Can a vet check a dog’s hearing?
Your vet may also test your dog’s hearing by stepping quietly behind your dog and clapping loudly to see if there is any response. Certain veterinary specialists can perform the Brainstem Auditory Evoked Response (BAER) Test. This is the most reliable method for determining deafness in dogs.
What percentage of white dogs are deaf?
