My dog has a UTI and high kidney levels. Is E. Coli possible?

Updated On September 23rd, 2025

Pet's info: Dog | Boxer | Female | spayed | 2 years and 4 months old | 65 lbs

My 2.5 yr. old boxer had a seizure a month ago. Took her to the vet did blood work & urine sample. Liver, Kidney, & pancreas levels came back high & she had a severe UTI. She was acting normal before & after. They put her on an antibiotic for the UTI & said come back in a month. Which we did. They retested. UTI was back & kidney & pancreas levels were still high. They tested for leptospirosis & put her on Doxycycline. Test was negative. Now they say she has E. Coli. Is this possible?

Yes, as strange as it may sound, it is fairly common for dogs to have a urinary tract (and sometimes kidney) infection where the primary pathogen is E. coli. In humans E. coli usually causing GI disturbances but in animals we see it cause infections in the urinary tract. I would recommend that your vet performs a sensitivity on the E. coli so you can be sure the antibiotics she is on will kill the bacteria. These can be fairly nasty infections and can take several weeks (4-6) on antibiotics to clear. I would also recommend having an X-ray performed to make sure Delilah does not have any bladder stones as this can cause infections to linger as well. Best of luck with Delilah.
