In dogs, the Liver color is caused by dilution of the eumelanin (black) pigment by the B locus. The gene that causes Liver is recessive, so a BB or Bb dog has normal black pigment. Liver may also be called different names such as Brown, Chocolate, or Red.
Red is a very misleading term, and should be avoided when referring to the color liver because it can be confused for phaeomelanin pigment. This second pigment is what colors all the "true red" or yellow parts of a dog. Liver (S 123) and liver and white (S 125) are very beautiful colors seen with the Shih Tzu breed.
Notable facts and lots of cute photo examples. What Causes Liver Coloring in Dogs? The liver color in dogs is caused by a genetic mutation that dilutes black pigment into a brownish-red shade. All dogs have two primary pigments that make up their coat color: eumelanin and phaeomelanin.
Eumelanin produces black and brown tones, while phaeomelanin produces red and yellow tones. Dog Color Genotypes: Merle, Locus, Liver, Fawn, Fallow, Brindle Albinism in Dogs. Extraordinary, Exotic Color Patterns of Dogs.
The Liver and White Shih Tzu is a unique and charming breed that has captured the hearts of many dog owners. They are a variation of the Shih Tzu breed, known for their distinctive liver. The Liver Gene The liver gene occurs on the B locus, and causes a brownish colour.
It's recessive, so b is liver and B is non-liver, and in order for a dog to be liver it must have the genotype bb. This means that a liver puppy can be born from black parents if both are carriers of the liver allele (i.e. if both are Bb then at least one pup in four will be bb - see the Breeding page).

How do canines display so many coat colors with two primary pigments? Each pigment has a default color that is changed by different genes. Black is eumelanin's default pigment, but genes can modify the color to produce blue (gray), Isabella (pale brown), and liver (brown). Pheomelanin is a red pigment with yellow or gold as the default color.
Liver is a rich, deep reddish-brown color, often seen in various dog breeds. While "liver" isn't a breed itself, it describes a specific coat color caused by a recessive gene. This article dives into the genetics behind the liver coloration, the breeds that commonly exhibit this beautiful hue, and important health considerations for liver.
