Canine otitis externa is inflammation of external ear canal, causing discomfort to the patients. In the present study, dogs displaying symptoms of otitis externa associated with Malassezia spp. were studied. Twenty-eight dogs were included based on the cytological investigations, out of which 13 being mono-infections of Malassezia spp. and 15 being mixed infections involving both Malassezia spp. and bacteria. Cytological grading was conducted in all the cases. Animals were categorized into two groups for treatment. Group I (n=15) was given oral Ketoconazole, while Group II (n=13) received Itraconazole. The therapeutic efficacy was assessed on days 7th and 14thpost-treatment.
