Heterochromia in dogs is known as "heterochromia of the iris" or simply "iris heterochromia." This condition occurs when one eye has a different color from the other due to variations in melanin production.
What is heterochromia called in dogs? - in detail
Heterochromia, a condition characterized by the presence of two different eye colors, is not uncommon among dogs. In canines, this phenomenon is known as "complete heterochromia" or "partial heterochromia," depending on the extent and distribution of color differences in the eyes.
Complete heterochromia refers to a situation where one eye is entirely different in color from the other. This condition is relatively rare in dogs but can be observed in certain breeds such as Siberian Huskies, Australian Shepherds, and Border Collies. The causes of complete heterochromia can vary from genetic factors to ocular diseases or injuries that affect the eye's pigmentation.
Partial heterochromia, on the other hand, is more frequently seen in dogs. In this case, only a part of one or both eyes displays a different color. This condition can be further categorized into sectoral and central heterochromia. Sectoral heterochromia involves a specific segment of the iris showing a distinct color, often due to genetic factors or developmental abnormalities. Central heterochromia affects the center of the iris, which may appear lighter or darker than the surrounding area.
While heterochromia is generally considered a benign condition in dogs and does not typically affect their vision or overall health, it is essential to consult with a veterinarian if you notice any sudden changes in your dog's eye color. Such changes could indicate an underlying ocular issue that requires medical attention. Regular veterinary check-ups can help ensure the well-being of your pet and provide peace of mind regarding their eye health.
