Why this guide

If you’re choosing between a Bernese Mountain Dog and a Saint Bernard, you’re looking at two classic “gentle giant” breeds. Both are affectionate, family-oriented dogs with big hearts — but they differ in size, typical health problems, grooming needs, and how well they fit different homes and routines. This guide compares the breeds side-by-side and helps you decide which better matches your lifestyle.

Head-to-head: key factors

Temperament

Both breeds thrive on human companionship and are poor choices for owners who plan to leave a dog alone for many hours daily.

Exercise and activity needs

In hot weather both breeds are heat-sensitive: exercise in cooler parts of the day and watch for overheating.

Grooming and maintenance

Grooming time: Bernese typically require more brushing time per week; Saint Bernards require more attention to facial folds and drool cleanup.

Health: common issues & lifespan

- Bernese Mountain Dog: Median lifespan is shorter than many breeds — commonly reported as 6–8 years. The breed has a high incidence of malignant cancers, which is the leading cause of death in Bernese populations [(Bernese Mountain Dog Club of America)](https://bmdca.org) and veterinary studies. - Saint Bernard: Typically 8–10 years, though large-size related illnesses can shorten life expectancy for individuals.

- Bernese Mountain Dog: High risk of cancer (including histiocytic sarcoma, lymphoma, mast cell tumors), hip and elbow dysplasia, degenerative myelopathy, patellar luxation, and bloat (GDV). Responsible breeders test for hip/elbow scores and screen for known genetic issues. - Saint Bernard: Hip and elbow dysplasia, elbow dysplasia, osteosarcoma, entropion/ectropion (eyelid abnormalities), dilated cardiomyopathy, and bloat (GDV). Their large frame predisposes them to joint and orthopedic problems.

- For both breeds, check OFA/health clearances (hips, elbows, heart, eyes) and breeder health records before buying a puppy [(OFA)](https://www.ofa.org). Consider pet insurance early because large-breed medical bills (orthopedics, cancer care) can be high.

Pros and Cons

Bernese Mountain Dog

- Affectionate, people-oriented, great family dog - Good for active families who enjoy hiking or outdoor work - Strong reputation for patience with children when socialized - Shorter median lifespan (high cancer risk) - Heavy shedding and higher grooming time - Not great for very hot climates or very small homes

Saint Bernard

- Extremely gentle, patient, and family-friendly - Very tolerant with children; often described as “nanny dogs” - Lower energy for a giant breed — good for calmer households - Very large — needs space and strong handling; potential for accidental injury to small children - Heavy food and veterinary costs; drooling and facial fold maintenance - Prone to serious orthopedic and cardiac issues

Choosing a breeder or rescue

Practical tips before you commit

Key Takeaways


If you’re deciding between the two, meeting dogs of both breeds, talking to breeders and rescue volunteers, and discussing health-clearance records will give the clearest picture of the lifelong commitment required. Neither breed is “better” — the right choice is the one that fits your home, activity level, finances, and tolerance for grooming and health care.

Frequently Asked Questions

Which breed sheds more?

Bernese Mountain Dogs shed more overall, especially during seasonal blowouts, because of their long double coat. Saint Bernards shed too but generally have a shorter, dense coat and slightly less profuse long-term shedding.

Are these breeds good with children?

Yes — both breeds are known for being patient and affectionate with children when properly socialized and supervised. Saint Bernards’ large size makes supervision important around very small children to avoid accidental knocks.

How much exercise do they need daily?

Both breeds do well with about 30–60 minutes of low-to-moderate exercise per day. Avoid high-impact or very long-distance exercise, especially while they’re growing, to protect joints.

Which breed lives longer?

On average, Saint Bernards live a bit longer (commonly 8–10 years) than Bernese Mountain Dogs (commonly 6–8 years), though individual lifespans vary widely with genetics and care.
