Deep dive
Size and build
A Saint Bernard is a genuinely giant dog, 120 to 180 pounds and 26 to 30 inches at the shoulder, against the Border Collie's medium 30-to-55-pound frame. At the upper end, a Saint Bernard can outweigh a Border Collie by more than 150 pounds, one of the largest size gaps in any comparison on this site.
Energy and exercise
Exercise need drops sharply for the Saint Bernard, rated low (2/5) against the Border Collie's very high (5/5), a giant breed with a famously calm, low-drive temperament. Its bulk actually works against high activity; this is not a dog built for long runs, whatever its size might suggest.
Grooming and shedding
Grooming ties at moderate (3/5) for both breeds, but shedding favors the Border Collie, moderate (3/5) against the Saint Bernard's high (4/5), a lot more coat to shed on a dog this large, even at a similar grooming-effort rating.
Apartment living, noise and time alone
Apartment suitability ties, and not in either breed's favor, very low (1/5) for both. A Saint Bernard's size alone rules out most small spaces regardless of its low exercise need; it does bark less, though, rated low (2/5) against the Border Collie's moderate (3/5).
Training and owner experience
Trainability favors the Border Collie clearly, 5/5 against the Saint Bernard's moderate (3/5), a famously gentle breed, but not an especially quick study. First-time-owner suitability flips, though: moderate (3/5) for the Saint Bernard against very low (1/5) for the Border Collie, since its temperament is far more forgiving even if its size demands its own kind of preparation.
Kids, other dogs and visitors
The Saint Bernard rates very high (5/5) with kids against the Border Collie's high (4/5), and higher with strangers too, high (4/5) versus moderate (3/5), its temperament profile of gentle, patient, and friendly shows up directly here. The two tie on getting along with other dogs, both at 4/5.
Health and lifespan
This pairing has the shortest lifespan in this batch: Saint Bernard at 8 to 10 years against the Border Collie's 12 to 15, a gap of up to seven years. Hip dysplasia is the only shared condition between their health lists. The Saint Bernard's remaining risks, elbow dysplasia, dilated cardiomyopathy, bloat, are largely giant-breed problems the Border Collie's medium frame does not carry.
Cost to keep
Cost level rates very high (5/5) for the Saint Bernard against moderate (3/5) for the Border Collie, the widest cost gap in this comparison set. Monthly spend runs $150 to 310 against $100 to 180, and first-year costs reach $2,200 to 4,200 versus $1,500 to 2,800. Feeding and vet care both scale with size, and it shows clearly here.
Border Collie vs Saint Bernard at a glance

They are level on apartment suitability, good with other dogs and grooming need, so those cannot decide it. The comparison marks an easier option only where one exists. Facts like weight and country of origin are not scored. Both dogs are rated from the same dataset, which is what makes the numbers comparable with each other even though any individual dog sits somewhere inside its breed's range.
