ABSTRACT
Central deafness can theoretically result from a variety of retrocochlear lesions but is very rare in veterinary practice2,13. Bilateral central deafness requires bilateral lesions of the auditory cortex or lesions of such a significant portion of the brainstem or midbrain, that significant clinical signs beyond deafness are to be expected2,13. Peripheral hearing loss in dogs is much more common and has been classified as: • Inherited or acquired. • Conductive or sensorineural. • Congenital or late-onset2,4,13.
