¶Quick Facts
- The Bernese Mountain Dog is a large Swiss farm dog originally used for guarding, draught work and driving cattle. Today, it is primarily a companion and versatile working dog.
- Males stand 64–70 cm at the withers, with 66–68 cm preferred. Females stand 58–66 cm, with 60–63 cm preferred. The breed standard does not specify a weight.
- The breed should be self-confident, attentive, good-natured and devoted to its family, as well as friendly towards strangers.
- An adult needs substantial activity every day. Puppies and young dogs should not be given structured conditioning work or heavy physical loads.
- The long double coat normally needs a thorough brush each week, and more often during moulting.
- In Sweden, both parents must have official hip and elbow results before mating. The HS test for histiocytic sarcoma estimates risk; it does not say that a dog is healthy or affected.
- Tumours and low longevity are the breed's most serious health concerns. The lifespan and documented causes of death among relatives therefore matter when choosing a puppy.
¶Appearance & Coat
The Bernese Mountain Dog is large and powerful, but it should also be mobile, harmonious and well balanced. Its body is roughly ten per cent longer than its height at the withers and should look compact rather than elongated. A heavy outline is not the same as correct breed type: the dog should move freely and carry its size without being overweight.
Males should stand 64–70 cm, ideally 66–68 cm. Females should stand 58–66 cm, ideally 60–63 cm. The breed standard gives no weight range. Assess an adult by its proportions, muscle and body condition instead of aiming for a particular number on the scales.
The head should be powerful without being too heavy. The eyes are dark brown and almond-shaped, and the ears are medium-sized and triangular. The bushy tail reaches at least to the hock and hangs down when the dog is relaxed, but may rise to the level of the back when moving.
The coat is long and glossy, either straight or slightly wavy. The base colour is jet black, with rich rust markings on the cheeks, above the eyes, on the legs and on the chest. White appears in places including a symmetrical blaze and the throat and chest. White feet and a white tail tip are desirable, but symmetry of markings says nothing about a dog's health.
The Swedish Kennel Club's breed guide recommends brushing or combing once a week and daily during moulting. Adapt this to the individual dog and the season. Work down to the skin and check behind the ears, in the armpits and through the feathering, where tangles can hide. At the same time, feel for lumps, tenderness and changes to the skin.
Schedule longer summer activities for cooler parts of the day, provide shade and water, and let the dog rest if it is not recovering normally. Never leave a dog in a hot car, even in the shade or with a window partly open.
¶Temperament & Personality
A typical Bernese Mountain Dog should be confident, good-natured and biddable, not fearful or aggressive. The standard also describes an attentive, watchful dog that is devoted to its family and friendly towards strangers. This is a breeding and temperament goal, not a guarantee for every puppy or every situation.
The breed is often sociable and willing to cooperate, but a boisterous adolescent of this size can knock over a child, pull an adult off balance or crowd a visitor without any aggressive intent. From an early age, teach four paws on the floor, calm greetings, loose-lead walking and settling in a designated place.
Socialisation does not mean making the puppy greet everyone. Offer calm experiences of people, dogs, traffic, surfaces, handling and different environments, while allowing it to watch from a distance. Repeated fearfulness should be taken seriously rather than dismissed as the breed being “sensitive”.
A Bernese Mountain Dog can live successfully with children and other animals, but the individual and the introduction make the difference. Children should not climb on the dog or disturb it when sleeping. The dog needs a quiet resting place, and an adult should always supervise interactions between dogs and young children.
¶Training & Exercise
An adult Bernese Mountain Dog needs proper exercise and meaningful activity every day, but there is no universal number of minutes. Adapt the amount to age, body condition, health, fitness, surface and temperature. Walks with time to sniff, everyday training, scent work and play create a better routine than simply trying to exhaust the dog.
For puppies and young dogs, the Swedish Kennel Club distinguishes natural movement from deliberate exercise. Let the dog move at its own pace and rest when needed. Planned runs, repeated jumping and heavy draught work should wait until the dog is physically mature. Do not rely on a simple five-minute rule; adjust activity according to the dog's movement, fatigue and recovery.
Short, clear, reward-based sessions work well. Prioritise skills that become difficult to teach only after the dog has reached its full size:
- walking on a loose lead and turning with the handler
- greeting without jumping up or leaning its full weight against someone
- recall and engagement around distractions
- waiting at doorways and getting calmly in and out of the car
- cooperative handling of paws, mouth, ears and coat
The breed's heritage can be channelled into scent work, obedience, rally, carrying a dog pack, or the breed club's draught and working tests. Pulling a load requires suitable equipment, gradual preparation and a physically mature, healthy dog.
¶Health
Health and longevity must carry considerable weight when choosing a Bernese Mountain Dog. The current Swedish breeding strategy identifies tumours as the breed's greatest health problem and shows that low longevity remains an issue. Even so, nobody can promise how many years an individual dog will live.
In the Swedish insurance mortality data for 2016–2021 reported in the breeding strategy, the median age was 5.5 years. In a Swiss study of club-registered dogs born in 2001–2002, median survival was 8.4 years. The populations, periods and methods differ, so these figures are not the same kind of forecast. They show why health and longevity in close relatives are more useful than one general range.
Tumours accounted for more than half of deaths in both a Swiss and a Dutch study. Histiocytic sarcoma is the tumour type specifically targeted by the breed's health programme. The HS test places dogs in lower, average or higher genetic risk groups relative to the breed. It is not a diagnostic test: a lower-risk dog may still develop the disease, while a higher-risk dog may remain healthy.
HSIMS estimates the risk of a proposed mating from the parents' HS results. It must be considered alongside longevity, other aspects of health, relatedness and function. Selecting solely for the lowest risk would reduce genetic diversity. The Swedish breeding strategy recommends HS testing, but it is not required for registration with the Swedish Kennel Club. Since 2025, however, the Swedish Sennenhund Club's puppy-listing service has required both parents to be tested.
Both parents must have official hip dysplasia and elbow dysplasia status before mating for their offspring to be registered with the Swedish Kennel Club. Dogs with HD grades D or E and ED grades 2 or 3 must not be used. The breeding strategy also recommends parents free from ED and a combined HD and ED index above 100. An index of 100 is the breed average and incorporates information from relatives, so indices and the results of screened littermates reveal more than one isolated result.
Renal dysplasia, or RD, is a serious developmental kidney disorder that mainly affects young dogs. Confirmed cases are recorded centrally, and a definitive diagnosis requires examination of kidney tissue. Familial nephropathy is another documented kidney disease and more often affects young adults. There is no simple DNA test that can show that a proposed mating is free from the inherited risk behind these diseases.
Ask the breeder to show and explain:
- the parents' official hip and elbow results and the proposed mating's current indices
- how many littermates and previous offspring have been screened, and their results
- HS results and how HSIMS and genetic diversity have been taken into account
- kidney disease, tumour diagnoses, longevity and verified causes of death among parents, siblings and older relatives
¶History & Origins
The Bernese Mountain Dog has a documented history as a farm dog in the Alpine region around Bern, Switzerland. It guarded farms, pulled loads and helped with cattle. The dogs were known as Dürrbächler after the Dürrbach inn near Riggisberg, where the long-haired, tricoloured type was common.
Dürrbächler dogs were shown at dog shows in 1902, 1904 and 1907. In November 1907, breeders around Burgdorf founded the Schweizerischen Dürrbach-Klub to breed the dogs to a consistent type and define their characteristics. The name Bernese Mountain Dog was later established in relation to the other Swiss mountain dog breeds.
The claim that the breed descends from Roman mastiffs is often repeated, but it is not part of the securely documented history. The reliable account centres on the local farm dog around Bern, its work in guarding, draught and cattle handling, and the organised development of the breed in the early twentieth century.
¶Living with the Breed
A Bernese Mountain Dog needs practical space in daily life, not just enough floor area. Flat living can work, but check the stairs, lift, slippery floors, access to suitable walking areas and how an ill dog could be transported. A garden is useful, but it does not replace walks and shared activity.
Plan for a large bed, a car and harness that can accommodate the dog, food, insurance and somewhere to dry a wet coat. Add non-slip surfaces where needed. It is better to solve these practical issues while the dog is young than when it is in pain.
Time alone must be trained to suit the individual. Begin with very short separations while the dog is settled, and increase them only when it can lie down and relax. Persistent whining, pacing, panting or scratching shows that the step was too difficult. The breed's devotion does not prove that it will have separation problems, but nor does it guarantee that a dog can cope with a whole working day alone.
Introduce dogs and cats gradually. Keep them apart at first, let them become used to each other's scent, give the cat a dog-free place and prevent the dog from chasing. Brief meetings through a gate or with the dog on a lead can then be extended when both animals are relaxed. The same calm principle applies when meeting other dogs; the Bernese Mountain Dog's size makes early lead control particularly important.
A good breeder can discuss both strengths and problems in the family and provides documentation, not merely the names of tests. Choose a mating in which health, temperament, function and genetic diversity have been considered together. Openness about ill and deceased relatives is at least as valuable as good results for the parents.

¶Frequently Asked Questions
What is the typical temperament of a Bernese Mountain Dog with family and children?
They are generally gentle, patient, and very people oriented, which makes them well suited to families with respectful children. Most are affectionate and eager to please, but their large size and strength mean they should be supervised around small children and taught basic manners from an early age.
How much exercise does a Bernese Mountain Dog really need each day?
They need moderate but consistent exercise, usually around 60 to 90 minutes of activity spread throughout the day. Long walks, hiking on cooler days, and light draft work suit them well, while intense running or exercise in hot weather should be avoided due to their heavy coat and build.
Are Bernese Mountain Dogs good apartment pets, or do they need a large yard?
They can adapt to apartment living if they receive enough outdoor exercise and mental stimulation, but many do best in a home with easy access to a secure yard. Their size, shedding, and tendency to track in mud and snow are important considerations for smaller living spaces.
What are the most common health problems in Bernese Mountain Dogs?
They have a relatively high risk of cancers such as histiocytic sarcoma, along with hip and elbow dysplasia, bloat, and certain heart and eye conditions. Responsible breeders screen for orthopedic and genetic issues, but prospective owners should still be prepared for potentially higher veterinary needs than with many other breeds.
Why is the lifespan of Bernese Mountain Dogs often shorter than other breeds?
Their shorter average lifespan is largely linked to a high incidence of malignant cancers and some inherited health conditions. Breeding practices, body size, and limited genetic diversity have also played a role, although many breeders are working to improve longevity through careful selection.
How much do Bernese Mountain Dogs shed and what grooming do they require?
They are heavy shedders with a thick double coat that sheds year round and more heavily in seasonal bursts. Brushing several times a week helps control loose hair and prevent matting, and owners should be prepared for regular vacuuming and fur on furniture and clothing.
Can Bernese Mountain Dogs tolerate hot weather?
They are much better suited to cool or cold climates due to their dense coat. In warm or humid conditions they should be exercised only during cooler parts of the day, given plenty of shade and water, and monitored closely for signs of overheating.
Are Bernese Mountain Dogs prone to separation anxiety or clingy behavior?
Many form very strong bonds with their families and prefer to be near their people most of the time. If left alone for long hours on a regular basis they can become stressed or develop unwanted behaviors, so they are usually a better fit for homes where someone is around much of the day.
How trainable are Bernese Mountain Dogs and what training challenges are common?
They are intelligent and generally eager to please, which makes positive reinforcement training effective. Some can be sensitive or a bit slow to mature, so they benefit from patient, consistent guidance, early socialization, and careful handling during their rapid growth phase.
Is a Bernese Mountain Dog a good choice for a first time dog owner?
They can be suitable for dedicated first time owners who are prepared for a large, shedding, relatively short lived breed with notable health risks. New owners should be ready to invest in training, socialization, grooming, and potentially higher medical costs over the dog’s lifetime.¶Comparisons with other breeds
