Microtia is hypoplasia of pinna that ranges in severity from partial to complete aplasia. Congenital aural atresia (CAA) is one of the most prevalent anomalies recognized with microtia. A 2-month-old male mix dog was referred to the veterinary animal hospital of Shahid Bahonar University of Kerman for vaccination. Clinical examination revealed hypoplasia of pinna in the right ear, whereas the pinna was normal on the left side. On otoscopic examination and radiology, no abnormality was found in the auditory canal and tympanic membrane of affected ear except narrowing compared with the other side. Unilateral congenital microtia and aural atresia were diagnosed. This report is the first description of microtia in dog.
