Trying to address all the questions/advice at once:
Tanza, I didn't think to ask about the blood values. I will get a copy though. The doctor just let me know that his white blood cell count was elevated and all other values were fine.
As far as the scope goes… when he was just sneezing, the doctor flushed his nasal passages with saline, did x-rays, drew samples from his lymph nodes, etc. At that point, he wasn't very sick so there wasn't a huge sense of urgency. We were trying to knock out the most obvious causes before moving on to a specialist with a scope. When we finished the first round of antibiotics, he perked up for a few days so we thought for a couple of days he was improving. Then he took a sharp turn for the worse. At this point, the poor guy's nose is swollen & sore from licking, and we want to get the infection knocked out before we subject him to any prodding around in his nose.
As far as his name, we came up with that before we got him. We were looking for a puppy, tossing names around, searching the internet for a few weeks. One evening it just popped into Andrew's head, and I thought it was a great, cute name. It suits him well. I can't imagine him with a more dignified name. He has never had nose issues until now, and the irony of his name/condition has not escaped us.
Right now, he has improved a good bit since mid-week. He's still spending the majority of his day and night sleeping, but he's getting up to eat, to go out & to greet us when we come home! Yay!
