Understanding Canine Eye Color
A dog’s eye color, like in humans, is determined by the amount and type of pigment called melanin produced by specialized cells called melanocytes. Melanin is responsible for the coloration of the iris, the colored part of the eye. More melanin results in darker colors like brown or black, while less melanin leads to lighter colors like blue or green. why do my eyes see colors differently. There are also genetic factors that influence how this pigment is distributed and expressed.
Puppy Eye Color Changes
Most puppies are born with blue eyes because melanin production hasn’t fully kicked in yet. As they grow, melanocytes become more active, gradually increasing the amount of pigment in the iris. This is why many puppies’ eye color changes over the first few months of life, usually settling into their adult color by around 6 to 8 weeks, though it can sometimes take longer, even up to a year in some breeds. This change can be quite dramatic, transforming from a light blue to a deep brown, or sometimes even a striking green or amber. You might find yourself asking, when do dogs eyes change color?

Medical Reasons for Eye Color Change
While eye color changes in puppies are normal, changes in adult dogs can sometimes signal an underlying medical condition.

If you notice any sudden changes in your dog’s eye color, accompanied by other symptoms like redness, cloudiness, discharge, or squinting, it’s crucial to consult a veterinarian immediately.
Heterochromia in Dogs
Some dogs are born with heterochromia, a condition where each eye is a different color.

While a balanced diet is crucial for overall health, including eye health, it won’t change the color of the iris. A healthy diet ensures the proper functioning of the eyes and can help prevent certain eye conditions, but it doesn’t impact melanin production in a way that would alter eye color.
