A pied French Bulldog has a mostly white coat with patches of color, usually brindle or fawn. Pied is a standard, recognized Frenchie color, not a rare or "exotic" one. Because the white comes from a pigment gene that can also affect the inner ear, it is worth asking for a hearing test before you bring a pied puppy home.

What is a pied French Bulldog?

"Pied" is short for piebald: a white base coat with colored patches. The Royal Kennel Club standard describes a brindle pied as "white predominates with brindle patches" and a fawn pied the same way with fawn patches. It also says white Frenchies are classified with pieds for show purposes.[4]

The FCI standard, used in most of Europe and Latin America, calls brindle with "moderate or significant" white spotting "so-called pied," and fawn with white spotting "fawn and white."[3] In everyday use, most US owners call any mostly white Frenchie with patches a pied.

Are pied French Bulldogs rare? No. Pied is one of the traditional colors listed in all three major standards. Sellers who market pied puppies as "rare" are using a sales label, not a genetic fact.

Pied French Bulldog colors

The patches on a pied Frenchie take whatever base color the dog's other genes produce. The standards treat these combinations differently:

Pied typeAKC (US)Royal Kennel Club (UK)
Brindle pied (white with brindle patches)Accepted (brindle and piebald are listed markings)Accepted
Fawn pied (white with fawn patches)AcceptedAccepted
White with true black patches (no brindle)Disqualification ("black and white," "white with black")Not a listed color
Blue, lilac or merle piedDisqualification (the standard names "blue," "blue fawn," "liver" and "merle")Not breed standard; merle puppies not registered

This is how the AKC standard and the Royal Kennel Club treat pied.[2][4][7] Note the AKC detail: "Black means black without a trace of brindle." Many pied Frenchies that look black-and-white actually have dark brindle patches, which are acceptable.[2]

A "merle pied" is not just a pied variation. Merle is a separate gene with its own health risks. Read our guide on merle French Bulldog health risks before you consider one.

Pied genetics: the S locus and MITF

The UC Davis Veterinary Genetics Laboratory explains that piebald (random white spotting) is associated with a DNA variant in the MITF gene, at what geneticists call the S locus. French Bulldogs are on its list of breeds appropriate for this test.[1]

  • N/N: no copy of the variant. No piebald pattern is expected, although other genes can still add white markings.
  • N/S: one copy. Depending on the breed, the dog may show no white or some white. It passes the variant to about half its puppies.
  • S/S: two copies. The dog is expected to show white, sometimes very extensive, and passes the variant to all its puppies.

UC Davis notes that the variant acts as recessive in some breeds and as incompletely dominant in others, and that "additional mutations in MITF or other white-spotting genes" also change how much white a dog shows.[1] This may help explain why pied dogs can show very different amounts of white.

Pied is independent of coat dilution. A "blue pied" carries both the piebald variant[1] and the recessive dilute gene, which turns black pigment gray-blue.[8] Dilute coats have their own skin concern; see blue French Bulldog hair loss.

Pied French Bulldogs and deafness

The Merck Veterinary Manual says congenital deafness in dogs "is associated with white pigmentation" and that the most common type, cochleosaccular deafness, is most common in dogs with the piebald or merle genes. It develops within 1 to 3 weeks after birth and can affect one ear or both.[5]

The reason is the inner ear. A structure called the stria vascularis needs pigment cells (melanocytes) to work. When white-spotting genes leave it without those cells, it degenerates and the ear can no longer detect sound.[9] The French Bulldog is on the LSU list of breeds with reported congenital deafness.[10]

Keep this in proportion. Most pied Frenchies hear normally, and we did not find a reliable published deafness rate for pied French Bulldogs specifically. What the research does show, across breeds, is that pigment-related deafness often comes with blue eyes, and blue-eyed dogs are statistically more likely to be deaf.[9] The FCI standard is cautious for the same reason: all-white Frenchies are "admitted but not bred for, because of a risk of deafness," and deafness is a disqualifying fault.[3] For more detail, see our guide to white French Bulldog deafness.

BAER hearing test

A pied puppy that is deaf in one ear usually behaves like any other puppy. Merck warns that unilateral deafness "may go undetected" without a BAER (brainstem auditory evoked response) test, which it calls the most definitive diagnosis.[5]

  • It records the brain's electrical response to clicks, one ear at a time.
  • It usually takes about 10 to 15 minutes and normally does not need sedation.[6]
  • Veterinary schools, neurology clinics and some breed events offer it. Ask the clinic about the youngest age they test.

For breeders, Merck says BAER testing plus informed selective breeding is often the best available tool to lower deafness in a breed, and that dogs deaf in one ear pass on a higher risk if bred.[5]

Pied French Bulldog puppies: what to ask breeders

Searches for pied French Bulldog puppies and breeders often lead to price lists. Color should never be the main reason to choose a puppy; the Royal Kennel Club puts it plainly: "Health and temperament should always be a priority over colour."[7] Before you pay a deposit, ask:

  1. "Has this puppy had a BAER test? Can I see the result for each ear?"
  2. "Are either parent merle or cryptic merle? Do you have M-locus DNA results?"
  3. "What breathing, eye, hip and other health tests do the parents have?" Our breeder health tests guide lists them.
  4. "Have any puppies from these parents been deaf?"

If a seller charges extra because a puppy is pied but cannot show a hearing test, take that as a warning sign. The puppy health checklist covers the rest of what to check at pickup.
