Long haired French Bulldogs: Everything you need to know.

The French Bulldog has a very distinct look. Its face wrinkles, body shape and compact size make it one of the most recognisable dog breeds. Originally bred in France as companion dogs — descendants of toy bulldogs brought across the Channel by English lace workers — they are now popular pets in households all over the world. Aside from their physical features, French Bulldogs possess a sweet and playful personality that makes them the perfect addition to any family! Recently, long-haired French Bulldogs have taken the world by storm. They are quite rare and come with a high price tag. Here is everything we know about long-haired French Bulldogs.

How are French Bulldogs bred to have long hair?

French Bulldogs that have long hair carry the recessive long-hair gene — either L1 or L4. The gene works by reducing the ability of the FGF5 gene to signal to the hair follicle to stop hair growth 1.

To produce a long-haired French Bulldog, both parents must carry the L1 or L4 gene. They do not have to have long hair themselves, but they must carry the gene. A dog with one copy of the long-hair gene and one copy of the short-hair gene will pass the long-hair gene on to roughly 50% of its puppies — and if it is paired with another carrier, some of the litter can be born long-haired.

A dog with two copies of the long-hair gene will pass the gene to every puppy — and if both parents carry two copies, every puppy in the litter will be long-haired.

Does the AKC recognise long-haired French Bulldogs?

The American Kennel Club does not recognise long-haired French Bulldogs, as it views long hair as an undesirable trait. The official breed standard calls for a short, smooth coat, and lists coats "other than short and smooth" as a disqualification 2.

These are the colours and patterns the AKC recognises for the breed 3:

  • Brindle
  • Brindle and white
  • Cream

How long do long-haired French Bulldogs' coats grow?

Long-haired French Bulldogs' coats are only moderately longer than their short-haired siblings'. They typically grow 2-3 times longer than a short-haired French Bulldog's coat.

How much do long-haired French Bulldogs cost?

Long-haired French Bulldogs typically sell for a higher price than short-haired French Bulldogs. They sell as pets for prices higher than $10,000.

Why are long-haired French Bulldogs rare?

As fluffy French Bulldogs are not part of the AKC breed standard, breeders spent years deliberately breeding away from the long-hair genes. Producing one requires both parents to carry a recessive gene that most breeding lines were selected to avoid. As long-haired French Bulldogs have become more popular with pet owners in recent years, breeders have begun aiming to reproduce them.
