How to check one before you pay — what the papers prove, what to look up, and the signs to walk away from.
Which breed fits your family?Six questions. The answer comes with the honest line for each breed.
Abyssinian
Abyssinians are one of the most perpetually active cat breeds that exists and generally dislike being held or restrained, which is the opposite of…
American Shorthair
The 'all-American working cat' story implies a hardy, mixed-heritage constitution, but this is a closed pedigree bred like any other purebred, and…
Balinese
A Balinese is essentially a Siamese in a long coat, which means it comes with the same small foundation gene pool and the same documented risk of…
Bengal
Bengals carry real wild ancestor genetics from the Asian leopard cat, and depending how many generations removed a kitten is from that wild parent…
Birman
Birmans are marketed as a calm, especially healthy longhaired breed, but they carry a distinctly higher-than-average rate of blood type B (and the…
British Shorthair
The round 'teddy bear' face and dense plush coat of the show standard sit on a breed that Cornell's feline health center lists among those with an…
Burmese
The extremely rounded, short-faced 'contemporary' Burmese head comes from a gene that is lethal in double dose — kittens born with two copies have…
Cornish Rex
The Cornish Rex's signature ultra-thin, guard-hair-free coat isn't just low-maintenance styling — it leaves the cat with little real insulation or…
Devon Rex
Devon Rex are talkative and constantly want to be involved in whatever you're doing, including waking you up, and despite low shedding they are not…
Domestic Shorthair
The 'ordinary' shelter cat with no pedigree is, on average, the genetically healthiest cat you can get — a large insurance-data study found purebred…
Egyptian Mau
The Egyptian Mau's spots are entirely natural — it's the only naturally spotted domestic cat breed, not a wildcat cross — but it does carry a real,…
Exotic Shorthair
The Exotic Shorthair is a Persian in a plush short coat, bred to the same extreme flat-faced standard, which means it inherits the same…
Himalayan
A Himalayan is a Persian with Siamese coloring, which means it inherits the Persian's flattened face and everything that comes with it — chronic…
Maine Coon
Maine Coons are marketed as a robust, 'naturally healthy' breed, but a lab analysis of thousands of samples found roughly a third of Maine Coons…
Manx
The same gene that gives Manx cats no tail also frequently disrupts how the spinal cord forms — one cited study found spina bifida in 16% of Manx…
Munchkin
Munchkin's short legs come from a dwarfism gene, breeding two Munchkins together kills roughly a quarter of the resulting kittens before birth…
Norwegian Forest Cat
This breed is marketed as a hardy, naturally-evolved landrace with few health problems, which is true for most individuals, but it carries a rare…
Ocicat
Despite looking exactly like a wild ocelot, the Ocicat has zero wild-cat ancestry — it's a 100% domestic breed built from Abyssinian, Siamese and…
Oriental Shorthair
Oriental Shorthairs are Siamese in a different coat, including the same nonstop, opinionated vocalizing — often described as sounding more like a…
Persian
The flat 'doll face' that wins in the show ring is extreme brachycephaly by another name, and it comes with lifelong breathing difficulty, constant…
Ragamuffin
Ragamuffin breeders lean hard on the phrase 'hybrid vigor' from outcrossing to domestic longhairs, but the breed's own official CFA page still lists…
Ragdoll
Ragdolls are sold almost entirely on their limp, placid 'floppy' temperament, but that same breed carries a specific inherited heart-disease…
Russian Blue
Russian Blues are one of the few purebred cats without a well-documented breed-specific genetic disease, so the real caveat here is temperament…
Savannah
A Savannah is a serval hybrid, and how legal it is to own one depends entirely on the generation (F1 being closest to the wild serval, F5 and later…
Scottish Fold
Every Scottish Fold's folded ears are caused by osteochondrodysplasia, a cartilage and bone-growth disorder that International Cat Care confirms…
Siamese
The Siamese's famous 'talking' is not occasional chatter but a loud, persistent, opinionated yowl, and a bored or ignored Siamese will use it at 3am…
Siberian
Siberians are marketed as 'hypoallergenic,' but no cat breed is allergen-free — every cat produces the Fel d 1 protein that triggers allergic…
Somali
Because it's a longhaired Abyssinian, the Somali inherited the Abyssinian's unusually high rate of pyruvate kinase deficiency — in tested Somali…
Sphynx
Sphynx cats are sold as hypoallergenic because they lack fur, but the protein that actually triggers most cat allergies (Fel d 1) comes from skin and…
Tonkinese
The Tonkinese is a Siamese-Burmese cross bred to be a 'best of both' companion, but that also means an extremely vocal, attention-demanding cat that…
Turkish Angora
A white Turkish Angora — especially one with blue eyes — carries a meaningfully higher risk of being born completely deaf, a well-documented side…
Turkish Van
The Turkish Van's popular reputation as a friendly, water-loving lap cat doesn't fully match the data — a 2021 behavioral study found the breed…
Airedale Terrier
As the largest terrier breed, the Airedale keeps a full terrier prey drive and stubborn streak in a 50-plus-pound body, and breed mortality surveys…
Akita
The AKC's own breed standard warns that Akitas 'may be intolerant of other dogs, particularly of the same sex' — that's not a rare temperament quirk,…
Alaskan Malamute
This is not a bigger husky you can keep quiet in an apartment: Malamutes are powerful, determined escape artists with a strong prey drive toward cats…
American Staffordshire Terrier
This breed carries some of the most restrictive breed-specific legislation of any dog worldwide — outright bans or ownership conditions exist in…
Australian Cattle Dog
This dog was bred to nip the heels of running cattle all day, and a bored, under-exercised Cattle Dog will redirect that instinct onto joggers,…
Australian Shepherd
Aussies were bred to work livestock all day and genuinely need a job — hours of real exercise and mental work, every day, for their whole life — and…
Basset Hound
Those long ears and low-slung body are not just a look, they are a direct cause of the breed's biggest health problems, and Basset Hounds have one of…
Beagle
A Beagle's nose runs the dog, not the owner — bred to follow a scent trail for miles regardless of what the handler wants, so unreliable off-leash…
Belgian Malinois
This is a police- and military-grade working dog with drive most pet homes cannot use up, and it is one of the most common breeds surrendered to…
Bernese Mountain Dog
More than half of Bernese Mountain Dogs die of cancer, and a published Swiss study found median survival of only around eight years, so you are…
Bichon Frise
Marketed as 'hypoallergenic' and easy, but that curly coat needs professional grooming roughly every four weeks for the dog's entire life or it mats…
Bloodhound
This dog's nose overrides its recall almost every time — once a Bloodhound picks up a scent trail it will follow it regardless of traffic, distance,…
Border Collie
Border Collies are widely considered the most intelligent dog breed, but a Border Collie stuck in an apartment without a real job does not relax, it…
Border Terrier
Border Terriers were bred to chase foxes into their dens and dig them out, and that instinct is fully intact — this is a genuine escape-artist digger…
Boston Terrier
Boston Terriers are brachycephalic too, just milder than a Pug, so expect real breathing limits in heat and a jaw shape so narrow that most litters…
Boxer
Boxers have a breed-specific heart disease — arrhythmogenic right ventricular cardiomyopathy, informally called 'Boxer cardiomyopathy' — that can…
Brittany
Brittanys are working bird dogs before they are family pets, and a Brittany that does not get to run or hunt daily becomes a genuinely difficult,…
Bullmastiff
A peer-reviewed veterinary study of Bullmastiffs found a median lifespan of just 8.5 years, with cancer responsible for well over a quarter of all…
Cane Corso
This is a serious guardian breed bred for bite work, not a family pet that happens to be big — Cane Corsos need early, extensive socialization and an…
Cavalier King Charles Spaniel
Heart disease isn't a risk for Cavaliers so much as a near-certainty — about half develop a heart murmur from mitral valve disease by age 5, and…
Chihuahua
Chihuahuas are genuinely fragile, with thin, easily broken leg bones and, in some dogs, a soft spot in the skull that can persist into adulthood, and…
Chow Chow
Chow Chows appear on around 95% of home-insurance breed-restriction lists — in the same tier as pit bulls and Rottweilers — because the breed's…
Cocker Spaniel
Those glorious long ears trap moisture and wax against the skull, so recurring ear infections are close to a lifetime feature of owning a Cocker…
Dachshund
That long back and short legs aren't just a cute silhouette — they're a genuine spinal deformity (chondrodystrophy) that gives Dachshunds one of the…
Dalmatian
Close to 3 in 10 Dalmatians are born with measurable hearing loss in one or both ears, and every single Dalmatian — not just the unlucky ones — has…
Doberman Pinscher
A widely cited European study found that 58% of screened Dobermans had dilated cardiomyopathy, a heart-muscle disease that can cause sudden death…
English Bulldog
Most Bulldogs can no longer mate or whelp without human help — the vast majority of litters are delivered by planned C-section because puppy heads…
English Springer Spaniel
This is a gundog built to work all day in the field, and without serious daily exercise and a job to do, that friendly energy turns into a bored,…
French Bulldog
Most French Bulldogs cannot breathe, cool themselves, or give birth the way a normal dog can — the flat face that defines the breed causes lifelong…
German Shepherd
This is a working police/military breed sold as a family pet, and hip and elbow dysplasia are common enough that breeding-stock screening is standard…
German Shorthaired Pointer
This is an all-day hunting athlete, not a jogging companion — a GSP that only gets a 20-minute walk instead of serious daily exercise and a job to do…
Golden Retriever
Golden Retrievers have one of the highest lifetime cancer rates of any dog breed — a landmark breed-club health survey found roughly six in ten died…
Great Dane
A dog this size usually only gets about 7 to 10 years with you, and its deep chest puts it at real risk of sudden, fatal stomach bloat (GDV) that…
Great Pyrenees
Bred to guard livestock alone through the night, a Great Pyrenees will bark for hours at anything that moves after dark — that's the working trait…
Greyhound
Greyhounds process common anesthetic and sedative drugs very differently from most breeds because of their low body fat and liver enzyme profile, and…
Havanese
Havanese are a genuinely sturdy, healthy toy breed by small-dog standards, but the silky coat is a real daily-brushing job, and this breed bonds so…
Irish Setter
This is a bird-hunting gundog bred for all-day stamina in the field, and its glamorous red coat and friendly good looks lead a lot of buyers to…
Italian Greyhound
Beneath the elegant looks this is a genuinely fragile dog — thin skin, minimal body fat, and slight bone structure mean Italian Greyhounds can…
Jack Russell Terrier
Jack Russells are working hunting terriers bred to chase prey underground, and breed sources are blunt that this drive cannot be trained out — a JRT…
Labrador Retriever
The 'always hungry' Labrador stereotype is partly genetic, not just bad training — about a quarter of the breed carries a gene variant that leaves…
Lhasa Apso
Lhasa Apsos were bred as indoor watchdogs for Tibetan monasteries, not laid-back lapdogs, and breed sources are direct that they have low tolerance…
Maltese
That famous pure-white coat sits on a genuinely fragile toy dog prone to a congenital heart defect, dental disease serious enough to affect other…
Mastiff
A Mastiff's life is short even by giant-breed standards, commonly well under a decade, and that same huge frame carries a serious lifetime risk of…
Miniature Pinscher
Despite the nickname 'King of Toys' and a look that leads many buyers to assume it's a scaled-down Doberman Pinscher, genetic and historical evidence…
Miniature Schnauzer
Miniature Schnauzers are unusually prone to forming bladder stones and to pancreatitis, and both are directly linked to diet and body fat — meaning…
Newfoundland
'Gentle giant' does not mean 'healthy giant': UK breed health data puts this breed's median lifespan at around 9-10 years, and the same data shows a…
Old English Sheepdog
The 'shaggy dog' coat everyone falls for needs several hours of hands-on brushing every week for the dog's entire life — skip it for even a couple of…
Papillon
Papillons are genuinely physically fragile — a toddler's rough handling, an accidental step, or a jump off the couch can cause a serious injury or…
Pembroke Welsh Corgi
That long back on short legs is the same chondrodystrophic build that gives Dachshunds their disc-disease problem, and Corgis gain weight very easily…
Pomeranian
Under that huge coat is a genuinely fragile three-to-seven-pound dog with a real risk of a collapsing windpipe, a slipping kneecap, and dental…
Poodle (Standard)
'Low-shedding' gets marketed as 'low-maintenance' but the two aren't the same thing — a Poodle's coat mats quickly and needs professional clipping…
Portuguese Water Dog
The low-shedding coat that makes this breed popular with allergy-conscious families comes out of a working gene pool with an unusually high published…
Pug
Pugs cannot breathe like a normal dog, and in the largest UK vet-record study of the breed they were found about 54 times more likely to be diagnosed…
Rat Terrier
Rat Terriers were bred as working vermin-hunters and keep a genuinely high prey drive and farm-dog energy level in a body small enough to look like a…
Rhodesian Ridgeback
The 'ridge' that defines this breed's whole identity is genetically linked to dermoid sinus, a birth-defect tube of skin tissue that can run from the…
Rottweiler
Rottweilers carry one of the highest bone-cancer risks of any breed — a UK veterinary study found them roughly 27 times more likely to develop…
Rough Collie
Most Collie owners have never heard of MDR1: the breed's own health foundation estimates that 55-70% of Collies carry this gene mutation, which means…
Saint Bernard
A dog this size shouldn't be dying at 8 to 10 years old, but that's the typical lifespan for a Saint Bernard — add in constant drooling, real bloat…
Samoyed
That famous 'Sammy smile' comes with real costs sellers rarely mention: this breed's odds of developing diabetes are roughly 30 times higher than the…
Scottish Terrier
Scotties carry one of the best-documented cancer risks of any breed — a Purdue University study found them roughly 20 times more likely than other…
Shetland Sheepdog
Shelties are wired to herd and bark at anything that moves, including running kids, cyclists, and the doorbell, and that is the breed working as…
Shiba Inu
Shiba Inus are marketed online as 'cat-like' and low-maintenance because of their small size, but this is a primitive hunting breed with real…
Shih Tzu
That flat, 'cute' face means a genuinely narrowed airway and shallow eye sockets, so breathing trouble in heat and easily injured, bulging eyes are…
Siberian Husky
Huskies are bred to run for miles and treat a fenced yard as a fun puzzle to solve, not an instruction to stay, which is exactly why they are so…
Soft Coated Wheaten Terrier
The single low-shedding coat that makes this breed appealing to allergy-conscious families needs brushing most days for life to avoid matting, plus…
Staffordshire Bull Terrier
Despite the breed's own gentle, people-focused temperament and its old nickname 'the nanny dog,' its bull-and-terrier ancestry and blocky build mean…
Standard Schnauzer
Like other wire-coated 'low-shedding' breeds, a Standard Schnauzer is not allergen-free — people with dog allergies react to dander and saliva…
Vizsla
Nicknamed the 'velcro dog,' Vizslas are bred to work closely with a handler all day and genuinely struggle with being left alone, so separation…
Weimaraner
The elegant 'gentleman's gun dog' image hides a breed that is one of the most likely to develop genuine separation anxiety — destructive chewing,…
West Highland White Terrier
This breed carries roughly a one-in-four chance of developing lifelong itchy skin disease — about double the risk of the average dog — and it's also…
Whippet
A Whippet's skin is almost paper-thin with almost no fat or coat to protect it, so ordinary scrapes, thorny brush, or roughhousing that wouldn't mark…
Yorkshire Terrier
Their tiny size is itself a health liability, not just a look — Yorkies are prone to airway collapse, liver shunts and severe dental disease largely…
No breed by that name yet.
