CODE: C128
DNA TEST:
Presence of bicolor, solid black and sable colors.
BREED STANDARDS FOR COAT & NOSE COLORS:
There are several "a" alleles at the agouti locus in German Shepherd Dogs (GSD) and these account for virtually all
of the coat color variation in this breed. Sable in GSD is used to denote hairs that are banded with black tips and base
and reddish or cream in between. This is a different use of sable than in many other breeds that use sable to mean a
predominance of reddish hairs with occasional solid black hairs interspersed. Sable in GSD is thought to be caused by the
aw or wild type allele. Some GSD are also black-and-tan or saddle-tan. This coat color is caused by either an at
at or ata genotype. Finally some GSD are solid black. Such dogs have the genotype aa.
DNA testing to
detect the presence of the "a" allele in GSD that are sable or black-and-tan allows breeders to better predict the colors
of pups from particular matings. Although most GSD have a melanistic mask, a few do not. Both the Em and E alleles are
present in German Shepherd Dogs and therefore the E genotype will also be reported. The "e" allele should not be present
in traditionally marked GSD, but has been observed in some dogs reported as white GSD. The German Shepherd Dog varies in
color and most colors are permissible. Strong rich colors are preferred. Pale, washed-out colors and blues or livers are
serious faults. A white dog must be disqualified.
