The vet has come and gone, leaving behind a dopey goat, a pile of drugs, and some hope.
The vet did quite a comprehensive sonogram of most of Gyre's underparts. Gyre's urethra is blocked (though we couldn't see where), but not totally, and his bladder is not enlarged into a dangerous size yet. Nor is his bladder ruptured. So we are going to put him on antibiotics and antiinflamatories and see if we can get him to pass the stone on his own.
My instructions are to feed Gyre normally, encourage water consumption, and see if I can observe him eliminating any urine. If he cannot eliminate, starts really straining, or starts to cry, I'm to page the on-call vet.
So, once Gyre recovers from his knock-out drugs, my evening is going to be spent in the barn with my knitting...
ETA: Gyre is now eating, and produced another weak stream at 6:40 PM. These are good things, both.
At 9PM we visited him again, and again Gyre produced a weak stream to reward us for our visit. He's still uncomfortable, and still doing his little slow potty wiggle-stance.
