    This study aimed to characterize the dermatophyte fungi responsible for infections in dogs treated at the Municipal Pet Hospital and the ARCA Foundation. A total of 104 dogs were included in the study, 52 from each institution. Samples were obtained by skin scrapings from dogs with lesions suggestive of fungal dermatopathies and were processed in the Microbiology Laboratory of the University of Cuenca for culture, incubation, and colony identification. A total of 198 fungal isolates were identified, considering the presence of multiple isolates per sample. Of these, 51% corresponded to the ARCA Foundation and 49% to the Municipal Pet Hospital. Thirteen colony types were identified, of which 31.8% were dermatophytes. The dermatophyte Trichophyton mentagrophytes was the most frequent in both institutions, with a frequency of 29%, followed by yeasts (26%) and Penicillium spp. (15.5%). The difference in the number of isolated colonies between institutions was minimal, indicating that the presence of the various fungal colonies does not depend on the type of institution, but rather on other patient exposure factors. Furthermore, the statistical association between the different etiological agents, the type of lesion, and its anatomical distribution was evaluated using contingency tables. The Chi-square test did not show a statistically significant association (p>0.05), and the low or negative Kappa index indicated poor agreement between the variables, highlighting the importance of mycological culture for accurate etiological identification.
