Meet the PACMAN! One of the Fluffiest French Bulldog you will ever see!

What is a Fluffy Frenchie? 

Fluffy Frenchies are purebred French Bulldogs carrying two copies of a deviant gene impacting their hair length. 

Wait, what? 

Yes, you read that right!

I spent a few days gathering as much information as possible about Fluffy French Bulldogs, also called Fluffy Frenchies or Long Hair Frenchies! 

If you want to understand what is a Fluffy French Bulldog, learn where their fluffiness is coming from, and learn other interesting facts, read on!

What Is A Fluffy Frenchie?

Before writing this article, I thought these dogs were mixed with another long-haired breed. 

What a surprise to discover that, in fact, they are purebred! Ok, ok, I hear you. They won’t win the next American Kennel Club Show! 

They are obviously not recognized by any French Bulldog Associations in all the countries, but one day, who knows? 

Genetically they are French Bulldogs, and that’s all that matters to me!

Visually, Fluffy French Bulldogs look like normal Frenchies except that they have long hair, especially around their face and ears.

Frenchies were already cute, but this version, I mean, look at that face!

Scientifically, a Fluffy Frenchie is a French Bulldog who carries two copies of an autosomal recessive gene affecting its hair length

It sounds scary, but it’s really not!

Autosomal recessive means that you would need to carry two copies of the gene, given by each of your parents, to display its attribute. 

If this is too complicated to understand, don’t worry!

Stay with me. I will explain in more detail later.

The gene in question is called Fibroblast Growth Factor 5 (FGF5) and regulates the hair cycle of many species, including humans!

Amazing right?

What Makes Fluffy French Bulldogs Fluffy?

According to this study from 2013, five known variants in the FGF5 gene are associated with long hair phenotypes in dogs.

The different alleles names which are basically the different variants of the gene FGF5, are:

  • FGF5:p.Cys95Phe is the most common across breeds, and for the sake of simplicity, we will call it (L). 
  • FGF5:c.578C>T (L2) occurs in Akita, Eurasier, Samoyed, and Siberian Husky breeds.
  • FGF5:c.556-571del16 (L3) occurs in the Eurasier breed. 
  • FGF5:c.559-560dupGG (L4) occurs in Afghan hounds, Eurasier breeds, and French Bulldogs. 
  • Finally, FGF5:g.8193T>A (L5) occurs in Afghan hounds.

So it means that for a French Bulldog to be fluffy, it must carry two alleles, L or L4. It could be any combination, L/L, L/L4, or L4/L4.

How Are Breeders Breeding Fluffy French Bulldogs?

Each gene comes in pairs. One gene in each pair comes from the mother and the other from the father.

The different genes possible to determine the hair length in French Bulldogs are (S) for Short Hair, (L), and (L4) for Long Hair.

 (S) is the dominant gene in French Bulldogs, meaning that one copy of this gene is enough for the puppy to have short hair.

Hence the different combinations of the trait are:

  • S/S = Short Hair French Bulldog. This is the most common French Bulldog with short hair.
  • S/L* = Long Hair Carrier French Bulldog. This Frenchie will also have short hair due to the dominance of the Short Hair Gene over the Long Hair Gene. Yet it will have the possibility to pass on the Long Hair Gene to its offspring.
  • L*/L* = Fluffy French Bulldog. The pure Fluffy Frenchie will pass on the Long Hair gene to its offspring.

L* means it can be an L or L4 variant of the gene

What Are The Differences Between A Fluffy Frenchie And A French Bulldog?

Besides the hair length, there are technically no other differences between a Fluffy French Bulldog and a “Short-hair” French Bulldog.

Yet, if you are considering getting a Fluffy Frenchie over a French Bulldog, there are a few things that you need to take into account before finalizing your decision.

  1. Fluffy Frenchies shedding problems. 

French Bulldogs are not shedding a lot, but they shed all year. When their hair is short and depending on their color, you might not even notice it. However, for Fluffy Frenchies, their hair being longer, this might become a problem.

  1. Fluffy French Bulldogs require more grooming.

Longer hair also means more grooming, I am tempted to compare it with humans, but it’s true, when you have short hair, washing your hair requires less time and effort than when you have long hair.

  1. Avoid hot and humid weather when owning a Fluffy French Bulldog

French Bulldogs tend to overheat, and Fluffy Frenchies are no exception. If you live in hot and/or humid countries, you might want to reconsider and get a “Short Hair” Frenchie instead.

  1. Fluffy Frenchies are expensive.

Fluffy Frenchies are more expensive than their short-haired siblings due to their rarity and difficulty breeding them.

Where Can You Get A Fluffy Frenchie?

While preparing for this article, I was surprised to see how many breeders have specialized in the Fluffy Frenchie.  While I cannot recommend any breeders in particular, these are my top tips to avoid backyard breeders if you are planning on buying a Fluffy French Bulldog:

  1. Make sure to buy from a reputable breeder specialized in this breed and the gene FGF5.
  2. Ask to see the parents and use the information collected here to challenge the breeder.
  3. Request genetic and genealogy results to ensure your future baby is healthy. Orivet provides Full Breed Profile for French Bulldogs, including the gene responsible for the fluffy trait we discussed earlier.
  4. Never buy from social media if the breeder doesn’t have a proper website with an established track record. 

What You Need To Know

This is Pacman! What a beauty!

The Fluffy French Bulldog is a unique and increasingly popular variation of the traditional French Bulldog breed. Their longer and fluffier coat results from a genetic mutation that affects the FGF5 gene. While they have the same cuddly personality as traditional French Bulldogs, prospective buyers should remember that this variation may require more grooming. Overall, the Fluffy Frenchie is a lovable and adorable variation of the French Bulldog breed that will make an excellent family dog.

Frequently Asked Questions:

How much is a Fluffy Frenchie?

Fluffy Frenchies cost between 4,000$ for standard colors all the way up to 50,000$ for rarer combinations.

What is a Fluffy Frenchie Mixed With?

Fluffies or Fluffy Frenchies are not mixed with any breed other than their own, the French Bulldog.

Are Fluffy Frenchies purebred?

Yes, 100%! As surprising as it sounds, Fluffy Frenchies are the product of two French Bulldogs mating.

What breed is a Fluffy French Bulldog?

A Fluffy French Bulldog is a French Bulldog carrying two copies of a gene affecting their hair length.

Are Fluffy Frenchies hypoallergenic?

Similarly to the short hair French Bulldog, Fluffy Frenchies are unfortunately not hypoallergenic.

Is A Fluffy French Bulldog rare?

Yes, they are because the gene responsible for their fluffiness is recessive, meaning both parents must transmit this gene for the offspring to show this trait.

Do Fluffy French Bulldogs shed?

Even though they are not shedding more than short hair French Bulldogs, they do. Their hair being longer, their shedding might be more apparent on clothes and furniture.

What is the history of the Fluffy French Bulldog?

Even though we don’t know when long-haired Frenchies first appeared, according to the French Bulldog history, we can assume that this mutation in the gene FGF5 appeared a long time ago. Probably passed on from one of the French Bulldog ancestors. However, the discovery of the gene mutation impacting hair length in French Bulldogs was in 2013, so again I would assume that specialized breeders started breeding them professionally only after this date.
