Unique strategies have evolved in members of this genus to allow their survival within different niches. Although initially the <i>Escherichia</i> cryptic clades (CCs) I-VIII were identified as environmental bacteria, they have been found as commensals and opportunistic pathogens in animals and humans. Notably, members of the <i>Escherichia</i> CCs are commonly mistaken for <i>E. coli</i> when using standard microbiologic techniques for species identification. We used whole-genome sequencing to correctly identify <i>E. marmotae</i>-a member of the <i>Escherichia</i> CCs-that was initially misidentified as <i>E. coli</i> as the causative agent of a urinary tract infection (UTI) in a female dog. The isolate had phenotypic and genotypic resistance to cefalexin-an antibiotic used commonly for the treatment of uncomplicated UTIs-and carried a set of virulence factors also present in uropathogenic <i>E. coli</i>, which would explain the capacity of the organism to colonize the urinary tract. As a relatively new species that is phenotypically very similar to <i>E. coli</i>, it is quite possible that <i>E. marmotae</i> infections may be underreported or misidentified. We hope that our work alerts veterinarians to consider <i>E. marmotae</i> as a possible cause of UTIs in dogs, especially because this could affect treatment decisions.
