Genetics of Heterochromia
Heterochromia, the condition that causes dogs to have different colored eyes, is a result of a genetic mutation that affects the production of melanin, the pigment that gives eyes their color. Melanin is produced by cells called melanocytes, and the amount and distribution of these cells determine the color of a dog's eyes. In dogs with different colored eyes, one eye may have more melanocytes than the other, resulting in different eye colors.
Impact on Health
While heterochromia is generally not a health concern for dogs, it's important to note that certain eye conditions, such as uveitis or glaucoma, can cause heterochromia as a symptom. If you notice any changes in your dog's eye color or behavior, it's essential to consult with a veterinarian to rule out any underlying health issues.
