When choosing a dog, most people focus on cuteness, personality, and size—but veterinarians look through a different lens. Some breeds come with significant health or behavioral challenges that can lead to heartache and costly vet bills. Here are 10 breeds many vets caution against owning, especially for first-time or unprepared dog owners.
English Bulldog
English Bulldogs are beloved for their squishy faces and laid-back attitudes, but vets often view them as walking medical emergencies. Their flat faces can lead to chronic breathing issues, and their stocky bodies are prone to joint and spinal problems. Skin infections, eye issues, and heat intolerance are common, making them one of the highest-maintenance breeds to care for.
Cavalier King Charles Spaniel
This sweet and gentle breed is a favorite among families, but it comes with a heartbreaking predisposition to mitral valve disease, a serious heart condition. Many Cavaliers develop symptoms as early as age five. Vets also see frequent issues with hip dysplasia, eye conditions, and syringomyelia—a painful neurological disorder that affects the spine.
German Shepherd
German Shepherds are loyal, intelligent, and versatile—but their health problems can be daunting. Hip and elbow dysplasia are widespread in the breed, along with degenerative myelopathy, a progressive spinal condition that leads to paralysis. Their high intelligence also means they require constant mental stimulation. Without it, they can become anxious or destructive.
Shar Pei
Known for their adorable wrinkles, Shar Peis are prone to numerous health complications. Vets regularly see skin infections in the folds, eye problems like entropion (where the eyelids roll inward), and recurrent ear infections. Shar Pei Fever, a hereditary condition causing swelling and high fever, is another concern. Many require ongoing medications and surgeries to manage their issues.
Great Dane
Their massive size makes Great Danes gentle giants, but that size also shortens their lifespan and increases health risks. Vets often caution about bloat (gastric dilatation-volvulus), a life-threatening condition that can kill a Dane within hours if not treated. Joint issues, heart disease, and cancer are also prevalent, with many Danes living only 6 to 8 years.
Dachshund
Dachshunds are energetic and fun, but their long backs and short legs make them prone to intervertebral disc disease (IVDD), a condition that can cause sudden paralysis. Vets warn that even simple activities like jumping off the couch can cause serious injury. Owners must be vigilant about managing their dog’s weight and movement.
Boxer
Boxers are affectionate and playful but face a variety of medical red flags. Vets frequently diagnose them with heart conditions such as cardiomyopathy and subaortic stenosis. They’re also highly prone to cancers, especially lymphoma and mast cell tumors. Their energetic nature can mask health issues until they become severe.
Siberian Husky
Siberian Huskies are beautiful and independent—but they are not for everyone. Vets warn that many end up in shelters due to behavioral mismatches with owners. Huskies require extensive exercise and secure fencing, as they are notorious escape artists. They are also prone to autoimmune diseases and eye problems such as cataracts and progressive retinal atrophy.
Chihuahua
While their small size makes them appealing, Chihuahuas are among the most fragile breeds. Vets see frequent injuries due to rough handling or accidental falls. They’re also prone to dental disease, luxating patellas, and hypoglycemia. Some exhibit intense anxiety or fear-based aggression, making them better suited to experienced dog owners.
Cocker Spaniel
Cocker Spaniels have soft eyes and sweet personalities, but vets often treat them for chronic ear infections, skin allergies, and eye conditions like glaucoma. Their long, floppy ears create a warm, moist environment that bacteria love. Behaviorally, some Cockers can also show signs of unpredictability or aggression if not properly socialized.
