Australian Cattle Dogs, like many pedigree breeds, are predisposed to an eye condition known as progressive retinal atrophy. “This is an inherited problem with no known treatment or cure.
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 ...
Progressive retinal atrophy (PRA) is a group of genetic diseases seen in certain breeds of dogs and, more rarely, cats. Similar to retinitis pigmentosa in humans, [1] it is characterized by the bilateral degeneration of the retina, causing progressive vision loss culminating in blindness.
Brave dogs need love too. Just like an Australian Cattle Dog who turned back into a puppy after a little boo boo on the ranch. The dog sure is tough — but even tough pups need a little love ...

Melanin is the protein that creates skin, eye and hair color. More melanin means darker eyes, hair or skin. The color of the melanin in the eyes is determined by three other genes, EYCL1, 2 and 3 ...
Eye color, specifically the color of the irises, is determined primarily by the concentration and distribution of melanin. Although the processes determining eye color are not fully understood, it is known that inherited eye color is determined by multiple genes. Environmental or acquired factors can alter these inherited traits. [7]
