Newfoundland or Rottweiler? On paper they differ most on grooming need, and on the scales Newfoundland is the heavier at 100–150 lbs. Here is how the two compare on everything that shapes an ordinary week.
This is for someone already down to Newfoundland and Rottweiler and deciding between them. For this pair the decision usually turns on grooming need and energy level, so those are covered first and in most detail. Anyone choosing from a flat has a clear answer here: Rottweiler rates 2/5 against 1/5. There is no origin story here — only what changes about your week.
Between Newfoundland and Rottweiler, grooming need is what separates them; neither is the lower-effort dog overall.
Choose Newfoundland if this is your first dog, your walking routine is modest and the dog will be alone during the working day.
Choose Rottweiler if you do not want a standing grooming appointment, shedding is a problem in your house and a smaller dog suits your car, your home or your back.

The Newfoundland outweighs the Rottweiler at the top end (150 lbs vs 135 lbs) but the ranges overlap significantly, a big Rottweiler and a smaller Newfoundland can land at similar weights. Height is nearly identical too, 26-28 in versus 22-27 in. The real difference is build: the Newfoundland is bulkier and built for water, the Rottweiler is denser muscle built for work and guarding.
The Rottweiler wants more from you physically, High (4/5) exercise need and High (4/5) energy level against the Newfoundland's Moderate (3/5) and Low (2/5). That is a real daily-life difference: the Rottweiler needs a job or a serious exercise routine, while the Newfoundland is satisfied with steady, unhurried activity. If you are not planning structured exercise most days, the Newfoundland is the easier fit.
Grooming flips the expected pattern, the Newfoundland needs High (4/5) grooming attention for its double coat, while the Rottweiler needs just Low (2/5). Shedding still favors the Rottweiler somewhat, High (4/5) versus the Newfoundland's Very High (5/5), but both will leave hair on your furniture year-round. Budget serious brushing time for the Newfoundland specifically around its twice-yearly coat blow.
Both breeds score poorly for apartment life, Very Low (1/5) for the Newfoundland, Low (2/5) for the Rottweiler, so this is not really a contest, just two different flavors of no. Barking runs Low (2/5) for the Newfoundland and Moderate (3/5) for the Rottweiler. Both tolerate alone time only moderately at best (3/5 and 2/5), so neither is suited to long solo days regardless of housing.
The Newfoundland rates Moderate (3/5) for first-time owners while the Rottweiler drops to Low (2/5), its strength, protective instincts, and size make it a breed better suited to someone with prior large-dog experience. Trainability itself ties at High (4/5) for both, so it is not that the Rottweiler is harder to teach, it is that mistakes with an undertrained Rottweiler carry higher stakes than with a Newfoundland.
The Newfoundland outperforms the Rottweiler on every social measure here: kids (5/5 vs 4/5), other dogs (4/5 vs 3/5), and strangers (4/5 vs 2/5). The Rottweiler's Low (2/5) rating with strangers reflects its guarding instincts rather than aggression, but it means more work socializing the dog and managing visitors. If you host often or have a busy front door, that gap matters more than the size numbers do.
Both breeds land at 8-11 years, effectively tied. Health is where they truly diverge, the Newfoundland's five known conditions include subaortic stenosis and cystinuria, while the Rottweiler's list runs to ten and includes cancer, heart disease, arthritis, and bone cancer specifically. The two share hip dysplasia and bloat risk, both worth managing with a slow-feed bowl and a lean body condition, but the Rottweiler's broader risk list is worth discussing with a breeder about lineage.
The Newfoundland costs a bit more to keep, Very High (5/5) versus High (4/5) for the Rottweiler, and the dollar ranges track that: $150-310 monthly versus $125-250, and $2,200-4,200 versus $2,000-3,500 in year one. The gap is modest rather than dramatic, mostly driven by the larger dog's bigger food bill and heavier grooming needs.
Newfoundland weighs 100–150 lbs and lives 9–10 years; Rottweiler weighs 80–135 lbs and lives 8–11 years. The two diverge most on grooming need, energy level and friendly to strangers. Almost every rated axis separates them at least slightly. 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.
At the top of the range, yes, up to 150 lbs versus 135 lbs, but the weight ranges overlap heavily, and height is nearly the same (26-28 in vs 22-27 in). Build differs more than raw size: the Rottweiler is denser muscle, the Newfoundland is bulkier and less compact.
The Rottweiler, clearly, High (4/5) exercise need and High (4/5) energy versus the Newfoundland's Moderate (3/5) and Low (2/5). The Rottweiler does better with a job or structured routine than the calmer Newfoundland.
The Newfoundland is the safer pick at Moderate (3/5) versus the Rottweiler's Low (2/5). The Rottweiler's strength and protective instincts mean mistakes in training or socialization carry more consequence.
Very differently. The Newfoundland rates High (4/5) friendliness to strangers; the Rottweiler rates Low (2/5), reflecting its guarding instincts. If you host often, budget extra time for the Rottweiler's socialization.
$150-310 for the Newfoundland, $125-250 for the Rottweiler, a modest gap rather than a dramatic one, with first-year costs at $2,200-4,200 versus $2,000-3,500.
Yes, hip dysplasia and bloat show up on both lists. Beyond that the Rottweiler carries a notably longer risk list of ten conditions including cancer, heart disease, and arthritis, against the Newfoundland's five.
Pick the Newfoundland for a calmer, more stranger-friendly giant that is easier for a first-time owner; pick the Rottweiler if you want a more athletic, protective dog and have prior large-breed experience.
$150-310 for the Newfoundland, $125-250 for the Rottweiler.
The Rottweiler, rated High (4/5) versus the Newfoundland's Moderate (3/5).
