My pom was diagnosed with renal failure Fri. His BUN is 108, Phos 8.3 and the creatinine level was to high to register. No urinalysis was done. I am wondering from information found online at various resources, could it be possible that he has just a UTI or some other form of Kindey problem? My vet put him on Renavast, 100 ml subQ fluids daily and K/D and has recommended Nutramax fish oil today. He is also now anemic and diabetic (GLU 224, RBC 2.92, HCT19.1, HGB 7.1, AMYL 1762 and LIPA 1045). I have read that without doing an urinalysis, that the complete kidney workup was not done and therefore it could be just an UTI and want to help clear up any misconceptions my husband and I have. Any assistance in this would be greatly appreciated. And can I try an antibiotic?
