Bernese Mountain Dog
Also known as: Berner Sennenhund, Bernese
A large, strikingly handsome tricolour Swiss farm dog - gentle, affectionate and devoted, famously good with children. Calm, patient and eager to please, the Bernese Mountain Dog is one of the most endearing large working breeds, with a loyal nature and deep love of family life.
Origin and purpose
The Bernese Mountain Dog is one of four Swiss Sennenhund (alpine herdsman) breeds, traditionally a general-purpose farm dog in the canton of Bern that pulled carts, drove cattle and guarded the homestead. The modern breed was standardised in the early 20th century as the farm dog declined.
Temperament
Kennel clubs describe the Bernese as good-natured, calm, affectionate and self-confident, devoted to its family and especially gentle with children. It is trainable and eager to please but can be slow to mature and sensitive to harsh handling. Individual temperament, of course, varies far more than breed alone predicts (Morrill et al., Science 2022).
Health and longevity
The Bernese has one of the shortest lifespans among large breeds. Buy from breeders who screen joints and breed for longevity.

Living with a Bernese Mountain Dog in Tokyo
This section is specific to Tokyo (Ministry of Agriculture, Forestry and Fisheries (MAFF)). The rest of this guide applies to the breed anywhere.
Tokyo Metropolitan Animal Care & Consultation Center: Not eligible
This breed is not eligible for Tokyo Metropolitan Animal Care & Consultation Center.
Licensing
Dog registration required under the Rabies Prevention Act (狂犬病予防法): one-time ward office registration fee ¥3,000 + annual rabies vaccination tag ~¥550. Microchipping mandatory for dogs sold from breeders/pet shops since June 2022 (Act on Welfare and Management of Animals).
Climate & exercise in Tokyo
Tokyo is humid subtropical; hot humid summers (Jul–Sep, avg 35°C+); mild winters (Dec–Feb, avg 10°C); cherry-blossom spring; typhoon season Aug–Oct. walk before 7am or after 7pm in July–September; Tokyo pavements reach 50–60°C in direct sun at midday — test with your hand before walking. Tokyo summers (July–September) are dangerously hot and humid; heatstroke is the #1 summer risk for dogs. Flat-faced breeds (French Bulldog, Shih Tzu, Pug) and double-coated breeds face the highest risk. Tokyo urban heat island effect means temperatures stay high overnight — do not rely on evening walks alone in heatwave conditions.
Parasite prevention
Plan for Heartworm prevention essential May–November (Aedes albopictus and Culex tritaeniorhynchus active); tick prevention recommended for dogs accessing Okutama, Takao-san, Tanzawa and other Kanto forest areas year-round.
Cost of ownership in Tokyo
Local Bernese Mountain Dog cost figures for Tokyo are being verified. Budget for purchase or adoption, initial setup, food, grooming, routine veterinary care, parasite prevention and pet insurance. Figures are quoted in ¥.
Health & longevity
Responsible breeders health-test their breeding dogs. Ask to see current certificates before committing.
Nutrition note: Giant-breed controlled-growth puppy diet; keep lean to limit joint load; the breed's key risk is cancer, not obesity per se.
