I was always looking for stocked legs, never a stocked sheath haha. The only other time his sheath swelled was when we went to an area heavily infested with greenheads and they all bit the heck out of him before I could get the fly spray. He got so many hives and his sheath swelled that day poor boy. Luckily where we were staying the closest vet was literally 5 minutes up the road.
He had a good lunging session today as I didn't have the time to ride. Also, they've been turned out as much as possible with hay dropped in multiple piles around the fields to promote movement. Swelling only seems just barely there now. I'm just glad it wasn't anything serious.
