Nobody wants their dog to lose their hearing, but it is a possibility that is important to be aware of, especially if you have certain dog breeds. This is because there are some breeds of dog that are more likely to become deaf.
Thankfully, there are some signs of deafness that you can look out for, so you can be aware of when this happens. There are also some general things to consider when you are looking for the right dog breed for you.
In this article, we are going to take a look at the dog breeds that are prone to deafness, meaning those that are more likely than other breeds to become deaf. We are also going to tell you what signs to look out for, as well as how to get an accurate diagnosis.
Deafness In Dogs
Deafness refers to temporary, partial, or total loss of hearing in either one or both ears. Deafness in dogs is something that can be hereditary, or as a result of a birth defect, trauma, blocked ear canal, or simply old age. There are certain breeds of dogs that are predisposed to deafness, and white or merle-coated dogs are also more likely to become deaf.
Congenital and geriatric deafness as well as deafness due to trauma are often permanent, which means that they cannot be treated. Acquired deafness, due to something like an infection or blocked ear canal, can often be temporary and treatable.
A veterinarian will be able to examine your dog’s ear canal for things like wax accumulation, infections, inflammation, injury, a ruptured eardrum, polyp or foreign object to find out the cause.
The English Cocker Spaniel is 3 times more likely to be deaf in both ears than a multi-colored dog of the same breed. Dalmatians are born deaf in both ears around 22% of the time, and the Australian Cattle Dog is born deaf around 11% of the time.
Jack Ruseel Terriers are deaf at birth around 8% of the time, and while some at-risk breeds will only have deafness in one ear, deafness in both ears is far more common.
What Breeds Of Dogs Are Prone To Deafness?
There are more than 30 breeds of dogs that are known to be at a higher risk of deafness, including the Australian Shepherd, Boston Terrier, Cocker Spaniel, Dalmatian, German Shepherd, Jack Russell Terrier, Maltese, toy and miniature Poodle, and the West Highland White Terrier.
Although, it is typically more common in senior dogs. The following breeds are highly associated with congenital deafness:
Jack Russell Terrier
Australian Cattle Dog
English Cocker Spaniel
Signs That Your Dog Is Deaf
If you have any of the above dog breeds, or any other dog that is more likely to become deaf, then it is important to be aware of the signs that could indicate that they have lost their hearing. Some of the signs that your dog is deaf include being:
- Unresponsive to everyday sounds
- Unresponsive to its name
- Unresponsive to the sounds of squeaky toys
- Not waking up to loud noises
What Causes Deafness In Dogs?
There are quite a few causes of deafness, and we are going to explain them below to help you better understand them.
- Conduction – This is when sound waves do not reach the nerves in the ear, and it can be due to inflammation of the outer ear and other external ear canal diseases, as well as narrowing of the ear canal, the presence of tumors, or a ruptured eardrum.
- Nerve – Degenerative nerve changes in elderly dogs can lead to deafness.
- Anamatonic Disorders – Poor development or a lack of development in the part of the ear that contains the nerve receptors that are used for hearing can lead to a buildup of fluid in specific areas of the brain. This can damage the part of the brain that is used for hearing.
- Inflammatory and Infectious Diseases – Inflammation in the inner ear can cause alterations in hearing, but not complete deafness.
Some of the other things that can cause deafness are:
- Inflammation of the middle ear
- Tumors or cancer involving the nerves used for hearing
- Toxins and Drugs
- Chemotherapy drugs
- Medications to remove excess fluid from the body
- Heavy metals such as arsenic, lead, or mercury
- Products that are used to break down waxy material in the ear canal
Some of the most common risk factors for deafness include long term chronic inflammation of the outer, middle, or inner ear, certain genes, or a white coat color.
Deafness And Coat Color
You might be wondering what the color of your dog’s coat could possibly have to do with their hearing. The genes that control the color of the coat and hearing are actually linked, and genes do sometimes interact this way.
Some breeds of dog will always have the same coloring, like a Dalmation that will always be white with black spots. However, some other breeds can be white or other colors. Dogs with a white coat are more than 8 times more likely to be deaf in both ears than the same breed with another coat color.
How Is Deafness Diagnosed In Dogs?
Your vet can conduct bacterial cultures and hearing tests on your dog and test the sensitivity of the ear canal to diagnose an underlying condition. As we have previously mentioned, there are lots of potential causes of deafness, and each of them will need to be ruled out to find the cause.
Is There Any Treatment For Deafness In Dogs?
If the dog has been born deaf, there is no way to treat them. However, if it has been caused by something like inflammation or an infection, then it is possible to treat your dog and restore their hearing.
Although, this will depend on the extent of their deafness and any damage that might have been caused. Sometimes, hearing aids can be used for dogs to help with their hearing.
