A Newfoundland can weigh six to ten times what a Shetland Sheepdog does, 100-150 lbs versus 15-25 lbs, and stands roughly 13-15 inches taller. The Sheltie is essentially a scaled-down herding dog, agile and light on its feet, where the Newfoundland is built low-and-heavy for swimming and hauling. There is no ambiguity in this matchup: pick your size category first, because nothing else about these two breeds overlaps physically.
The Sheltie needs more exercise, High (4/5) versus Moderate (3/5) for the Newfoundland, and it carries that energy visibly, High (4/5) energy level against the Newfoundland's Low (2/5). Shelties were bred to herd and still want a job or a demanding routine; without one, that energy tends to come out as extra barking, which shows up elsewhere in this comparison.
Grooming ties at High (4/5) for both breeds, but shedding tilts slightly toward the Newfoundland being worse, Very High (5/5) versus High (4/5) for the Sheltie. Both have dense double coats that blow out seasonally, so neither is a low-hair-maintenance option regardless of the size difference between them.
This section has a real headline: barking. The Sheltie rates Very High (5/5) for barking against the Newfoundland's Low (2/5), one of the widest gaps on this entire page. Apartment suitability still favors the Sheltie overall, Moderate (3/5) versus the Newfoundland's Very Low (1/5), but if your walls are thin or your neighbors are close, the barking gap deserves more weight than the space question does.
The Sheltie rates High (4/5) for first-time owners against the Newfoundland's Moderate (3/5), and it edges out the Newfoundland on trainability too, Very High (5/5) versus High (4/5). Shelties are quick studies, often used in obedience and agility for exactly this reason, though that same intelligence means they need consistent engagement to avoid getting into their own trouble.
The Newfoundland leads with kids (Very High 5/5 versus High 4/5) and is far ahead with strangers (High 4/5 versus Low 2/5), Shelties tend to be reserved or even wary around unfamiliar people, a known trait of the herding-dog temperament. Both tie at High (4/5) with other dogs. If your household has a lot of visitors, the Newfoundland's openness with strangers is the more relevant number here.
The Sheltie is expected to live 12-14 years against the Newfoundland's 9-10, a real 2-5 year gap. What stands out more, though, is that the two health lists share nothing in common at all, the Sheltie's five conditions are a completely separate set from the Newfoundland's cardiac- and bloat-related risks. Whichever breed you choose, the vet conversations you will be having are entirely different ones.
The Newfoundland costs substantially more to keep: Very High (5/5) versus Moderate (3/5) for the Sheltie, $150-310 monthly versus $80-150, and $2,200-4,200 versus $1,100-2,300 in year one. That gap tracks directly with the size difference, more dog means more food, more medication by weight, and a bigger vet bill line item across the board.
Newfoundland weighs 100–150 lbs and lives 9–10 years; Shetland Sheepdog weighs 15–25 lbs and lives 12–14 years. The two diverge most on barking, energy level and apartment suitability and 2 other rated axes. They are level on good with other dogs and grooming need, so those cannot decide it. The table below marks a winner only where one breed is genuinely easier for a typical owner; size and origin are facts rather than merits and stay level. Ratings come from one source applied to both breeds, so they are meaningful against each other rather than as absolute scores.
A lot, the Newfoundland can weigh six to ten times as much (150 lbs vs 25 lbs) and stands well over a foot taller at the shoulder.
The Sheltie, by a wide margin, it rates Very High (5/5) for barking against the Newfoundland's Low (2/5). This is one of the largest gaps in the whole comparison.

No, none of the conditions on either list overlap. The Sheltie's risks are entirely separate from the Newfoundland's cardiac and bloat risks.
Significant, $80-150 monthly for the Sheltie versus $150-310 for the Newfoundland, and roughly half the first-year cost ($1,100-2,300 versus $2,200-4,200).
The Newfoundland, clearly, High (4/5) versus Low (2/5) for the Sheltie, which tends toward reserved or wary behavior around unfamiliar people, a common herding-breed trait.
