Saint Bernard
SAYNT bur-NARD
Watchful, Patient, Gentle, Friendly. Originally bred for alpine rescue and avalanche search.
An adult Saint Bernard weighs 140-180 lbs (male) or 120-140 lbs (female), needs 1,400-2,660 calories daily, and lives 8-10 yrs. Giant breeds grow slowly and need careful nutrition management during their extended puppyhood. The breed's primary health watch is hip dysplasia. All numbers below come from AKC breed standards and NRC 2006 veterinary nutrition formulas.
Nutrition and feeding
A typical adult Saint Bernard needs 1,400 to 2,660 calories per day. An average male (160 lbs / 72.6 kg) needs around 2,090 kcal; a female (130 lbs / 59.0 kg) roughly 1,790 kcal. These estimates use the vet-standard RER/MER formula.

Health profile
Giant breeds have shorter lifespans than smaller dogs, and the Saint Bernard is no exception at 8-10 yrs. Their large frames put stress on joints, hearts, and skeletal systems. The breed's primary health concerns are hip dysplasia and elbow dysplasia, which responsible breeders screen for before breeding.
Exercise and activity
Low to moderate; short walks in cool weather. Saints overheat easily due to their massive size and thick coat. Avoid intense exercise, especially in warmth. Working breeds like the Saint Bernard were developed for specific physical tasks. They need purposeful activity, not just wandering around a yard. Structured exercise with clear tasks, such as carrying a dog pack on hikes, pulling a cart, or advanced obedience training, satisfies their need to work.
Care and traits
Saint Bernards have a short or long varieties; thick, dense coat. Origin: Switzerland/Italy (Great St. Bernard Pass).
The famous barrel around their neck is largely a myth (popularized by a painting, not actual rescue practice). Historically saved over 2,000 travelers in the Swiss Alps. They drool profusely. Despite their gentle nature, their sheer size means they can accidentally knock over children or fragile adults.
Heavy shedding is a reality with this breed. Expect dog hair on furniture, clothing, and in every corner of your home. A good vacuum, lint rollers, and acceptance are your best tools. Shedding typically increases during seasonal coat changes in spring and fall.
Living space matters for a breed this size. They need room to move without knocking things over, and many giant breeds prefer cool environments. Heat tolerance is limited; monitor closely in warm weather. Elevated food and water bowls may improve comfort during meals.

Frequently asked questions
Daily calorie needs for a Saint Bernard range from 1400 to 2660 kcal. A 160-pound individual falls near the middle of that range. Giant breeds need split meals, ideally two to three times daily, to reduce the risk of gastric dilatation-volvulus (bloat). Active dogs need more; seniors and less active individuals need less. Use our calorie calculator with your dog's actual weight for a personalized number.
Males typically weigh 140-180 lbs (63.5–81.6 kg). Females run lighter at 120-140 lbs (54.4–63.5 kg). Giant breeds should appear muscular and solid but never round. Because they carry so much mass, even moderate overweight significantly stresses joints and shortens lifespan. Run your hands along the ribcage: you should feel ribs under a thin layer of flesh without pressing hard. From above, look for a visible waist narrowing behind the ribs.
Hip dysplasia is the primary health concern vets flag for Saint Bernards. Hip dysplasia is a developmental condition where the hip joint doesn't fit together properly. Screening through OFA or PennHIP before breeding is standard practice. In pet dogs, maintaining a lean body weight is the most effective way to manage and slow progression. Other conditions seen in the breed include elbow dysplasia, bloat, osteosarcoma. Not every Saint Bernard will develop these conditions, but knowing the breed's tendencies helps you and your vet monitor proactively.
About 20 to 30 minutes of daily activity keeps a Saint Bernard in good shape. Good activities for this breed include structured tasks, cart pulling, obedience drills. Avoid high-impact exercise (jumping, stairs) during the growth phase to protect developing joints. Even low-energy breeds need daily movement for joint health, weight management, and mental well-being.
