![]() ![]() ![]() The spotting gene will show it’s white markings also on dominant black coat.īrown (Liver/chocolate): Only if a dog is homozygous for brown (b/b) black pigment will be diluted to brown. If a dogs genotype contains at least one copy of Kb, the dog will express its basic coat colour, according to the B-, D- and E- locus alleles. The K-locus is known for dominant black coat colour and will suppress the a-locus in showing its phenotypically traits. Within the A-Locus ranking, Ay is the most dominant as you can see below:Ī y Fawn ⇒ a w – Agouti/Sable ⇒ a t – Tan ⇒ a – Recessive blackĪ solid black dog is either recessive black (a/a) or dominant black (Kb), additionally B-, D- (no dilute) and E/E (no recessive red). Recessive black is a rare trait, but common in GSDs. Phenotypically a recessive black dog shows no difference to a dominant black coated dog. In combination with the tan allele at the dog will be bicolor. Recessive black: In homozygous form ( a/a), the a- locus results in black coat colour (in case of dilution blue, brown or lilac). Otherwise the dog shows an eumelanin (black pigment) coat (in case of dilution eumelanin will appear blue, brown or lilac) The typical tan pattern shows red spots and patches on the muzzle, above the eyes and on feet, tail, ears and chest. Tanpoint: The third option contains black and red pigment in a specific pattern ( a t). Dark types of sable shepherds are called often Melanistic Sable or Dark Sable or in contrary to the dark version there is light sable too or faded sable. The shades of agouti can vary widely and may change over years. You can find agouti in other breeds too, like for example the Alaskan Malamute. Sable is actually the wrong term to describe agouti in GSDs, but It’s the most common way. Banded hairs (black and red) create the camouflage effect many wild animals have ( a w). On the dorsal line a fawn dog usually shows black hair tips.Īgouti (Wolfgrey/Sable): This is one of the most recent colours in GSDs next to black and tan. It’s actually a rare colour within the German shepherd lines. Dominant Fawn (True Sable): The dominant A y gene typically creates a sandy coat colour, most likely in combination with a black mask, which you can find in Malinois dogs for example. ![]()
