What does “Chronic Renal Failure” mean?
Many people think that “chronic kidney failure” or “chronic renal failure” means that the kidneys have stopped working and are not making urine. Fortunately, this is not the case. By definition, chronic renal failure (CRF) is the inability of the kidneys to efficiently filter the blood of its physiological waste products, not the inability to produce urine. Ironically, most dogs in kidney failure produce large quantities of urine, but the body’s toxic wastes are not being effectively eliminated.
