Saint Bernard
Also known as: St. Bernard, Bernhardiner, Alpine Mastiff
The legendary alpine rescue dog of the Great St Bernard Hospice - a gentle, patient giant that is wonderful with children and famously good-natured. Calm, devoted and deeply affectionate, the Saint Bernard is a warm-hearted gentle giant with a heritage as extraordinary as its personality.
Origin and purpose
The Saint Bernard was developed by monks at the Great St Bernard Hospice in the Swiss Alps from the 18th century as a powerful, sure-footed dog to find and rescue travellers lost in the snow. The breed became a symbol of mountain rescue, with the famous dog Barry credited with saving many lives.
Temperament
Breed authorities describe the Saint Bernard as friendly, calm, patient and gentle — exceptionally tolerant with children and steady in temperament. It is moderate in energy and trainable, though early manners training matters given the eventual size. As ever, behaviour reflects the individual dog and its raising far more than the breed (Morrill et al., Science 2022).
Health and longevity
Giant size brings a short lifespan and predisposition to several heritable conditions. Buy from breeders who screen hips, elbows, heart and eyes.
Common health conditions
Living with a Saint Bernard 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
