French Bulldogs are one of the most popular dog breeds in the world, known for their small size and affectionate personalities. They come in a variety of colors, which can be attributed to their genetic makeup. In recent years, DNA testing has become increasingly popular among French Bulldog breeders and owners to determine their dog’s color genetics. In this article, we will be discussing the French Bulldog DNA colour chart and how it works.
What is a French Bulldog DNA colour chart?
A French Bulldog DNA color chart is a tool that can be used to determine the possible color outcomes of a French Bulldog puppy based on its parents’ genetic makeup. It works by analyzing the DNA of the parents and predicting the likelihood of certain coat colors appearing in their offspring.
The Basics of Coat Colour Genetics
The colour of a dog’s coat is determined by a combination of genes, including those responsible for pigmentation and pattern. Each gene has two variants, or alleles, one inherited from each parent. In some cases, these alleles are dominant or recessive, meaning that one or the other will determine the dog’s coat colour. In other cases, both alleles may contribute to the final colour in a more complex way.
Understanding French Bulldog Genetics
French Bulldogs can come in a variety of coat colours, including fawn, brindle, cream, pied, and black. However, there are also variations within each colour category that can make it difficult to determine a dog’s exact colour without genetic testing.
To understand the genetics behind French Bulldog colors, it’s important to know that each dog has two copies of every gene – one inherited from their mother and one from their father. Some genes have dominant and recessive traits, meaning that one gene can override the other.
When it comes to French Bulldog colors, there are three main genes that play a role: the B locus, the D locus, and the E locus.
The B Locus
The B locus determines whether a French Bulldog will have a black or chocolate coat color. The dominant B allele results in a black coat, while the recessive b allele results in a chocolate coat.
The D Locus
The D locus is responsible for determining whether a French Bulldog will have a diluted coat color, such as blue or fawn. The dominant D allele results in a full color coat, while the recessive d allele results in a diluted coat color.
The E Locus:
The E locus determines whether a dog will have black or yellow/red pigmentation in its coat. There are three known alleles for this locus: E (dominant, allows for black pigment), e (recessive, allows for yellow/red pigment), and EM (dominant modifier, can lighten or dilute black pigment). French Bulldogs with two copies of the recessive e allele will have a yellow or red coat, while those with one or two copies of the dominant E allele will have a black coat. Those with one copy of E and one copy of EM may have a diluted black coat, known as blue.
The K Locus:
The K locus determines whether a dog will have a solid coat colour or a patterned coat. There are two known alleles for this locus: K (dominant, allows for solid coat colour) and kbr (recessive, allows for brindle pattern). French Bulldogs with two copies of the recessive kbr allele will have a brindle coat, while those with one or two copies of the dominant K allele will have a solid coat.
The D Locus:
The D locus determines whether a dog’s coat colour will be diluted. There are two known alleles for this locus: D (dominant, no dilution) and d (recessive, dilution). French Bulldogs with two copies of the recessive d allele will have a diluted coat colour, known as fawn or cream. Those with one copy of D and one copy of d may have a diluted black coat, known as blue.
The S Locus:
The S locus determines whether a dog will have white markings on its coat. There are two known alleles for this locus: S (dominant, allows for white markings) and sp (recessive, no white markings). French Bulldogs with two copies of the recessive sp allele will have no white markings, while those with one or two copies of the dominant S allele may have white markings in various patterns.

Now that we have a basic understanding of French Bulldog genetics, let’s dive into the different coat colors that can occur.
Black
A black coat is the most common color in French Bulldogs. A dog with two dominant B alleles (BB) will always have a black coat. However, a dog with one dominant B allele and one recessive b allele (Bb) will also have a black coat.
Chocolate
A chocolate coat is less common in French Bulldogs, but still possible. A dog with two recessive b alleles (bb) will have a chocolate coat.
Blue
A blue coat is a diluted black color, and is caused by the recessive d allele at the D locus. A dog with two recessive d alleles (dd) will have a blue coat.
Fawn
A fawn coat is a diluted red color, and is also caused by the recessive d allele at the D locus. A dog with two dominant D alleles (DD) will have a full color coat, while a dog with one dominant D allele and one recessive d allele (Dd) will have a fawn coat.
Cream
A cream coat is a variation of the fawn color, and is caused by the recessive e allele at the E locus. A dog with two recessive e alleles (ee) will have a cream coat.
Brindle
A brindle coat is a mix of black or chocolate with another color, such as fawn or cream. Brindle patterns can vary greatly, but are caused by the interaction between the B and K loci.
Pied
A pied coat is a coat with white spotting, and is caused by the recessive e allele at the E locus. A dog with two recessive e alleles (ee) will have a pied coat.

Now that we’ve discussed the different genes responsible for coat colors in French Bulldogs, let’s take a look at the French Bulldog DNA color chart. This chart shows the possible coat colors and patterns that can occur in French Bulldogs based on their genotype at each of the four relevant genes (B, D, E, and K).
Possible Coat Colors and Patterns in French Bulldogs
- Black (BB or Bb, dd, EE or Ee, kk or Kk)
- Fawn (BB or Bb, dd, EE or Ee, kk or Kk)
- Brindle (BB or Bb, dd, EE or Ee, kk or Kk, plus additional brindle gene)
- Cream (BB or Bb, dd, ee, kk or Kk)
- Blue (BB or Bb, dd, EE or Ee, kk or Kk)
- Chocolate (bb, dd, EE or Ee, kk or Kk)
- Lilac (bb, dd, EE or Ee, kk or Kk)
- Isabella (bb, dd, EE or Ee, kk or Kk)
Understanding the French Bulldog DNA color chart can help breeders and pet owners predict the coat colors and patterns of their French Bulldogs. Keep in mind that other genes not discussed in this article can also play a role in coat color, and that coat colors and patterns can vary widely within a litter of puppies. Ultimately, what matters most is the health and happiness of your French Bulldog,
How does the French Bulldog DNA colour chart work?
The French Bulldog DNA color chart works by analyzing the specific genes that control coat color in French Bulldogs. There are several genes that are responsible for coat color, including the A locus, which controls the production of melanin, and the D locus, which determines if a dog will have a diluted coat color.
Based on the DNA analysis of the parents, the French Bulldog DNA color chart can predict the possible color outcomes of their offspring. For example, if both parents have the dominant A allele, their offspring will likely have a black or brindle coat. If one parent has the dominant A allele and the other has the recessive a allele, their offspring could have a black, brindle, or fawn coat.
