The Bernese Mountain Dog typically weighs 35-55 kg, stands 58-70 cm, and lives 7-10 years.

Consider this breed if…

you want a calm, deeply affectionate family dog and have room for a big one,
you can handle heavy shedding and regular brushing,
someone is home for much of the day - this breed hates isolation,
you have budgeted for large-breed vet care and a possibly short life.

Do not consider this breed if…

a short lifespan and high cancer risk would be too painful to take on,
you live in a small flat with no easy outdoor access,
you want a jogging or endurance partner,
your summers are hot with no way to keep a heavy-coated dog cool.

Frequently asked questions

How much does a Bernese Mountain Dog cost?
Expect roughly $1,200-$2,500 from a health-testing US breeder. The purchase is only the start: a 35-55 kg dog means higher food, medication, and surgery bills for life, and the breed's high cancer rate and joint problems can bring major costs. Insurance or a real emergency fund is strongly advisable, and lifetime costs easily run into five figures.
Are Bernese Mountain Dogs good family dogs?
Yes - this is one of the gentlest, most patient family breeds, devoted to children and calm in the home. The hard part is not temperament but longevity: the breed's short lifespan and cancer risk mean many families face loss earlier than they expect. Go in loving the dog and prepared for that reality.
How long can a Bernese Mountain Dog be left alone?
An adult can handle around half a workday once settled, but this breed bonds hard to its family and dislikes isolation. Regular full days alone tend to produce stress and clinginess. A household with someone home for much of the day is a much better fit.
Do Bernese Mountain Dogs shed a lot?
Yes. The thick, long double coat sheds heavily year-round with bigger seasonal blowouts, so plan on brushing several times a week and living with hair on everything. They also feel heat badly - keep them cool in summer.
