Dog hearing tests are a valuable tool for figuring out if our dog has developed hearing issues or was perhaps born deaf. Often, when we think a dog is ignoring us, they may actually be displaying signs of hearing loss. Sometimes dogs lose their hearing with age, sometimes they develop hearing problems for medical reasons, and sometimes they are born deaf.
If you suspect your dog has trouble hearing, it’s vital to find out if they can hear at all, and how much they can hear. This is so that you quickly work out a strategy to improve how you communicate with your dog and adjust their environment to improve their quality of life. So, how can you test your dog’s hearing?
So, How Can I Test If My Dog Is Deaf?
If you think your dog may be deaf, there are tests you can perform to confirm your suspicions, such as the clap or whistle test. However, a veterinarian can also conduct hearing tests such as the brainstem auditory evoked response (BAER), the otoacoustic emissions (OAE) test, or the. behavioral observation audiometry (BOA) test.
Some of these tests can be done at home, while others require a visit to the vet. Here are some of the most common tests used to determine if a dog is deaf:
The Clap Test
The clap test is a simple test that can be done at home to determine if your dog is deaf. To perform the test, stand behind your dog and clap your hands loudly. If your dog does not respond to the sound, he may be deaf. However, it’s important to note that some dogs may not respond to the clap test even if they can hear, so this test should be used in conjunction with other tests to confirm deafness.
The Whistle Test
The whistle test is another simple test that can be done at home. To perform the test, stand behind your dog and blow a whistle. If your dog does not respond to the sound, he may be deaf. Again, it’s important to note that some dogs may not respond to the whistle test even if they can hear, so this test should be used in conjunction with other tests to confirm deafness.
BAER Test
The BAER (Brainstem Auditory Evoked Response) test is a more accurate test for determining if a dog is deaf. This test is performed by a veterinarian and measures the electrical activity in the brain in response to sound. The test is non-invasive and does not require anesthesia. The BAER test is considered the gold standard for diagnosing deafness in dogs.
Other types of hearing tests for dogs include the otoacoustic emissions (OAE) test, which measures the sounds produced by the inner ear in response to sound, and the behavioral observation audiometry (BOA) test, which involves observing a dog’s response to different sounds and frequencies. However, this test is usually performed on human infants.
These tests can be useful for assessing a dog’s hearing abilities in different contexts and can provide valuable information for owners and veterinarians alike.
It’s important to note that deafness in dogs can be caused by a variety of factors, including genetics, age, and injury. If you suspect that your dog may be deaf, it’s important to have him evaluated by a veterinarian to determine the cause of his deafness.
Understanding Dog Hearing
To understand dog hearing, it is important to know the anatomy of their ears. Dogs have two ears located on the sides of their head, which are made up of three parts: the outer ear, middle ear, and inner ear.
The outer ear is the visible part of the ear that is covered in fur and shaped like a funnel. It collects sound waves and directs them towards the middle ear, which is located inside the skull. The middle ear contains three small bones called ossicles that amplify the sound waves and transmit them to the inner ear.
The inner ear is responsible for converting the sound waves into electrical signals that the brain can interpret. It contains the cochlea, which is filled with fluid and tiny hair cells that vibrate in response to sound waves. These vibrations are then converted into electrical signals that are sent to the brain via the auditory nerve.
Frequency Range
Dogs have a much wider range of hearing than humans. While humans can hear sounds between 20Hz and 20,000Hz, dogs can hear sounds between 67Hz and 45,000Hz. This means that dogs can hear sounds that are too high-pitched for humans to hear, such as the sound of a dog whistle.
Dogs also have a much better ability to locate the source of a sound than humans. This is because their ears are designed to pick up sound waves from different directions and at different frequencies. They can also move their ears independently of each other, which allows them to pinpoint the exact location of a sound.
In conclusion, understanding the anatomy of dog ears and their frequency range is important when testing a dog’s hearing. By knowing how dogs hear and what sounds they can detect, veterinarians and dog owners can better diagnose and treat hearing problems in dogs.
Importance of Hearing in Dogs
Hearing is one of the most important senses for dogs. It allows them to communicate with their owners and other dogs, detect potential danger, and navigate their environment. A dog’s hearing is much more sensitive than a human’s, and they are capable of detecting sounds that are too high or too low for us to hear.
One of the most important reasons to test a dog’s hearing is to identify any hearing loss or impairment. This can be caused by a variety of factors, including genetics, age, and exposure to loud noises. If left untreated, hearing loss can lead to a decrease in quality of life for the dog, as well as potential safety issues.
Additionally, hearing tests can help identify any underlying medical conditions that may be affecting a dog’s hearing. For example, ear infections or blockages can lead to temporary or permanent hearing loss. By identifying these issues early on, they can be treated before they cause permanent damage.
Overall, regular hearing tests are an important part of a dog’s healthcare routine. They can help identify any issues early on, allowing for prompt treatment and a better quality of life for the dog.
Signs of Hearing Issues in Dogs
Just like humans, dogs can also suffer from hearing issues. Research shows it is important for dog owners to be aware of the signs of hearing loss or deafness in their pets. Here are some common signs that may indicate hearing issues in dogs:
- Ignoring sounds: If your dog doesn’t respond to sounds that used to get their attention, it may be a sign of hearing loss. For example, if your dog doesn’t react to the sound of the doorbell or their name being called, it may be an indication of hearing problems.
- Excessive or no barking: Dogs with hearing issues may bark more than usual. This is because they are unable to hear themselves barking and may not realize how loud they are. Dogs born deaf often may not know how to bark at all.
- Startling easily: Dogs with hearing loss may startle easily when touched or approached from behind. This is because they are unable to hear someone approaching.
- Disorientation: Dogs with hearing loss may become disoriented and confused in familiar surroundings. They may also have difficulty locating the source of a sound.
If you notice any of these signs in your dog, it is important to take them to the vet for a hearing test. Early detection and treatment can help prevent further hearing loss.
Causes of Deafness In Dogs
Studies show that deafness in dogs can be caused by several factors, including congenital sensorineural hereditary, conductive deafness, and a link between deafness with piebald and merle genes. Certain breeds are also more prone to deafness than others, such as Dalmatians, Boxers, and Australian Cattle Dogs.
Conductive deafness is caused by obstructions in the outer or middle ear, which can often be corrected. On the other hand, sensorineural deafness cannot be corrected and is caused by damage to the inner ear or auditory nerve.
In addition, white dogs that are double merles are more prone to being deaf, such as White Great Danes. This is because the merle gene can cause irregularities in the development of the ear and can result in deafness.
It’s important for dog owners to be aware of the potential for deafness in their pets, especially if they have a breed that is more prone to it. Regular hearing tests can help detect any issues early on and allow for proper treatment.
What Dogs Need BAER Hearing Testing?
Some dog breeds are genetically predisposed to hearing issues or deafness, making them prime candidates for regular hearing tests. The deafness statistics for some dog breeds are alarming. According to the University of Louisiana, about 28% of Dalmatians, 20% of white Bull Terriers, 9% of Boston Terriers, and 26.5% of Dogo Argentinos are deaf. In total, about 80 breeds carry the genes to be born deaf.
While any dog can experience hearing loss, especially as they age, here’s a list of some breeds that may be especially prone to these issues due to their genetic makeup:
- Dalmatian;
- White Boxer;
- English Setter;
- English Cocker Spaniel;
- Bull Terrier;
- Whippet;
- Australian Cattle Dog;
- Boston Terrier;
- Maltese;
- West Highland White Terrier;
- Shih Tzu;
- Poodle;
- Rhodesian Ridgeback;
- Dogo Argentino;
- Italian Greyhound; and
- Miniature Pinscher.
It’s worth noting that hearing loss can also be related to a number of factors beyond breed, including age, exposure to loud noises, and overall health. Particularly for breeds that are predisposed to deafness, early hearing tests and regular check-ups are vital to identify any issues as early as possible and ensure our furry pals get the right support they need. Always consult with a veterinarian or a canine audiologist for accurate and personalized advice regarding your pup’s hearing health
Types of Dog Hearing Tests: How Vets Check Hearing Loss
There are several types of hearing tests you should do on dogs that may be vulnerable to hearing loss:
Brainstem Auditory Evoked Response
Brainstem Auditory Evoked Response (BAER) is a test that measures the electrical activity of the brain in response to sound. This test is performed by placing electrodes on the dog’s scalp and recording the brain’s response to sounds of varying frequencies and intensities. BAER testing is commonly used to diagnose hearing loss in puppies and adult dogs.
The BAER test is a non-invasive procedure that is safe for dogs. The test is usually performed under sedation, and it takes about 30 minutes to complete. The results of the BAER test can help veterinarians determine the severity and type of hearing loss in dogs.
Otoacoustic Emissions Testing
Otoacoustic Emissions (OAE) testing is a non-invasive test that measures the sounds that are produced by the inner ear in response to sound. This test is performed by placing a small probe in the dog’s ear canal and measuring the sounds that are produced by the inner ear. However, it’s a bit trickier to do on dogs than on human babies.
OAE testing is commonly used to diagnose hearing loss in puppies and adult dogs. The test is safe and painless and can be performed without sedation. The results of the OAE test can help veterinarians determine the presence and degree of hearing loss in dogs.
In summary, there are two primary types of hearing tests for dogs: Brainstem Auditory Evoked Response (BAER) and Otoacoustic Emissions (OAE) testing. Both tests are non-invasive, safe, and effective in diagnosing hearing loss in dogs. Veterinarians may use one or both of these tests to determine the type and severity of hearing loss in dogs.
Procedure of Dog Hearing Tests
Dog hearing tests are conducted to determine the extent of a dog’s hearing ability. There are a few different methods that can be used to test a dog’s hearing, including the Brainstem Auditory Evoked Response (BAER) test, the Electroretinogram (ERG) test, and the Otoacoustic Emissions (OAE) test.
The BAER test is the most common hearing test used for dogs. During this test, electrodes are placed on the dog’s head and the dog is exposed to a series of clicks or tones. The electrodes pick up the electrical activity in the dog’s brain in response to the sounds. This activity is then recorded and analyzed to determine the dog’s hearing ability.
The ERG test is used to evaluate the function of the retina in the dog’s eye. During the test, a small electrode is placed on the dog’s cornea and a light is flashed in front of the dog’s eye. The electrode measures the electrical activity of the retina in response to the light. This activity is then recorded and analyzed to determine the dog’s retinal function.
The OAE test is used to evaluate the function of the inner ear in the dog. During the test, a small microphone is placed in the dog’s ear and a series of clicks or tones are played. The microphone picks up the sounds that are produced by the inner ear in response to the sounds. These sounds are then recorded and analyzed to determine the dog’s inner ear function.
Overall, dog hearing tests are an important tool for evaluating a dog’s hearing ability. By using these tests, veterinarians can diagnose hearing problems early and develop treatment plans to help improve a dog’s quality of life.
How Can I tell if My Dog is Deaf at Home?
It is important to check if your dog can hear you properly as hearing loss can affect their quality of life. Here are some ways to check if your dog can hear you at home:
Clap Test
One of the easiest ways to check if your dog can hear you is to perform a clap test. Clap your hands behind your dog’s head or in another room. If your dog turns around or reacts to the sound, it is a good indication that they can hear you.
Whistle Test
Another test you can try is the whistle test. Use a dog whistle or a high-pitched whistle and blow it near your dog’s ear. If your dog reacts to the sound, it is a good indication that they can hear high-pitched sounds.
Call Test
You can also try calling your dog’s name from another room or from behind them. If your dog turns around or comes to you, it is a good indication that they can hear you.
Other Signs of Hearing Loss
If your dog does not react to any of the above tests, it may be an indication that they have hearing loss. Other signs of hearing loss in dogs include:
- Not responding to commands or their name;
- Sleeping more than usual;
- Barking excessively; and
- Not reacting to loud noises.
If you suspect that your dog has hearing loss, it is important to take them to a veterinarian for a proper diagnosis and treatment.
Interpreting Hearing Test Results
After conducting a hearing test on a dog, it is important to interpret the results accurately. The following are some guidelines to help interpret the hearing test results.

- If the dog has normal hearing, the chart will show a clear response to each frequency.
- If the dog has unilateral hearing loss, the chart will show a clear response in one ear and no response in the other ear.
- If the dog has bilateral hearing loss, the chart will show no response in both ears.
OAE Test Results
The results of the OAE test are presented in a chart that shows the responses of each ear to different frequencies. The chart will show whether the dog can hear each frequency and whether there is any hearing loss. The following are some guidelines to help interpret the results:
- If the dog has normal hearing, the chart will show a clear response to each frequency.
- If the dog has mild hearing loss, the chart will show a reduced response to some frequencies.
- If the dog has moderate hearing loss, the chart will show a reduced response to most frequencies.
- If the dog has severe hearing loss, the chart will show no response to most or all frequencies.
Behavioral Test Results
Behavioral hearing tests involve observing the dog’s response to different sounds. The following are some guidelines to help interpret the results:
- If the dog responds consistently to all sounds, the dog likely has normal hearing.
- If the dog does not respond to some sounds, the dog may have hearing loss.
- If the dog does not respond to any sounds, the dog may be deaf.
It is important to note that hearing test results should always be interpreted by a qualified veterinarian or specialist.
Treatment and Management of Hearing Loss in Dogs
Hearing loss in dogs can be a challenging condition to manage, but there are several treatment options available. The treatment plan will depend on the underlying cause of the hearing loss and the severity of the condition.
Medical Treatment
If the hearing loss is caused by an infection or inflammation in the ear, antibiotics or anti-inflammatory medications may be prescribed to treat the underlying condition. In some cases, surgery may be necessary to remove tumors or other growths that are causing the hearing loss.
Hearing Aids
Hearing aids can be a useful tool for dogs with hearing loss. These devices amplify sound and can help dogs hear better in certain situations. However, not all dogs are good candidates for hearing aids, and they can be expensive.
Training and Communication
Dogs with hearing loss can still lead happy and fulfilling lives with proper training and communication. Owners can use hand signals or visual cues to communicate with their dogs, and many dogs can be trained to respond to these signals just as well as they would to verbal commands.
Lifestyle Adjustments
Owners of dogs with hearing loss may need to make some adjustments to their dog’s lifestyle. For example, they may need to keep their dog on a leash or in a fenced area to prevent them from wandering off and getting lost. They may also need to be more mindful of their dog’s surroundings and potential hazards.
Overall, the key to managing hearing loss in dogs is to work closely with a veterinarian to develop a treatment plan that is tailored to the individual dog’s needs. With the right care and attention, dogs with hearing loss can still live happy and healthy lives.
