Bernese Mountain Dog
A Swiss farm dog that pulled milk carts and moved cattle around Bern. Gentle, biddable and genuinely family-oriented, but a seven-to-ten-year lifespan and a high cancer rate make this a breed you take on with open eyes.

Background and characteristics
Berners come from the farms of the Swiss canton of Bern, where one dog was expected to haul a cart of milk cans to the village, help move cattle and keep an eye on the property. Every part of that work happened next to a person, which is why the modern Berner is so oriented toward its family and so quick to take direction. It is also why the breed does badly with long solitary days and shuts down under harsh handling.
Big dog, soft temperament.
Exercise and play
Plan on forty-five to sixty minutes of steady daily walking. This is a distance-at-a-walk dog rather than a sprinter, and it visibly comes alive in cold weather while wilting in heat. Carting and drafting clubs give the breed a useful outlet that works the body and the head at once, and hiking in cool seasons suits it perfectly.
Puppies need managed, not maximized, exercise: skip repeated stairs, jumping and running alongside a bike until around eighteen months, because hips and elbows are the joints this breed cannot afford to compromise.
Coat and everyday care
The long outer coat over a dense undercoat wants brushing two or three times a week down to the skin, with particular attention behind the ears, behind the front legs and on the trousers. Twice a year the undercoat comes out in quantity. No scissoring is needed beyond tidying feet and sanitary areas.
The coat is mostly black, so it shows on light floors and light clothing more than most.
Coat and everyday care (2)
The hard part of owning this breed is not the grooming, the training or the size. It is the timeline. Seven to ten years is short even by giant-breed standards, and histiocytic sarcoma appears in Berners at a rate that has made the breed a focus of veterinary cancer research; mast cell tumors and lymphoma also show up.
Hip and elbow dysplasia and gastric dilatation-volvulus are the other watch items. Buy from a breeder who screens hips, elbows and eyes and who talks openly about what their lines have died of, and start insurance while the dog is young.
Home environment and care planning
Climate should drive the decision as much as space. Berners do well through a New England or British winter and struggle badly in a Texas or Queensland summer, so anywhere hot means air conditioning, early and late walks, and a hard stop on midday activity. In the house, put down runners on hardwood and tile; traction directly affects how long those joints hold up.
Given cool weather, company most of the day and a family that wants a dog leaning against their legs, few breeds are more rewarding for the time you get.
