My dog's abnormal blood test results: High levels & raw diet?

Updated On September 23rd, 2025

Pet's info: Dog | Yorkshire Terrier | Male | unneutered | 9 years and 2 months old | 9 lbs

Just got blood test results for my dog (age 9) Charlie after trying to neuter my dog today. Couldn’t do surgery as abnormal results. Have had to make an appointment to further investigate but this is in a weeks time and I’m getting worried so would like some answers. What do the red results mean exactly? I wasn’t given much information other than to make another appointment to look at it further. Will a raw diet cause any of these levels to increase? Thanks, just want my mind eased a little

I'm sorry to hear that Charlie's surgery was postponed, but looking at these results, I agree that it's best to first investigate further. I see that both Charlie's ALT and GGT are elevated. Both of these enzymes increase with insult to the liver from a variety of different causes, such as chronic hepatitis or hepatitis, among others. When both BUN and creatinine increase, kidney disease is the cause. In Charlie's case, his creatinine is normal, so kidney disease is less likely the cause of the BUN increase, but it could indicate very early kidney disease. It is possible that his BUN increase could be associated with his diet, particularly a raw diet, but diet won't impact liver enzymes to that degree. Additional testing is certainly needed. At this point, I assume that your vet has likely recommended rechecking these values in a week or so, and may have also recommended a urinalysis and abdominal ultrasound to try to get to the bottom of this issue. There's no need to panic - additional information is just needed. I've attached links to a few articles about interpreting blood test results that may be helpful to you. I hope that everything goes well for Charlie! https://www.petcoach.co/article/chemistry-panels-tests-for-pets/ https://www.petcoach.co/article/blood-cells-complete-blood-counts-cbc-in-animals/
