Coat Colors In Cockers

Of Heredity #29
This is only the cocker spaniel
part of the article as other breeds mentioned is not of importance to this
Orthodox coat colors in Cockers
do not include brindle or sable, or any of the agouti or chinchilla types
of color, the Standard recognizing only self black, self liver, any shade
of self red or yellow, black and tan and liver and tan, and any of these
colors with the recessive piebald white splashing.
The Cocker bitch under consideration
was bred by Mr. Landaker of Cincinnati, Ohio, and is owned by Mrs. Walter
Elliott of Duncan Falls, Ohio. She is dark red with many black hairs
distributed rather evenly through the coat, mostly on the dorsal surfaces.
They are most numerous on the face and around the edges of the ears. None
of the hairs is banded but each is jet black throughout its entire length.
The eyes and nose are black. There were several red litter mates,
but she was the only one to show this pattern. The black hairs were
not arranged in bands but were scattered uniformly though the coat when
she was whelped and her puppy coat was short. None of her ancestors
was sable or brindle, and for several generations none had ever been know
to throw sable. Mated to a black dog, heterozygous for the black
and tan bicolor pattern, and which also carries buff as a recessive, she
threw one black and three reds varying from medium to dark red and one
rather light red with very heavy sabling, which in addition to the sable
pattern shows areas of clear buff which correspond exactly to the position
of the tan areas in a "bicolor black and tan." The black hair in
this dog also is much longer than the buff. Another mating to a solid
homozygous black threw only black as one would expect, but contrary to
expectations a third mating with a dark red with black nose threw four
red pups, one dark and three medium but no sables. The black which
threw the sable was a total out cross and had never been know to throw
a sable, nor had any of his ancestors.
It would therefore appear
that this color, though phenotypically resembling the sable of Collies
is genotypically quite different, and even though the black does not occur
in streaks but is uniformly mixed with the red on the bodies of the dogs,
it is much more closely related to the sable of St. Bernards and the brindle
of Great Danes, Greyhounds, etc. which are recessive to self black
but dominant over red, fawn, tan, etc.
I have heard of two other
Cockers of this color whose description tallies exactly. Both of
these were the product of red by black mating, and came from stock which
had never thrown brindle or sable. This sable coloring is quite common
in certain strains of Springer Spaniels, in which breed it appears as sable
patches on piebald dogs and from the figures which I have been able to
obtain it seems to be recessive to black and dominant over red and yellow.
In Springers red and white and sable and white are unpopular colors consequently
most of them are destroyed at birth, but they keep recurring from the black
and white stock.
Whether these examples cited
in Cockers are the result of recessive "throwbacks" or arose from three
individual mutations it is impossible to say, but they were found in three
very remotely related strains of the breed.
