The present study was conducted on apparently healthy (n=15) and clinical cases (n=115) of dogs affected with otitis externa. All the sick animals were subjected to clinical, cytological and otoscopic examination. On the basis of these tests animals were divided into 6 groups viz. Bacteria Otitis Externa (n=70), Malassezia Otitis Externa (n=22), Fungal Otitis Externa (n=8), Fly Myiasis (n=9), Aural Tumors (n=5) and Puppy Strangles (n=1). Otitis externa was the most common affection of ears in dogs in summer and rainy season. Bacterial otitis externa was found more in summer and fungal in rainy season. A cocker spaniel was predisposed to otitis externa as compared to other breeds. Pruritis, malodorous & head shaking with erythema, suppuration and pain was a common finding in all the dogs affected with otitis externa in all the groups but fungal cases were having excessive blackish wax with erythematous ceruminous lesions. Staphylococcus was most common bacteria (60%) isolated in cases of otitis externa followed by Proteus (25%) and E. coli (6%). Ceruminous gland adenocarcinoma, melanoma and squamous cell carcinoma were primary aural tumor in geriatrics dogs. Otoscopy was suitable tool for diagnosis of affections of external ear canal in dogs. Microbiological isolation & cytology were suitable for diagnosis and differentiation of bacterial and fungal otitis externa in dogs. Enrofloxacin was the most sensitive antibiotic in cases of bacterial otitis followed by ciprofloxacin
