Blue and Tan French Bulldog
Dilute blue base with rich tan point markings. Learn the d/d + at/at genotype that produces this stunning combination.
What Makes a Blue and Tan Frenchie Special
The Blue and Tan French Bulldog combines two recessive genes into one visually striking package. The d/d genotype at the D-locus dilutes the black base pigment to a soft blue-gray, while the at/at (or at/a) genotype at the A-locus produces the warm tan points on the eyebrows, muzzle, cheeks, chest, and legs.
The contrast between the cool blue-gray body and the warm tan accents creates one of the most sought-after color patterns in the Frenchie world. The tan points must be clearly defined — muddy or patchy tan distribution reduces visual appeal and value.
Breeders targeting this combo need to verify both the D-locus and A-locus through DNA testing before pairing. A dog that appears blue but tests D/d or D/D cannot produce blue offspring, and a dog without the at allele will never produce tan points.
The Blue and Tan Genotype
D-Locus: Dilute
Required: d/d
Two copies of the dilute allele (d/d) are required to produce the blue base coat. This locus dilutes eumelanin (black pigment) to a blue-gray shade. Without d/d, the dog will be black, not blue.
A-Locus: Tan Points
Required: at/at or at/a
The tan point allele (at) must be present to produce the warm markings on eyebrows, cheeks, chest, and legs. at/at produces more consistent tan points than at/a, where tan expression may be reduced or patchy.
Breeding Blue and Tan: Expected Outcomes
| Sire Dam Pairing | D-Locus | A-Locus | Blue and Tan % | Other Outcomes |
|---|---|---|---|---|
| d/d at/at x d/d at/at | 100% d/d | 100% at/at | 100% | None |
| d/d at/at x d/d at/a | 100% d/d | 50% at/at, 50% at/a | 100% blue | Some with reduced tan |
| d/d at/at x D/d at/at | 50% d/d, 50% D/d | 100% at/at | 50% blue + tan | 50% black + tan |
| D/d at/at x D/d at/at | 25% d/d, 75% other | 100% at/at | 25% blue + tan | 75% black + tan or no tan |
| d/d at/a x d/d at/a | 100% d/d | 25% at/at, 50% at/a, 25% a/a | 75% have some tan | 25% plain blue (no tan) |

Blue and Tan Frenchie FAQ
What is a Blue and Tan French Bulldog?
A Blue and Tan French Bulldog has a blue (dilute gray) base coat with rich tan points on the eyebrows, cheeks, chest, and legs. The tan points come from the A-locus (at/at or at/a) and only appear when the dog also carries a copy of the tan point allele.
What is the genotype of a Blue and Tan Frenchie?
The genotype is d/d for dilute (blue) combined with at/at or at/a for tan points. The dog must be homozygous or heterozygous at the A-locus for tan points AND homozygous recessive at the D-locus. Without at/at or at/a, the tan markings won't express.
Can two Blue and Tan parents produce Blue and Tan puppies?
Yes, but not guaranteed. Both parents must pass the d allele and the at allele. If one parent is D/D (no dilute), no blue puppies will result. If one parent is a/a (no tan point), no tan markings will appear on the puppies.
How much does a Blue and Tan Frenchie cost?
Pet quality Blue and Tan French Bulldogs typically range from $4,000 to $7,000. Premium specimens with perfect tan point distribution and clean conformation can reach $8,000–$12,000. The price reflects the dual recessive requirement.
Is Blue and Tan the same as Blue Fawn?
No. Blue and Tan has distinct tan point markings (eyebrows, cheeks, chest, legs) on a blue base. Blue Fawn has a fawn/tan coloration over the entire body with a blue mask and blue shading, without the sharp tan point contrast. They are genetically different combinations.
Are Blue and Tan Frenchies recognized by the AKC?
The standard French Bulldog color palette does not include blue or tan points. While these dogs can be AKC-registered, they are not eligible for conformation shows under the current breed standard. Many breeders focus on pet and breeding markets instead.
