Biochemistry of Dog Coat Color. The color of a dogâs coat is determined by relative levels of two pigments: eumelanin, which can be either brown or black, and pheomelanin, which is yellow to orange or red. Both pigments are generated by metabolism of tyrosine. A schematic diagram of the pathway is below. Schematic of the melanin synthesis pathways.
Blue and White. Blue is the colour produced when black is diluted. The dilute gene is also recessive so two copies of the gene must be present in a dogs genetic makeup in order for itâs base colour to be diluted. Both parents must carry the dilution gene in order for it to be produced in a litter.
