Hi Armadilo,
I am sorry to hear your about your little guy.

I agree with Deja and Becki, I think maybe a vet trip would be the only sure way to know anything. I had a situation with my papillon Jasmine, where at a time they thought she had a kidney issue. Thankfully, after a battery of tests, all turned out normal, her BUN levels were normal and after a trip to the specialist, her actual diagnosis was a food allergy. After reading your story, it sounds like it is possible something kidney related could be going on. Has there been any blood in his urine? Any other signs? There is another disease someone here on PT told me about awhile back, when I was asking for advice about Jazzy, and I asked my vet about it, (and it wasn't something she has) but some of the main symptoms are excessive drinking and urination. It is called Cushing's disease. I don't know if this could be something to check with your vet about. I would definately make an appt. as soon as possible. It definately sounds like something serious going on.

Please keep us updated and I hope your little guy feels better. My thoughts are with you.
