Why do some dogs have blue eyes?

Today we are going to talk specifically about this topic. We will also show you the most popular blue-eyed dog breeds. Of course, it is important to understand why some dogs have blue eyes, and some do not.

It should be noted that this characteristic of blue eyes is present in many breeds. We can mention, for example, the English shepherd, dachshunds, or the Border collie. For these breeds, blue eyes are a recessive trait.

A genetic mutation causes blue eyes in dogs.

This means that two genetic variants must be present for a dog to have blue eyes. Multiple research has shown that these genetic variants are related to coat color.

More specifically, with the merle color shades. That is to say, spots of mottled color. Also, with the white coat with colored spots. However, these genes alone are not the cause of blue eyes in Siberian Eskimos or Australian Shepherds.

To find the underlying cause of blue eyes in dogs. The researchers compared more than 214,000 genetic markers from more than 3,180 dogs. Both purebred and mixed breed dogs were included.

The research revealed two important associations with blue eyes. The first has to do with canine chromosome 10. That is, the gene related to the merle color pattern.

The other link was found at a position on chromosome 18, which had not been described before. Upon closer investigation, the scientists discovered a duplicated fragment of genetic material.

This fragment was in close proximity to a gene that is considered to be critical in eye development. A DNA analysis of 2,890 dogs confirmed the strong link between the genetic mutation and blue eyes in dogs.
