Bichon Frise vs Saint Bernard: Which Suits Your Home?

Few pairings on this site show a size gap as dramatic as this one: the Bichon Frise's 12–18 lbs and 9–12 inches against a Saint Bernard's 120–180 lbs and 26–30 inches — a giant breed that can outweigh the Bichon tenfold. Despite the scale difference, both share a double coat, though the Saint Bernard comes in either short or long variants versus the Bichon's uniformly curly, dense texture. This isn't a comparison of two similarly-sized dogs with different coats; it's a comparison between a lap-sized companion and one of the largest common breeds, with everything from doorways to car trunks to consider.

Surprisingly, exercise need ties at Low (2/5) for both breeds, and energy level ties too, Moderate (3/5) for the Bichon against Low (2/5) for the Saint Bernard — a Gentle, Patient giant that's genuinely more of a couch companion than its size suggests. Neither dog demands intense daily exertion, which makes the comparison less about activity level and more about the physical space and handling strength a 150-pound dog requires even at a calm pace, versus the Bichon's total lack of size-related management concerns.

Grooming need still favors the Saint Bernard on paper, Moderate (3/5) versus the Bichon's Very high (5/5), but shedding flips hard the other way — Very low (1/5) for the Bichon against High (4/5) for the Saint Bernard. A shedding Saint Bernard, given its sheer coat surface area, produces a genuinely large volume of loose hair even without the Bichon's need for frequent trims and detangling, so owners are trading a low-frequency, high-volume grooming task for a high-frequency, low-volume one.

This category shows the starkest gap in the entire comparison: Very high (5/5) apartment suitability for the Bichon against Very low (1/5) for the Saint Bernard — a giant breed that genuinely needs a house with room to stretch out, not a compact unit. Barking runs the opposite direction, Low (2/5) for the calm Saint Bernard versus Moderate (3/5) for the Bichon, and the Saint Bernard actually tolerates being alone better, Moderate (3/5) against the Bichon's Low (2/5), consistent with its Gentle, Watchful, low-drama temperament.

Trainability ties at Moderate (3/5) for both breeds, but first-time-owner suitability favors the Bichon, High (4/5) versus the Saint Bernard's Moderate (3/5) — not because the Saint Bernard is difficult-tempered, but because managing a Gentle giant still means managing genuine physical size and strength during training, especially leash work with a young, growing dog that will eventually weigh upward of 120 lbs. A first-time owner comfortable with that physical scale will find the Saint Bernard's Patient nature makes actual training sessions easier than the size alone might suggest.

Both breeds score well with families: the Saint Bernard actually edges ahead with kids, Very high (5/5) versus the Bichon's High (4/5), fitting its historic reputation as a Gentle, Friendly family companion, while good-with-other-dogs and friendliness-to-strangers both tie at High (4/5). The main household consideration isn't temperament but physical safety — a giant breed, however gentle, can accidentally knock over a small child or elderly visitor simply through size, something families should weigh alongside the excellent temperament scores.

The Bichon's 14–15 year lifespan more than doubles some estimates for the Saint Bernard's 8–10 years, a stark example of the inverse relationship between size and longevity in dogs. Both breeds carry five listed health concerns, but the Saint Bernard's — Hip Dysplasia, Elbow Dysplasia, Dilated Cardiomyopathy, Entropion, and Bloat (GDV) — are all conditions strongly associated with giant-breed size and deep-chested build, several of them life-threatening emergencies, while the Bichon's Skin Allergies, Patellar Luxation, Bladder Stones, Cataracts, and Dental Disease are typically manageable long-term issues.

Cost level jumps to Very high (5/5) for the Saint Bernard against Moderate (3/5) for the Bichon, and the figures show why: $150–$310 monthly and $2,200–$4,200 in year one for the Saint Bernard versus $80–$150 monthly and $1,100–$2,300 for the Bichon. A giant breed simply eats more, needs larger-dose medication and preventatives, requires oversized gear and furniture, and often carries higher costs for boarding, transport, and orthopedic or cardiac care over its shorter lifetime.
