There is no way to be able to tell how long she will live however you can significantly prolong Linda's life with feeding her a kidney diet, such as from Hill's Science Diets or Royal Canine kidney diet. A Creatinine level of 2.0 is not yet alarming, just slightly high.There are other kidney parameters to check such as Blood urea nitrogen and Phosphates, and if they are within the normal values, I would not worry too much about CREA 2.0. Feed a kidney diet and that should be beneficial.

    This is a condition known as renal dysplasia, and Linda has a better prognosis if she has one normal size kidney. The onset and clinical disease symptoms are highly variable, and kidney failure from this birth defect can occur at any age, including dogs that are older than 10 years. It's hard to say how long she will live with this condition, but it's good that she has shown no sign of illness to date. Blood chemistry and urine content should be monitored regularly to check for signs of kidney failure, and your vet may want to do it as often as every three to six months. Linda may be one of the lucky dogs that don't develop signs until later in life, so fingers crossed that happens. I'm sorry I can't give you an exact answer to your question, but I hope this helps somewhat!

    Hello. With both the BUN & creatinine elevated, kidney insufficiency is definitely present. Creatinine is the more definitive measurement so with a value of 2.33, according to the International Renal Interest Society ( IRIS ) Naughty is in stage 3 renal failure. However, we do need additional information to see what & if anything can be done to extend his life. Your veterinarian should run an SDMA ( if available in your country ), we need to see a urinalysis, including a urine protein/urine creatinine ratio & we need to know what Naughty's blood pressure is. If he is truly in Stage 3 renal insufficiency/failure, we will not be able to reverse or cure his kidneys, but there are things that can be done to minimize further damage. This can extend his life for quite a long time depending on what is found & the underlying cause of his condition. I hope Naughty is doing well soon & thanks for using Petco Pet Education Center, formerly Petcoach.
