold and cough up some of that wonderful goop. It's really freakin' cold in Wisconsin right now, with really bad extremes, it was 60 a few weeks ago, then cold teens, then up to 50 on Sunday, now we're below zero again at night and during the day too with windchill. GRRRR... He's not locked in a stuffy barn either, they have well bedded calf hutches and a paddock to roam in. The other 3 kids and the 3 does out there have no problems at all. Any ideas?
