Tris did GREAT today: walked right on the trailer, hauled easily, and walked right into the clinic and into his stall.
I signed a bunch of paperwork, brought in his grain, and there wasn't much else to do. He started eating his hay immediately and behaved perfectly to have his vitals checked. He'll get a catheter for his IV first thing in the morning, and go in for surgery about 1pm. It will last about an hour. He'll get an EWT booster, since he's due soon, and be on lots of antibiotics and IV bute starting tomorrow.
When I got back to the barn I stripped his stall. Tomorrow night I'll spray it down with a bleach/water mix, then re-bed with fresh shavings, nice and deep. He can't come home fast enough.
