UPDATE!!!
Talked to our vet. Rocky's blood work came back absolutely normal! yippee! happy dance ensues! However, this fantastic news is tempered with the news that his kidneys are no longer responding to ADH (anti-diuretic hormone). Therefore, we will continue to see a ten-fold increase in his urine output. This also accounts for why he pees in his sleep without realizing it. This portion of the syndrome will steadily get worse as it progresses. unfortunately.
But the great news is that he isn't in Kidney/Renal failure yet! Yippee!! Yes, he has a chronic UTI & bladder infection (no, he does not respond to antibiotics anymore) but we're able to physically manage the urine while I'm away from the house and at night with "belly bands" and Depends pads. So life is back to "normal" for now. Rocky still wakes up happy with a smile and yodel. We have a follow-up in 30 days again to see where he stands.
It still amazes me that a dog so sick can have "normal" bloodwork. It just re-affirms for me that lab results don't always provide the answers they are perported to.
I'll keep you guys posted as this progresses.
