What do blue eyes in dogs mean?

Blue eyes are frequently the consequence of the merle gene, which is linked to dog coat color and dilutes the pigment in the iris of the eyes, turning them blue.
A rare gene known as ALX4 on canine chromosome 18 that allows one or both eyes to be blue is another reason for genetically blue eyes in dogs.
It is distinct from coat coloring and causes one or both eyes to be blue.
This occurs when cells are unable to produce pigment, resulting in pigment-lacking colors like green, grey, and blue eyes.
Many pups are born with blue eyes; some puppies maintain their blue eyes until they reach adulthood, while others have dark eyes; It can take between 9 to 16 weeks for some puppies to reach their mature eye color.
Certain breeds are more prone to it. Blue eyes are more probable in animals with greater pigment dilution on their hair and skin. You can learn if Golden Retrievers can have blue eyes here.

Blue eyes can also be caused by a variety of illnesses and eye problems. Canine hepatitis, for example, is a preventable but fatal disease that affects numerous organ systems and causes the corneas to turn blue.
