Dogs with blue eyes have always held a certain mystique, capturing our attention with their piercing stare. But what causes this striking eye color, and which breeds are known for it? This article dives deep into the world of blue-eyed dogs, exploring the genetics behind their captivating gaze, highlighting popular breeds, and addressing potential health concerns.
Decoding the Genetics of Blue Eyes in Dogs
The science behind blue eyes in dogs is fascinating. While brown eyes are the most common, blue eyes arise from variations in canine genetics. One primary cause is the merle gene, which dilutes pigment and can lead to mottled coats and blue eyes, often one or both. Another contributing factor is the absence or reduced amount of melanin, the pigment responsible for eye color. This lack of pigment can result in blue eyes, especially in breeds with white or light-colored coats.
Is the Merle Gene Always Responsible for Blue Eyes?
Not always. Some breeds, like the Siberian Husky and the Australian Shepherd, can have blue eyes without the merle gene. In Huskies, a gene near the ALX4 gene on canine chromosome 18 is associated with blue eye color. This emphasizes the complexity of canine genetics and the multiple factors that influence eye pigmentation.

Popular Dog Breeds with Blue Eyes
Several breeds are known for their mesmerizing blue eyes. Some of the most popular include the Siberian Husky, known for its striking blue or bi-colored eyes; the Australian Shepherd, another breed often exhibiting blue eyes, sometimes paired with different colored eyes; the Weimaraner, a graceful hunting breed with piercing blue eyes; and the Dalmatian, occasionally boasting blue eyes, though it’s less common.
What About Other Breeds?
While less prevalent, blue eyes can appear in other breeds too, such as the Border Collie, Shetland Sheepdog, and even the Dachshund. This can often be due to the merle gene or other genetic factors influencing coat and eye color.
Health Considerations for Blue-Eyed Dogs
While blue eyes are undeniably beautiful, it’s important to be aware of potential health concerns. Dogs with the merle gene, especially “double merles” (resulting from breeding two merle dogs), are at increased risk for deafness and blindness. Additionally, dogs with blue eyes, particularly those with a lot of white on their face, can be more sensitive to sunlight and prone to sunburn.
How to Protect a Blue-Eyed Dog’s Vision
If you have a blue-eyed dog, regular veterinary checkups are crucial. Protecting their eyes from excessive sunlight is also essential. Consider using dog-specific sunglasses or limiting their exposure to bright sunlight during peak hours.

Do All White Dogs Have Blue Eyes?
No, not all white dogs have blue eyes. While a white coat can sometimes be associated with blue eyes, many white dogs have brown or even hazel eyes. The coat color and eye color are influenced by separate genetic mechanisms. For more on coat colors, you might find our article on [what type of dogs have blue eyes] helpful.
