What is a Blue French Bulldog?

Blue French Bulldogs are a result of a genetic mutation that causes their coat to have a blue-grey color. This is due to a dilution gene called “d” that affects the expression of the melanin pigment in the dog’s fur. The dilution gene is recessive, which means that both parents must carry the gene for their offspring to express the blue-grey color. Breeders may use genetic testing to determine if their dogs carry the dilution gene before breeding.

What Makes Blue French Bulldogs Blue?

Blue Frenchies get their distinct blue coloring due to a genetic mutation in the melanophilin gene (MLPH). This mutation affects the pigments that are responsible for creating a black coat and causes them to appear as a silver or grey shade instead. This means that the black color in their fur is diluted, resulting in the blue hue that is characteristic of this breed. While the mutation is responsible for their unique coloring, it also increases their susceptibility to certain health conditions, including color dilution alopecia.

Blue French Bulldog Characteristics

Blue French Bulldogs are a smaller and more compact version of the standard French Bulldog, with a muscular and well-rounded body. They have a distinctive blue-gray coat that can range from a light blue to a darker slate color. Their coat is short and smooth, and they have a characteristic “bat ear” that stands upright.

Blue French Bulldog Size & Lifespan

Blue French Bulldogs typically weigh between 16 and 28 pounds and stand 11 to 12 inches tall at the shoulder. They have a life expectancy of 10 to 12 years and are generally healthy, although they may be prone to certain health issues, such as hip dysplasia and breathing problems.

Common Blue Color Variations

Here are some of the most common color combinations for blue French Bulldogs:

  1. Solid Blue: This is the most common color for blue French Bulldogs, with a solid gray-blue coat.
  2. Blue and Pied: This combination features a blue coat with white markings on the chest, feet, and face.
  3. Blue and Tan: This combination features a blue coat with tan markings above the eyes, on the cheeks, and on the legs.
  4. Blue Brindle: This combination features a blue coat with black brindle stripes.
  5. Blue Fawn: This combination features a blue coat with fawn-colored markings on the face, ears, and feet.
  6. Blue Sable: This combination features a blue coat with sable markings, which are a mix of black, brown, and gray.
  7. Blue Merle: This combination features a blue coat with black or gray merle markings, which create a marbled or dappled effect on the coat.

It is important to note that while these are the most common color combinations for blue French Bulldogs, there can be variations within each color. For example, a blue and tan French Bulldog may have different shades of blue and tan, or the markings may be in different locations on the body.

Blue French Bulldog Temperament

Blue French Bulldogs are known for their friendly and affectionate nature. They are loyal and devoted to their owners and love to cuddle and play. They are also intelligent and easy to train, although they can be stubborn at times.

Blue French Bulldogs are a social breed and enjoy the company of their owners and other dogs. They are generally good with children and make excellent family pets. However, they may not be suitable for households with very young children, as their small size and delicate nature may make them vulnerable to accidental injury.

Care Requirements

Blue French Bulldogs have specific care requirements that are important to consider before bringing one into your home. Here are some key factors to keep in mind:

  1. Grooming: Blue French Bulldogs have a short, smooth coat that is easy to care for. They should be brushed once a week to remove loose hair and keep their coat shiny. They may also need their wrinkles cleaned to prevent skin infections.
  2. Exercise: Blue French Bulldogs are a relatively low-energy breed and do not require a lot of exercise. They should be taken for short walks or play sessions several times a day to prevent obesity and keep them mentally stimulated.
  3. Health: Blue French Bulldogs may be prone to certain health issues, such as breathing problems, hip dysplasia, and skin allergies. It is important to keep up with regular vet checkups and monitor their health closely.
  4. Diet: Blue French Bulldogs have a tendency to overeat and can become overweight quickly. They should be fed a high-quality, age-appropriate diet and given treats in moderation.
  5. Training: Blue French Bulldogs are intelligent and easy to train, but they can be stubborn at times. Positive reinforcement training methods are the most effective, and consistency is key.

Blue French Bulldog Health Concerns

While Blue French Bulldogs are generally healthy, they may be prone to certain health issues that are common in the French Bulldog breed. One of the most significant health concerns is brachycephalic airway syndrome, which is a condition that affects dogs with flat faces and short snouts. This can cause breathing difficulties and other respiratory problems, such as snoring and overheating. Blue French Bulldogs may also be prone to hip dysplasia, skin allergies, and eye problems.

Color Dilution Alopecia

Unfortunately, a skin condition called color dilution alopecia, often abbreviated as CDA, tends to affect Blue Frenchies more than other breeds. This hereditary disease leads to flaky, itchy skin, hair thinning and loss, and dry skin.

To summarize color dilution alopecia, it is commonly diagnosed by ruling out other possible issues, and the age of onset is typically between 6 months to 2-3 years of age. It is more common in Blue/Lilac/Blue Fawn dogs due to genetic factors, and unfortunately, there is no cure. However, the condition can be managed through moisturizers, dietary changes, vitamin supplementation, and other methods.

Signs of color dilution alopecia include hair loss that starts as patches, thin hair, a dry and dull coat, and hyperpigmentation.

Can We Test For Color Dilution Alopecia?

Regrettably, there is currently no test for color dilution alopecia as the specific gene responsible for the condition remains unknown.

Blue French Bulldog Cost

When it comes to the cost of a Blue French Bulldog, they are typically more expensive than standard French Bulldogs due to their rarity and demand. Prices can vary depending on the breeder, location, and other factors, but they can range from $4,000 to $10,000 or more. It is important to do your research and choose a reputable breeder who prioritizes the health and welfare of their dogs.
