Rare Coat Colors
While Australian Shepherds are known for their striking coat colors, there are a few rare colors that are less commonly seen within the breed. Let’s explore these unique coat colors: solid black, yellow, and white Australian Shepherds.
Solid Black Australian Shepherd
Solid black Australian Shepherds are considered rare in the breed. The solid black coat color is a result of a recessive gene, which means the pup must inherit the solid black gene from both parents. These dogs have rich black fur all over their faces and bodies, along with black noses, mouths, claws, and paw pads. While most Australian Shepherds have white or tan markings, the solid black coloring is distinct and less common. It’s important to note that solid black Australian Shepherds typically have dark brown eyes, although amber eyes can also occur.

Yellow Australian Shepherd
Yellow Australian Shepherds, also known as light cream, are another non-standard coat color that is considered rare. These dogs have a light cream coat color and dark noses. Yellow Aussies are often carriers of a cryptic merle gene, which means they have the potential to produce merle puppies if bred with a merle Australian Shepherd. Breeding two merle dogs is typically discouraged due to the potential health issues it can cause, making yellow Australian Shepherds non-standard and unrecognized by kennel clubs.

White Australian Shepherd
White Australian Shepherds are also considered rare within the breed. These dogs have a predominantly white coat color, often with patches of color on their faces and bodies. The white coloration is caused by a combination of genetic factors, including the presence of certain alleles. It’s important to note that white Australian Shepherds can sometimes have a higher risk of deafness and eye defects, which is why responsible breeding practices are crucial to minimize these health concerns (Breed Atlas).

Genetic Factors in Coat Color
The coat color of Australian Shepherds is predominantly determined by genetic factors, with genes playing a crucial role in the production and distribution of pigments that contribute to the coloration of their coats (TryFi Blog). Understanding the influence of these genes is key to unlocking the mystery behind the variety of coat colors seen in Australian Shepherds. Let’s explore some of the genetic factors involved:
Influence of Genes on Coat Color
Coat color in Australian Shepherds is controlled by a combination of multiple genes. These genes determine the presence, distribution, and intensity of pigments responsible for the coat colors and patterns observed in the breed. While the specific genes involved are still being studied, they have a significant impact on the appearance of Australian Shepherd coats.
Impact of Merle Gene
One of the most well-known genes that affect Australian Shepherd coat color is the merle gene. The merle gene is an incomplete dominant gene, meaning that its expression is not fully dominant over other coat color genes. A dog carrying one copy of the merle gene (heterozygous) will exhibit the characteristic merle coat pattern, while a dog with two copies of the merle gene (homozygous) may have serious eye defects and could be deaf. It’s important to note that breeding two merle Australian Shepherds together can result in a higher likelihood of producing offspring with these health issues.
Tan Points and Agouti Gene
Another gene that influences coat color in Australian Shepherds is the agouti gene. This gene has different versions, or alleles, that determine the distribution of pigments on the dog’s coat. Most Australian Shepherds have two copies of the tan version of the agouti gene, resulting in the presence of tan points on the coat. However, some individuals may have two copies of the recessive version of the gene, which leads to the absence of tan points. Additionally, the gene K can also influence the presence of tan trim in Australian Shepherds.
Understanding the genetic factors at play helps explain the wide range of coat colors and patterns observed in Australian Shepherds. It’s important for breeders and owners to be aware of these genetic influences to make informed decisions regarding breeding programs and to ensure the overall health and well-being of the breed.

Health Concerns and Coat Colors
When it comes to Australian Shepherds, certain coat colors can be associated with specific health concerns. It’s important for dog owners to be aware of these potential issues to ensure the well-being of their pets. In this section, we will discuss the health concerns related to double merle dogs, deafness and eye defects, and the connection between white markings and deafness.
Double Merle Dogs
Dogs that have two copies of the merle gene, known as “double merles,” are at higher risk for health issues. The merle gene causes changes in cells that arise in melanocytes (pigment cells) during development, leading to a reduction of pigment. Double merles virtually always have abnormally developed eyes, which frequently lead to blindness. Additionally, they may be deaf due to a lack of pigment in the inner ear. It’s important for breeders and owners to be cautious when breeding or adopting double merle dogs to minimize the risk of these health concerns.
Deafness and Eye Defects
The merle gene in Australian Shepherds can also contribute to deafness and eye defects. Dogs with two copies of the merle gene can have cells with no pigment at all, which can result in deafness when located in the inner ear. The lack of pigment in the inner ear affects the development and function of the auditory system, leading to hearing loss. Moreover, abnormal development may occur in various tissues within the eye, which can result in vision impairments. Regular veterinary check-ups and specialized care are essential for managing these conditions and ensuring the overall well-being of affected Australian Shepherds.
White Markings and Deafness
In Australian Shepherds, white markings on or around the ears are associated with deafness. Similar to the mechanism of deafness in double merles, this is due to a lack of pigment in the inner ear. The absence of pigment affects the proper functioning of the auditory system, resulting in hearing impairment (Australian Shepherd Health & Genetics Institute). It’s important to note that this form of deafness is caused by a different genetic factor than the merle gene. Therefore, Australian Shepherds with white markings should be monitored for potential hearing issues and receive appropriate care as needed.
Understanding the potential health concerns associated with specific coat colors in Australian Shepherds is crucial for responsible breeding and pet ownership. Regular veterinary care, proper socialization, and specialized training can help mitigate the impact of these health concerns. If you are considering getting an Australian Shepherd, it’s advisable to consult with reputable breeders or rescue organizations to ensure that your pet’s health and well-being are prioritized.

Breed Standards and Colors
When it comes to Australian Shepherds, there are specific breed standards set by kennel clubs to define acceptable coat colors. These standards ensure consistency and help maintain the breed’s unique characteristics. In this section, we will explore the acceptable colors by kennel clubs, unacceptable colors and patterns, as well as the dominance of coat colors within the Australian Shepherd breed.
Acceptable Colors by Kennel Clubs
The American Kennel Club (AKC), the official kennel club in the United States, recognizes several coat colors for Australian Shepherds. The acceptable colors include:
- Black: This color can range from solid black to black with white and tan markings.
- Blue Merle: A marbled pattern of gray and black with white and tan markings.
- Red: Ranging from a deep chestnut to copper or light cinnamon color.
It is worth noting that for black or red coats with white and tan markings, acceptability may depend on the size and location of the markings. These acceptable colors are recognized and valued within the Australian Shepherd breed.
Unacceptable Colors and Patterns
Some coat colors and patterns are considered non-standard or undesirable in Australian Shepherds. These colors are not recognized by kennel clubs and are typically the result of specific genetic combinations or mutations. Examples of such colors include:
- Solid Black: Solid black Australian Shepherds are considered rare as the solid black coat color is the result of a recessive gene. Both parents must carry this gene for a solid black puppy to be born, making it less common in the breed (Breed Atlas).
- Yellow: Yellow Australian Shepherds have a light cream coat color and dark noses. They are considered non-standard and are often carriers of a cryptic merle gene. Breeding two merle dogs together is forbidden due to potential health issues, making yellow Aussies non-standard and unrecognized by kennel clubs (Breed Atlas).
- White: White Australian Shepherds have a solid white coat and light blue eyes. They are typically the result of breeding two merle dogs together. However, these dogs are not recognized by kennel clubs and are different from albino Australian Shepherds. White Aussies are known for fragile health and are generally frowned upon by experts.
It’s important to note that while these non-standard colors may still be loved and cherished as pets, they do not conform to the breed standards established by kennel clubs.
Dominance of Coat Colors
The dominance of coat colors in Australian Shepherds is influenced by various genetic factors. These factors determine the inheritance patterns and prevalence of certain colors within the breed. The merle gene, for example, plays a significant role in coat color variations.
Merle is a dominant gene that creates a marbled or dilute pattern in the coat. When a dog inherits a copy of the merle gene from one parent, it will display merle patterning. However, breeding two merle dogs together can result in health issues such as deafness and eye defects in offspring.
While certain coat colors may be more common or preferred within the Australian Shepherd breed, it’s essential to prioritize the overall health, temperament, and well-being of the dog when selecting a pet. The coat color should be just one factor to consider alongside other important aspects such as temperament, size, and grooming requirements.
Genetic Studies on Coat Color
The coat color of Australian Shepherds is influenced by various genetic factors. In recent years, genetic studies have shed light on the loci affecting coat colors, the merle phenotype in dogs, and candidate genes associated with coat color.
Loci Affecting Coat Colors
Coat color in dogs is highly polymorphic, with more than 20 loci identified to affect coat colors. These loci encompass various genes and alleles involved in pigmentation, including the melanocortin 1 receptor gene (MC1R), Agouti, tyrosinase-related protein 1 (TYRP1), and melanophillin. For instance, TYRP1 mutations have been found to be responsible for brown coat color versus black coat color in several dog breeds, including the Australian Shepherd dog (NCBI).
Merle Phenotype in Dogs
The merle phenotype in dogs refers to a coat color pattern characterized by incomplete and irregular dilution of eumelanic regions, resulting in intensely pigmented patches. Dogs with the merle phenotype often exhibit heterochromia iridis (different colored eyes), lack of retinal pigment visible on the fundus, and may have developmental defects like microphthalmia and hearing loss. The merle phenotype is inherited as a dominant trait, and heterozygous dogs typically display this coat color pattern (NCBI).
Further genetic studies have shown that the merle locus in dogs is located at the centromeric end of CFA10 (Canis familiaris chromosome 10), spanning a 5.5 Mb region. This region corresponds to a conserved ordered segment in the human and mouse genome, housing several genes potentially associated with pigmentation and development. The merle locus is linked to the merle coat color with a maximum Lod score of 19.87 (NCBI).
Candidate Genes for Coat Color
Researchers have identified several candidate genes associated with coat color in dogs, including MITF, PAX3, and SOX10. These genes have been found to be associated with coat color phenotypes and developmental defects similar to the merle phenotype in dogs. While the exact mechanism of the merle phenotype is not yet fully understood, studies suggest that it may be influenced by a unique locus called M, potentially involving transposable elements. The Kit Ligand (KITLG) has been excluded as a candidate gene for the merle phenotype in dogs.
Genetic studies continue to contribute to our understanding of the complex mechanisms underlying coat color in Australian Shepherds and other dog breeds. By unraveling the genetic factors at play, researchers aim to further elucidate the inheritance patterns, developmental effects, and pigmentation processes associated with coat colors in dogs.
