Dogs are wonderful companions, but it’s important to recognize that certain breeds are more prone to serious health problems than others. These conditions can lead to costly vet bills, constant care, and heartbreaking moments for owners when their beloved pets suffer.
In particular, other dog breeds with brachycephalic (flat-faced) features, such as Bulldogs, Pugs, and French Bulldogs, are adored by many for their unique looks but are also at high risk of breathing difficulties, eye problems, and complications during birth. Critics argue that selective breeding for exaggerated traits has come at the expense of the dogs’ well-being.
Animal welfare groups, including PETA, have called for reforms to breed standards to prioritize health over appearance. Hence, this matter is finally getting the importance it needs.
Beyond brachycephalic dogs, other breeds with long histories of inbreeding or extreme body structures also face inherited disorders that shorten lifespans and reduce quality of life.
With this in mind, let’s take a closer look at dog breeds known for significant health challenges, so you can make an informed choice before bringing one home.
Unhealthy Dog Breeds You’ll Regret Owning
1. English Bulldog
English Bulldogs are loved for their sweet nature and charming looks, but sadly, they are also one of the most unhealthy breeds. Their short, flat faces may look endearing, but they cause serious breathing difficulties, loud snoring, and trouble with even mild exercise.
Many bulldogs also struggle to walk comfortably, and some cannot give birth naturally without medical intervention.
This isn’t the fault of the dogs; it’s the result of years of selective breeding for exaggerated features. Unfortunately, those same features have left them vulnerable to a wide range of health problems, including obesity, skin infections, hip dysplasia, spinal deformities, eye conditions, and a serious condition known as brachycephalic obstructive airway syndrome (BOAS).
For many owners, it can be heartbreaking to watch a bulldog they love dearly struggle with daily activities like breathing or walking.
While bulldogs can be affectionate and loyal companions, it’s important to understand the significant health risks they face and the responsibilities that come with caring for them.
2. Pug
Pugs are adored for their big eyes, charming personalities, and playful nature. Sadly, though, these little dogs are also among the breeds that suffer the most from health problems linked to selective breeding.
Purina states that their short, flat faces make them prone to breathing difficulties, loud snoring, and overheating, even after light exercise.
On top of this, their prominent eyes sit in shallow sockets, which puts them at high risk for painful injuries and infections. In some cases, eye problems can become so severe that surgery is required. Many pugs also struggle with skin issues, joint problems, and other conditions throughout their lives.
None of this is the fault of the dogs themselves; they are affectionate, loyal companions who simply want to love and be loved.
But their popularity has come at a cost, and it’s important for potential owners to understand the extra care, medical attention, and financial commitment needed to keep them healthy and comfortable.
3. French Bulldog
It may come as a surprise to see the French Bulldog, America’s most popular dog, on the list of unhealthy breeds. Their playful personalities, comical expressions, and bat-like ears make them irresistible to many dog lovers. But behind the charm lies a long list of serious health concerns.
French Bulldogs are a brachycephalic (flat-faced) breed, which means they are especially prone to breathing difficulties, as Orvis mentions.
Many also suffer from conditions such as cleft palate, eye problems like entropion and painful ulcers, skin infections from their wrinkles, and spinal or digestive issues. Because of their body structure, most Frenchies cannot give birth naturally and require caesarean sections.
Research shows that French Bulldogs are more likely than many other breeds to develop a range of medical problems; one study found they were at risk for 20 common health issues.
On average, they also live shorter lives than non-brachycephalic breeds, with a typical lifespan of around 8.7 years compared to 12 years or more in other dogs.
This doesn’t make them any less loving or devoted as pets, but it does mean they require special care, regular vet visits, and an understanding owner who can meet their unique needs.
4. Cavalier King Charles Spaniel
The Cavalier King Charles Spaniel is adored worldwide for its affectionate personality and sweet, expressive face. Unfortunately, behind their charm lies a serious health concern: many Cavaliers suffer from mitral valve disease, a heart condition that often shortens their lives.
One reason this great dog breed faces so many health challenges is its limited genetic diversity. After World War II, the breed’s population was reduced dramatically, leading to a very narrow gene pool.
This history of inbreeding has increased the risk of inherited disorders, including heart disease, syringomyelia (a painful neurological condition), hip dysplasia, patellar luxation, and certain eye problems.
Because of this, Cavaliers often require careful monitoring, health screenings, and in some cases, ongoing medical care. Responsible breeding programs that prioritize genetic health are essential to improving the future of the breed.
Despite their vulnerabilities, Cavaliers remain deeply loving and loyal companions. For anyone considering this breed, it’s important to be aware of the potential medical challenges, choose reputable breeders who perform health testing, and be prepared for the extra care these dogs may need.
5. Great Dane
Great Danes are often called “gentle giants” for their kind and affectionate nature. They can be wonderful family dogs, especially with children, but owning one is a major commitment.
Their massive size means they eat more than smaller breeds, require plenty of space, and, unfortunately, face a number of serious health concerns.
Veterinarians sometimes refer to Great Danes as the “heartbreak breed” because of their very short lifespan, typically only 7 to 10 years. They are prone to skeletal problems, hip dysplasia, and a variety of heart conditions.
One of the most dangerous health risks is bloat (gastric dilatation-volvulus), which is a leading cause of death in the large dog breed and can become life-threatening within hours.
Other conditions that affect Great Danes include dilated cardiomyopathy, thyroid disorders, and certain eye diseases. Regular veterinary checkups, careful diet management, and awareness of the signs of bloat are essential for owners who want to give their Dane the healthiest and happiest life possible.
Despite these challenges, Great Danes are affectionate, loyal companions who thrive in loving homes with owners prepared for their unique needs.
6. Saint Bernard
Saint Bernards are famous for their history as heroic alpine rescue dogs and are still cherished today for their gentle, affectionate nature. They can make wonderful family companions, but potential owners should know that this giant breed comes with significant health challenges.
Because of their large size, Saint Bernards are prone to hip and elbow dysplasia, back problems, and joint pain. They are also at higher risk for heart disease, digestive issues, and certain cancers, including bone cancer. Sadly, their lifespan is quite short, often only 8 to 10 years, which can be heartbreaking for families.
While not considered a “deformed” breed, Saints still face the consequences of their size and past breeding practices, which leave them vulnerable to health problems and immune-related issues. They are also known for being heavy droolers and require consistent grooming and care.
Despite these challenges, Saint Bernards are loyal, loving, and deeply intuitive dogs who often excel as emotional support companions. For families prepared for the commitment, they can bring a great deal of comfort and affection, but it’s important to go in with realistic expectations about their care and health needs.
7. Dachshund
Dachshunds, affectionately known as “sausage dogs” or “hot dogs,” are beloved for their playful personalities and unique, elongated bodies.
Originally bred in Germany to hunt badgers and burrow underground, their long backs and short legs made them well-suited for the job. Unfortunately, those same features put them at risk for serious health problems today, as per Hill’s Pet US.
Because of their body shape, Dachshunds are highly prone to intervertebral disc disease (IVDD), which can cause severe back pain and, in some cases, paralysis.
They are also susceptible to slipped discs, joint problems, and eye conditions such as progressive retinal atrophy. These issues can greatly affect their mobility and quality of life.
None of this diminishes their affectionate and spirited nature; Dachshunds are loyal, brave, and full of character. But potential owners should be aware that caring for this hunting dog breed often requires extra precautions, such as avoiding activities that strain the back (like jumping off furniture) and maintaining a healthy weight to reduce stress on their spine.
With proper care and attention, Dachshunds can still be wonderful companions, but their unique build comes with responsibilities that every prospective owner should carefully consider.
8. Shar Pei
The Chinese Shar Pei is instantly recognizable for its deeply wrinkled skin and unique appearance. While these wrinkles make them stand out, they also contribute to a number of health problems that can affect this beautiful dog breed throughout its life.
Shar Peis are prone to painful skin conditions, such as infections caused by bacteria and yeast that get trapped in their skin folds. They often suffer from allergies, lip-fold pyoderma, and ear infections due to their narrow ear canals.
In addition, they are at risk for eye problems like entropion (where the eyelids roll inward), hip dysplasia, hypothyroidism, and even digestive issues such as megaesophagus.
Another serious condition associated with the breed is Shar Pei Fever, a hereditary disorder that can cause recurring fevers and swollen joints. In many cases, corrective surgery is needed to address issues like entropion to prevent long-term discomfort and protect their eyesight.
Despite these health challenges, Shar Peis are known for their loyalty, independence, and protective nature. With proper veterinary care, regular grooming, and responsible breeding practices, they can live happy, fulfilling lives. Anyone considering this breed should be aware of the extra attention and medical care they may require.
9. German Shepherd
German Shepherds are one of the most recognizable and admired breeds in the world. Known for their intelligence, loyalty, and working ability, they often serve as police dogs, service dogs, and devoted family protectors. However, their popularity has also come with significant challenges.
German Shepherds are highly active and intelligent, which means they require constant physical exercise and mental stimulation. Without it, they can develop anxiety, frustration, or behavior problems. Unfortunately, many people adopt them without fully understanding how much time and commitment these dogs need to thrive.
On the health side, German Shepherds are prone to several hereditary conditions. These include hip and elbow dysplasia, heart issues, digestive problems like bloat, skin allergies, and eye conditions.
They are also vulnerable to more serious illnesses such as hemangiosarcoma (a type of cancer) and degenerative spinal disorders linked to their sloping backs, which have become exaggerated in some breed lines.
Despite these risks, German Shepherds remain loyal, courageous, and deeply bonded companions when placed in the right homes. For potential owners, it’s important to be prepared for their exercise needs, regular veterinary care, and the responsibility of supporting such an active working breed.
Conclusion
Regrettably we aren’t doing much to break this torturous cycle of unethical inbreeding, selective breeding and uncaring attitudes towards the welfare of animals. Because even though the answer remains in front of us our unhealthy obsession for keeping the lines of purebred dogs is causing more harm than helping.
The medical issues of these poor dogs can be solved or would have never even started in the first place if there was enough genetic diversity among prospective parents of new dogs. Moreover, by shattering the mold and thinking outside of the box. By being more freeing and less stingy about the good looks of these dogs we can possibly save more dogs on this planet.
But a huge step towards the betterment of these loving dogs is necessary and should be taken. Hence, let’s forget the breed standards and accept each pooch on the planet as an individual. Unique and distinct in the matter of its qualities and never judged for how it looks or what does.
Your best bet is to try a mixed breed from a local shelter or rescue more than these esteemed purebred dogs who are wrapped up as perfect pooches by every kennel club but are in truth a disservice to the dog breeds itself.
P.S A few breeds to avoid include poodle, basset hound, corgis, pocket pit bulls or bulldogs, sled dogs like the Siberian husky, golden retrievers and tiny designer breeds like the teacup chihuahuas, Maltese or yorkies.
