Temperament: How They Differ in Practice

Saint Bernard Temperament

Saint Bernards are the quintessential gentle giant — patient, kind, and remarkably tolerant with children. They are calm, even-tempered dogs that move slowly and deliberately, rarely showing aggression. They are affectionate with family and politely friendly with strangers. Saints are not high-energy dogs; they are content with moderate activity. They are known for exceptional patience, making them excellent family dogs even with toddlers.

Bernese Mountain Dog Temperament

Bernese Mountain Dogs are gentle, affectionate, and moderately playful. They are more active than Saints but still calm by most standards. Berners are devoted to their family and initially reserved with strangers, warming up after a proper introduction. They can be sensitive and dislike harsh correction — positive reinforcement training is essential. They are versatile working dogs who excel at carting, herding, and drafting.

Health: Key Differences

Saint Bernard Health

Saint Bernards are prone to hip dysplasia (significant rate given size), elbow dysplasia, bloat (GDV), and various cardiac conditions. Epilepsy and cancer occur at above-average rates. The short lifespan (8–10 years) is typical of their size class.

Bernese Mountain Dog Health

Bernese Mountain Dogs have one of the highest cancer rates of any breed — estimated at 50–60% lifetime cancer risk, with histiocytic sarcoma as the primary cause. Hip and elbow dysplasia rates are also high. The average Berner lifespan is 7–10 years but cancer often cuts this short. Pet insurance is essential and should be purchased before any diagnosis.

Practical tip: Pet insurance is recommended for both breeds. Enroll as early as possible — ideally before any conditions are diagnosed — to avoid pre-existing condition exclusions.

Exercise Needs

Saint Bernard

Saint Bernards need 30–60 minutes of moderate exercise daily. They are not built for intense or sustained activity but enjoy leisurely walks and cool-weather outdoor time. Puppies must not be over-exercised during the 18–24 month growth period.

Bernese Mountain Dog

Bernese Mountain Dogs need 60–90 minutes of daily exercise. They are more active than Saints and enjoy hiking, swimming, and drafting activities. They overheat quickly in warm weather and should exercise during cooler parts of the day. Mental stimulation through training is equally important.

Grooming Requirements

Saint Bernard

Long-coated Saints need brushing 2–3 times weekly and professional grooming every 6–8 weeks. Short-coated Saints need weekly brushing. Both coat types shed heavily. Heavy drooling is a constant consideration. Annual grooming cost: $200–$500.

Bernese Mountain Dog

The Berner’s gorgeous tri-color coat requires brushing 2–3 times weekly to prevent matting, and daily during the two annual blowouts. Professional grooming every 6–8 weeks. Berners shed significantly year-round. Annual grooming cost: $300–$600.

Cost Comparison

Saint Bernard

Puppy: $1,500–$3,500. Annual care: $2,000–$4,000 (substantial food costs). Pet insurance: $60–$100/month.

Bernese Mountain Dog

Puppy: $2,000–$5,000. Annual care: $1,800–$3,500. Pet insurance: $70–$120/month (cancer risk makes this essential). Berners can be more expensive to purchase than Saints.

Which Is Right for You?

Choose a Saint Bernard if:

  • You want the largest, most laid-back giant breed
  • You want a dog with exceptional patience with small children
  • You prefer lower exercise requirements
  • You can manage heavy drooling

Choose a Bernese Mountain Dog if:

  • You want a slightly more active, versatile working dog
  • You love the tri-color coat and striking appearance
  • You want a breed with excellent trainability
  • You can handle the heartbreak of a short lifespan with proper insurance planning

Frequently Asked Questions

Q: Do Bernese Mountain Dogs really have shorter lifespans than Saints?

A: Both have short lifespans by dog standards. The Bernese Mountain Dog averages 7–10 years with cancer being the leading cause of death. Saint Bernards also average 8–10 years. The Berner’s extraordinarily high cancer rate (particularly histiocytic sarcoma) means many don’t reach 8 years. This is a well-documented and heartbreaking aspect of the breed.

Q: Which breed is better with children?

A: Both are exceptional family dogs. Saint Bernards may have a slight edge in pure patience — their extremely calm temperament and slow movements make them very safe around toddlers. Berners are equally gentle but slightly more playful and energetic.

Q: Do these breeds tolerate heat?

A: Neither tolerates heat well. Both were bred for alpine cold-weather work. In warm climates, both breeds need air conditioning, limited midday outdoor activity, and constant access to fresh water. Heat stroke is a genuine risk.

Q: How much do giant breeds eat?

A: A lot. A 160 lb Saint Bernard may eat 8–12 cups of quality dry food daily. A 100 lb Berner eats 5–8 cups daily. Annual food costs alone can exceed $1,500–$2,500 for these breeds depending on food quality.

Q: Are Saint Bernards or Berners easier to train?

A: Berners are typically easier to train — they are more food-motivated and handler-focused, with quicker response to positive reinforcement. Saints are trainable but more independent. Both breeds respond poorly to harsh correction and need patient, consistent training.

Nutrition and Feeding Comparison

Saint Bernard feeding considerations:

  • Very large breed — males 140–180 lbs requiring 6–10 cups daily
  • Giant breed puppy formula during the first 18–24 months
  • Multiple meals per day to reduce bloat risk
  • Long-coated Saints eat similar amounts to short-coated
  • Annual food cost: $1,200–$2,000

Bernese Mountain Dog feeding considerations:

  • Large breed — males 80–115 lbs requiring 4–6 cups daily
  • Giant/large breed puppy food during development (18–24 months)
  • Joint support through omega-3 rich foods is particularly important given cancer and dysplasia risks
  • Annual food cost: $900–$1,600

Living Together: Saint Bernard + Bernese Mountain Dog Households

Saint Bernards and Bernese Mountain Dogs are a natural pairing — both gentle Swiss giants with similar temperaments, cold-weather hardiness, and family-oriented personalities. They typically coexist beautifully. The practical management challenges are significant: two large, shedding dogs require substantial grooming investment and produce large amounts of hair, drool (particularly Saints), and food consumption. Both breeds can thrive together with adequate space, separate feeding stations, and enrichment activities like hiking and drafting.
