Staphylococcus beta hemolitic (26.27%), Malassezia pachydermatis (12.35%), and Pseudomonas aeruginosa (8.8%) were the most common microorganisms identified. The isolates were susceptible mainly to norfloxacin (89.62%), gentamicin (83.25%), and ofloxacin (80.16%). High occurrence of resistance of isolates was observed to neomicin (30.84%) and cephalexin (27.63%). Multiple drug resistance to three or more and five or more of antimicrobials tested was observed in 34.9% and 15.5% of isolates, respectively. The cases of canine otitis occurred predominantly in first years of age, in mixed breeds animals, at autumn season. The presence of itch, bad smell, and secretion in ear conduct were the major signs observed at clinical examination.
