We take steps to make sure our French Bulldogs are healthy before breeding so we can ensure we produce quality, healthy, beautiful puppies.
We believe that whether you are looking for a show prospect or your new best friend, a healthy dog is the most important thing to purchase. There are many genetic problems that can manifest in the French bulldog. Presently, health testing as recommended by CHIC (Canine Health Information Center) and the FBDCA (French Bulldog Club of America) includes testing and certification of the heart, patella, hips, general CERF eye exam and DNA testing for Juvenile Cataracts. We recognize that it is unrealistic to expect every dog to pass everything all the time, however, that is why it is important to know the strengths as well as the areas that need improvement in a breeding program. Our French Bulldogs are certified clear or non-affected by disorders that can affect the French Bulldog breed. If we use a carrier of any genetic disorders, that carrier will always be bred to a clear and the litter will consist of puppies either of clears and/or carriers. Carriers will never be affected by any genetic disorders. It means they carry the gene and must always be bred to a dog who does not. We breed for health and quality and we will always make sure steps are taken for the best outcome from dogs with high qualities.

DNA testing we do on our French Bulldogs...
Canine Multifocal Retinopathy (CMR1)
Multifocal Retinopathy 1 is an inherited disorder of the Retina affecting several breeds of dog. Affected dogs typically present between 11 and 16 weeks of age with multiple discrete circular areas of retinal detachment with underlying fluid accumulation that are visible on an eye exam performed by a veterinarian. These blister-like lesions are typically found in both eyes and can appear gray, tan, orange or pink and vary in number, size and location. Progression of retinal changes is usually slow and new lesions are not noted after 6 to 12 months of age. Occasionally as affected dogs age, lesions appear to heal and are no longer visible on an eye exam. Generally the dog’s vision is not affected although vision loss has been described in some cases of multifocal retinopathy 1.
Cystinuria Type 3
Cystinuria type 3 is an inherited disease affecting kidney function in dogs. Dogs with cystinuria are deficient of a specific protein the kidneys use to transport cystine. Normal kidneys reabsorb cystine so that only small amounts pass into the urine. Dogs with cystinuria fail to reabsorb cystine, allowing large amounts to pass into the urine. Excessive cystine can form crystals and/or stones in the urinary tract, which can block the ureters or Urethra and stop the normal flow of urine. Symptoms of disease include straining to urinate, blood in the urine, frequent urination of small volumes or inability to urinate. Dogs with cystinuria often have recurrent inflammation of the urinary tract and if not treated, urinary stones can cause urinary tract infections, kidney failure and even death. Affects only mature and intact males.
Degenerative Myelopathy (DM)
Degenerative Myelopathy is an inherited neurologic disorder caused by a Mutation of the SOD1 gene known to be carried by French bulldogs. This mutation is found in many breeds of dog, though it is not clear for French bulldogs whether all dogs carrying two copies of the mutation will develop the disease. The variable presentation between breeds suggests that there are environmental or other genetic factors responsible for modifying disease expression. The average age of onset for dogs with degenerative myelopathy is approximately nine years of age. The disease affects the White Matter tissue of the spinal cord and is considered the canine equivalent to amyotrophic lateral sclerosis (Lou Gehrig’s disease) found in humans. Affected dogs usually present in adulthood with gradual muscle Atrophy and loss of coordination typically beginning in the hind limbs due to degeneration of the nerves. The condition is not typically painful for the dog, but will progress until the dog is no longer able to walk. The gait of dogs affected with degenerative myelopathy can be difficult to distinguish from the gait of dogs with hip dysplasia, arthritis of other joints of the hind limbs, or intervertebral disc disease. Late in the progression of disease, dogs may lose fecal and urinary continence and the forelimbs may be affected. Affected dogs may fully lose the ability to walk 6 months to 2 years after the onset of symptoms. Affected small breed dogs, such as the French bulldog, often progress more slowly than affected large breed dogs and owners may postpone euthanasia until the dog is paraplegic.
Hereditary Cataracts
Hereditary Cataracts is an inherited eye disease in French bulldogs. Cataracts are opacities in the lens of the eye caused by structural changes in lens proteins. A normal lens allows light to pass through it to the Retina in the back of the eye. Light cannot pass through the parts of the lens affected by cataracts and vision becomes blurry. Dogs with Hereditary Cataracts most commonly present within a few weeks to months after birth with small cataracts that are visible on a veterinary eye exam. Cataracts from this disease will eventually affect the whole lens in both eyes leading to complete blindness between 2-3 years of age. Of note, not all forms of cataracts are inherited and environmental factors such as UV damage can also play a role in the severity of disease.
HU-Hyperuricosuria
Hyperuricosuria is an inherited condition of the urinary system affecting several breeds of dog. The SLC2A9 gene codes for a protein that allows the kidneys to transport uric acid from the urine. Dogs with mutations in both copies of the SLC2A9 gene are predisposed to have elevated levels of uric acid in the urine, hence the name hyperuricosuria. Uric acid can form crystals and/or stones (uroliths) in the urinary tract. Dogs with hyperuricosuria most commonly present with symptoms of recurrent urinary tract inflammation, which include frequent urination, blood in the urine, and straining to urinate. They may also have loss of appetite, lethargy, weakness, vomiting and pain. Urinary stones in the bladder can cause urinary tract infections or more seriously, blockage of the Urethra. Both male and female dogs can be affected, but obstruction of urine flow is more common in males due to differences in anatomy. Although an x-ray can be used to exclude other types of stones, urate stones cannot typically be seen using x-rays and must be evaluated by ultrasound. Not all dogs with mutations in both copies of the SLC2A9 gene will have symptoms of disease, though they will have increased uric acid excretion in the urine.
Progressive retinal Atrophy, cone-Rod dystrophy 4 (PRA-crd4)
PRA is an inherited eye disease affecting dogs. PRA-crd4 occurs as a result of degeneration of both rod and cone type Photoreceptor Cells of the Retina, which are important for vision in dim and bright light, respectively. Affected dogs can show symptoms of vision loss or have signs of retinal disease on veterinary ophthalmologic exam by 3 years of age.

OFA testing we do on our French Bulldogs...
Cardiac Disease
Purpose: To gather data regarding heart diseases in dogs, and to identify dogs which are phenotypically normal prior to use in a breeding program. For the purposes of the registry, a phenotypically normal dog is defined as:
Congenital heart disease in dogs is a malformation of the heart or great vessels. The lesions characterizing congenital heart defects are present at birth and may develop more fully during perinatal and growth periods. Many congenital heart defects are thought to be genetically transmitted from parents to offspring; however, the exact modes of inheritance have not been precisely determined for all cardiovascular malformations. The most common congenital cardiovascular defects can be grouped into several anatomic categories. These anatomic diagnoses include:
Adult-onset or developmental cardiac diseases develop later in life and include for example; hypertrophic, arrhythmogenic and dilatative cardiomyopathies. Many adult-onset or developmental cardiac diseases may have a genetic component, however the exact modes of inheritance have not been precisely determined for all cardiovascular malformations.
Eye Certification
The purpose of the OFA Companion Animal Eye Registry (CAER) is to provide breeders with information regarding canine eye diseases so that they may make informed breeding decisions in an effort to produce healthier dogs. CAER certifications will be performed by board certified (ACVO) veterinary ophthalmologists.
The Eye Certification exam consists of indirect ophthalmoscopy and slit lamp biomicroscopy. It is not a comprehensive ocular health examination, but rather an eye screening exam. For example, Eye Certification exams do not entail measuring tear production, staining the eyes for the presence of corneal ulcers, or measuring intraocular pressures. Gonioscopy, tonometry, Schirmer tear test, electroretinography, and ultrasonography are not routinely performed; thus, dogs with goniodysgenesis, glaucoma, keratoconjunctivitis sicca, early lens luxation/subluxation or some early cases of progressive retinal atrophy might not be detected without further testing. If a serious ocular health problem (such as glaucoma) is suspected during the Eye Certification exam, the examiner will recommend a more comprehensive ocular examination. The diagnoses obtained during an OFA Companion Animal Eye Registry exam refer only to the observable phenotype (clinical appearance) of an animal. Thus it is possible for a clinically normal animal to be a carrier (abnormal genotype) of genetic abnormalities.
Hip Dysplasia
Canine Hip Dysplasia typically develops because of an abnormally developed hip joint, but can also be caused by cartilage damage from a traumatic fracture. With cartilage damage or a hip joint that isn’t formed properly, over time the existing cartilage will lose its thickness and elasticity. This breakdown of the cartilage will eventually result in pain with any joint movement.
No one can predict when or even if a dysplastic dog will start showing clinical signs of lameness due to pain. The severity of the disease can be affected by environmental factors, such as caloric intake or level of exercise. There are a number of dysplastic dogs with severe arthritis that run, jump, and play as if nothing is wrong and some dogs with barely any arthritic x-ray evidence that are severely lame.
Screenings for Hip Dysplasia are performed by a veterinarian with x-rays sent to OFA for grading and certification.
Patellar Luxation
The patella, or kneecap, is part of the stifle joint (knee). In patellar luxation, the kneecap luxates, or pops out of place, either in a medial or lateral position. Bilateral involvement is most common, but unilateral is not uncommon. Animals can be affected by the time they are eight weeks of age. The most notable finding is a knock-knee (genu valgum) stance. The patella is usually reducible, and laxity of the medial collateral ligament may be evident. The medial retinacular tissues of the stifle joint are often thickened, and the foot can be seen to twist laterally as weight is placed on the limb.
Examination and Certification
The dog is examined awake (chemical restraint is not recommended) and classified by the attending veterinarian according to the application and general information instructions. The veterinarian then completes the application form indicating the results of the dog’s patella evaluation. An OFA number will be issued to all dogs found to be normal at 12 months of age or older. The OFA number will contain the age at evaluation.
Purpose: To gather data regarding heart diseases in dogs, and to identify dogs which are phenotypically normal prior to use in a breeding program. For the purposes of the registry, a phenotypically normal dog is defined as:
- One without a cardiac murmur.
- One with an innocent heart murmur that is found to be otherwise normal by virtue of an echocardiographic examination which includes Doppler studies.

The lesions characterizing congenital heart defects are present at birth and may develop more fully during perinatal and growth periods. Many congenital heart defects are thought to be genetically transmitted from parents to offspring; however, the exact modes of inheritance have not been precisely determined for all cardiovascular malformations. The most common congenital cardiovascular defects can be grouped into several anatomic categories. These anatomic diagnoses include:
- Malformation of the atrioventricular valves
- Malformation of the ventricular outflow leading to obstruction of blood flow
- Defects of the cardiac septa (shunts)
- Abnormal development of the great vessels or other vascular structures
- Complex, multiple, or other congenital disorders of the heart, pericardium, or blood vessels
