Elevated BUN level, but normal Creatinine My sweet Emily, will be 14 this month. She had an elevated BUN level of 46 during the summer, prompting vet to put her on K/D diet. Last week her BUN level is up to 112, but creatinine is normal. All other levels are normal. She tested positive for occult fecal blood, but today's ultrasound shows no abdominal tumors or ulcers which would cause this. Ultrasound does show some nodules on her liver, and one on her spleen (which is totally unrelated to the BUN level, and could be nothing, according to the vet.) She was on Deramax for a few months, but vet says this should not elevate BUN levels. We don't know what to do next. She eats well, and poops healthy daily. Her energy level is crazy strong lately. Aside from some mild demetia (staring at walls and pacing occasionally) she shows no distress. What direction should we go next? Anyone with any experience in this, your help will be greatly appreciated. Thanks! |
Has your vet suggested another plan, perhaps other tests? Perhaps a consult with an internal medicine specialist? I will say that when I have had pups who were on kidney diet, they did not care much for K/D. If she turns her nose up to it, ask your vet about switching to Purina N/F. My kidney diet pups have always preferred that one. |

is your dog drinking enough water? dh brother had a cat with kidney issues and vet told them to have a water bowl in every room to encourage drinking. My maltese had high bun prior to dental but creatinine was normal at .9 and they had me worried about it and i believe it was 39 would have to look up again but she is fine. She is almost 6. I change water 3-4 times a day as she will not drink unless it is fresh and i use spring bottled water. What is urinalysis of your dog as urine also is important in dogs with kidney issues I would join this group as they deal with kidney issues and are very knowledgeable about blood work i am sure K9KIDNEYS : for owners of dogs with Kidney Disease |
If you are concerned and not believing your vet about Deramaxx, here is a link with some information. I believe he knows your pup well enough and has seen her lab results in full and is more than likely correct in saying it was not the medication. If you are not happy with his plan, again I would suggest an internal med. specialist, preferably board certified. Anyway...here is the link: http://www.fda.gov/downloads/AnimalV.../UCM050385.pdf |

here is some information from FDA regarding NSAIDS in vet medicine and how it affects the kidneys Veterinary Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) |
Thanks Wow, thanks everyone for all the advice. Yes, she drinks plenty of water, and her urinalysis came back normal. I have scheduled an appointment with an internal specialist for Monday. Will update as soon as we know anything. This forum is really great- so nice to know there are so many yorkie lovers out there. :-) |

Bag 382, sounds like her liver. Occult (or hidden) blood is higher up in the GI tract. It cannot be seen with naked eye must be tested with culture. Bright red blood in stool is lower GI bleed. Because urea is synthesized (or manufactured) in the liver, liver failure causes a reduction of urea in the blood. I would have the vet run some liver enzyme tests on Emily. I know for people its the ALS and ALT enzyme tests that are the hallmark "markers" of liver inflammation or damage. |
I agree that this sounds more like a liver problem to me - Liver problems can cause an elevated BUN as well. So can dehydration. Where her electrolytes (Sodium (NA), Potassium (K), and Chloride (CL) generally) checked? If so, what where those values? What where her liver values? Personally, I'd try a liver-friendly diet for a short while. I generally use a mixture of white fish (such as pollock) slowly boiled to retain most of the nutrients, rice, and sweet potato for 2-3 weeks and then retest to see if it's made a difference. NSAIDS can affect either liver or kidney health - So the Deramax could also be causing the elevated BUN. I personally try to avoid them - I have better luck with Gabapentin for arthritis pain, combined with Duralactin (works similar to NSAIDS, but all natural and, in my experience, more effective), Adequan, and Dasuquin + MSM or another high quality joint supplement. |
