The French Bulldog is one of the world’s most beloved breeds — adored for its friendly personality, compact size, and irresistibly charming face.
However, behind those cute wrinkles lies a serious issue: the breed is predisposed to a number of inherited genetic disorders, largely due to irresponsible and unethical breeding practices.
In this article, we’ll explore the most common genetic health problems found in French Bulldogs, how to recognize them, and what preventive measures responsible owners and breeders can take.
⸻
🩺 Breathing Problems (BOAS)
One of the most common issues in the breed is Brachycephalic Obstructive Airway Syndrome (BOAS) — a condition affecting dogs with shortened muzzles.
Symptoms:
• Loud snoring even while awake
• Labored breathing during exercise or in hot weather
• Bluish tongue (in severe cases)
• Collapse after physical exertion
Prevention & Treatment:
• Careful breeding selection — avoid dogs with severe breathing issues
• Maintain a healthy weight
• Surgical correction of the nostrils or soft palate if necessary
⸻
🐶 Skin and Dermatological Issues
French Bulldogs are prone to various skin diseases, some of which have a hereditary origin.
Most common:
• Ichthyosis — a genetic condition that causes dry, flaky skin.
Symptoms:
• Itching and frequent scratching
• Hair loss
• Redness and flaking
Prevention:
• Perform genetic testing before breeding
• Maintain proper hygiene and provide high-quality nutrition
• Minimize allergens in the dog’s environment

🩻 Orthopedic & Neurological Conditions
French Bulldogs are also predisposed to several serious bone and joint diseases, many of which are hereditary.
🧬 DMexon2 — Degenerative Myelopathy (DM)
What it is:
A progressive neurodegenerative disease of the spinal cord found in several breeds, including French Bulldogs. It leads to loss of coordination and, eventually, paralysis of the hind limbs.
Symptoms:
• Unsteady gait
• Dragging of the hind legs
• Difficulty standing up
• Gradual worsening over time
Inheritance:
Recessive — the dog must carry two copies of the mutated gene to develop the disease.
N/N result: Clear — not a carrier and will not develop the disease.
⸻
Hip dysplasia and Intervertebral disc disease (IVDD)
Symptoms:
• Stiffness or limping
• Pain when moving or when touched along the back
• Loss of coordination or paralysis in the hind legs
Prevention:
• X-rays and orthopedic evaluations before breeding
• Avoid high jumps in puppies
• Keep your dog’s weight within a healthy range
⸻
🧪 Other Hereditary Disorders
HUU — Hyperuricosuria & Hyperuricemia
What it is:
A genetic defect that affects uric acid metabolism, leading to the formation of urinary or kidney stones.
Symptoms:
• Frequent or painful urination
• Blood in the urine
• Urinary blockages
• In severe cases — kidney failure
Inheritance: Recessive
N/N result: Clear — no risk and not a carrier.
⸻
👁️ CMR1 — Canine Multifocal Retinopathy
What it is:
An inherited eye disease affecting the retina. It can cause impaired vision or blindness, particularly later in life.
Symptoms:
• Visible spots on the retina
• Blurred vision
• Partial or complete blindness
Inheritance: Recessive
N/N result: Clear — no disease or carrier status.
⸻
🛑 Cherry Eye (Prolapse of the Third Eyelid Gland)
“Cherry Eye” occurs when the gland of the third eyelid slips out of place, forming a red, fleshy bulge in the inner corner of the eye.
Prevention:
• Regular check-ups with a veterinary ophthalmologist
• Early intervention at the first sign of redness or irritation
⚠️ Cherry Eye cannot be detected through DNA testing, but it often has a hereditary component.
Breeding dogs that have experienced Cherry Eye is not recommended.
⸻
👁️ HC-T — Hereditary Cataract
What it is:
A genetic form of cataract that can develop in French Bulldogs even at a young age, potentially leading to total blindness if untreated.
Symptoms:
• Cloudy or grayish eye appearance
• Reduced vision
• Disorientation, especially in low light
Inheritance: Can be recessive or dominant, depending on the mutation type.
N/N result: Clear — no mutation, no risk of transmission.
⸻
🧫 CYST FB 1 — Cystinuria (French Bulldog Type)
What it is:
A metabolic disorder in which the kidneys fail to properly filter the amino acid cystine. This can lead to crystal and stone formation in the urinary tract, especially in males.
Symptoms:
• Difficulty urinating
• Blood in the urine
• Frequent urinary infections
• Acute kidney distress due to blockage
Inheritance: Recessive
N/N result: Clear — disease-free and not a carrier.

📝 Conclusion
Genetic disorders in French Bulldogs are a reality every responsible owner and breeder must acknowledge.
Despite their immense popularity and charm, the breed’s unique anatomy and genetic history make them more vulnerable to certain inherited health conditions.
Regular veterinary check-ups, preventive care, and most importantly, genetic testing, play a crucial role in stopping these diseases from being passed to future generations.
Responsible breeding isn’t just about producing puppies — it’s about preserving the health and future of the breed.
Every prospective owner should ask breeders for proof of health and genetic test results. And every ethical breeder should put health above profit.
Investing in prevention means investing in a healthier future — for individual dogs, and for the French Bulldog breed as a whole.
