Good. Very good. Really truly very good indeed.
Over the last three days the swelling in the fetlock has gone down to minimal; the heat has reduced to mildly elevated; and Ben's weight-bearing comfort on that leg has been solid. He was turning up his nose at his bute-laced beet pulp and sweet feed mash, so we switched him to one Previcox tablet per day on the 19th. He eats it in a bit of sweet feed from my hand and is doing just fine on it.
I've been able to extend Commander's turnout to a full eight hours, from midday to around 8:00 p.m., without either of them having a meltdown over the separation. I was even able to take Commander out for a short ride along the edge of the hayfields today, yay!
Roxanne and the girls have come over on Wednesday and Friday to groom the boys, fuss over them, and stuff them with carrots, which I'm sure they both enjoyed greatly.
I expect this is still the end of Ben's career as a riding horse, but as long as he's paddock sound and happy, I'm fine with that.
