Longevity
Life expectancy
The life expectancy of the Saint Bernard is generally between 8 and 10 years, which is consistent with the size of a giant dog. The quality of the diet, growth management, maintaining a proper weight and preventing joint disorders strongly influence its aging.
Build
A robust breed?
The Saint Bernard tolerates cold conditions well thanks to its mountain-dog build and its protective coat. On the other hand, its robustness must be qualified by its sensitivity to high heat, the load placed on its joints and the need for careful monitoring during growth.
Watch points
What to watch for
Health vigilance mainly focuses on locomotion, the eyes and the risk of gastric dilatation-volvulus. In this very large dog, prevention matters as much as treatment, with a measured lifestyle, well-managed meals and veterinary check-ups adapted to age.
Hip dysplasia : This orthopedic condition can affect the Saint Bernard like many giant dogs and permanently impair its mobility.
Elbow dysplasia : It can appear during growth or become apparent with age and requires careful monitoring of locomotion.
Entropion and ectropion : The eyelids can turn inward or outward, with irritation, tearing, and ocular discomfort.
Gastric dilatation-volvulus : The digestive risk exists in this large breed and justifies prudent management of meals and exercise.
Climate
Cold and heat tolerance
The Saint Bernard is very comfortable in cold weather, but tolerates heat poorly. In summer, it must have shade, fresh water and activities limited to the mildest hours. Intense exertion during heat peaks should be avoided.
Weight
Tendency to gain weight
Weight control is crucial in the Saint Bernard, because any excess weight increases the load on the joints and reduces ease of movement. An appropriate ration, regular weigh-ins and moderate but consistent activity help to limit complications related to its body mass.
Daily life
Good habits to keep it healthy
- Maintain a stable weight and monitor gait.
- Keep up with vaccinations, deworming and identification.
- Consult promptly in case of lameness, vomiting or lethargy.
Vaccination
Saint Bernard vaccines: vaccination schedule
Which vaccines for a Saint Bernard? Like all cats, the Saint Bernard receives essential vaccines from 8 weeks old: Typhus (panleukopenia) and Coryza. The kitten primary vaccination for Saint Bernard is given in several injections 4 weeks apart, followed by a first booster at 1 year, even if it lives in an apartment. Depending on its lifestyle (outdoor access, multi-cat household, shows, travel), your veterinarian may complete the protocol with vaccines against Feline leukemia (FeLV), Rabies and Chlamydiosis.
| Vaccine | Primary series | First booster | Then | Who for? |
|---|---|---|---|---|
Typhus (panleukopenia)Core Feline panleukopenia (cat parvovirus) | 8 weeks · 12 weeks · 3 months | 1 year | every year | All pets |
CoryzaCore Feline herpesvirus and calicivirus | 8 weeks · 12 weeks · 3 months | 1 year | every year | All pets |
Feline leukemia (FeLV)Lifestyle-based Feline leukemia virus | 8 weeks · 12 weeks | 1 year | every year | Outdoor cats, cats living in a group or in a cattery |
RabiesLifestyle-based Rabies | 12 weeks | 1 year | every year | Mandatory for travel abroad, cat shows and most boarding kennels |
ChlamydiosisLifestyle-based Chlamydia felis (contagious conjunctivitis) | 8 weeks · 12 weeks | 1 year | every year | Cats living in groups, catteries, show cats |
Adult Saint Bernard vaccine boosters are annual for cat flu and leukemia if it goes outdoors; for panleukopenia, a booster every three years is often sufficient after the first booster. Your veterinarian will adjust the schedule to your cat’s lifestyle.

Adopting well
Adopting a healthy Saint Bernard
Careful veterinary follow-up is recommended with orthopedic monitoring during growth, an eye examination in case of tearing or irritation and particular attention to abnormal digestive signs. In a serious breeding program, screening for dysplasia is one of the important points to check.
