Brainstem auditory evoked response testing in normal hearing cavalier king charles spaniel dogs

Purpose of Study

The purpose of this study is to obtain BAER data from normal hearing CKCS dogs between the ages of 1 to 2 years old with no history of hearing loss.  This is a 2-day study.  Procedures performed include hearing testing (BAER test), a Computed Tomography (CT) scan and Magnetic Resonance Imaging (MRI); study pays for all testing.

 Background

Hearing disorders are a common condition recognized in many breeds of dogs.  In the dog breed Cavalier King Charles Spaniel (CKCS), hearing disorders may be due to conductive hearing loss, which may occur with primary secretory otitis media (PSOM), or do to sensorineural hearing loss, which may occur when there is damage or an abnormality of the sensory cells in the cochlea or the auditory nerve.  Evaluation of a dog’s hearing ability is done using the brain-stem auditory evoked response (BAER) test. However, in order to identify an abnormality on the BAER test, the results from an individual dog must be compared to normal BAER values.
