The reason why native dogs have blue eyes is due to the specific genes they inherit. Generally, this specific gene will make their pupils blue, causing their eyes to turn blue.
When the eyes do not have melanin, we will see the blue color reflected and refracted on the dog's iris. As the dog grows up, melanin begins to be produced in the iris, and it is the pigment precipitation formed by melanin that makes the dog's eyes eventually appear in different colors.
Albino dogs, you will find that their eyes are white, pink or even red. White is the effect of lighting.
As for pink and red, they come from capillaries in the eyes of dogs. These blood vessels are usually covered by the color formed by melanin, and are only visible in the eyes of dogs lacking melanin.
