Hey, I'm 14 too. It's okay, he should be fine now that he is eating again. Just make sure he's getting plenty of water. I've been through alot of problems with my pony Gizmo. He's coliced on us many times and once he ended up spending about a week and a half in a horse hospital. I just know from experience that no eating is a bad sign. It may not have been a tooth now that he is eating again.. but when was the last time his teeth were floated? If it wasn't in the past year, it's probably about time. And my other horse "gulps" his food so he's had problems with choke several times. If your horse eats really fast that might have been an issue too. One last possible thing, illergic reaction maybe? He could have gotten into something that may have irritated his mouth. That may have been why he wasn't eating. I think that can clear up quickly too. Also his mouth probably was sore.. if someone was yanking on it especially. Well I hope he gets better, best of luck!
