Why do dogs have different colored eyes?

This phenomenon is called heterochromia. Heterochromia is a difference in eye, hair, or skin color. It occurs due to an excess or lack of melanin.

In this case, it happens that the eyes of dogs have different colors, and it happens that the iris of one eye is painted in different colors. For example, a brown eye may have blue patches.

There are different types of eyes in both animals and humans. It can be a congenital or acquired feature.

Among dogs, mismatched eyes are most commonly seen in Border Collies, Huskies, Shelties, Collies, and Australian Shepherds. Other breeds and mestizos are less likely to boast this trait.

Is it dangerous if a dog has different eyes?

If different eyes are an inborn feature of a dog, then most often this is not dangerous and does not affect vision.

But it happens that the color of the dog’s eyes changes due to illness or injury. And this, of course, cannot be ignored. It is worth contacting a veterinarian who will establish the cause of the “disagreement” and, if necessary, prescribe treatment.
