Blue eyes in French Bulldogs are caused by a genetic mutation known as the “dd” allele. This mutation affects the amount of pigment in the iris, resulting in a blue or partially blue eye color. French Bulldogs with blue eyes are rare, as the “dd” allele is less common than other eye color alleles.
The Merle gene, also known as the M-Locus, is responsible for most French Bulldogs that grow up with blue eyes. This gene is responsible for random pigment dilution or lightening of the nose, eyes, and fur. However, being a carrier of the Merle gene doesn’t always guarantee blue eyes in Frenchies or any dog.
Another gene can cause blue eyes in French Bulldogs is the ALX4 gene, which is responsible for melanin production in the iris, and mutations can lead to a lack of melanin, resulting in blue eyes.
The S-Locus gene, also known as the Piebald gene, is another gene that can cause blue eyes in French Bulldogs. This gene is responsible for the white spotting pattern on the coat and can also affect eye color. Frenchies with the Piebald gene are more likely to have blue eyes.
It’s important to note that blue eyes in French Bulldogs can also be a sign of albinism, a genetic condition that affects melanin production in the body. However, this is rare in Frenchies and is usually accompanied by other symptoms such as pale skin and sensitivity to light.
Eye Problems Associated with Blue Eyes
French Bulldogs with blue eyes are not uncommon, but they can be prone to certain eye problems. While the merle gene often causes blue eyes in Frenchies, other factors such as allergies, corneal ulcers, and keratoconjunctivitis can also contribute to eye problems.
Corneal ulcers are one of the most common eye problems associated with blue eyes in French Bulldogs. These ulcers, essentially open sores on the surface of the eye, can be caused by various factors including trauma, infection, and dry eye. Symptoms of corneal ulcers include squinting, tearing, and sensitivity to light.
Another eye problem affecting French Bulldogs with blue eyes is keratoconjunctivitis, an inflammation of the cornea and conjunctiva. Several factors including allergies, infections, and irritant exposure can cause this condition. Symptoms of keratoconjunctivitis include redness, discharge, and swelling of the eye.
In addition to corneal ulcers and keratoconjunctivitis, French Bulldogs with blue eyes may also be prone to other eye problems such as cherry eye, optic nerve hypoplasia, and juvenile cataracts. Cherry eye is a condition where the gland in the third eyelid prolapses, causing a red, fleshy mass to protrude from the eye. Optic nerve hypoplasia is a congenital condition with underdeveloped optic nerve, which can lead to visual impairment. Juvenile cataracts are also a common problem in French Bulldogs, which can cause blindness if left untreated.
Breeding and Blue Eyes
Breeding French Bulldogs with blue eyes can be a controversial topic among breeders. Some breeders may intentionally breed Frenchies for blue eyes, while others may avoid breeding for this trait due to potential health concerns.
Reputable breeders prioritize their dogs’ health and well-being over physical traits such as blue eyes. They will conduct genetic testing to ensure their breeding dogs do not carry any genetic defects that their offspring could inherit.
The American Kennel Club (AKC) also recommends that breeders prioritize health over physical appearance when breeding French Bulldogs. According to the AKC breed standard, blue eyes are considered a disqualification for showing in conformation events.
Blue eyes in French Bulldogs are often associated with the merle gene, which can cause various health issues such as deafness, blindness, and skin sensitivity. Therefore, it is important for breeders to carefully consider the compatibility of their breeding dogs to avoid passing on any genetic defects.
New owners must also be aware of the potential health risks associated with French Bulldog blue eyes. They should work with a reputable breeder who conducts genetic testing and prioritizes the health of their dogs.
Training and socialization are also crucial for French Bulldogs with blue eyes, as they may be more sensitive to light and noise. In addition, owners should take extra care to protect their dog’s eyes from the sun and bright lights.
Overall, breeding French Bulldogs for blue eyes should be done with caution and consideration for the health and well-being of the dogs. Reputable breeders and responsible owners can help ensure that Frenchies with blue eyes live happy and healthy lives.
Other Eye Colors in French Bulldogs
While blue eyes are a rare and enchanting trait in French Bulldogs, they are not the only eye color that can be found in this breed. Most Frenchies have dark-colored eyes that range from brown to black, however, other eye colors can be seen in French Bulldogs, and they can be just as beautiful as blue eyes.
The amount of melanin determines the color of a French Bulldog’s eyes in the iris. Melanin is a pigment that gives skin, hair, and eyes color. The more melanin a dog has in its iris, the darker its eyes will be. Conversely, the less melanin a dog has in its iris, the lighter its eyes will be.
French Bulldogs with a black coat color typically have dark brown or black eyes. Fawn Frenchies, on the other hand, usually have hazel or amber eyes. Brindle Frenchies can have a range of eye colors, including hazel, amber, and brown, and Lilac Frenchies often have blue or green eyes, while cream Frenchies usually have brown or hazel eyes.
Silver blue Frenchies, which have a coat color that is a combination of blue and silver, can have blue or gray eyes. Gray eyes are also possible in French Bulldogs that have a different colored eye, which is a condition known as heterochromia. This occurs when a dog has two different colored eyes, one blue eye and one brown eye.
While blue eyes are a rare and sought-after trait in French Bulldogs, many other eye colors can be found in this breed. The amount of melanin determines the color of a Frenchie’s eyes in the iris, and can vary depending on the dog’s coat color and genetics.
Cost and Rarity of Blue-Eyed French Bulldogs
Blue-eyed French Bulldogs are a rare and coveted breed, which can make them quite expensive. The cost of a blue-eyed French Bulldog can vary depending on several factors, including the breeder, location, and the dog’s lineage. A blue-eyed French Bulldog can cost anywhere from 3,000 to 10,000 or more.
The rarity of blue-eyed French Bulldogs is because it is a genetic mutation. According to Barkstory, the genetic mutation that causes blue eyes in French Bulldogs is known as the “dilution gene.” This gene affects the production of melanin, which gives color to the skin, hair, and eyes. Specialized cells called melanocytes in the eye’s iris produce melanin. When this gene is present, it dilutes the melanin in the iris, resulting in blue eyes.
In the United States, blue-eyed French Bulldogs are not recognized by the American Kennel Club (AKC) and are considered a fault in the breed standard. However, this does not diminish their popularity and desirability among dog lovers.
Due to their rarity and high demand, it is important to be cautious when purchasing a blue-eyed French Bulldog. It is recommended to only buy from reputable breeders who prioritize the health and well-being of their dogs. Researching the breeder and asking for health clearances and genetic testing is also important to ensure the dog is not prone to health issues.
In summary, blue-eyed French Bulldogs are a rare and expensive breed due to their genetic mutation. While the AKC may not recognize them, they are still highly sought after by dog lovers. Therefore, it is important to be cautious when purchasing a blue-eyed French Bulldog and to only buy from reputable breeders who prioritize the dog’s health and well-being.
