Boxer or Saint Bernard? On paper they differ most on exercise need, and on the scales Saint Bernard is the heavier at 120–180 lbs. Here is how the two compare on everything that shapes an ordinary week.
This is for someone already down to Boxer and Saint Bernard and deciding between them. For this pair the decision usually turns on exercise need and grooming need, so those are covered first and in most detail. Anyone choosing from a flat has a clear answer here: Boxer rates 2/5 against 1/5. There is no origin story here — only what changes about your week.
Between Boxer and Saint Bernard, exercise need is what separates them; neither is the lower-effort dog overall.
Choose Boxer if you do not want a standing grooming appointment, shedding is a problem in your house and you want a dog that picks up training quickly.
Choose Saint Bernard if your walking routine is modest.

The Saint Bernard is in a different weight class entirely — 120-180 lbs against the Boxer's 60-70, more than double, and classified as a giant breed against the Boxer's large. Height follows suit, 26-30 inches versus 21-25. This isn't a matchup of similar dogs; it's a comparison for someone deciding between big and enormous. Everything about daily life scales with that number, from the size of the crate you'll need to how much food goes in the bowl.
Despite the size gap, exercise need runs the opposite direction you'd expect: the Boxer rates very high (5/5), the Saint Bernard just low (2/5). Giant breeds like this one are famously low-key for their size, content with modest daily walks rather than sustained activity — a Saint Bernard that gets over-exercised, especially in heat, is a bigger health risk than one that gets too little.
The Boxer stays low-maintenance here at very low (1/5) grooming and moderate (3/5) shedding, while the Saint Bernard steps up to moderate (3/5) grooming and high (4/5) shedding — its double coat, whether short or long, comes out in volume. If fur management is a concern, this pairing tilts firmly toward the Boxer. Neither breed demands the constant trims a curly- or wiry-coated dog would, but the Saint Bernard's volume of loose fur is still something to plan around.
Neither dog belongs in a small apartment, but the Saint Bernard is the more extreme case — very low (1/5) apartment suitability against the Boxer's already-low 2/5. Barking favors the Saint Bernard though, low (2/5) against the Boxer's moderate (3/5); size, not noise, is what rules this breed out of compact living. A house with real square footage, not just a yard, is the baseline requirement for a dog that can weigh 180 lbs.
The Boxer trains more readily, high (4/5) against the Saint Bernard's moderate (3/5), though both land at moderate (3/5) for first-time-owner suitability and tolerate alone time about the same (moderate 3/5 for both). A Saint Bernard's sheer size means training matters just as much as with a more difficult breed — a large, undertrained dog is harder to manage regardless of temperament.
Both breeds score very high (5/5) with kids and high (4/5) with other dogs — a clean tie on family fit. The Saint Bernard is friendlier with strangers, rated high (4/5) against the Boxer's moderate (3/5), consistent with its reputation as a gentle, welcoming giant. Families that host frequently may find the Saint Bernard's easygoing manner with new faces the more convenient trait of the two.
Lifespan is short for both, and close: 7-10 years for the Boxer, 8-10 for the Saint Bernard — giant breeds simply don't get the extra years smaller dogs do. Hip and elbow dysplasia and bloat appear on both health lists, structural and digestive risks tied to large body size, while the Boxer adds cancer and heart disease, and the Saint Bernard adds dilated cardiomyopathy and entropion, an eyelid condition, to its own list.
The Saint Bernard is the pricier dog to keep — cost level very high (5/5) against the Boxer's high (4/5), with monthly costs of $150-310 versus $100-200 and first-year costs of $2,200-4,200 versus $1,500-3,000. Food volume alone for a dog that can weigh 180 lbs accounts for a meaningful share of that gap. Insurance premiums and vet visit pricing also tend to scale with a dog's weight, adding further to the Saint Bernard's higher ceiling.
Boxer weighs 60–70 lbs and lives 7–10 years; Saint Bernard weighs 120–180 lbs and lives 8–10 years. The two diverge most on exercise need, grooming need and energy level. They are level on tolerates being alone, good with other dogs and good for first-time owners, so those cannot decide it. Where the table declares a winner it means less work for the owner, nothing more; descriptive rows are left as ties on purpose. The value here is in the differences between the two columns; treat any single score as approximate.
Substantially — 120-180 lbs against 60-70, more than double, and it's classified as a giant breed rather than large. Expect a correspondingly bigger crate, bigger food bill, and bigger vet bills.
The Boxer, by a wide margin — very high (5/5) against the Saint Bernard's low (2/5). Giant breeds like the Saint Bernard are generally low-energy for their size.
The Saint Bernard, rated high (4/5) against the Boxer's moderate (3/5) — its double coat produces significant volume even though grooming need itself is only moderate (3/5).
The Saint Bernard runs $150-310 monthly and $2,200-4,200 in year one; the Boxer runs $100-200 and $1,500-3,000. Size drives most of that gap.
Yes — hip dysplasia, elbow dysplasia, and bloat appear on both lists, all tied to the physical stress of carrying a large frame.
Neither lives especially long — 7-10 years for the Boxer, 8-10 for the Saint Bernard, both short lifespans typical of large and giant breeds.
Both are, tied at very high (5/5) — a genuine strength for either breed if you have children in the house.
It depends heavily on space and exercise capacity: the Saint Bernard needs less activity (low, 2/5) but far more room, while the Boxer needs a real exercise routine (very high, 5/5) but takes up less space and less budget doing it.
Meaningful — $150-310 for the Saint Bernard against $100-200 for the Boxer, driven mostly by food volume.
Opposite ends of the scale — very high (5/5) for the Boxer, low (2/5) for the Saint Bernard, despite the size difference running the other way.
The Saint Bernard, marginally — 8-10 years against the Boxer's 7-10, though both are short-lived relative to smaller breeds.
