Bernese Mountain Dog: Why the Time Together Is So Short

Bernese Mountain Dog: character, care and everyday life with the breed

The Bernese Mountain Dog is one of the most popular large family dogs in Germany, and for good reason: he is calm, friendly, patient with children and looks like a soft toy that someone accidentally made very big. There is only one catch, and it is so big that it overshadows everything else. It is rarely talked about honestly on a visit to the breeder: you will probably lose this dog early.

Breed profile

Origin: Switzerland, canton of Bern, originally a farm and draught dog on farms
Size: males 64 to 70 cm, females 58 to 66 cm, 40 to 50 kg
Coat: long, slightly wavy, tricolour black with rust-brown and white markings
Life expectancy: around 8 years, clearly less than in other breeds of comparable size
Temperament: good-natured, calm, affectionate, watchful without sharpness, late maturing

Temperament: calm on a large scale

A well-raised Bernese Mountain Dog is an exceptionally relaxed dog. He rarely barks without reason, is hardly thrown by commotion and seeks the closeness of his people without being pushy. He is usually very patient with children, although his weight alone is reason enough to supervise contact with small children.

He is not a dog who demands tasks. He is content with shared walks, quiet evenings and the certainty of belonging. At the same time he matures late: until about his second year he remains a puppy inside the body of a fully grown dog, which occasionally leads to clumsy moments.

Historically the Bernese was an all-rounder on Swiss farms: he guarded the farm, drove cattle and pulled carts with milk churns. This past explains his composure and his strength, but also his closeness to people. He was never bred as an independently working dog, but always as one who stays with the family.

What you should know beforehand

1. The short life expectancy is the central issue

An analysis of 9,453 Bernese Mountain Dogs from the German population, birth years 1995 to 2008, found a mean life expectancy of 8.25 years. That puts the breed among the shortest-lived of all, even compared with other large dogs. Many owners lose their dog just as he has really become an adult. This is not a side note, but the most important point you should really think through before getting one. If you cannot imagine that, it is not a good choice.

2. Tumour diseases are the main reason

In the same analysis, 61 percent of all documented deaths were due to tumour diseases, far ahead of kidney disease at 10 percent. Histiocytic sarcoma in particular occurs much more often in this breed than in others and usually runs a fast and aggressive course. Lymphomas and mast cell tumours are added to that. Reputable breed clubs are working on it, but there is so far no reliable screening or genetic test.

3. Joints and growth need care

Hip and elbow dysplasia are widespread, so X-rayed parent animals are a must. During the growth phase, up to about 18 months, stairs, jumping out of the car and long ball games harm the open growth plates. Because of the deep chest there is also an increased risk of gastric torsion, an acute emergency that has to be operated on within a few hours and costs 2,000 to 4,000 euros depending on the clinic.

4. Heat is a real problem for him

The dense, long coat comes from the Swiss mountain climate. On a German summer day of 30 degrees, a Bernese Mountain Dog is quickly overwhelmed. Walks then have to be moved to the early morning and late evening hours, and in the car or in heated-up flats it quickly becomes dangerous for him. Anyone who cannot offer a cool retreat should think carefully about the breed.

5. The running costs are high

A puppy from a tested breeder via the VDH costs 1,800 to 2,500 euros. After that the real expense begins: food for a 45-kilo dog, grooming, and above all vet costs, which statistically arise earlier and higher in this breed than in others. Health insurance, or at least surgery insurance, is not a consideration here but a necessity. Over the dog's life, expect a clearly higher amount than for a medium-sized dog.

Care: what he really needs

Calm, regular exercise. Long leisurely walks instead of sprinting and ball throwing. He is not a sports dog.
Cool retreats. A shady spot, a cool floor, adjusted walk times in summer.
Consistent grooming. Brush two to three times a week, daily during the moult. More on this in our article on Moulting.
Protecting the joints during growth. No stairs, no jumping out of the car, no long strain in the first year of life.
Closeness to the family. He is not a kennel dog. Kept alone outside, he withers inside.

Who is the Bernese Mountain Dog right for?

For families and quiet households looking for a large, easygoing companion and who don't want to do dog sport. For people with enough space, a cool home and the financial reserve for high vet costs. And above all for people who consciously decide to spend a short, intense time with a special dog instead of hoping for twelve or fourteen years.

Not for athletically ambitious people looking for a running partner. Not for small city flats on the fourth floor without a lift, because a sick 45-kilo dog will have to be carried at some point. And not for anyone who would rather push away the thought of an early goodbye, because it will very probably come.

If this weighing-up is making you brood right now, that is a good sign. That is exactly what Welcher Hund passt WIRKLICH zu dir? (Which dog REALLY suits you?) is about: not the most beautiful breed, but the one that fits your daily life, your budget and your resilience.

Frequently asked questions

Do all Bernese Mountain Dogs only reach eight years? No, there are dogs who reach ten years and older. But the average is clearly lower than in other breeds, and there are solid figures for it: 8.25 years mean life expectancy in an analysis of 9,453 dogs of the German population. Plan realistically, not for the exception.

Can a breed club lower the risk? Partly. X-rayed, health-checked parent animals clearly lower the risk of joint problems. For histiocytic sarcoma this option does not exist so far. Ask the breeder openly about the life expectancy of his previous litters.

Is he a good first dog? In training, yes, he is good-natured and willing to learn. In responsibility, rather not, because size, costs and health issues are a lot at once for beginners.

And on the portrait?

The tricolour markings with the rust-brown patches above the eyes are unmistakable and show up particularly warmly in classic oil painting portraits. Photograph him from the side or slightly from the front at an angle in daylight, so that the coat texture stays visible and the face doesn't disappear in the dark fur. With this breed in particular, it is worth not putting the portrait off.

A small format is rarely enough for a Bernese. The dog is big, so the picture may be too: as a poster, in a wooden frame or on canvas. If you have already had to say goodbye, our article on Saying Goodbye to a Dog may hold a few helpful thoughts.
