Oh, I'm sorry to hear this I've had experience with UTI in dogs, but no expereince with kidney disease in dogs. Is this the same vet that treated her previous UTI's? Usually a urinalysis can rule out a UTI; did they ask you drop off a sample right away? Hopefully you can get the repeat blood work done asap and get some answers. Are you sure she's not having any trouble urinating/having blood in her urine? You mentioned her being in pain the other day and sometimes UTIs and definitely bladder and kidney stones, can cause much discomfort. I definitely think an ultrasound would give you the most definite answer. I'll be keeping your precious Raustyk in my prayers and keeping my fingers crossed for a quick diagnosis and swift recovery! Please keep us updated. HUGS to you Raustyk! Sandra, Cody and Star
