That being said: on Friday evening when I went out to feed him I noticed that he was swallowing weird. A few minutes later when I came back to check if he was done he was coughing and started to have mucus/food come though his nose and mouth. This especially scared me because I know that horses can't puke. (I've been around horses my entire life and know quite a lot about them). I called my vet and he immediately diagnosed it as choking. He told me to put Billy in the barn in a stall with no food and plenty of water until he was able to clear the obstruction on his own. After 2 days of stress, mucus, dehydration and praying that he'd make it through this Billy is now breathing normal again (but still having some issues breathing). He finally started to drink water again and is now eating soaked food (hay, grain, ect).
Do any of you have additional advice/precautions to take with him from now on?
I've read a lot of articles and such on horse choke but it's always nice to get "real" people's opinions. :)
