Electrodiagnostic evaluation of deafness in two English setter littermates.
Two English Setter littermates (male and female) were evaluated for hearing difficulties at 4, 16, and 24 months of age. Auditory function was evaluated by behavioral response to pure-tone sounds, tympanometry, brain stem auditory evoked response, and acoustic reflex testing. Hereditary sensorineural deafness was diagnosed in both dogs. The extent of the hearing deficit, as characterized by these tests, was slightly different between the dogs, as well as between the ears in 1 dog.
