Deafness is the permanent or temporary loss of hearing.
Deafness can be present at birth or developed after an infection or degeneration of the cochlea, the organ responsible for hearing.
A veterinarian will perform a physical examination of your dog including the ear. Further testing may be needed in the form of x-rays, CT scans, MRIs, or neurological exams to reveal any underlying conditions affecting your dog’s hearing. The best method for testing is the Brainstem Auditory Evoked Response (BAER) test.
This test measures the electrical activity in the cochlea and the brain’s auditory pathways. Access to this technology is not widespread, so while the best method, you may not find it available.
Bacterial infections can be treated with an antibiotic. Infections that cause blockages can be handled surgically. All other forms of deafness will be permanent.
You will still be able to communicate with your dog, you will just have to modify your lifestyle.
