Aussies can have brown, blue or amber eyes, and sometimes a combination of colors! This is a high-energy herding breed known for having stunning blue merle or red merle coats.
The second way blue eyes can appear is when a dog has a lot of white fur on the face. Since the white areas cannot produce any pigment, pigment from the eyes and nose may be lost as well. [68] The third way is when dogs are affected by albinism. [68] A different gene, unaffected by coat color, can make the eyes blue. However, this gene is rare.
Blue merle Border Collie puppy Red merle Australian Shepherd. Merle is a genetic pattern in a dog's coat and alleles of the PMEL gene. It results in different colors and patterns and can affect any coats. The allele creates mottled patches of color in a solid or piebald coat, blue or odd-colored eyes, and can affect skin pigment as well. Two ...
Tricolor: Three clearly defined colors, usually either black, liver, or blue on the dog's upper parts, white underneath, with a tan border between and tan highlights; for example, the Smooth Collie, the Rough Collie, the Papillon, or the Sheltie. Tricolor can also refer to a dog whose coat is patched, usually two colors (such as black and tan ...
Blue: A dark metallic gray, otherwise known as slate; diluted black pigment. Blue merle is genetically black, not blue. [3] Sable: Black-tipped hairs; the background color can be gold, silver, gray, or tan. White: Distinct from albino dogs. Buff: Such as the buff Cocker spaniel. All these colors can also be dilute, meaning they become a paler ...
The D locus dilutes black pigment to a blue-grey color usually called Blue. It is a recessive trait like Liver. When a dog has both Liver and Blue dilution, it will appear to be a light, warm-gray color known as Isabella. This is the color of Weimaraners. This color also has alternate names such as Liliac or Silver.
The coat may be mouse-grey, roe-grey or silver-grey in various shades, or of a colour intermediate between these; minor white markings to the feet and chest are tolerated. [1] The eyes are amber, ranging from pale to dark; the ears are pendent, with rounded tips. [1]
When a dog has wild-type alleles at all three genes, it will have a yellow coat. When the dog has a loss-of-function allele at MC1R, it will have a yellow coat regardless of the genes it carries on the other two genes. Only a dominant black allele at CBD103 will produce a black coat color in dogs possessing wild-type alleles at MC1R and Agouti. [8]
