CODE: C128
DNA TEST:
Presence of
black-and-tan and sable colors.
BREED STANDARDS FOR COAT & NOSE COLORS:
The Belgian
Shepherds, which are longhaired, occur in two colors varieties
with separate names. The Tervuren are sable colored dogs
and the Groenendael are black. In addition there are two
other hair coat varieties, both of which are usually sable:
the Malinois is shorthaired and the Laekenois is wirehaired.Tervuren
are typically either ayay or aya.
Therefore if two dogs that are both aya are mated
together, some black pups could occur. Sable in Tervuren
is used to denote a predominance of reddish hairs with occasional
solid black hairs interspered. The number of black hairs
can vary tremendously, probably under the control of another
gene which has not been determined yet. The shade of red
can also vary from cream to deep red. This is under the
control of yet another gene which we are still searching
for. Note that another allele at also occasionally
occurs in Tervuren, and this allele, when homozygous causes
black-and-tan which is a disallowed color in most countries.
DNA testing to detect the presence of the a or at
alleles in dogs that are sable allows breeders to better
predict the colors of pups from particular matings. (note
that Groenendael can be black from the genotype "aa",
which is recessive to sable or from another gene with a
dominant genotype). All Tervuren have a melanistic mask
and are therefore EmEm.
