The captivating phenomenon of a dog sporting two distinct eye colors, known as **heterochromia**, is a fascinating and often admired trait. This intriguing visual quirk has sparked curiosity and sparked countless conversations among dog enthusiasts. While some might attribute it to mere coincidence, the truth lies in a more profound biological phenomenon that plays out during the development of a dog’s eyes.
The amount of melanin in the iris, the colored part of the eye, determines the color of a dog’s eyes. Melanin is a pigment that also gives color to skin and hair. Heterochromia occurs when melanin is uneven in the irises, making one eye a different color.
