What is Brainstem Auditory Evoked Response (BAER) Testing?


A BAER test is a non-invasive test that one of our board-certified veterinary neurologists can run to confirm any hearing loss in your pet. At Southeast Veterinary Neurology, we can use this test to check for any type of deafness, which includes inherited, congenital, conductive, or sensorineural deafness. Knowing the type helps us determine specific treatment options for your pet’s situation.

Why Does My Pet Need BAER Testing?

Have you noticed your dog doesn’t come anymore when you call him or that it seems easier for other animals to sneak up on him without him being aware? If you suspect your pet may be fully or partially deaf, you should contact us so that one of our veterinary neurologists can run a BAER test. Your pet may also be more likely to need this testing due to its breed. Certain breeds are prone to congenital deafness (deafness at birth). These breeds include Dalmatians, white Boxers, English Setters, and white English Bull Terriers.


How Is the Testing Done?

With BAER testing, we measure the electrical activity in your pet’s auditory nerve pathway in response to a number of clicks transmitted to their ears through headphones. Our trained veterinary neurologists can diagnose hearing loss and possible brainstem disorders by tracking these electrical signals between the inner ear receptors and the cerebral cortex. Cats and dogs can be awake or asleep through this test, and it takes about 10 to 15 minutes to complete. We test each ear individually to help us localize any abnormalities in your pet’s hearing or brain function. We can only perform this test on puppies that are at least 6 to 8 weeks old, because their ear canals are not fully open before then. It can be done on any adult dogs.
