The French Bulldog is a medium sized dog with a short, easy to manage coat. Typically he is a dog with a great personality who is up for any kind of fun but is not noisy or boisterous. He will adapt to most lifestyles, but obviously would prefer to have his own garden if possible. He needs daily exercise and opportunities to play.
Inbreeding Coefficient - COI
(Should be as low as possible)
The UK Kennel Club breed average COI is 4.8% - see 'A Beginners Guide to COI'
Effective Population Size - EPS132.28
EPS is a measure of how many individuals are contributing genetically to a breed population. It is a measure of the size of the gene pool in a breed. Lower than 100 is considered critical by conservationists and below 50 brings a breed close to extinction. For more information see the Kennel Club article.
Health and Welfare Problems due to Conformation
(Body shape and physical characteristics)
- The French Bulldog has a short (brachcephalic) nose and corresponding head shape abnormalities. This may result in Brachycephalic obstructive airway syndrome (BOAS) (breathing difficulties and sometimes collapse of the larynx)
- This head shape can also produce an elongated soft palate which is a further cause of breathing problems, particularly during exercise.
- Narrowed nostrils also restrict oxygen intake.
- Difficulties with panting causing overheating.
- Cleft lips and palates can occur.
- There are birthing difficulties due to the large head of the puppies and small pelvis of the mother.
- Cherry eye (rolling out of third eyelid and eversion of tear gland – due to prominent eyes)
- Hip dysplasia (malformation of the hip joint causing pain and disability): breed mean score 13.5 (parents should be lower)
- Eye disease: Hereditary cataract (HC) (annual testing)
Identified by the UK Kennel Club as part of their Breed Health and Conservation Plan
Estimated Breeding Values (EBVs) are now available for Hip Dysplasia and Elbow Dysplasia:
DNA Tests Available
- Hereditary cataract (HC- HSF4) (early onset)
- Degenerative Myelopathy (DM) (causes progressive weakness of back legs, paralysis and incontinence)
- Progressive Retinal Atrophy (PRA-cord 1)
- Hyperuricosusria (HUU)
- Canine Multi-focal Retinopathy (CMR)
Unofficial (Breed Club) Schemes
- Microchip identification
- Veterinary examination
- Patella test
- Cardiologist heart test
- Spine X-ray and evaluation
Ask the breeder to show you the certificates for the above tests/screening for both parents. If any of the above tests have not been considered necessary by the breeder (and there may be good reasons), ask her to explain why.
Other Diseases Reported
(For which there are currently no genetic or screening tests for sire or dam)
- Entropion (inward turning eyelashes)
- Histiocytic ulcerative colitis (inflammatory bowel disease causing chronic diarrhoea)
- Patellar luxation (dislocation of kneecap)
- Cancer (brain tumour)
- Haemophilia (bleeding disorder)
- Hemivertebrae (malformation of the spinal column, causing progressive hind leg weakness and spinal pain in some dogs)
- Intervertebral disc disease (disc damage with compression of the spinal cord, often causing paralysis of the hind limbs)
- Congenital deafness (associated with coat colour)
- Distichiasis (double row of eyelashes causing eye irritation and pain)
- Pannus (abnormal growth of tissue over cornea)
- Urolithiasis (stone formation in urinary system)
- Cleft lips and palates can occur
- Heart disease: Pulmonic stenosis (narrowing of the pulmonary artery, with risk of heart failure)
Ask the breeder about the medical history of the parents, grandparents and great grandparents. Consider carefully whether to purchase a puppy if some of these or other diseases are in the family line.
Ask about the breeder’s policy in cases of serious genetic diseases occurring to your puppy in later life. Good breeders will request to be informed of such events in order to improve future breeding decisions. Some breeders will also agree to contribute towards medical costs or refund purchase price.
You are strongly advised to buy from a breeder who uses (or is prepared to use) the RSPCA / BVA AWF Puppy Contract and Puppy Information Pack (PIP): www.puppycontract.org.uk
You are also advised to buy from a breeder who follows the Dog Breeding Reform Group’s (DBRG) Standard for Dog Breeding:
