Color(s):
Solid black, yellow, or chocolate
Are there golden Labs? What is the difference between golden and
yellow Labs?
Labradors come in three colors: black, chocolate, and yellow.
Yellow Labradors are often mistakenly called "golden Labradors."
The term yellow refers to a range of color from nearly white to
gold to fox-red. The Golden Retriever is a separate breed from the
Labrador, although there are similarities. Sometimes the term is
used informally to refer to a Labrador / Golden Retriever mix.
Are there any other colors of Labradors?
No. Black, chocolate, and yellow are the only correct colors. While
mis-marked purebred Labradors are possible, be wary of those
selling "rare" Labradors of other colors at exorbitant prices.
There are yellow Labradors that are so pale they appear white, but
they are still considered to be yellow and will usually have some
color, even if it is only on the ear tips. These lighter yellows
not unusual nor rare and should not command a significant price
hike. The same goes for "fox red" Labradors. Variations in the
color of yellow Labradors are not penalized, but treated the same
as any other yellow Labrador; however the lighter shades tend to
predominate in the ring at this time.
"Silver" Labradors are purely a scam and are either crosses with
Weimaraners or very light chocolates. An actual silver Labrador
(possibly a dilute chocolate) would be treated as a mismarked dog
and not command a high price. To our knowledge, "blue" Labradors
(dilute blacks) have never been offered, but if they were, the same
caveats as the silver Labs would apply. It's possible the silver
Labs are actually dilute blacks; no one has done any test breeding
to verify and the owners of the silver kennels are remarkably
secretive about their dogs. However, based on a comparison with
Doberman Pinschers, it seems reasonable to speculate that silvers
are dilute chocolates ("fawns" in Dobermans).
Can you get yellow Labradors from black ones? And vice versa? What
about chocolates?
Yes, you can get yellows from blacks and blacks from yellows.
Similarly, you can get chocolates from blacks or yellows and
vice-versa. It all depends on what color genes the parents carry.
The only absolutes are that if both parents are yellow, the
resulting puppies are always yellow, never black or chocolate; if
both parents are chocolate, you can get yellow or chocolate puppies
but never black ones.
Are there differences between Labs of different colors?
Aside from the color itself, there are no differences. Many people
feel that black Labs are better hunters, yellow dogs are lazier,
and chocolate dogs are hardheaded and stubborn. None of this is
true. The reason is pure genetics. Coat color in normally colored
Labs is determined by two genes unrelated to anything else about
the dog. It is perfectly possible to get all three colors in the
same litter, therefore the notion that there is a color based
difference in temperament and/or ability is absurd.
Alright, so what is the nitty gritty on coat color inheritance?
Two sets of genes, not one, control a Lab's coloration. One set of
genes controls whether the Lab will be dark (either black or
chocolate) or light (yellow). Dark is dominant over light. Thus a
Lab whose genotype is EE (homozygous dominant) or Ee (heterozygous)
will be dark; only Labs that are ee (homozygous recessive) can be
light.
The second set of genes only come into play if the Lab is dark
(either EE or Ee). This set controls whether the Lab is black (the
dominant trait) or chocolate (the recessive trait). Thus, a dark
dog (ie. EE/Ee) that is BB (homozygous dominant) or Bb
(heterozygous) will be black, while the only way a dog can be
chocolate is for it to be dark (EE/Ee) AND bb (homozygous
recessive).
So now, the possibilities for black dogs are EEBB, EEBb, EeBB, or
EeBb. The possibilities for a yellow dog are eeBB, eeBb, or eebb.
And the possibilities for a chocolate dog are EEbb or Eebb.
Remember that puppies will get one E/e from the dam and one from
the sire, as well as one B/b from the dam and one from the sire to
make up their complete "code". If you had two parents that were
both EeBb (black in appearance), you can get all three colors in
the resulting litter! Furthermore, when you realize that a pair of
yellows can only give their puppies the ee combination, you
understand why two yellows only produce yellows. In a similar
fashion, two chocolates can only bequeath bb to their puppies, so
two chocolates can never produce a black puppy.
The eebb is an interesting case, as this is a yellow dog with
chocolate pigmentation on its nose and eyerims. A dog that is bb
always has this pigmentation. Under the current standard, a yellow
with chocolate pigmentation is disqualified.
If the Lab is mismarked, for example Black and Tan, or brindled,
there are other allelles present in that dog's makeup. If you are
interested in a further discussion of these genes, do look up
Clarence C. Little's classic book, The Inheritance of Coat Color in
Dogs.
Traditionally, the way to determine a dog's genetic background for
color is to examine the whelping box: a dog that produces yellows
and/or chocolate carries those genes. And dogs carry what their
parents have; a black with one yellow or chocolate parent must
carry the yellow or chocolate gene. But for those who really want
to know for certain can now make use of a simple cheek swab test to
determine their dog's genotype. VetGen (1-800-483-8436) has such a
test for $85.
What is a Dudley?
This is a yellow Labrador with chocolate pigmentation (eebb). It
can also refer to a Lab with absolutely no pigmentation on the nose
or eyerims (all pink in color), but in actuality, this is extremely
rare, and probably a genetic abnormality. Please be aware that,
while this trait is considered undesirable, it does not indicate
some sort of genetic abnormality. There is no known correlation
between Dudley noses and poor health.
