Bernese Mountain Dog Health Issues: 9 Problems Every Owner Should Know
If you are lucky enough to share your life with a Bernese Mountain Dog, you already know they are basically 100-pound lap dogs in giant, fluffy, tri-colored suits. They will lean heavily against your legs, look up at you with those soulful, pleading brown eyes, and completely steal your heart before you even realize what happened.
But loving a Berner comes with a heavy emotional caveat. While they are renowned for their gentle, family-friendly temperaments, they also have heartbreakingly short life expectancies. The average Bernese Mountain Dog lifespan hovers around just 7 to 10 years. In my years of raising and working alongside large breed dogs, I’ve held the paws of many pet parents who were completely blindsided by sudden medical emergencies or chronic illnesses.
Knowledge is power. If you are caring for a Bernese Mountain Dog, understanding Bernese Mountain Dog health issues isn't just about preparing yourself emotionally—it’s about catching symptoms early, making lifestyle adjustments, and potentially giving your best friend more healthy years by your side.
Let's walk through the nine most common health problems every Berner owner needs to have on their radar.

1. Cancer: The Heartbreaking Reality
Let’s get the hardest topic out of the way first. When we talk about Berner health risks, cancer is the giant elephant in the room. Some veterinary studies suggest that up to 50% to 67% of Bernese Mountain Dogs will face a cancer diagnosis in their lifetime.
The most devastating and prevalent type in this specific breed is Histiocytic Sarcoma. This aggressive cancer affects the histiocytes, which are a type of white blood cell that normally help the immune system fight off pathogens. According to the Morris Animal Foundation, this cancer can be localized to a joint or skin, or disseminated throughout multiple organs, spreading at an alarming rate.
Other cancers frequently seen in the breed include lymphoma, mast cell tumors, and osteosarcoma (bone cancer).
Personal Observation: I always tell new Berner parents to make "lump checks" a part of their weekly grooming routine. Because these dogs have incredibly thick double coats, tumors can easily hide underneath all that fluff.
Symptoms to watch for:
- Unexplained weight loss or severe lethargy
- Sudden limping or swelling in a joint
- Chronic coughing or difficulty breathing
- Lumps under the skin that change in size
2. Gastric Dilatation-Volvulus (Bloat): A True Emergency
Like many large, deep-chested breeds, Bernese Mountain Dogs are at a very high risk for Gastric Dilatation-Volvulus (GDV), universally known as "bloat".
Bloat happens when the stomach fills rapidly with gas, food, or fluid, and then twists on its own axis. This twisting cuts off the blood supply to the stomach and spleen, sending the dog into systemic shock in a matter of hours, or even minutes. The American College of Veterinary Surgeons warns that GDV is always a critical, life-threatening emergency requiring immediate surgical intervention.
Pro-Tip: Never let your Berner chug massive amounts of water right after an intense play session, and avoid heavy exercise for at least an hour before and two hours after meals. I highly recommend using a slow-feeder bowl to prevent them from gulping air while they eat. Many vets also recommend a preventative surgery called a prophylactic gastropexy (tacking the stomach to the abdominal wall) when your dog goes in to be spayed or neutered.
Signs of Bloat:
- Pacing, restlessness, and an inability to get comfortable
- Unproductive retching (trying to vomit but nothing comes up)
- A swollen, tight, drum-like abdomen
- Pale gums and heavy panting
3. Hip Dysplasia: The Heavy Burden on Hind Legs
When you combine rapid puppy growth with a heavy adult frame, your dog's joints take a massive beating. Bernese Mountain Dog hip dysplasia is an inherited orthopedic condition where the ball and socket of the hip joint do not fit together smoothly. Instead of gliding, the joint grinds, leading to painful osteoarthritis, bone spurs, and eventually lameness.
According to VCA Animal Hospitals, this uniform growth failure during puppyhood means laxity (looseness) develops in the joint.
You might notice your Berner struggling to push themselves up off the hardwood floor or doing an odd "bunny hop" with their back legs when they run. Managing Bernese joint problems usually involves keeping your dog at a strictly lean weight. Every extra pound of fat is an agonizing burden on a dysplastic hip. Joint supplements containing high-quality glucosamine, chondroitin, and Omega-3 fatty acids are a must.
4. Elbow Dysplasia: Forelimb Struggles
Much like the hips, the elbows of a Bernese Mountain Dog are highly susceptible to developmental abnormalities. Elbow dysplasia is an umbrella term covering several specific growth defects in the forelimb joints.
Because Berners carry the majority of their heavy body weight on their front legs, elbow dysplasia can severely cripple their mobility. You’ll usually see symptoms start when the dog is still young—sometimes between 4 to 10 months of age. They might develop a noticeable front-leg limp that gets worse after exercise.
Responsible breeders will always screen their breeding dogs through the Orthopedic Foundation for Animals (OFA) or the PennHIP method to ensure they aren't passing these faulty joint genes to the next generation. If you're bringing home a puppy, always ask to see the parents' joint clearances!
5. Progressive Retinal Atrophy (PRA): Fading Vision
Imagine your dog suddenly becoming afraid of the dark, refusing to go outside at night, or bumping into the coffee table. These are classic signs of Progressive Retinal Atrophy (PRA).
PRA is an inherited eye condition where the retina slowly degenerates over time. It typically starts with night blindness and tragically progresses to total blindness. While it is a painless condition, losing their sight can be incredibly disorienting and anxiety-inducing for a dog.
Currently, there is no cure for PRA. However, dogs are incredibly resilient and adaptive animals. If your Berner loses their vision, they will rely heavily on their acute sense of smell and hearing. You can help them navigate life by keeping furniture in the same place and using scented markers around stairs and doorways.
6. Von Willebrand’s Disease (vWD): Bleeding Risks
Von Willebrand’s Disease is the most common inherited bleeding disorder in dogs, and Bernese Mountain Dogs are genetically predisposed to it.
Dogs with vWD lack a specific protein in their blood (von Willebrand factor) that helps platelets clump together to form clots. As a result, even a minor scrape, a broken toenail, or a routine surgery can result in excessive, dangerous bleeding.
Most owners don't realize their dog has this condition until they go in for their spay/neuter surgery and the vet struggles to stop the bleeding. This is exactly why genetic testing is so vital for large breed dog health. A simple DNA test can tell you if your dog carries the gene for vWD. If they do, your vet can take special precautions before any surgical procedure.
7. Degenerative Myelopathy (DM): Neurological Decline
Degenerative Myelopathy is a devastating, progressive disease of the spinal cord that is sadly seen in the Berner breed. You can think of it as the canine equivalent of ALS (Lou Gehrig’s Disease) in humans.
It usually strikes older dogs. The protective sheath surrounding the spinal cord begins to degenerate, interrupting the signals between the brain and the hind legs. It starts subtly. You might hear your dog's back nails scraping against the pavement during a walk, or notice their hind legs slightly swaying when they stand still.
Over the course of several months to a year, the weakness progresses until the dog is completely paralyzed in the rear. Because it is a painless disease, many owners opt to get their Berners fitted for a dog wheelchair, which can grant them months of continued mobility and joy.
8. Mast Cell Tumors: Lumps and Bumps
While we touched on the aggressive Histiocytic Sarcoma earlier, it’s worth specifically calling out Mast Cell Tumors (MCTs). Mast cells are a type of white blood cell involved in allergic reactions. When these cells become cancerous, they form tumors, most commonly on or just under the skin.
What makes MCTs tricky is that they are the great pretenders of the dog world. An MCT can look like a harmless fatty lipoma, a bug bite, a wart, or an ulcerated red sore. There is no way to know what a lump is just by looking at it or feeling it.
If you find a new lump on your Bernese Mountain Dog, do not wait to see if it goes away. Take them to the vet immediately for a fine needle aspirate. The vet will use a tiny needle to pull cells from the lump and look at them under a microscope. Catching a malignant mast cell tumor early and surgically removing it with wide margins can be completely curative.
9. Skin Allergies and Hot Spots: The Itchy Truth
If you’ve ever owned a double-coated dog, you know they are magnets for moisture, dirt, and allergens. Berners are highly susceptible to environmental allergies (like pollen, grass, and dust mites) and food allergies.
When a Berner is allergic to something, they rarely get the sniffles. Instead, their skin reacts. They will chew their paws relentlessly, scratch their ears until they get an ear infection, or lick their flanks raw.
Because their coat is so thick, moisture can get trapped against the skin after a bath or a swim. This creates the perfect breeding ground for bacteria, resulting in "hot spots"—angry, red, oozing, and intensely painful skin infections that seemingly appear overnight.
Pro-Tip: Invest in a high-velocity dog dryer. Whenever your Berner gets wet, blow-dry their coat all the way down to the skin to prevent moisture from becoming trapped.
Essential Health Screenings for Berners
To give you a quick reference guide, here is a breakdown of the typical health screenings and conditions you should monitor alongside your veterinarian.
Frequently Asked Questions (FAQ)
What is the average Bernese Mountain Dog lifespan? Sadly, the lifespan of a Bernese Mountain Dog is much shorter than smaller breeds. They typically live between 7 to 10 years. Their shorter lifespan is primarily due to their large size and high genetic predisposition to aggressive cancers like Histiocytic Sarcoma.
How can I prevent Bernese Mountain Dog bloat? While you cannot 100% guarantee a dog won't bloat, you can drastically reduce the risks. Feed your dog two to three smaller meals a day rather than one massive meal. Use a slow-feeder bowl to prevent gulping, avoid heavy exercise around meal times, and talk to your vet about a preventative stomach-tacking surgery (gastropexy).
Are Bernese Mountain Dogs expensive to care for medically? Yes, quite frankly, they are. Because they are a giant breed, everything costs more—from the volume of anesthesia required for surgeries, to the dosage size of antibiotics and heartworm preventatives. Caring for a Bernese Mountain Dog almost necessitates getting high-quality pet insurance the day you bring your puppy home, long before any pre-existing conditions develop.
How do I know if my Berner has hip dysplasia? Look for subtle behavioral changes. They might hesitate to jump into the car, struggle to climb the stairs, or have difficulty rising after a long nap. You may also notice a "bunny-hopping" gait where they use both back legs together to run. If you notice these signs, schedule an x-ray with your vet.
Conclusion & Sources
Loving a Bernese Mountain Dog is an incredibly rewarding experience. Their loyalty, goofy antics, and profound affection make every single shed hair and medical bill worth it. However, burying your head in the sand about Bernese Mountain Dog common diseases does your dog a massive disservice.
By familiarizing yourself with these nine health conditions, feeding a high-quality diet, maintaining a lean body weight, and prioritizing routine veterinary care, you are actively giving your Berner the best chance at a longer, happier life. Cherish every moment, take entirely too many photos, and never hesitate to call your vet if something feels "off." You know your dog best!
