| This chart covers the 4
rare Colors being produced in Purebred AKC
Bulldogs aka "English Bulldogs", which are
LILAC, BLUE, CHOCOLATE, and BLACK. AKC Color
codes are provided for each color desigantion.
We are hoping that more breeders & pet owners
will CORRECTLY register their babies color with
the codes provided here. You can see the color
codes given by AKC for Bulldogs
HERE. ALL English Bulldog Breeders of
AKC Rare Colors should use the same Color Codes
for registering their dogs, so as to preserve
the stability of the Rare Color Lines and for
Breeders to accurately plan their breeding
program for the Rare Colors. This is a GOOD
chart, as I have conferred extensively with AKC
as to what the descriptive color of their codes
are, and therefore the codes chosen are as close
as you can possibly get to the true color of
each dog. Note: Fawn Markings (008) indicate the
Tan Pointed Pattern on ANY color dog. |

NEW DNA INFO ON THE LILAC COLORS |
From the scientists at UC Davis and Vet Gen.
Both scientists said the exact same thing about
the difference between a True Color Lilac and a
Lilac fawn/Lilac Brindle.
You can dna at the K locus to find out if your
lilac is a fawn(red coat base) or a true
color(black base coat).
At UC Davis, results will show KK or KN to be a true
color lilac(it takes only one side of a Dominant
Gene for the color to present on the dog), NN
would be a lilac fawn. NN would mean the lilac
fawn does not carry the Dominant Black Gene
which is the most common of black genes in EB's,
and cannot throw Black, True Blue, True Color
Lilac, or Dark Chocolate at the K loci, but can
produce at the agouti & at the recessive black gene, IF it is a
carrier at those alleles, AND only if the mate carries
the same. Bottom line, the Lilac
Fawn does not Guarantee to throw all 4 Rare
Colors to it's offspring.
At Vet Gen, the results are a little different.
Not the genetics themselves, but merely the way
they choose to interpret it to their customers.
Results will show KBKB, or KYKB to be a true color lilac,
KYKY would be a lilac fawn. KYKY would mean the
lilac fawn does not carry the Dominant Black
Gene, and cannot produce black puppies at the K
loci as explained above. |

needed to lighten black pigment to grey (often
called blue) and red pigment to cream (often
called blue fawn). |

As if this were not confusing
enough, I have now been advised that there are 3
Sequences to the b genotype. Which means you can have
either b, b2, or b3 on your dogs DNA. This can be on one
or both sides of the complete gene. Therefore, it is
possible to have your dog dna any one of the following
types:
Bb Bb2 Bb3
bb bb2 bb3
b2b b2b2 b2b3
b3b b3b2 b3b3
Some labs recognize all 3 sequences and some don't, so
you could have a b2 or b3 on your dog and not know it.
What does this mean? To put it simply, the more little
b's your dog has, the higher the percentage SHOULD be as
to the puppies your dog will give it to. |

Chocolate Buff
Chocolate Fawn & White, but much lighter The
dilution gene on red dogs does not change the
hair color, which is why these dogs will look
standard color but actually be chocolate. The
nose, eyeliner, and pads should be light to dark
chocolate as in the True Chocolate Colors. The
eyes are often light gold, green, grey, or blue.
