It's certainly gotten worse in the past couple of years, he doesn't cough a whole lot (he's currently just getting cough free but he was given a round of steroid injections last month that seemed to help somewhat, but not as much as I was hoping). He's usually not terrible in the summer but he's been pretty bad this year, although I'm fairly sure it's because the hay where I'm boarding him is terrible, extremely dry and probably dusty. I think if he was in an environment where the owners were able to ensure he was getting soaked hay and steamed hay in the winter he would improve drastically. This past winter I had him at a different stable, and despite being inside most nights he did incredibly well, he didn't need medication at all and I almost forgot he even had breathing issues. The hay there was wayyy better, but some extenuating circumstances (with humans) forced me to leave. He's been shown at Trillium level (which is akin to regional level) in the ribbons, but I've only been able to show him myself at one of those shows, where we received clear round and 3rd place in the two courses I took him in. He did well with the girl that was leasing him, but she hadnt quite gotten the feel for him yet and then decided to stop leasing him - she took him in two trillum shows with a couple of lower placing ribbons. He's done brillantly at local shows with me, grand champion in the jumpers at a couple of them when I used to be able to go. I'm hoping to do some schooling shows in the fall to show him off a little to potential buyers. But when he's bad, he's really bad - to the point where he can only be ridden lightly for 20 minutes, if at all. But like I said, I think a big issue right now is the hay, because, though he wasn't great at the old place last summer he wasn't as bad as he's been here, and they weren't soaking the hay at the old place either. But I full heartedly believe that he could still be shown if the proper precautions were taken.
