The Blue French Bulldog is a rare and unique Frenchie color variation that has been gaining popularity in recent years. Known for their striking blue coat and charming personality, these blue dogs have become a favorite among dog lovers.

This dog will make you fall in love at first sight. Just like traditional Frenchies, these pups may need special care in the dental department because of their short muzzles. This involves frequent brushing and rising with dental mouthwashes

Blue Frenchies have become a highly sought-after color despite their higher price tag. Their loyal and affectionate personalities make them great companions for families and individuals alike. We turn to expert sources like The French Bulldog Bible to give you the complete guide to Blue Frenchies.

Frenchie breed enthusiasts always find new ways to modify them, adding hair length in fluffy Frenchies and different coat patterns in Merle Frenchies. Blue Frenchies take the spotlight with their coats with a gorgeous bluish hue (it’s really just a faded gray).

However, it is important to note that the Blue French Bulldog is a rare breed and can be quite expensive to purchase. Due to its unique coat color, it is highly sought after by many dog lovers, which has increased demand and price. 

But Blue is not a recognized coat color according to the American Kennel Club (AKC). This means Frenchies are not supposed to be blue and some breeders may breed them just for the more expensive color. So, if you’re looking for a blue Frenchie, be extremely careful of unethical breeders.

The dog’s rarity can also mean a hike in incompetent breeders who prioritize looks over health when breeding their dogs. You must, therefore, do your due diligence when researching Blue French Bulldogs puppies for sale.

Overall, the Blue French Bulldog is a beautiful and unique breed that is sure to capture the hearts of anyone who meets them.

History of Blue French Bulldogs

Blue French Bulldogs are a relatively new color variation of the French Bulldog breed. The breed itself originated in France in the 1800s by breeding toy versions of the English Bulldog. Here, they were believed to have been bred with Terriers and Pugs, giving them their bat ears. 

French Bulldogs were bred specifically to be companion dogs and were popular among the French bourgeoisie. The genes responsible for the bluish-gray hue in Blue Frenchies have always existed naturally in the breed. 

While blue French Bulldogs have become increasingly popular in recent years, they are not one of the standard American Kennel Club Frenchie colors. The only colors allowed by the AKC in the Frenchie Breed standard are:

  • Brindle, 
  • Fawn,
  • White, 
  • Brindle and white.

The breed standard does not specify blue, but it says that mouse and liver colors disqualifications. Mouse is the official term for the blueish or grayish color we call blue in Frenchies. It also applies to other dilutes like the Isabella Frenchie, or lilac Frenchie.

The breeding of blue French Bulldogs has been controversial due to concerns about health issues associated with the breed. Studies show that Frenchies today have a higher risk of over 20 common disorders.This controversy gets even hotter in Blue Frenchies because breeding for the coat color may fail to prioritize a healthy bloodline. 

Despite the controversy, blue French Bulldogs have become popular for those looking for a unique and affectionate pet. Their playful and friendly nature and distinct blue coloring make them a beloved addition to many families.

Blue Color Genetics In A French Bulldog

Blue Color Genetics In A French Bulldog

The blue color in French Bulldogs is a result of a rare genetic inheritance, just like in Cream Doxies and long hair in long-coated Dalmatians or agouti huskies.

The blue color is a dilution of the black color and is caused by the D-locus gene. The D-locus gene is responsible for the dilution of pigmented colors. 

The Dilution gene dilutes a solid black color, resulting in a faded gray that almost looks like blue. The gene works on Eumelanin which is the dark pigment responsible for black and brown colors in dogs.

A French Bulldog that carries two copies of the recessive dilution gene will have a solid blue coat. However, if a French Bulldog carries only one copy of the dilution gene, it will not be blue but will be a carrier of the blue gene. Two carriers bred together can produce blue puppies.

Blue vs. Isabella vs. Lilac and New Shade Frenchies: What’s the Difference?

One of the trickier aspects to pinpoint with dilute colors in Frenchies is to tell the difference between Isabella, lilac, and blue shades, especially with the appearance of so-called “new shade” French bulldogs

In short, blue is a dilute black dog, making for a dark, slate gray dog. Lilac is a lighter shade of blue with a slight red or chocolate tinge to the coat, while Isabella is a soft golden color with a bluish tinge.

Lilac has the same dilute gene, but with two extra cocoa alleles(genes). The video below explains how to tell whether you have a blue or lilac Frenchie:

Types of Blue French Bulldogs

The slate gray or charcoal blue frenchies actually come in a variety of patterns, making them incredibly unique. Let’s look at a few variations.

1. Blue and Tan French Bulldogs

2. Blue Merle French Bulldogs

2. Blue Merle French Bulldogs

The Blue Merle French Bulldogs exhibit a fascinating and eye-catching pattern with a marbled or mottled blue coat. This pattern is a result of the merle gene, which creates random patches of diluted color throughout the coat, often giving the impression of a watercolor painting. It’s essential to source Blue Merle French Bulldogs from responsible and ethical breeders to avoid health issues commonly associated with the merle gene.

3. Blue Brindle French Bulldogs

3. Blue Brindle French Bulldogs

The Blue Brindle Frenchies possess a striking coat that combines blue and brindle patterns. Brindle patterns consist of dark streaks or stripes on a lighter background, and when combined with the blue hue, the result is a visually stunning appearance. Like all French Bulldog puppies, Blue Brindle pups require special care and attention during their early development stages.

4. Double Blue Brindle French Bulldogs

Double Blue Brindle French Bulldogs boast an intense and captivating appearance due to the presence of two sets of brindle genes combined with the blue gene. The result is a coat with deep and prominent brindle striping, creating a truly unique and remarkable coloration.

5. Blue Fawn French Bulldogs

5. Blue Fawn French Bulldogs

The Blue Fawn Frenchies display a delightful fusion of blue and fawn colors in their coat. The blue appears as a diluted steel-grey shade over the face, while the fawn typically presents as a lighter, tan-like hue over the body. This combination results in a soft and pleasing appearance that’s highly cherished by Frenchie enthusiasts.

6. Blue Pied French Bulldogs

Blue Pied French Bulldogs have a predominantly white coat with distinct patches of blue coloration. The blue patches can vary in size and distribution, creating a charming and quirky appearance. Blue Pied Frenchies are loved for their unique and irregular coat patterns.

7. Long-Haired French Bulldogs

In recent years, another captivating variation of the French Bulldog has been gaining attention – the Long-Haired French Bulldog. Unlike the traditional short and sleek coat seen in standard Frenchies, this unique type possesses a luxurious and flowing coat with longer hair.

The Long-Haired French Bulldog is not a separate breed but rather a result of a recessive gene mutation that occasionally appears in French Bulldog litters. This gene causes the coat to grow longer than usual, creating a distinct and charming appearance. As a relatively rare variation, Long-Haired French Bulldogs have been a subject of fascination for breed enthusiasts and pet lovers alike.

Blue French Bulldogs are known for their affectionate and playful personalities. They are loyal, affectionate, friendly, even-tempered, and happy dogs. They love snuggling with family and make excellent listening partners with their high empathy. However, they are known for being feisty, dramatic, and sassy.

They are also known for their adaptability and can thrive in different living situations, whether it’s in an apartment or a larger home. These pups look like there are no thoughts behind those bug eyes, and true to that, they’re not the brightest.

With an intelligence score of 109 out of 139 dogs, what Blue Frenchies lack in brilliance, they make up for in resilience and a willingness to please. Positive reinforcement is necessary for training. Also, knowing how to discipline these sensitive pups dog without punishing them is vital. 

Suitability With Kids and Pets

These dogs are generally good with children and other pets and are not known to be aggressive. They should never be left around small kids without supervision to prevent accidents. Like any dog, early socialization and training are important to ensure that they develop good behavior and manners.

Caring for a Blue French Bulldog


When it comes to feeding a blue French Bulldog, it is important to choose high-quality dog food that is appropriate for their age, size, and activity level. Feeding them a balanced diet that includes protein, healthy fats, and carbohydrates is essential for their overall health. 

It is important to note that blue French Bulldogs tend to overheat, so it is recommended to avoid feeding them during the hottest parts of the day. Additionally, they should always have access to clean water to stay hydrated.


Blue French Bulldogs are a small breed, so they do not require a lot of exercise. They need about 30 to 45 minutes of short walks broken into two segments. They also need mental stimulation, like puzzles, to keep their minds occupied. 

It is important to avoid overexerting them, especially during hot weather, as they are prone to overheating. It is also essential to provide them with plenty of shade and water during outdoor activities.

How to Groom a Blue French Bulldog

Blue French Bulldogs have a short, smooth coat that is easy to maintain. These easy grooming steps will keep your Blue Frenchie looking their best.

  1. Regular brushing with a soft-bristled brush can help remove loose hair and keep their coat shiny and healthy.
  2. Brush their teeth at least twice a week and use a dental rinse in between to prevent tooth decay.
  3. Bathing with a quality dog shampoo should be done monthly or as needed, but not too frequently, as it can dry out their skin.

Make sure you dry them thoroughly with a towel or reusable doggy wipes. This prevents moisture accumulation in the wrinkles to prevent issues like infection and itching after grooming.

  1. Their nails should be trimmed monthly with pet clippers to prevent overgrowth and discomfort, 
  2. The ears should be cleaned regularly with dog ear wipes to prevent infections.

Health Issues In Blue Frenchies

Health Issues In Blue Frenchies

Like any other dog breed, Blue French Bulldogs are prone to certain health issues. These include:

  • Color Dilution Alopecia (CDA). This is a genetic condition that affects dogs with diluted coat colors, such as blue. CDA causes hair loss, dry and itchy skin, and skin infections. 
  • Brachycephalic Airway Syndrome (BOAS): the shortened snout causes multiple breathing issues in Blue Frenchies, like wheezing and breathing difficulties. A study showed that BOAS reduced short-snouted breeds’ lifespans by three years.
  • Stenotic nares, where the narrow nostrils make breathing harder
  • Luxating Patellar where the knee cap falls out of place
  • Hip dysplasia where the hip and thigh don’t properly connect
  • Skin fold dermatitis: an infection due to moisture and particles in wrinkles. Research has shown that flat-faced breeds are susceptible to the condition
  • Eye problems like cherry eye ( causes pink bumps on the side) and glaucoma 
  • Ear infections (and even deafness) due to their bat ears
  • Intervertebral Disc Disease (IVDD) that affects the spinal cord
  • Dental issues, allergies, food sensitivity, and obesity 

Training a Blue French Bulldog

Training a blue French Bulldog can be a rewarding experience, but it requires patience, consistency, and positive reinforcement. It is important to start training your Frenchie as early as possible, ideally when they are still puppies. Here are some tips for training your blue French Bulldog:

Socialization is crucial for any dog, but especially for Frenchies, who can be prone to aggression if not properly socialized. It is important to expose your blue French Bulldog to different people, animals, and environments from a young age. This can help them develop confidence and reduce fear and anxiety.

Teaching your blue French Bulldog basic commands such as “sit,” “stay,” “come,” and “heel” is essential for their safety and your peace of mind. Crate training and obedience are the other cornerstones in your Frenchie’s training. You can choose to take your pup to obedience class for even better results.

Ideal Blue Frenchie Home

  1. Apartment dwellers or people with small spaces (although they are adaptable to most environments as long as they live indoors).
  2. Non-allergic households. 
  3. People okay with a possibly higher vet bill (it’s essential to have pet insurance if you have a Frenchie).
  4. People who aren’t that active (while they need exercise, these dogs can’t keep up on runs or long hikes). 
  5. Owners that prefer a smaller companion dog with a giant personality.

Where to Get a Blue French Bulldog


Adopting a blue French Bulldog can be a great option for those who want to provide a loving home for a dog in need. Many animal shelters and rescue organizations have French Bulldogs available for adoption, including blue ones.

One option is to check with local animal shelters and rescue organizations. Some may have a waiting list, so it’s best to contact them early and express interest in adopting a blue French Bulldog.

Another option is to look for breed-specific rescues that specialize in French Bulldogs. These organizations often have a network of volunteers who foster dogs until they find their forever homes. We highly recommend you contact or donate to the French Bulldog Rescue Network.


One way to find a reputable breeder is to check with national and local French Bulldog clubs. These organizations often have breeder referral programs that can help connect potential buyers with responsible breeders. 

A good place to start is to contact breed clubs, like The French Bulldog Club Of America for a referral. In general, breed clubs are far stricter about health and temperament testing in breeders than then what kennel clubs are.

It’s also important to ask the breeder questions about their breeding practices, health testing, and the care they provide for their dogs. A responsible breeder should be willing to answer these questions and provide documentation to back up their claims.

Additionally, potential buyers should be wary of breeders who advertise “rare” or “exotic” colors, as these can be signs of unethical breeding practices. The American Kennel Club recognizes blue French Bulldogs, so there may be no need to pay extra for a “rare” color.
