French Bulldog Coat Color Calculator
Enter the DNA of the sire and the dam and instantly see the litter’s color, pattern and carrier probabilities, with an illustration of every possible puppy.
Possible puppies
Expected carriers
Probabilities per puppy based on the DNA entered; they don't guarantee the outcome of a litter. Big Rope, structure and other traits don't depend on a single gene and aren't calculated here. Illustrations are for guidance only.
With one copy of Pied (N/S) the illustration shows a white chest marking as a representative phenotype; in reality, a single copy does not always produce it.
Request a breeding evaluationHow to use the calculator
- Choose Sire or Dam and set both copies of each gene: the left row is one copy and the right row the other.
- If you don’t know the full DNA, start with Valentino or Zeus, our studs, and change only what you know about your dog.
- Tap Breed: you’ll see every possible phenotype with its per-puppy percentage, its illustration and the expected carriers.
Genes and traits included
- Agouti
At · Ay · aFawn (Ay), tan points (at) or recessive black (a). - Dilute
D · dWith two copies of d, dark pigment is diluted to blue. - Cocoa
Co · coTwo copies of co produce cocoa. - Testable Chocolate
B · bTwo copies of b produce Rojo (testable chocolate). - Dominant Black
Kbr · KyKbr adds brindle; Ky lets the Agouti pattern show. - Cream
E · e · EmTwo copies of e give cream or platinum; Em adds a mask. - Pied

L · lWith two long-coat copies the puppy is fluffy. - Intensity

N · LAARecessive: two copies express it; one copy carries it.
Before you read the results
Percentages are per-puppy probabilities based on the DNA entered, not a guarantee of what a litter will contain. Illustrations are indicative. We do not breed merle × merle in our program.
