Despite the fact that albinism is uncommon in all animals, including dogs, many people mistake white-coated dogs or those who display forms of albinism for being albino dogs. True albinism is a genetic condition in which the skin, coat, and eyes all lack any pigmentation.
A crucial distinction to make between dogs with white coats and albinos is that the former actually produce the color white, whereas the latter only appear to do so due to pigmentation deficiencies.
Dogs with all-white coats have genetic markers that cause the white pigment to hide or suppress all other colors. On the other hand, albinism results from a lack of both the melanin-producing enzymes and melanin itself. However, some canines display albinism-like traits without actually having the condition. Let’s examine the differences to the best of our ability and see what makes an albino dog an albino dog.
So … Are all white dogs deaf?
Thanks to a unique layer of cells in the inner ear, listening is possible. The stem cells that make up this layer and the cells that determine the color of a dog’s hair come from the same place. Without this stem cell, the dog’s body won’t be able to produce this particular layer of auditory cells and will probably appear white.
Dogs with the piebald gene, which affects the amount and distribution of white color, frequently experience deafness. Piebaldism results from a lack of melanocytes, the cells that produce the melanin pigment. The melanocytes in a dog’s skin are what determine its coloration, including whether it has brown or black hair or blue or brown eyes (blue eyes are not a true eye color; instead, they are the result of a deficiency in the pigment that creates color in the iris). A dog born without melanocytes has a primarily white coat and frequently blue eyes. Breeds like Bull Terriers, Huskies, Boxers, English Setters, and Dalmatians are frequently affected by the piebald gene.
The merlé gene, which gives dogs their mottled fur and blue eyes, is also linked to congenital deafness. Sheepdogs, Teckels, Corgis, and Border Collies are breeds that are frequently impacted by the merlé gene.

Acquired deafness can be caused by numerous factors. Some medications can be toxic to the ears. Although these medications typically result in permanent deafness, some animals may eventually regain their hearing. Many older animals develop deafness. Typically, it begins with a decline in hearing mid- to high-level frequencies and progresses to the point where no frequency can be heard.
How to Spot a Hearing Issue in Your Dog: Usually, dogs who are bilaterally deaf from a young age are simple to spot. They might not respond when you call, be difficult to wake up when they’re sleeping, or not acknowledge you when you get home.
Neuroepithelial deafness is not associated with coat patterns. It typically affects both ears and appears at roughly the same age.
Dogs that develop hearing loss unilaterally or later in life may be harder to diagnose. A dog with only one deaf ear may have trouble determining where a sound is coming from and will usually turn toward the hearing ear.
Can a deaf dog hear a dog whistle?
Some dogs who would normally be deaf can hear specific frequencies, like a loud dog whistle. Use this whistle and encourage your dog to respond if he is fortunate enough to have this level of hearing.
FAQ
What percentage of all white dogs are deaf?
The majority (96. White coats (with or without patches) were present on 29 percent of deaf puppies; 19 puppies with white coats (with or without a patch) were deaf in 29% of them.
Why are white dogs deaf or blind?
Dogs with the piebald gene, which affects the amount and distribution of white color, frequently experience deafness. Piebaldism results from a lack of melanocytes, the cells that produce the melanin pigment.
Are white dogs more likely to be deaf?
Genetic factors, which account for the majority of congenital hearing loss, have been linked to specific coat colors. The coat colors associated with the highest risk are: white.
Are all white dogs blind?
White and albino dogs are not necessarily more likely to be born blind or deaf because the genes responsible for coat color, eye and ear health are not causally linked, similar to how white cats.
