Have you ever noticed your furry friend’s eyes seeming to shift hues? Why Do Dogs Eyes Change Color? It’s a fascinating phenomenon that many dog owners observe. This article delves into the reasons behind canine eye color changes, exploring the science, common causes, and when to seek veterinary attention.
Understanding Canine Eye Color
A dog’s eye color is determined by the amount and type of pigment, called melanin, present in the iris. Just like in humans, this pigment can vary, leading to a range of eye colors from deep brown to light blue, and even green or amber. Can dogs eye color change over time? Yes, and the reasons are varied. Sometimes, the change is perfectly normal, while other times it could signal an underlying health issue. What color eyes do coyotes have at night, for example, might be influenced by different factors than domestic dogs.
Common Reasons for Eye Color Change in Dogs
Puppy Development
One of the most common reasons for eye color change occurs during puppyhood. Puppies are often born with blue eyes that gradually darken as they mature. This is due to the production of melanin increasing over the first few months of life. The final eye color usually stabilizes by the time a puppy is around six months old. Do dogs eye color change after this period? It’s less common, but still possible.
Heterochromia
Some dogs are born with heterochromia, a condition where each eye is a different color. This can be a striking and beautiful feature, often seen in breeds like Huskies and Australian Shepherds. Heterochromia is usually harmless and doesn’t affect vision. It’s simply a unique quirk of pigmentation.

Medical Conditions
While many eye color changes are benign, some can be indicative of underlying medical conditions. These include:
- Uveitis: Inflammation of the uvea, the middle layer of the eye, can cause redness, pain, and changes in pupil size and color.
- Glaucoma: Increased pressure within the eye can sometimes lead to a change in eye color, often accompanied by cloudiness or a bluish haze.
- Nuclear Sclerosis: This is a normal age-related change in the lens of the eye, causing it to appear slightly cloudy or bluish. It’s important to distinguish this from cataracts, which are more opaque and significantly impact vision.
- Injuries: Trauma to the eye can cause changes in color, often accompanied by other symptoms like bleeding or swelling.
Medications
Certain medications can also affect eye color, although this is rare. If you notice a change in your dog’s eye color after starting a new medication, consult your veterinarian.
When to See a Vet
If your dog’s eye color changes suddenly or is accompanied by other symptoms such as redness, discharge, pain, cloudiness, or changes in vision, it’s essential to seek veterinary attention immediately. These could be signs of a serious eye condition requiring prompt treatment. Think about what color do you see when you close your eyes? If your dog is experiencing visual disturbances, they may perceive the world differently.
Conclusion
Changes in a dog’s eye color can be a normal part of development, a unique genetic trait, or a sign of an underlying health issue. By understanding the various causes and knowing when to seek professional advice, you can ensure your furry companion’s eye health and overall well-being. Why do dogs eyes change color? Now you know!
