Abstract
A 4-year-old, intact female Border Collie was presented for evaluation of hearing impairment. Clinical,neurological, otoscopic and magnetic resonance imaging examinations were carried out to determine the cause of hearingloss, but no remarkable change was found. Then, brainstem auditory-evoked response test was performed to assesshearing loss, and the dog had a bilateral sensorineural deafness was revealed. Since possible causes of acquired hearingloss were ruled out by several examinations and history taking, bilateral later-onset deafness was suspected to be geneticand not congenital. This report suggested the possibility that dogs had inherited later-onset sensorineural deafness.
