My dog has kidney disease. What do her blood test results mean?

Updated on September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Female | spayed | 13 years and 3 months old | 90 lbs

Please tell me what these test results says regarding Summer... my vet just said that her kidney is bad. That’s all. I’d want to know everything to know off the test results please. Thank you for all the help. Also I noticed yesterday when summer peeed, what got my attention is that the amount of pee was much much more than her usual also today .. considering I had lowered dosage of lasix already... should this be alarming? Many thanks

This is best to discuss during a one-on-one consultation; however, the blood work results reveal that your pet has a high white blood cell count (indicates infection or inflammation), mild anemia (low red blood cells), a UTI with a low specific gravity (concentrating ability of the kidneys which should be rechecked once UTI resolved, as well as protein in the urine which should be rechecked after resolution of UTI. as well as high BUN, CREA, which suggests kidney damage or kidney failure.

Because of the concurrent UTI, it is best to resolve the UTI with anti-biotics, perhaps consider a SDMA test (specific kidney disease test) to confirm suspected kidney disease/insufficiency, and then rechk Urinalysis in 2 weeks.
I am not sure why your pet is on Lasix, unless there is also underlying heart diseasee, which could have caused the erroneous reading of low specific gravity on the test.
If there is more to discuss, then pleasea don't hesitate to request a private consultation for this, because this is a complicated case that needs to be on a more personal level in order to get full clarity on the recommendations above.
Best wishes and take care.

My dog's kidney tests show different stages. What do the results mean?

Hello. I am sorry about the diagnosis of kidney disease in Layla. We do generally stage kidney failure based on certain markers in the blood. This includes blood urea nitrogen ( BUN ) & creatinine. Another test, called SDMA is a very sensitive marker for very early kidney disease. Specific gravity refers to the amount of solids found in urine. If urine is very dilute ( has a low specific gravity ), this is a poorer sign, especially if there is also protein in the urine. We really need to look at everything, blood & urine, to determine how serious or dangerous the kidney disease might be, but that is why we sometimes need to look a little further to understand exactly what might be going on. I hope you can work with your veterinarian to manage Layla's kidney problems. Good luck & thanks for using Petco Pet Education Center, formerly Petcoach.

What do my dog's blood and urine test results say about his health?

The blood test is just fine. I do not see any abnormalities. The urine tests are pretty normal as well. No bacteria or crystals. Some white and red cells present can be normal. There may be some early kidney disease with the presence of microalbuminuria but more testing would need to be done. These test results need to put together with the dogs clinical signs. I'm not sure what you are trying to decipher. What are the dog's clinical signs? There is not enough information here for us to be helpful. You may want to opt for a private consult with me or one of our other experts so we can chat back and forth. That way we may be able to help you better.

Can I get a second opinion on my 7-year-old Lhasa Apso's blood test?

Thank you for submitting your question regarding Sundari. Her BUN and Cr are mildly elevated. This can indicate early kidney disease, but there are other causes as well. Simple dehydration will make these values increase. I would recommend that she has a urinalysis performed on a first morning urine sample. This sample will be the most concentrated and give you more information regarding how the kidneys are functioning. There is also a new blood parameter known as SDMA. This is much more sensitive indicator of kidney function than BUN/Cr. I would recheck her blood work in 1-3 months to monitor the liver value (ALT) that is slightly elevated to see if this is a consistent finding. Liver enzymes can fluctuate in the blood stream so this may not be significant. I hope this information helps!

My dog has renal failure, but no urinalysis. Could it be a UTI?

Without seeing the blood work, I wouldn't be able to say if it is renal failure or not. If the BUN and Creatinine are elevated extensively and especially if the phosphorus is elevated then unfortunately Angel is most likely in renal failure. A urinary tract infection should not cause elevations in those values unless there is also a secondary kidney infection going on and she is in kidney failure due to that. I would recommend either requesting a consultation or resubmitting a question with the blood work attached. I am so sorry Angel isn't feeling well.

My cat's blood tests show anemia and possible kidney disease. Help!

Hi, I don’t think it is possible to diagnose a disease from these blood tests and without any clinical history or symptoms and a physical examination. It does seem like Russia has anaemia and increased white blood cells on her haematology blood tests, her biochemistry shows mild azotaemia with an increase in both urea and creatinine. This could indicate kidney disease. Has Russia had any urine test ? I would run a urine test,sg dipstick, protein creatinine ratio and start intravenous fluids. More tests are available to evaluate renal functions but I am not sure if these can be done in Egypt. Hope this helps.

My dog's blood test shows high urea & creatinine. What's wrong?

This could indicate renal issues/kidney disease. Leo needs to have an analysis done of his urine to check further for any signs of infection as well as to make sure he's not dehydrated and causing the signs. If it is early renal disease there are certain steps we can take to manage it. This could include medication to control blood pressure, a diet change, or even giving him fluids therapy. He may need medications to protect his stomach from ulcers. I recommend discussing these options with your veterinarian as well as any additional testing such as an ultrasound of his kidneys and liver.

My dog has low WBC count and kidney issues. Should I be worried?

In looking at the bloodwork you attached, I would not be concerned about the total White Blood Cell value being slightly lower than normal. After the total WBC value, the bloodwork breaks it down into individual white blood cells, like neutrophils and lymphocytes, none of which are too low. In fact, neutrophils, the body's first responders to infection or inflammation, are a little higher than the normal range. White blood cells are the fighters of the immune system, and it appears that Mary still has plenty in case she needs them. There is nothing you can do raise them other than keep her in good health. However, I do see that both BUN and Creatinine are also elevated. This can happen for many reasons, including severe dehydration, kidney insufficiency or failure, kidney infection, among others. These are the more concerning numbers that I see, and I am sure your vet has discussed a plan of action for these values.
