Dog Colour Liver
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.
The liver color is the result of a recessive dilution gene that. 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. 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.
Only a bb dog is Liver. There are several different recessive b genes, but they all turn the coat brown. The Liver Gene The liver gene occurs on the B locus, and causes a brownish colour.
Dog Coat Colour Genetics
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).
The. What Makes a Shih Tzu Liver-Colored A liver-colored Shih Tzu is a Shih Tzu with a specific coat color, ranging from light brown to dark chocolate. The term "liver" refers to the color of the dog's nose, lips, and eye rims, which are also a brown or chocolate hue instead of the standard black.

Do Liver Shih Tzus Meet Breed Standards According to the AKC Shih Tzu breed standard, liver. 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. To produce the liver color, the dog should have the combination bb. Since the liver color replaces the black in the GSD's coat, they are often the offspring of solid.

Canine Coat Color Genetics, Part 2 Liver and Blue Coat Colors Fred Lanting, All-Breed Judge, SAAB, Sieger/Schutzhund In Part One, I mentioned that a recently discovered chromosome location called the K locus, which has genetic information on (control over) such coat-color expressions as solid black, brindle, and part of the reason for tan markings. I also mentioned the "agouti" genes found. The color liver (dogs) with hexadecimal color code #b86d29 is a shade of orange.
In the RGB color model #b86d29 is composed of 72.16% red, 42.75% green and 16.08% blue. Revised November 2011 Most black, brown, and yellow colorations are due to the presence of melanin class pigments. The word melanin is derived from the Greek word for black, and is commonly used to refer to the two or three known chemicals similar to each other, which produce the above color families.
It can be said that there are only two colors in the haircoat of the canine: black and yellow.
