He's almost through the first week of treatment. It's taking its toll on him, he's not a happy pony right now, lots of coughing and very irritated airways :( I hope it'll turn around soon.

At least it's spring, the weather's nice and warm but not hot, and he's on grass pasture approx 5 hours/day along with 2 other horses from the barn. Anytime one of us three owners come out to get them from the regular turnout all three horses come galopping and neighing to the gate - methinks they like their grass ;)
