To understand this a bit more, we will have to dive into some science.
As with all other traits, long hair is caused by the presence of a certain pair of genes.
In dogs, this is called the Fibroblast Growth Factor, or FGF.
Due to their ancestry, Fluffy Frenchies can possess this gene.
With advances in technology, it has become possible to study the genetic structure of Frenchies, and scientists in Australia have established without a doubt that the long hair gene is present in the French bulldog DNA.
How come some Frenchies have short hair while others have long?
Two types of genes code for hair length in Frenchies: short hair (Sh) and long hair (Lh). The short hair gene is more dominant than the long hair gene.
This means that if these two genes appear together (Sh/Lh), the Sh gene will be expressed while the short gene will be hidden.
So the dog will have short hair, even if it also has the Lh gene.
If the dog has two short genes (Sh/Sh) it will obviously also have short hair.
The dog will only have long hair if it has two long hair genes (Lh/Lh).
How would you go about breeding a long-haired Frenchie?
You would have to pair two Frenchies which both have the Lh gene.
If you breed two Frenchies with the Sh/Lh combination, then only 1 in 4 of their pups will have long hair.
If you breed two Frenchies which both have the Lh/Lh combination, all of their pups will have long hair.
Are there mix-breed long-haired French bulldogs?
Yes. Sometimes unscrupulous breeders have crossed Frenchies with long-haired Chihuahuas or Pekinese and passed them off as purebred long-haired Frenchies.
You can, however, ascertain whether a Frenchie is purebred by checking to see if they have purebred pedigree certificates.
I hope this little bit of science has put your fears about fake purebred long-haired Frenchies to rest.
How Much Are Fluffy French Bulldogs?
Breeding French bulldogs is not as easy as they have so many special requirements.
They require high-quality housing and food to keep them healthy.
A Frenchie could cost an average of $1500 to $3500. Fluffy Frenchies require even more time because you can only breed dogs you are sure will bear long-haired Frenchie puppies.
This means that you may have to get their genetic profile examined by scientists to determine whether they are purebred or not.
Frenchies have been known to cost up to $100,000.
10 Facts about Long-Haired French Bulldogs
1. Cesarean Section
Long-haired French bulldogs have very narrow hips, which makes it difficult for them to give birth in the normal way.
To make delivery less risky, they deliver through C-section.
2. Different Colors
Fluffy Frenchies come in different colors, including strange ones like blue, chocolate and lilac.
These are of course more expensive. They also come in typical colors like white, black and fawn.
3. Inability to swim
Due to their short stature and short snouts, fluffy Frenchies can’t swim.
Their legs are too short and they would not be able to keep their noses out of the water.
They would also tire out easily trying to paddle. So if you have a swimming pool, keep an eye on your Frenchies.
4. They Can’t Fly
Because of their short snouts, long-haired French bulldogs are more prone to breathing problems than other dogs.
The highly compressed air inside airplanes can cause fatal breathing problems for them.
A number of airlines don’t allow them on.

Fluffy Frenchies are naturally affectionate and friendly. They make great companions and can cheer you up when you’re down.
They also make friends easily with other dogs, so you don’t have to worry about constant doggy fights.
