You’ve probably heard the term “albino” before in reference to humans who lack pigment in their eyes, skin, and hair. But did you know that dogs can have this genetic condition too? While not all white dogs are albino, there are instances of completely albino dogs, and more commonly, dogs who have some degree of genetic condition. Read on to learn about the causes of albinism and what you can do to care for an albino dog.
What Causes Albinism?
A completely pure white animal with pink eyes and pale pink skin is considered albino and is technically referred to as tyrosinase-negative. Tyrosinase is an enzyme involved in melanin production, and melanin is the natural substance that gives color (or pigment) to the eyes, skin, and hair. Albinism is a lack or defect of this enzyme and is caused by a recessive gene that is inherited from both parents. Many true albino dogs will suffer from deafness because the unpigmented skin in the ear canal causes the nerve endings to degenerate.
Other Forms of Albinism
Other forms of albinism -- referred to as tyrosinase-positive -- result in a dog that exhibits whitening but does have pigment. White German Shepherds, West Highland White Terriers, and White Doberman Pinschers are some of the breeds considered to be tyrosinase-positive. While these dogs may appear to be all white, they are actually either a pale cream or very light gray color.
Other dogs may inherit genes that create unique coat patterns caused by a lack of pigmentation. Merle is one of these genes and patterns and often shows up in Australian Shepherds, Shetland Sheepdogs, Corgis, Dachshunds, Collies, Great Danes, and others. What looks like spots are actually patches of the original coat color showing up within the lightened base coat. This is caused by either one or two inherited copies of the Merle gene (dogs with two copies may show more Merling and may also have more white in their coat).
The Harlequin gene often shows up in Great Danes who carry the Merle gene. This results in a coat that is significantly lightened from its original color, with splotches of the original color still showing through. These dogs sometimes appear to be white with black spots.
Still, more patterns caused by lack of pigmentation include Irish Spotting and Piebald Spotting. Irish Spotting is often seen in Collies and refers to the white area on the chest, legs, and face. This pattern is also seen in the Boston Terrier and other dogs. Piebald Spotting is common to Cocker Spaniels, Bulldogs, Beagles, and other hounds. It is characterized by random white spotting.
How Common Is Albinism?
True albino dogs with no pigment at all are extremely rare. Dogs with some degree of albinism are much more common, especially for the breeds listed above.
Caring For an Albino Dog
True albino dogs are those who are not able to produce any melanin, which is a compound that gives color to the skin, eyes, and hair. Melanin also protects the skin from sun radiation, and therefore albino dogs are highly susceptible to sunburn and cancer of the skin and eyes. You can protect your albino dog by keeping them out of the sun, applying sunscreen, and dressing them in protective gear, including dog sunglasses/goggles.
Frequently Asked Questions
Are albino dogs rare?
Yes, albino dogs are rare. Albinism is a genetic condition that causes a lack of pigmentation in the skin, hair, and eyes. This condition occurs when there is a mutation in the gene that controls the production of melanin, the pigment that gives color to the skin, hair, and eyes. Because albinism is a rare genetic condition, albino dogs are also relatively rare.
Do albino dogs have health issues?
Albino dogs, like other animals with albinism, can have a number of health issues related to their lack of pigmentation. Albino dogs have no pigmentation in their iris, which makes their eyes highly sensitive to light. This can cause discomfort and even pain and can lead to issues with vision over time. Also, they have no pigmentation in their skin, which makes them highly susceptible to sunburns and skin cancer. Albino dogs often have poor vision because their eyes lack pigmentation in the iris, which makes it difficult for them to control the amount of light entering the eye. This can lead to issues such as nystagmus and strabismus. Albinism is a genetic disorder, and albino dogs may have a higher risk of developing other genetic disorders. But, not all albino dogs will develop these health issues. Regular vet checkups and providing them with appropriate protection from sun exposure can help minimize health risks.
How can I tell if my puppy is albino?
There are several ways to tell if your puppy is albino. Albino dogs have a completely white or very light coat with no pigmentation. Albino dogs have very light or pink eyes, as they lack the pigmentation in their iris that gives eyes their typical color. Albino dogs have very light or pink skin, as they lack the pigmentation that gives skin its typical color. Some dog breeds have a higher incidence of albinism, and genetic testing can confirm if your puppy has the genetic mutation that causes albinism. Also, some breeds, such as the Great Dane, the Bulldog, or the Boxer, have a coat color variant called "albino," but in this case, it is not due to a lack of pigmentation but due to a lack of color. These dogs should not be confused with true albinos.
Are albino dogs deaf and blind?
Albinism is a genetic condition that affects the production of melanin, a pigment that gives color to the skin, hair, and eyes. In dogs, albinism can cause a lack of pigmentation in the eyes, which can lead to vision problems, but it is not always the case. Some albino dogs may have normal vision, while others may be partially or completely blind. Similarly, albinism in dogs is not directly associated with deafness, although some albinos may have hearing impairments due to associated genetic factors. The best way to know if a dog is blind or deaf is to have them examined by a veterinarian.
Can albino dogs go outside?
Albino dogs, like all dogs, can go outside and enjoy the outdoors. However, because albinism affects the production of melanin, which helps protect the skin from UV radiation, albino dogs may be more susceptible to sunburn and skin cancer. It is important to protect them from prolonged exposure to direct sunlight, especially during the middle of the day when the sun's rays are the strongest. You can use sunscreen specifically formulated for dogs, keep them in the shade, or limit their time outside during the hottest parts of the day. Additionally, albino dogs may have vision problems, so it's important to supervise them when outside to ensure their safety.
