All's well! Tris was stoned out of his mind from the dermosedan gel, and did great for his farrier appointment.
Hole continues to look good, 4 weeks out today, and the bottom holes are allllmost gone. They'll go at the next appointment. Once the foot grows that far, we'll start to worry about the next hole, the big one. It's got a crack leading up from the smaller one and a bit of hoof wall that may well separate and be wide open. We'll address that when we come to it. The mushy bit was just dead sole, not an abscess. His sole is in tough shape with the constant moisture of the boot.
In the meantime, keep on keeping on. Up to 15 minutes handwalking each day now, and incorporating poles to work his back a bit.
