What is Heterochromia in Dogs? A Guide to Understanding Your Pet’s Eye Color


Heterochromia is a genetic trait that can be seen in dogs. It’s an uncommon but intriguing phenomenon where a dog’s eyes have different colors. Many people have misconceptions about heterochromatic dogs, and this post will help clear up some of these misunderstandings.


The condition is caused by the distribution of melanin in the iris of each eye. Melanin determines the color of the eye, and when it isn’t distributed evenly in both eyes, heterochromia occurs. For example, if one eye has more melanin than the other, it will be darker than its counterpart creating a unique appearance for your furry friend.

Celebrity Heterochromatic Dogs

Many famous dogs are known for their beautiful mismatched eyes, such as Bowie (a Siberian Husky), Mila Kunis’ dog (a mixed breed), and Kate Bosworth’s pup named Happy (Australian Shepherd). These pups’ one-of-a-kind looks make them stand out from their pack.

Treatment or Concerns?

Generally speaking there is no need for concern or treatment required with regards to heterchromatic coloring because it does not affect vision nor cause any health issues; however, if you notice any changes to your pup’s vision or behavior alongside changes to their pigmentation then we recommend contacting your veterinarian immediately.


Now that you know what causes this unique characteristic and how common it is among certain breeds let yourself appreciate just how special our four-legged friends can truly be! Remember that having different colored eyes doesn’t make them less capable or healthy- quite the opposite: they’re extra special indeed!
