I made it out to the barn yesterday and though the world was icy and encased in frozen water, my horses were happy to see me and feeling silly.
Renny is not having too much trouble with swelling, but I could see that the tip of his sack was a bit swollen and tender and a bit discolored. So, his bruising and tenderness is descending to the end of his bag. But at least the incision looks pretty good and clear or bloody liquid is the only discharge.
