3 Common Bernese Mountain Dog Behaviour Problems (And How To Fix Them)

Remember: Your Bernese Mountain Dog was bred to work beside Swiss farmers all day, pulling carts through mountain valleys. That gentle giant following you everywhere? They're just doing what centuries of breeding told them to do.

Where Do Bernese Mountain Dogs Come From?

Bernese Mountain Dogs are an ancient breed from the Swiss Alps. They date back over 2,000 years to when Roman legions brought large mastiff-type dogs to Switzerland. Through centuries of farm work in isolated Swiss mountain valleys, they developed into large, strong, calm dogs suited to mountain farm life. They were nearly extinct by the early 1900s when machinery replaced them. Swiss breed enthusiasts revived them, but modern breeding from a limited gene pool has resulted in tragically short lifespans and extremely high cancer rates.

What were they bred to do?

• Drafting (pulling carts loaded with milk, cheese, and produce to market)
• Livestock droving (moving cattle between pastures and to market)
• Farm companionship and guarding (alerting to strangers but not aggressive)
• Working calmly alongside farmers through long days

Key breeding traits

These dogs were bred to be calm, steady workers who could pull heavy loads over 1,000 pounds in mountainous terrain. They needed to be gentle whilst being large and imposing enough to deter threats. They're "gentle giants" with massive size, incredibly sweet temperament, and moderate energy. They bond intensely to family and follow their person everywhere. They mature slowly, remaining mentally and physically immature until 2-3 years old. Unfortunately, they have significant health issues including tragically high cancer rates.

Why Do Bernese Mountain Dogs Have These Behaviour Problems?

Your Bernese was bred to work alongside farmers from dawn to dusk. They pulled carts, moved cattle, and stayed with their person constantly. That intense bonding wasn't a personality quirk. It was their job.

Modern Bernese still carry these genetics. They're not independent dogs who can handle being alone easily. They're shadow dogs who genuinely struggle when separated from their family. Their gentle, sensitive temperament means they don't bounce back from stress like tougher breeds do.

Their size creates another challenge. What's cute in a 15-pound puppy becomes dangerous in a 95-pound adult. That excited jumping? That's 95 pounds of dog with the brain of a toddler who hasn't learned manners yet.

Problem 1: Short Lifespans and Cancer Rates

What's happening: Bernese Mountain Dogs have the shortest average lifespan of any large breed at 6-8 years. Many die at 5-6 years old. Over 50% die from cancer, with histiocytic sarcoma being particularly aggressive and common.

Why it happens: Limited gene pool from the breed revival, breeding for appearance over health, and lack of genetic diversity created a health crisis. This isn't a behaviour problem, but it profoundly affects ownership and your dog's behaviour when they're unwell.

The fix:

• Only purchase from breeders doing extensive health testing: OFA hip/elbow certification, cardiac clearance, eye clearance, genetic testing minimum
• Interview breeders about lifespan in their lines—what's the average age of death, what do dogs die from
• Purchase pet insurance immediately covering cancer and hereditary conditions
• Watch for early cancer signs: unexplained lumps, lethargy, loss of appetite, weight loss, limping
• Budget for healthcare: expect $2,000-5,000+ annually in vet care even when "healthy"
• Appreciate their presence—these dogs give their whole hearts for a short time, so make their years count

Concerned about your Bernese's health monitoring? Our Skool community includes owners who've navigated cancer diagnoses and can share what early warning signs they spotted, plus connect you with others going through similar experiences.

Problem 2: Overexcitement With Physical Affection

What's happening: Your Bernese jumps on people, knocks them over with enthusiasm, pulls on the lead, and generally forgets they're a 95-pound dog. They're so excited to show affection that they become physically overwhelming.

Why it happens: Bernese were bred with gentle, loving temperaments. They genuinely adore their families. Combined with their massive size and slow maturation, they're essentially giant puppies who haven't learned manners yet.

The fix:

• Start training at 8 weeks before size becomes an issue—every allowed behaviour at 15 pounds becomes a 95-pound habit
• No jumping ever—everyone turns away and ignores until four paws are on the floor
• Loose lead walking from first walk using the "tree method"—if they pull, you stop until the lead loosens
• No furniture until invited to prevent resource guarding and maintain control
• Avoid extensive running or jumping until growth plates close at 18-24 months
• Use front-clip harness for walking—you need mechanical advantage during training
• Accept their personality—they're calm gentle giants requiring patience, not force

Problem 3: Separation Anxiety & Velcro Behaviour

What's happening: Your Bernese follows you everywhere. They panic when you leave. They cry, destroy things, or refuse to settle when alone. They're literally your shadow, moving from room to room with you constantly.

Why it happens: They were bred as farm dogs working alongside farmers all day. They're not independent dogs. Their gentle, sensitive temperament means separation causes genuine distress. Many owners inadvertently create separation anxiety by allowing constant companionship, then expecting them to handle absences.

The fix:

• Practice mini-departures 40-50 times on weekends: leave for 30 seconds, return and ignore completely for 5 minutes
• They must be calm before acknowledgment—let them calm down before you acknowledge them
• Teach "settle with purpose"—give them a specific job like "watch the house" when alone
• Use graduated departure cues: pick up keys 20 times without leaving before using them to actually depart
• Desensitise leaving rituals by doing them randomly throughout the day without leaving
• Practice departures starting with just 20 seconds, building slowly
• When returning home, freeze completely—no movement, speaking, or acknowledgment until they settle

Finding separation training overwhelming? Our Skool community provides step-by-step separation protocols specifically for velcro breeds, plus troubleshooting when your Bernese regresses during training.

Is a Bernese Mountain Dog Right for a New Owner?

Bernese Mountain Dogs can work for new owners if you're prepared for the commitment and understand the health realities.

A gentle family dog - Bernese are known for their patience with children and calm temperament. Despite their massive size, they're trustworthy and gentle with families when properly trained.

A loyal companion - These dogs form incredibly strong bonds with their families. They were bred to be steady, reliable companions to farmers. That loyalty and devotion remains today.

A moderate energy dog - Unlike high-drive working breeds, Bernese don't need constant intense activity. They're happy with regular walks and moderate exercise rather than marathon runs.

A trainable dog - Their gentle nature and desire to work with humans makes them responsive to training. They want to please their families and respond well to positive methods.

A striking appearance - The tri-colour coat pattern is genuinely beautiful. These dogs turn heads wherever they go and their appearance matches their gentle personality.

Bernese Mountain Dogs require commitment to training their large size, managing separation anxiety, living in cool climates, and facing the reality of short lifespans. They're wonderful dogs for owners prepared for these challenges.
