Why is heterochromia so common in dogs?
Heterochromia is caused due to uneven melanin distribution and inbreeding. It occurs in many other breeds of dogs (Australian Shepherd would probably be right behind the Husky), cats, and horses. Heterochromia is caused due to uneven melanin distribution and inbreeding.
Can purebred dogs have different colored eyes?
Heterochromia is the scientific term for eyes that are two different colors. It not only occurs in dogs but also affects cats, horses and occasionally even people. In dogs with heterochromia, the lack of melanin causes one of their eyes to appear blue or bluish-white.

What is the rarest eye color for dogs?
While two-toned eyes are certainly striking, there is no need to be alarmed. The condition is genetic and there is generally no need to worry. But dogs with heterochromia might also be linked to glaucoma, so if you suspect that there might be something wrong, definitely talk to your vet about all concerns.

Is partial heterochromia rare?
Though common in some breeds of cats, dogs, cattle and horses, due to inbreeding, heterochromia is uncommon in humans, affecting fewer than 200,000 people in the United States, and is not associated with lack of genetic diversity.
Why does my dog have a half blue eye?
Causes of Heterochromia in Dogs Heterochromia is caused by a lack of the pigment melanin in all or part of one eye. In dogs with heterochromia, the lack of melanin causes one of their eyes to appear blue or bluish-white. Heterochromia in dogs is often hereditary, meaning it is passed through their genetic makeup.
What causes partial heterochromia?
What causes partial heterochromia? Partial heterochromia can happen genetically, because of an underlying condition or due to the use of certain medication. Genetically, partial heterochromia can happen at birth or as the melanin in the iris develops throughout childhood.
Is heterochromia more common in dogs?
Generally, heterochromia is more common in dogs with dappled, merle or white coloring around their heads. Heterochromia iridis occurs most frequently in huskies, dalmatians, and Australian shepherds and cattle dogs. The other breeds are more prone to the other two types of heterochromia.
Is heterochromia in dogs from inbreeding?
Though common in some breeds of cats, dogs, cattle and horses, due to inbreeding, heterochromia is uncommon in humans, affecting fewer than 200,000 people in the United States, and is not associated with lack of genetic diversity.
How rare are dogs with different colored eyes?
However, acquired heterochromia can occur due to many different conditions, meaning it is impossible to tell if they will develop the condition. Acquired heterochromia is unlikely to affect the eye completely, so having a dog with eyes of two different colors is very unlikely unless they were born like that

Can heterochromia cause problems?
Most of the time, it doesn’t cause any problems. It’s often just a quirk caused by genes passed down from your parents or by something that happened when your eyes were forming. In rare cases, it can be a symptom of a medical condition. Heterochromia is common in some animals but rare in humans.
Is heterochromia a bad mutation?
The mutation is benign, meaning that it doesn’t relate to an underlying disease or illness and won’t cause any harm. This random genetic surprise affects the melanin levels on different parts of the iris(es). Of the common eye colors, brown eyes have the most melanin and blue eyes have the least.
Are heterochromia eyes bad?
Research suggests that most cases of heterochromia in humans are benign and occur without any underlying abnormality. According to the Genetic and Rare Diseases Information Center, most cases of heterochromia of the eye occur sporadically in people with no family history of the condition.
