The Australian Shepherd, commonly referred to as the Aussie, is a breed known for its intelligence, agility, and striking appearance. One of the most distinctive features of the Aussie is its eye color, which can vary greatly among individuals. Red Aussies, in particular, have garnered attention due to their unique coat color and the potential for blue eyes. In this article, we will delve into the genetics behind eye color in Red Aussies and explore whether they can indeed have blue eyes.
Understanding Australian Shepherd Genetics
To comprehend the possibility of blue eyes in Red Aussies, it’s essential to understand the basics of genetics that influence coat color and eye color in this breed. The Australian Shepherd’s coat color is determined by multiple genes, but the primary genes responsible are the melanocortin 1 receptor (MC1R) and the agouti signaling protein (ASIP). These genes interact to produce the various coat colors seen in Aussies, including black, blue merle, red merle, and red.
Genetics of Eye Color
Eye color in dogs is determined by the amount and distribution of pigment in the iris. The genetics of eye color are complex and involve multiple genes. However, the basic principle is that more pigment results in darker eye colors, such as brown, while less pigment can lead to lighter eye colors, including blue. The interaction between genes that control the production and distribution of melanin (the pigment responsible for eye color) determines the final eye color of a dog.
Pigmentation and Eye Color
In dogs, the pigmentation that affects eye color is controlled by genes that determine the amount of eumelanin (black and dark brown pigment) and pheomelanin (red and yellow pigment) produced. The combination and interaction of these pigments influence the eye color. Blue eyes in dogs are the result of a lack of pigmentation in the iris, allowing the light to scatter and give the appearance of blue.
Red Aussies and Blue Eyes
Red Aussies, with their distinctive red coat, can have a variety of eye colors, including blue. The genetics that determine the red coat color do not directly influence the eye color, meaning that a Red Aussie can have blue eyes if it inherits the genetic combination that results in reduced pigmentation in the iris.
Merle Genetics and Eye Color
It’s worth noting that the merle gene, which can produce a mottled coat pattern, also affects eye color. Merle Aussies, including red merles, have a higher incidence of blue eyes due to the interaction of the merle gene with the genes that control pigmentation. However, not all Red Aussies with blue eyes are merle; they can be non-merle reds that simply inherit the genetic factors leading to blue eyes.
Health Considerations
While blue eyes can be a beautiful and desirable trait in Red Aussies, it’s crucial to consider the health implications. Dogs with blue eyes, especially those that are heavily pigmented in other areas, can be more prone to certain health issues, such as deafness or vision problems, due to the genetic factors that influence pigmentation. Responsible breeding practices prioritize health and genetic diversity to minimize these risks.
Conclusion on Red Aussies and Blue Eyes
In conclusion, Red Aussies can indeed have blue eyes, depending on the genetic factors they inherit. The interaction of genes that control coat color and eye pigmentation determines the final eye color of a Red Aussie. While blue eyes can be a stunning feature, it’s essential for breeders and owners to prioritize the health and well-being of these dogs, ensuring that genetic diversity and health considerations are at the forefront of breeding decisions.
Given the complexity of genetics and the potential health implications, associated with certain traits, ongoing research and education are vital for the betterment of the breed. For those interested in Red Aussies with blue eyes, understanding the genetics and health considerations can help in making informed decisions, whether as a breeder, owner, or enthusiast of the Australian Shepherd breed.

What is the origin of the Red Australian Shepherd breed?
The Red Australian Shepherd, also known as the Red Aussie, is a variation of the Australian Shepherd breed. The breed originated in the United States in the 19th century, where it was developed to herd sheep and other livestock. The Red Aussie is a result of selective breeding to produce a dog with a distinctive red coat color. This breed is highly intelligent, energetic, and loyal, making it a popular choice as a working dog and a family pet.
The Red Aussie’s ancestry can be traced back to the Basque region of Europe, where the ancestors of the breed were used to herd sheep. The breed was later developed in the United States, where it was crossed with other breeds such as the Border Collie and the Kelpie to produce a dog with the desired characteristics. Today, the Red Aussie is recognized as a distinct breed by many kennel clubs and breed associations, and it is prized for its intelligence, agility, and loyalty.
Do all Red Aussies have blue eyes?
Not all Red Aussies have blue eyes. While blue eyes are a common feature of the breed, they are not universal. Some Red Aussies may have brown eyes, amber eyes, or even eyes with a combination of colors. The eye color of a Red Aussie is determined by genetics, and it can vary depending on the individual dog’s ancestry and breeding. However, blue eyes are a distinctive feature of the breed, and many Red Aussies do have this striking eye color.
The genetics of eye color in Red Aussies are complex, and they involve multiple genes that interact to produce the final eye color. The blue eye color is caused by a lack of pigment in the iris, which allows the light to scatter and give the appearance of blue. However, other genes can influence the expression of the blue eye color, resulting in a range of eye colors and patterns. As a result, while blue eyes are common in Red Aussies, they are not the only eye color found in the breed.
What causes blue eyes in Red Aussies?
Blue eyes in Red Aussies are caused by a genetic variation that affects the production of pigment in the iris. The iris is the colored part of the eye, and it contains cells called melanocytes that produce pigment. In dogs with blue eyes, the melanocytes are either absent or not functioning properly, which allows the light to scatter and give the appearance of blue. This genetic variation is inherited from the parents, and it can be influenced by multiple genes that interact to produce the final eye color.
The genetics of blue eyes in Red Aussies are not fully understood, and more research is needed to determine the exact mechanisms that control eye color in the breed. However, it is known that blue eyes are a recessive trait, meaning that a dog must inherit two copies of the gene (one from each parent) to express the trait. This means that even if a Red Aussie has blue eyes, it may still carry genes for other eye colors, which can be passed on to its offspring.
Are blue eyes in Red Aussies associated with any health problems?
Blue eyes in Red Aussies are not typically associated with any health problems. However, as with any breed, Red Aussies can be prone to certain health issues, such as hip dysplasia, elbow dysplasia, and eye problems like cataracts and progressive retinal atrophy. These health issues are not directly related to the blue eye color, but rather to the breed as a whole. Responsible breeding practices, such as genetic testing and health clearances, can help to minimize the risk of these health problems.
It’s worth noting that some breeds with blue eyes, such as the Siberian Husky, can be prone to health issues like deafness and blindness. However, this is not typically the case with Red Aussies, and the breed is generally considered to be healthy and robust. As with any breed, it’s essential to work with a reputable breeder who prioritizes health and temperament, and to have your dog regularly checked by a veterinarian to ensure its overall health and well-being.
Can Red Aussies with blue eyes see normally?
Yes, Red Aussies with blue eyes can see normally. The blue eye color does not affect the dog’s vision, and dogs with this eye color can see just as well as dogs with other eye colors. The structure of the eye, including the retina and the optic nerve, is not affected by the blue eye color, and dogs with blue eyes can detect movement, see colors, and navigate their surroundings with ease.
In fact, Red Aussies are known for their exceptional vision and agility, which makes them well-suited to tasks like herding and agility training. Their eyes are adapted to detect movement and changes in their surroundings, which allows them to respond quickly and accurately to their environment. Whether a Red Aussie has blue eyes or another eye color, its vision is not affected, and it can see and interact with its surroundings in a normal and healthy way.
How common are blue eyes in Red Aussies?
Blue eyes are relatively common in Red Aussies, but they are not universal. The breed standard for the Australian Shepherd, which includes the Red Aussie, allows for a range of eye colors, including blue, brown, and amber. However, blue eyes are a distinctive feature of the breed, and many Red Aussies do have this eye color. According to some estimates, up to 50% of Red Aussies may have blue eyes, although this can vary depending on the individual dog’s ancestry and breeding.
The prevalence of blue eyes in Red Aussies can vary depending on the breeder and the bloodlines used. Some breeders may prioritize blue eyes as a desirable trait, while others may focus on other characteristics like intelligence, agility, and temperament. As a result, the frequency of blue eyes in Red Aussies can vary, and it’s essential to work with a reputable breeder who prioritizes the overall health and well-being of the dogs, rather than just focusing on a specific eye color.
Can I breed a Red Aussie with blue eyes to get more puppies with blue eyes?
Yes, you can breed a Red Aussie with blue eyes to increase the chances of getting puppies with blue eyes. However, the genetics of eye color are complex, and the outcome is not guaranteed. Blue eyes are a recessive trait, meaning that a dog must inherit two copies of the gene (one from each parent) to express the trait. If you breed a Red Aussie with blue eyes to another dog that carries the gene for blue eyes, you may increase the chances of getting puppies with blue eyes.
However, it’s essential to remember that breeding dogs is a complex process that involves many factors beyond just eye color. Responsible breeding practices prioritize the overall health, temperament, and well-being of the dogs, rather than just focusing on a specific trait like eye color.
