Domestic dogs exhibit diverse coat colours and patterns. In many mammals, different colour patterns are the result of the regulation of the Agouti gene, which can cause hair follicles to switch from making black or brown pigments to yellow or nearly white pigments.
Why are dogs multi colored?
Two mutations lead to five phenotypes Wolves and dogs can make two different types of pigments, a black one called eumelanin and a yellow pigment, pheomelanin. The precisely regulated production of these two pigments at the right time and at the right place on the body gives rise to very different coat color patterns.
What is it called when a dog has multiple colors?
Particolor: depending upon the breed, a particolor is a dog that has patches of two or more colors, or that has any color or pattern combined with white. Some particolor patterns include: Piebald (Harlequin, Boston, Pied): mostly white with patches of color usually on the extremities.
