Breed specific health concerns: what to know before and after you own one
Why selective breeding concentrated certain inherited health risks in specific dog and cat breeds, what those risks are, and how testing and proactive care lower them.

Breed specific health concerns are inherited conditions that show up more often in certain dog or cat breeds because of the genes concentrated by generations of selective breeding for a particular look or temperament. A Bulldog's flattened face, prized for decades in the breed standard, comes packaged with a real risk of breathing difficulty. A Maine Coon's size and coat come with a higher risk of a specific heart condition. None of this means a given breed is a bad choice, but it does mean a buyer or new owner benefits from knowing exactly what to watch for.
This guide covers why these risks exist, which conditions show up in which breeds, what genetic testing and responsible breeding can catch before a puppy or kitten is even born, and what proactive owners can do once the animal is already home. If you are choosing a breeder, our genetic screening for breeders guide covers the testing side from the breeder's perspective.
Why selective breeding created these risks in the first place
Breed standards reward specific physical traits: a certain coat, a certain body shape, a certain size. Selecting hard for one trait over many generations tends to pull along whatever genes sit near it, including ones that cause health problems, and it shrinks the pool of genetic variation available to counteract them. A Bulldog's short muzzle is a direct product of selecting for a flat face; the airway problems that come with it are a side effect nobody was breeding for on purpose, but the two are genetically linked closely enough that you cannot easily have one trait without some version of the other risk.
The same dynamic plays out across both dogs and cats. Persian cats prized for long coats and flat faces face higher rates of eye and respiratory issues for the same structural reason Bulldogs do. Dachshunds bred for their elongated body and short legs carry a structurally higher risk of spinal disc disease, because that same elongation puts more mechanical stress on the discs between vertebrae. None of these are certainties for any individual animal, but they are real, well documented tendencies at the breed level.
| Breed | Common health risk | Why it happens |
|---|---|---|
| Bulldog | Breathing difficulty from a narrowed airway | Selected for a flat, short muzzle |
| Labrador Retriever | Hip and elbow dysplasia | Joint conformation combined with rapid puppy growth |
| German Shepherd | Degenerative myelopathy | A specific gene mutation concentrated in the breed |
| Dachshund | Intervertebral disc disease | An elongated spine relative to leg length |
| Maine Coon | Hypertrophic cardiomyopathy | A heart muscle gene mutation common in the breed |
| Siamese cat | Progressive retinal atrophy | An inherited retinal gene variant |
What genetic testing catches before a litter is even born
Most of the conditions in the table above can be screened for, at least in part, before an animal is ever bred. Hip and elbow evaluations use x-rays and a standardized scoring system to flag dogs likely to pass on joint problems. Cardiac exams, sometimes paired with a DNA test for the specific mutation involved, can identify Maine Coons carrying the hypertrophic cardiomyopathy gene before symptoms appear. Eye exams from a veterinary ophthalmologist can catch early signs of retinal disease in breeds like the Siamese.
None of this eliminates risk entirely, and closely related pairings raise the odds regardless of individual test results, which is why testing and diverse pedigrees work together rather than as substitutes for each other. Our inbreeding in purebred dog breeding piece covers how relatedness itself compounds these risks beyond what a single generation's testing can catch. A breeder who can produce recent, breed appropriate test results for both parents has done meaningfully more to reduce your future vet bills than one who cannot.
Proactive care once you already own an at-risk breed
A breed prone to a certain condition is not the same as a breed guaranteed to develop it, and day to day care changes the odds. Routine veterinary visits matter more for these breeds specifically, not less, since early detection of joint, heart, or eye disease usually means more treatment options and a better outcome. Bring up your breed's known risks directly with your vet rather than waiting for a symptom to appear, so screening happens on a schedule rather than only after something goes wrong.
Weight management deserves particular attention. Extra weight worsens hip dysplasia, back problems, and heart conditions simultaneously, which makes it one of the highest leverage things an owner controls directly. Exercise should match the breed's actual physical limits: flat faced breeds need shorter, cooler outings, while large breeds prone to joint disease often do better with low impact activity like swimming instead of repeated high impact runs or jumping. Diet can help too. Joint support supplements are commonly used for breeds prone to spinal or joint issues, and heart healthy formulations exist for breeds like the Maine Coon, though any specific dietary change is worth confirming with your vet first rather than guessing.
Retiring a few persistent myths
The idea that only purebred animals face hereditary health issues is not accurate. Mixed breed animals inherit genes from their parents just like purebreds do, and if both parents happen to share a risk factor, whether from a shared breed in their ancestry or independent carriers of the same mutation, the offspring can inherit it too. Being mixed breed lowers the odds of certain concentrated single gene conditions somewhat, since the gene pool involved is usually broader, but it does not remove genetic risk.
It is also not true that every animal of an at-risk breed will develop the associated condition. These are higher probabilities at the population level, not individual guarantees. A Bulldog can live a long, comfortable life with a mild version of airway narrowing, just as a Labrador can go its whole life with healthy hips despite the breed average risk. And genetic testing, while useful, is not a guarantee of a disease free animal either. It lowers the odds for the specific conditions tested, but general health, injury risk, and conditions with no known genetic marker yet all remain in play. Routine care through the animal's life, not a one time test result, is what actually manages the risk over time. Owners of senior pets in particular should keep an eye on how these breed tendencies evolve with age; our senior pet preventive care guide and our guide to vet checkup schedules cover what that ongoing monitoring should look like.
Are breed specific health issues the same as genetic disorders?
They overlap but are not identical. A breed specific health concern is any condition that shows up more often in a particular breed, which is usually genetic but can also involve structural factors tied to conformation, like a short muzzle affecting airflow. A genetic disorder specifically traces to an identifiable gene or set of genes, which is only sometimes the full explanation for a breed tendency.
Can genetic testing eliminate breed specific health risks entirely?
No. Testing identifies carriers of known, specific inherited conditions and helps breeders avoid pairing two carriers of the same one, which lowers risk considerably. It cannot catch conditions without an identified genetic marker, and it does not remove risks tied to structural conformation, like airway shape in flat faced breeds, which testing alone cannot fix.
Should I avoid buying a breed known for health problems?
Not necessarily. Focus instead on the individual breeder's practices: whether they test for the conditions relevant to that breed, whether they can show you results for both parents, and whether they avoid breeding animals with known conditions. A well managed breeding program in a breed with known risks is often a safer choice than an untested pairing in a breed with fewer known issues.
What is hip dysplasia and which breeds are most affected?
Hip dysplasia is a malformation of the hip joint that causes pain, reduced mobility, and arthritis over time. Larger breeds are affected most often, including Labrador Retrievers, German Shepherds, and Golden Retrievers, largely because of the combination of joint conformation and rapid growth during puppyhood, though any breed or mixed breed dog can develop it.
How often should an at-risk breed see the vet compared to other pets?
Most healthy adult dogs and cats do well with an annual exam, but breeds with known hereditary risks often benefit from more frequent, targeted checks, such as yearly cardiac screening for a Maine Coon or periodic hip and joint evaluation for a large breed dog. Ask your vet to set a schedule based on your specific breed's known risk profile rather than a generic yearly visit.
