Tristan's wound is definitely starting to turn into hoof material - it's hardening and the edges are crowding in. He continues to be sound and last night and today we hand walked outside. It was even dry enough outside today that I put him in a small paddock with a pile of hay before I left, and the barn staff kept an eye on him for an hour or two of turnout.
Massage on Sunday, 5 week checkup on Monday, and then another few weeks of being careful and maybe I get to start riding!
Here he is as I left him this morning.
