As with people, many dogs suffer some degree of hearing loss. It is important for the guardians of canines to be able to detect signs which may indicate a hearing loss problem. When such a situation has been identified, it is important for the animal’s guardians to ensure that their four-legged family member receives veterinary care. It is also important for people who live with deaf or hearing impaired dogs to learn how to communicate with, and care for, their companions so that they can continue leading normal and comfortable lives.
Types of Deafness
There are two types of deafness
- acquired and congenital. Congenital deafness occurs due to a defective
gene which results in a malformation or nonfunctional ear. In Susan Cope
Becker’s book, Living With A Deaf Dog, 64 dog breeds with reported
congenital deafness are listed. Some of these breeds are more susceptible
to deafness than others. Congenital deafness in dogs is permanent.
Acquired deafness occurs for any number of reasons. Some of the causes of hearing loss include: excessive amounts of wax, dirt, hair or other material plugging the ear canal; inflammation or swelling of the ear canal; infections of the middle or internal ear; a torn or ruptured ear drum; loud noise; head trauma; ear mites; certain drugs; old age.
Signs To Look For
Some of the signs to look
for which may indicate that your dog is deaf, suffering some hearing loss
or is experiencing some ear problems which may lead to hearing loss include:
inattentiveness or a change in obedience; confusion when given familiar
vocal sounds; excessive barking; unresponsiveness to sounds; being difficult
to wake up; head shaking; head tilts toward the side of the affected ear;
itchy and/or painful ears; change in personality; a smelly discharge from
the ear.
Testing For Deafness
If you suspect that your
dog may be deaf or suffering some degree of hearing loss there are some
simple tests that you can do. One test involves sneaking up behind your
dog and clapping your hands or snapping your fingers and observing any
reactions. Do this from a distance so your dog doesn’t detect your actions
or scent or feel any vibrations. If you suspect that your dog is suffering
some degree of hearing loss, have this confirmed by your veterinarian.
Some causes of hearing loss are treatable. As well, there are other veterinary
specialists (i.e. neurologists) who are able to confirm deafness.
One test that evaluates deafness through the use of computers is the BAER (brainstem auditory evoked response) procedure. By using electrodes placed under the skin of a dog’s scalp and which are connected to a computer the brainstem auditory response can be measured. There are five BAER testing sites in Canada listed in Susan Cope Becker’s book, Living With A Deaf Dog.
Keeping Your Deaf Dog
Safe
There are many things that
you can do to keep your deaf or hearing impaired dog safe. Deaf dogs should
be kept on a leash or in a fenced-in yard while outdoors. Children should
also be taught how to interact with, and behave around, deaf dogs.
Learning how to communicate with, and train, your dog using hand signals is important. Whether you use your own signals, standard obedience signs, American Sign Language or a combination of these, it is important that you, and others who communicate with your dog, are consistent with the signs you use. As well, it is a good idea to use signs which only use one hand and which are easily detected by your dog from a distance.
In her book, Living With A Deaf Dog, Susan Cope Becker has included two informative chapters (“How To Communicate With Your Deaf Dog” and “Deaf Dog Traits, Training and Safety Tips”) which will help guardians of deaf dogs train, communicate with, and help keep their hearing impaired canines safe. There is also considerable information available on the Internet.
Dogs commonly experience a gradual hearing loss as they age. During the last couple of years Winston, our old Terrier cross, has lost most of his hearing. He occasionally hears very loud, and sometimes high-pitched, noises. A couple of years before he lost his hearing Winston lost his eye sight. Dogs who lose one of their senses rely more heavily on their other senses which become more acute. Winston’s sense of smell these days is very good! He sniffs out any food carelessly left on the kitchen counter and, standing on his hind legs, reaches up and snatches it!
Whenever we enter the room where Winston is we let him know of our presence by gently touching him on the back or shoulder. Even though he is blind and deaf Winston leads a normal, productive and happy life. He finds his way by knowing where all the furniture and appliances are in the house and all the trees, bushes, holes and other “landmarks” in the fenced-in yard. Winston also moves about efficiently by being near his canine siblings and using them for guidance and, when necessary, relying on his human family members to show him the way. When Winston is being walked outside the fenced-in yard he is always on a leash.

be rewarded with a wonderful and loving companion.
