Bernese Mountain Dog

The Bernese Mountain Dog is a large Swiss working breed developed as a versatile farm and draught dog. Recognisable by its long tricolour coat, it is often friendly and devoted, although every dog has an individual temperament. Prospective owners should be prepared for heavy shedding, patient reward-based training, suitable exercise, careful management in warm weather and informed health screening, including discussion of hips, elbows, degenerative myelopathy and family longevity.

History & Origin

The Bernese Mountain Dog originated in Switzerland and takes its English name from the canton of Bern. It is one of the Swiss mountain-dog breeds and developed as a versatile working companion on farms rather than for one narrowly defined task.

Its sturdy build allowed it to perform draught work, including pulling carts, while the breed also helped with general farm duties and moving livestock. Modern Bernese Mountain Dogs are principally companions, but their size, working background and relatively slow physical maturity still influence their everyday care.

What Were Bernese Mountain Dogs Bred to Do?

Bernese Mountain Dogs were bred as adaptable farm dogs. Their historic roles included pulling light carts, watching over the farm and assisting with cattle. Strength, steadiness and a willingness to work closely with people were therefore valuable qualities.

Today, suitable activities can include steady walks, scent work, reward-based training and other low-impact tasks that engage both body and mind. Exercise should always suit the individual dog rather than trying to recreate demanding historic work.

Bernese Mountain Dog Size, Weight & Appearance

The Bernese Mountain Dog is a large, strong and sturdy breed. The current UK breed standard gives a height at the shoulder of 64–70 cm for dogs and 58–66 cm for bitches. It does not prescribe a fixed weight, so healthy weight should be judged from the individual dog’s frame and body condition with veterinary guidance where needed.

The coat is long and may be straight or slightly wavy. Its characteristic colouring is black with rich reddish-brown markings on the cheeks and legs, together with defined white markings. The overall appearance should be balanced and capable of working, without exaggeration.

Bernese Mountain Dog Temperament & Everyday Life

The breed standard describes the Bernese Mountain Dog as good-natured, friendly and self-confident. Many form close bonds with their household, but breed descriptions are only a guide: temperament also depends on genetics, early experiences, socialisation, training, health and environment.

Their substantial adult size means calm household manners are especially important. Interactions with children should always be supervised, and introductions to dogs or other animals should be gradual. Prospective owners should also plan for the space, transport, grooming and veterinary costs associated with a large dog.

Exercise & Mental Stimulation

The Royal Kennel Club lists up to around one hour of daily exercise as a broad guide, while Dogs Trust recommends adjusting activity to the individual. A healthy adult may enjoy daily walks, time to sniff and explore, suitable play and gentle opportunities to learn. Needs vary with age, fitness, health and personality.

Puppies are still developing and should not be pushed through repetitive, forced or high-impact exercise. Older dogs and those with joint, heart or other health conditions may also need an adapted plan. Because Bernese Mountain Dogs have a thick, dark coat, activity should be reduced or rescheduled in warm weather and fresh water and shade should be available.

Training & Socialisation

Patient, consistent and reward-based training should begin early. Useful priorities include recall, settling, polite greetings, cooperative handling and walking calmly on the lead. These skills become increasingly important as a puppy grows into a powerful adult.

Socialisation should be gradual and positive rather than overwhelming. Introduce a puppy carefully to different people, friendly dogs, surfaces, sounds, travel and routine care while allowing them space to retreat. An accredited reward-based trainer can help if fear, overexcitement or handling difficulties appear.

Do Bernese Mountain Dogs Shed? Grooming & Coat Care

Bernese Mountain Dogs shed, often heavily, and loose hair may increase seasonally. Their long coat normally needs brushing several times a week, with particular attention to areas that can mat, such as behind the ears and around the legs and tail. This guide to brushing and coat care explains how to make routine grooming more comfortable.

Introduce grooming through short, positive sessions and check the skin, ears, paws and nails regularly. Seek veterinary advice for persistent itching, hair loss, sore skin or ear problems. Clipping or shaving the coat is not a substitute for routine grooming and should be discussed with a suitably qualified groomer or vet if there is a medical or welfare reason.

How Long Do Bernese Mountain Dogs Live? Health & Lifespan

Published lifespan figures vary according to the population and research method. A 2024 UK study reported median survival of approximately 10.1 years for Bernese Mountain Dogs, while a 2016 Swiss study of 389 dogs reported a median of 8.4 years. These are population estimates, not a prediction for an individual dog.

The breed has recognised risks involving the hips and elbows, certain cancers including histiocytic sarcoma, and degenerative myelopathy. UK breed-club guidance recommends checking hip and elbow scores and discussing DNA testing for both known degenerative myelopathy variants, Exon 1 and Exon 2. Screening can inform breeding decisions but cannot guarantee that a dog will remain healthy.

Owners should also know the signs of gastric dilatation-volvulus, commonly called bloat or GDV. A suddenly swollen abdomen, repeated unproductive retching, marked restlessness, weakness or collapse requires immediate veterinary attention. Routine veterinary care, appropriate body condition and prompt investigation of changes in appetite, movement, breathing, energy or new lumps are important throughout life.

Feeding & Care Basics

Feed a complete, balanced diet appropriate for the dog’s life stage, size, activity and health. Growth should be steady rather than deliberately accelerated, and portions should be adjusted using body condition rather than relying on a generic breed weight.

Fresh water should always be available. Owners should ask their vet about an appropriate feeding routine, particularly for a growing puppy or a dog with digestive or other medical concerns. Healthy weight management matters because excess body weight increases strain on joints and can make movement and temperature regulation more difficult.

Ethical Sourcing & Adoption (UK)

Adoption may be possible through breed rescue or a general UK rehoming charity. Rescue staff should share what is known about the individual dog’s health, behaviour and home requirements and help decide whether the match is suitable.

Anyone buying a puppy should meet the mother with the litter and choose a breeder who is open about health, temperament and living conditions. Ask to see verifiable hip and elbow results, discuss testing for both degenerative myelopathy variants, and ask about cancer and longevity in the wider family. Results should be explained honestly: no screening programme removes every risk.

Legal Note (UK)

The Bernese Mountain Dog is not specifically named as a prohibited type in current UK government guidance. However, laws concerning dangerously out-of-control dogs apply to every breed, including incidents in private places. Owners must keep their dog under proper control and should also check local rules concerning leads, public spaces, livestock and access.
