This chart covers the 4 Rare Colors & several Patterns, being produced in Purebred AKC Bulldogs aka "English Bulldogs", which are LILAC, BLUE, CHOCOLATE, both kinds of BLACK, plus the MERLE Pattern. 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.

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.

It is important to realize that the genetics of coat color is very complex and confusing. Research is ongoing, so what we know today can very well be proved untrue, may change, or be added to in the future. That being said, this Chart, like the Genetic Lab sites, will need to change/update information as it comes to light.
 
Note: Fawn Markings (008) indicate the Tan Pointed Pattern on ANY color dog.
 
The photos on this chart are from Rare Bulldogs unless otherwise noted.
~~~IMPORTANT~~~
Breeders, please put your dogs color somewhere in the AKC Registered name so as to preserve Rare Color Pedigrees.
For example, we have been using our catch phrases now for years:
"Blu Dreams", "Chocolate Sensations", "Lilac Passions", "Black Beauty", "Platinum Perfection", & "Marvelous Merles".
You could also just put the color in parenthesis at the end of the name like this: (Lilac)
 
RARE COLOR SECTION 1: LILAC ENGLISH BULLDOGS
Genotype for Lilac Gene: [bb dd]
(this is a combo gene, full blue & full chocolate combined)
 
Overview: Lilac Bulldogs start out black, then diluted not once, but twice, by the Chocolate Gene, then the blue gene. The [bb] dilutes black to brown, and the [dd] dilutes the black to blue. Try mixing blue & brown paint, you will get soe shade of purple or lilac. The lilac coat should be shiny and looks very close to Weimerainer Grey, with many lighter & darker shades possible. Some lilac coats will have an under color shine through that can be green or pink or somewhere in between according to the light the dog is in. The nose, eyeliner, and footpads are also always some shade of purple/lilac.

RARE COLOR SECTION 2: BLUE ENGLISH BULLDOGS
Genotype for Blue Gene: [dd]
 
Overview: Blue Bulldogs are diluted black dogs. The blue/grey coat should be shiny & look grey against black objects or in the sun unless it carries the Seal gene, which would show maroon or other color undertones. These dogs may or may not have a fawn undercoat when the hair is rubbed backwards. The nose, footpads, & eyeliner are always blue/grey, which can vary from light to dark, not to be mistaken for black.

Note: it is unfortunate that we have to register our blue dogs with the same AKC color codes as the Lilac. Therefore it is extremely important for Breeders & Puppy Parents to use the descriptive terms in their dogs names as described in the "IMPORTANT" SECTION above.

RARE COLOR SECTION 3: CHOCOLATE ENGLISH BULLDOGS
Genotype for Chocolate Gene: [bb]
 
Overview: Chocolate Bulldogs are diluted black dogs from a different dilution gene than the blue. The chocolate coat should be shiny and look brown against black objects or in the sun, unless the seal gene is involved which can give different undertones to the coat. These dogs may or may not have a fawn undercoat when the hair is rubbed backwards. The nose, footpads, & eyeliner are always chocolate, even in the chocolate fawn.

INFORMATION SECTION
More info on:
TAN POINTS, PLATINUM, FAWN VS. TRUE, BRINDLE & TRINDLE, SEAL, MERLE
 
INFORMATION SECTION 1: TAN POINTS
As in all the Tri Colors (3 colors on the dog one of which is always the tan points), the tan points are typically on the eyebrows, cheeks, front shoulders (right above the chest area between the legs), around the tail, and partial on both front & back legs. Tan points will not show up if the dog is white where the points would normally be. Tan points can also be hidden by other genes, such as the SEAL gene, as it is higher on the heirarchy. Tan points can bleed through on some dogs when only one [at] is present. It normally takes a double [atat] dog to show tan points. As of this writing, the geneticists do not know why this happens on some dogs with the same dna & not others.
INFORMATION SECTION 2: PLATINUM
 
Platinum basically means an ALL WHITE Dog. Platinum is not a color, but is rather a lack of pigment. So you can technically have a genetic true color dog, such as a Dark Chocolate Tri who is ALL white! It has been accepted for over 5 years now, that dogs with spots of color that represent 10% or less of the total body color, mmay be designated Platinum. The preferred True Platinum has an all white coat.
 
INFORMATION SECTION 3: FAWN VS TRUE COLORS
 
In Red/Yellow (Fawn) dogs, the hair is not affected by the 2 DILUTE genes [bb & dd]. The nose, footpads, & eyeliner is the only thing affected byt these color genes. Therefore, you can have a dog with it's original hair color, but with diluted pigment as noted. These dogs are correctly referred to Lilac Fawn, Blue Fawn, & Chocolate Fawn. There is no Black Fawn, this is the same as the standard fawn dog with a black nose.

For any color dog to be TRUE color rather than Fawn Color, it has to have a FULL Black Base. The 2 black Bases are the SEAL gene [Kb], and the Black & Tan gene [atat].
INFORMATION SECTION 4: BRINDLE & TRINDLE
 
The genes that cause dogs to be Brindle are not yet fully understood, even by the scientists themselves. What we do know so far is that one of the markers on the K gene, specifically Kbr, is responsible for the brindle color on the coat, whether it be a partial or full brindleing, such as the Tan Points being brindled, which is what we call Trindle or Clear. The agouti gene overides the brindle gene on the dogs body coat & makes it look solid color, except for any area where the dog is tan pointed.

The K gene is incorrectly called Dominant Black, because this gene can produce brindle, & black (seal). ALL brindle dogs carry at least one K gene. Yes, it takes only one since it is a Dominant gene to show on the dog. The Merle gene is the same.
INFORMATION SECTION 5: SEAL
 
The genes that cause dogs to be SEAL (black) are not yet fully understood, even by the scientists themselves. What we do know so far is that one of the markers on the K gene, specifically Kb, is responsible for the solid black color on the coat, which also covers any tan points on the dog. In connection with the other color genes, you can get Black Seal, Lilac Seal, Blue Seal, & Chocolate Seal. These dogs usually have another undertone color shining through the true color, which could confuse some in determing true color by site only. The seal gene tends to have a muddy affect on the color, but yet not taking out the shine to the coat.
INFORMATION SECTION 6: MERLE
 
The Merle Gene dilutes random sections of hair to a lighter color which leaves Patches of the original color, sometimes these patches can be very small. If you start with a black dog and add the Merle Gene, you still have a black dog genetically, but with sections of the black diluted. Unlike the piebald pattern, these patches or sections may look jagged on the outer edges. Merle affects only the Eumelanin, and does not affect the Phaeomelanin (red/fawn) which will appear normal. This means you can have a merle dog & not see it visually. Merle affects only black based coat color. Eyes, and noses can also be merled.

Black Merle dogs are often called Blue Merle because the Merle gene dilutes patches of black to a grey color. Blue Merle on genetically Black Merle dogs is a widely used term, but is not correct. They should be called Black Merle, their nose, footpad, & eyeliner pigment is still black. If these dogs did not have the merle gene, they would be solid black. The term Blue merle, when used on black dogs is misleading because blue dogs should have the [dd] gene if they were truly blue. A black merle dog will never have the double [dd] gene, but the True Blue Merle dog would always be [dd]. It is the patches on the dog that will visually define the dogs color and what it should be appropriately called. This can be backed up with DNA testing. Thus in the True Blue Merle dog, the patches that are left would be True Blue and the sections that are diluted would be a much lighter color blue. This is the case in all the Rare Colors. The sections left on the lilac Merle dog are almost white, it is so light. Makes since when you think about it. There are 3 dilution genes at work in a Lilac Merle dog. Some of these colors will blend in with the diluted color so much, that DNA Color Testing may need to be done to be sure of the true color.

The Merle gene when doubled up, can cause health issues, mostly deafness & blindness. For this reason, two merles should never be bred together, as this could result in double Merle puppies with problems. These problems are virtually eliminated in single Merle gene dogs. Double Merle can be problematic because it can cause lack of pigment in certain vital areas, such as the eyes & inner ears. Single merle dogs have plenty of pigment because they still have a non-merle allel to make pigment. Double Merles often have large areas of white where there is no pigment produced.

In the heirarchy of genes, the Merle Gene overrides the Dominant Black(SEAL) gene, the Seal gene overides the black & tan gene, so you can have a Black & Tan, Black Seal, Black Merle dog and would mainly see only the merle. It is very important to know the TRUE DNA of your dog if you plan to breed.
