Two of the most pop breeds of dog inwards the USA, Canada, too the U.K. are French Bulldogs too Labrador Retrievers. In fact inwards 2018, French Bulldogs knocked Labrador Retrievers off the top spot inwards the U.K. for the offset time.
Because pedigree dogs are bred from a unopen genetic pool, they tin develop wellness issues related to the breed. As well, of course, whatsoever domestic dog tin survive affected past times diverse canine conditions. In the UK, a large database (VetCompass) that records details of top dog assist vet visits has been used to discovery out what kinds of wellness problems certainly breeds have, too how long they tend to live, on average (O’Neill et al, 2018; McGreevy et al, 2018). The studies are based on wellness records for 2013.
Having a meliorate agreement of how mutual unlike disorders are inwards exceptional breeds agency that breeders too Kennel Clubs tin brand plans to improve the wellness of those breeds. As well, it agency that domestic dog owners accept a meliorate persuasion of the questions to inquire a breeder, too veterinarians tin operate along an oculus out for the atmospheric condition that are most mutual inwards those breeds.
It’s of import to banker's complaint at that spot are some limitations to the data. When the overall numbers of a breed inwards the database are small, when the numbers of that breed are growing rapidly, or when the average historic menstruum of the dogs inwards the database is young, the information may non reverberate all the issues affecting the breed, some of which tend to seem equally dogs age. This applies to French Bulldogs inwards the sample.
So which wellness issues tend to impact French Bulldogs too Labrador Retrievers?
French Bulldogs

Number of dogs inwards the database: 2228
Median historic menstruum at fourth dimension of study: 1.3 years
Median lifespan: 3.6 years
Most mutual causes of death: Brain disorder too spinal disorder. However, given the immature historic menstruum of dogs inwards the sample, this may modify equally the dogs historic menstruum equally they are non quondam plenty for many diseases associated amongst quondam age.
Most mutual conditions: 72.4% had at to the lowest degree 1 condition. The most mutual disorders were otitis externa (affecting 14%), diarrhea (7.5%), too conjunctivitis (3.2%). Other mutual atmospheric condition were the nails beingness equally good long too skin-fold dermatitis. In this sample, 2.7% had an upper respiratory tract disease, too 2.4% had been diagnosed amongst Brachycephalic Obstructive Airway Syndrome. These rates are much lower than other studies, probable due to the immature historic menstruum of the dogs too one-year time-scale of the study.
Behaviour: Surprisingly, 2.3% of French Bulldogs were described equally aggressive, amongst this beingness the 13th most mutual status listed.
Colours: The most mutual colours were brindle too fawn.
Population growth: The rising inwards popularity of French Bulldogs is astounding. The newspaper reports that inwards 2004, French Bulldogs made upwards alone 0.02% of novel puppies inwards the database, too past times 2013 (the fourth dimension information was collected for this study) it had risen to 1.46%. Now, equally nosotros know from KC data, the French Bulldog is the most pop domestic dog breed inwards the UK.
It may survive that some issues typical of the breed would survive to a greater extent than probable to seem equally the dogs larn older, too that breeding practices modify equally a lawsuit of the increased need (e.g. a higher pct of dogs from puppy mills vs specialist breeders), too this may inwards plow impact the prevalence of genetic disorders.
Other info: The scientists write,
“With several of the most mutual disorders inwards French Bulldogs linked to their physical conformation (e.g. URT [upper respiratory tract] affliction too ophthalmological conditions), the increasing popularity of this breed is non necessarily a benign phenomenon. Increased need for dogs amongst extreme conformational features is suggested to survive detrimental to these dogs’ welfare both because of straight linked disorder run a endangerment too also because steeply increasing need may contribute to suboptimal breeding too welfare standards equally breeders too suppliers chop-chop endeavor to fulfil the heightened consumer demand.”
Labrador Retrievers

Number of dogs inwards the database: 33,320.
Median historic menstruum at fourth dimension of study: 4.9 years
Median lifespan: 12.0 years overall, only on average chocolate Labs alive 10.7 years compared to 12.1 for dark too xanthous Labs.
Most mutual causes of death: Musculoskeletal disorders too tumours were the most mutual causes of death.
Most mutual conditions: 61.6% of Labradors had at to the lowest degree 1 condition, too the most mutual were otitis externa (often called “swimmer’s ear”) inwards 10%, overweight too obesity (8.85%) too degenerative articulation affliction (5.5%). Lameness too periodontal affliction were the side past times side most mutual disorders. Chocolate labs were to a greater extent than probable to accept ear too peel diseases than dark too xanthous Labs.
Behaviour: In contrast to French Bulldogs, aggression did non characteristic inwards the listing of the twenty most mutual conditions. Undesirable deportment was listed for 1.5% of Labs, making it the 16th most mutual condition.
Colours: Labrador Retrievers come upwards inwards black, chocolate, too yellow. The most mutual colouring cloth was black, followed past times yellow. Chocolate was the to the lowest degree mutual only nevertheless made upwards 24% of Labs.
Other info: The number of Labrador Retrievers inwards the U.K. dropped significantly from 2004 until 2013 when the information for this study was collected. Male dogs weighed to a greater extent than than woman individual ones, too piece for females, spaying was non associated amongst overweight, for manlike individual dogs neutering was associated amongst the domestic dog beingness overweight or obese.
The scientists write,
“We were interested inwards the association amongst coat colouring cloth because chocolate pigmentation is recessive inwards dogs. So, if chocolate coat colouring cloth is desired inwards litters, breeders may survive motivate to breed from certainly lines that may inadvertently increment the ensuing puppies’ predisposition to certainly diseases. It is possible that a to a greater extent than restricted population cistron puddle has a higher wagon charge per unit of measurement of the affliction run a endangerment genes involved inwards ear too peel conditions.”
The overall wellness of French Bulldogs too Labrador Retrievers
These results exhibit the most mutual atmospheric condition affecting French Bulldogs too Labrador Retrievers, equally good equally changes inwards the popularity of these breeds.The finding that chocolate Labs tend to alive less long too are to a greater extent than probable to survive affected past times certainly atmospheric condition are interesting. Other enquiry has suggested personality differences betwixt chocolate Labs vs xanthous too dark Labs, at to the lowest degree according to possessor reports.
Because the sample of French Bulldogs was then young, they may non yet accept been diagnosed amongst congenital atmospheric condition associated amongst the breed. Research shows that French Bulldog owners typically pick out the breed because of it's appearance too personality, only many people are concerned nearly the wellness of this too other brachycephalic breeds. Here are some suggestions if yous love French Bulldogs only wish to consider alternatives too.
