The objective of this research work was to identify Malassezia pachydermatis in Canis familiaris with otitis externa, through exfoliative cytology and culture. Considering an acceptance percentage of 90% and an estimated error of 10%, 90 dogs with acute and chronic otitis externa were selected, and with the authorization of their guardians as inclusion criteria. A data collection form was used for Canis familiaris with otitis externa. In microscopic identification using Gram staining, 83.3% positive cases were determined for structures suggestive of Malassezia. which occurred more frequently, more than 10 yeasts per field. Isolation on Sabouraud Agar with chloramphenicol was 88.9% positive for colonies of Malassezia pachydermatis, highlighting its use in diagnosis. Likewise, it is reported that the majority of canines that suffer from external otitis are females, adults and breed, the majority of participants are bilateral, with abundant, brown and bad-smelling earwax, and with clinical signs in order of frequency: Erythema, scaling, stenosis, hyperplasia and hyperkeratosis. Statistical analysis was performed using the Chi square test, revealing an association between race and the presentation of otitis externa due to Malassezia pachydermatis
