Blue and tan is exactly what the name describes: the classic tan point pattern — markings above the eyes, on the cheeks, chest and lower legs — laid over a diluted base, so what would be black reads as slate grey.
The genetics
Two separate recessives have to line up. The dog needs at/at at the A locus for tan points, with ky/ky at K so brindle does not overlay it, and d/d at the D locus for dilution. Both parents must carry both.
That is the whole reason for the price. Neither gene is rare in isolation; producing them together reliably requires selecting breeding stock on colour genetics.
What you are accepting
The tan point pattern itself carries no health risk whatsoever — it is ordinary canine colour genetics, present across many breeds. Every risk attached to this colour comes from the dilution half: colour dilution alopecia, and the insurance loading that a growing number of UK insurers now apply to diluted coats.
Worth being clear-eyed about the trade. You are paying roughly triple a brindle for a pattern that is cosmetically striking, genetically straightforward, and brings one specific dermatological risk with it.
Health and cost considerations for this colour:
- Carries the dilution genotype and colour dilution alopecia risk
- Not Kennel Club recognised
- Requires stacking two recessives, narrowing the breeding pool

Common questions
How much is a blue and tan French Bulldog in the UK?
Typically £4,500 to £9,000, reflecting the difficulty of stacking two recessive genes rather than any scarcity of the genes themselves.
Are blue and tan French Bulldogs healthy?
The tan point pattern carries no health risk of its own. The dilution half carries the risk of colour dilution alopecia, which affects only diluted dogs and cannot be screened out other than by avoiding the genotype.
Can blue and tan French Bulldogs be registered?
They can be registered as a non-standard colour but cannot be shown, as neither dilution nor tan points appear in the breed standard.
