These beloved dog breeds come with hidden issues that every owner should know about.
Bringing home a dog is an exciting experience, but most new owners have no idea what they’re getting into when it comes to breed-specific health problems. People fall in love with cute faces, wagging tails, and playful personalities, only to discover later that their furry friend comes with a long list of medical concerns. Some are manageable, while others can lead to heartache, endless vet bills, and even shortened lifespans.
Breeders and pet stores rarely disclose the full extent of these issues, and even veterinarians might not spell it all out unless you ask. Knowing what you’re signing up for is crucial, especially with breeds prone to major health complications. From breathing problems to devastating diseases, here are ten popular breeds with serious issues that often go unmentioned.
1. English Bulldogs struggle with breathing and heat sensitivity more than most owners realize.
No one can deny how adorable English Bulldogs are, but their signature wrinkled face and short snout come at a price. Breathing problems plague this breed due to brachycephalic syndrome, which makes even mild exercise a struggle. Many Bulldogs snore like chainsaws, wheeze constantly, and overheat easily, making them extremely sensitive to warm weather.
According to Oliver Animal Hospital, English Bulldogs often require surgery to correct airway blockages just to improve their ability to breathe. On top of that, their heavy-set bodies make them prone to joint issues, and their deep facial wrinkles can trap moisture and bacteria, leading to chronic skin infections. Owning one means constant vet visits, careful monitoring, and a high tolerance for snorting noises.
2. Golden Retrievers may be loving, but their cancer rates are alarmingly high.
Few breeds are as universally adored as Golden Retrievers, but their reputation for being perfect family dogs hides a sad reality—many don’t live as long as they should. Goldens have one of the highest cancer rates of any dog breed, with hemangiosarcoma and lymphoma being the biggest culprits.
As noted by WebMD Pets, nearly 60% of Golden Retrievers will develop cancer at some point in their lives. The breed’s genetic predisposition to these diseases has led to ongoing research to figure out why they’re so vulnerable. Despite their cheerful and affectionate nature, owners should prepare for the possibility of expensive treatments and difficult medical decisions down the road.
3. German Shepherds may look strong, but their joints and spine tell a different story.
With their intelligence and work ethic, German Shepherds are often chosen for police and military roles. However, their sturdy appearance hides a painful truth—many suffer from hip and elbow dysplasia, which can cause severe arthritis and mobility issues. As they age, walking can become painful, and some struggle to even stand.
PetMD also warns about degenerative myelopathy, a devastating spinal disease that gradually paralyzes the back legs. Treatment options are limited, and there is no cure. While Shepherds are fiercely loyal and incredibly smart, potential owners need to be prepared for the possibility of mobility issues and the cost of joint-supportive care.
4. Cavalier King Charles Spaniels are heartbreakingly prone to heart disease.
It’s impossible to resist the big, soulful eyes of a Cavalier King Charles Spaniel, but behind that sweet expression lies a breed with serious health concerns. Mitral valve disease (MVD) is a common condition in Cavaliers, affecting their hearts at an alarmingly high rate. Many develop this disease by middle age, and without treatment, it can lead to heart failure.
Beyond Pets also points out that Cavaliers frequently suffer from syringomyelia (SM), a painful neurological condition that causes intense discomfort. Symptoms include excessive scratching, sensitivity to touch, and difficulty moving. While they are affectionate, loving companions, their potential medical issues can be emotionally and financially exhausting for owners.
5. Cocker Spaniels come with more ear infections than most people expect.
Floppy-eared dogs are undeniably cute, but those long ears come with a downside—Cocker Spaniels are notorious for chronic ear infections. Their ears trap moisture and debris, creating the perfect breeding ground for bacteria and yeast. Owners often find themselves constantly cleaning ears and making vet trips for antibiotics.
Beyond ear issues, Cockers are also prone to eye problems like progressive retinal atrophy (PRA), which leads to gradual blindness. Their affectionate nature makes them wonderful pets, but anyone considering this breed should be ready for regular grooming and plenty of ear cleanings.
6. Labrador Retrievers love food so much that obesity is a real problem.
Labs are known for their boundless energy, but they’re also infamous for their love of food. Many will eat anything and everything, which makes them one of the most obesity-prone breeds. Excess weight puts extra stress on their joints, increasing the risk of hip and elbow dysplasia.
While they remain one of the most popular family dogs, owners need to resist the urge to overfeed and provide plenty of exercise. A chunky Lab might look cute, but the extra pounds can lead to serious health issues later in life.
7. Boxers have a shockingly high risk of heart disease.
Few breeds are as goofy and energetic as Boxers, but their playful personalities hide a serious problem—many suffer from a condition called Boxer cardiomyopathy. This genetic disease affects the heart’s electrical system, leading to irregular heartbeats, fainting spells, and in severe cases, sudden death.
Regular heart screenings are essential for Boxers to catch early signs of trouble. Despite their health concerns, they remain beloved for their affectionate and silly nature. Owners just need to be aware that this breed may require lifelong heart monitoring.
8. Rottweilers are prone to bone cancer and joint problems.
Rottweilers exude strength and confidence, but their large size puts them at risk for serious health issues. Osteosarcoma, a highly aggressive bone cancer, is unfortunately common in this breed. Many Rottweilers also develop hip and elbow dysplasia, leading to mobility issues as they age.
While they are loving and loyal dogs, their potential for costly medical issues makes them a serious commitment. Proper weight management and joint supplements can help, but their genetic predisposition to these conditions is something every owner should consider.
9. Poodles need constant grooming and struggle with anxiety.
Poodles are often praised for being intelligent and hypoallergenic, but they come with their own set of challenges. Their curly coats require professional grooming every few weeks to prevent painful matting, which can lead to skin infections.
Beyond their grooming needs, Poodles are also known for being emotionally sensitive. Without proper socialization and stimulation, they can become anxious and develop neurotic behaviors. While they make great companions, they need both mental engagement and consistent care to thrive.
10. Yorkshire Terriers are tiny but surprisingly stubborn and yappy.
Yorkies may be small, but they have big personalities—and even bigger opinions. Many owners struggle with house-training because this breed can be notoriously stubborn. Excessive barking is another common issue, especially if they aren’t properly trained.
Despite these challenges, Yorkies remain one of the most popular toy breeds. With the right training and patience, they can be loving and loyal pets, but they aren’t the low-maintenance lapdogs many people expect.
Understanding a breed’s hidden health risks is essential before bringing a dog into your home. Every dog has its quirks and challenges, but being prepared can make all the difference in providing a happy and healthy life for your furry companion.
