Bernese Mountain Dog: Size, Lifespan and Care Basics

The American Kennel Club (AKC) gives the Bernese Mountain Dog a life expectancy of 7 to 10 years. The Royal Kennel Club (RKC) in the UK puts the breed in its “under 10 years” band.

Both figures describe the breed as a whole. They are ranges for typical dogs of the breed, not a forecast for any one dog.

Of the 30 breeds profiled on Pettify, 26 have a longer upper estimate than the Bernese Mountain Dog and 0 a shorter one.

The RKC suggests grooming a Bernese Mountain Dog more than once a week and describes the coat as medium; it lists the breed as one that sheds. On the AKC’s scales the breed rates 5 out of 5 for shedding and 3 out of 5 for how often the coat needs care.

Of the four Swiss mountain dog breeds, the Bernese is the only one the AKC describes with a long, silky coat, though both clubs class its length as medium. Beneath the outer hair sits a woolly undercoat, and loose hair comes out all year, more of it in the two shedding seasons.

Outside those seasons the AKC’s weekly brush is enough; once one starts, it moves to a daily brush, with a metal comb or a slicker brush for any tangles. The RKC’s standard colour is tricolour, which the AKC spells out as black, white and rust.

The RKC puts the exercise a Bernese Mountain Dog needs at up to 1 hour a day. The AKC rates the breed 4 out of 5 for energy and 3 out of 5 for mental stimulation needs.

Draft work is in the breed’s past, and the AKC says Berners still enjoy it, pulling young children in a cart among other things. In America the national breed club holds drafting and carting events that test that old skill.

Long walks and hikes suit the breed, and some owners take their Berners camping and backpacking, by the AKC’s account. The AKC sets a floor of half an hour of moderate exercise a day. Indoors, by the same account, a Berner is happy to relax.

The AKC gives the adult weight of the Bernese Mountain Dog as “80–115 pounds (male), 70–95 pounds (female)”, which is 36.3–52.2 kg for males and 31.8–43.1 kg for females. The height at the shoulder is 25–27.5 inches (male), 23–26 inches (female).

The name comes from the canton of Bern, a farming region of Switzerland known for its dairy. Berners drove cattle, guarded farmyards and pulled carts, in the RKC’s account hauling goods for the local weavers and carts of milk and cheese. By the late 1800s their numbers were falling, and Swiss fanciers set out to save the breed; a breed club followed in 1907.

In Switzerland the old trade lives on in parades, where Berners pull light carts and their owners wear national costume. The American story began in 1926, when a Kansas farmer imported a pair as farm dogs, and the AKC registered its first Berner in 1937. In 2025 the breed ranked 20th in AKC registrations.

On the AKC’s social scales the Berner sits at the top. Young children rate 5 out of 5, other dogs 5 out of 5 and affection for family 5 out of 5, and the AKC’s words for the breed are good-natured, calm and strong. Strangers get a friendly 4 out of 5, though the AKC describes a certain dignified reserve toward people the dog does not know.

As a guard the breed is middling, at 3 out of 5; it impresses by size rather than by menace. Expect some barking (3 out of 5) and some drool (3 out of 5). Trainability rates 4 out of 5, and the AKC describes a dog eager to please its owner, which helps when that owner is steering a large, strong animal.

The practical side comes down to size. A large house and a large garden is the RKC’s recommendation, in town or country alike, and the AKC is clear that Berners are meant to live indoors with their family. Pettify’s care plan keeps a Berner in the puppy stage until 15 months.
