By 2020, more than eight genes in the canine genome have been verified to determine coat color. [3] Each of these has at least two known alleles. Together these genes account for the variation in coat color seen in dogs. Each gene has a unique, fixed location, known as a locus, within the dog genome.
A dog's coat is composed of two layers: a top coat of stiff guard hairs that help repel water and shield from dirt, and an undercoat of soft down hairs, to serve as insulation.

According to Candille, et al. (2007), dog coat color can largely be explained by three genes: MC1R, Agouti and CBD103. 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 ...
The early history of the Smooth Collie, like that of many dog breeds, is a matter of speculation. Even the origin of the breed's name is unclear, variously claimed to describe the early shepherd dog's dark colour ("coaly") or derived from the name of a breed of sheep with black faces once commonly kept in Scotland ("Colley") or derived from an Anglo-Saxon word meaning "useful."
