Great Danes aren't Danish. They were developed in Germany as boar-hunting dogs — massive, fast, and powerful enough to pin wild boar until hunters arrived. Newfoundlands were developed on the island of Newfoundland as working water dogs, hauling fishing nets, pulling carts, and performing water rescues in the frigid North Atlantic. One was bred to chase down large game on land. The other was bred to save drowning people at sea. Both ended up as gentle giants that think they're lap dogs.
These two sit at opposite ends of the giant breed spectrum in many ways. The full comparison framework is in the breed comparisons guide.
Size and Build
| Trait | Great Dane | Newfoundland |
|---|---|---|
| Height (male) | 76–86 cm | 69–74 cm |
| Height (female) | 71–81 cm | 63–69 cm |
| Weight (male) | 54–90 kg | 59–68 kg |
| Weight (female) | 45–59 kg | 45–54 kg |
| Build | Tall, lean, elegant | Broad, heavy, powerful |
The Dane is taller — one of the tallest breeds in existence. But the Newfoundland can match or exceed the Dane in weight despite being shorter. The Dane is vertical; the Newfie is horizontal. Different spatial challenges: the Dane's head clears kitchen counters while the Newfie needs floor space for a body that takes up the square footage of a small couch.
Temperament
Great Danes are gentle, affectionate, and surprisingly dependent on human company for a dog that could physically overpower most people. They're calm indoors, good with children, and generally sociable with other dogs. Despite their imposing size, they're sensitive — harsh corrections affect them deeply.
Newfoundlands are equally gentle but with a more patient, stoic quality. They're famously good with children — "nanny dog" is an informal label the breed has earned through centuries of family temperament. Newfies are less reactive than Danes and handle chaos with remarkable composure. They're also more independent, comfortable making decisions (a trait from their working heritage), and devoted without being clingy.
Both breeds are poor guard dogs in practice. They may bark at strangers, but their default response to most people is warmth.
Grooming
This is a significant differentiator.
Great Danes have short, smooth coats. Weekly brushing, occasional baths. Grooming is minimal. The tradeoff: they drool. Some Danes drool heavily, especially after drinking or when excited. Keep towels handy.
Newfoundlands have a thick, dense double coat that requires brushing three to four times per week to prevent matting. During seasonal coat blows, daily brushing is necessary and produces staggering volumes of loose fur. They also drool — heavily. A Newfoundland in your home means fur everywhere and drool on everything. Both messes are constant.
Health
| Health Factor | Great Dane | Newfoundland |
|---|---|---|
| Top concern | Bloat (GDV), DCM | Subaortic stenosis, hip dysplasia |
| Lifespan | 7–10 years | 8–10 years |
| Heart disease | Dilated cardiomyopathy | Subaortic stenosis (congenital) |
| Joint issues | Hip dysplasia, wobbler syndrome | Hip/elbow dysplasia, cruciate tears |
| Bloat risk | Very high | High |
| Cancer risk | Osteosarcoma (high) | Moderate |
Both breeds have short lifespans — the defining heartbreak of giant breed ownership. Great Danes have one of the shortest average lifespans of any breed, with many not reaching age 8. Bloat is a life-threatening emergency that strikes disproportionately in deep-chested breeds, and the Great Dane sits at the top of that risk list.
Newfoundlands face a high incidence of subaortic stenosis, a congenital heart condition. Cardiac screening of breeding stock is essential but doesn't eliminate the risk entirely. Cystinuria (a kidney stone condition) is also breed-specific.
Exercise
Great Danes need 45 to 60 minutes of moderate daily exercise. They're not endurance athletes — their build is designed for short bursts of power, not sustained effort. Long walks and moderate play sessions suit them. Avoid forced running, particularly on hard surfaces, as their joints are vulnerable.
Newfoundlands need similar duration but ideally with access to swimming. Swimming is the perfect exercise for Newfies — it's their element, and it's low-impact on joints that bear enormous weight. On land, moderate walks work, but this breed overheats quickly in warm weather.
Which Fits Your Life?
Choose the Great Dane if you have the vertical space (doorways, vehicles), want a short-coated giant that's low-maintenance on grooming, and can absorb the emotional reality of a likely 7-to-10-year lifespan. Danes fit surprisingly well in large apartments because they're calm indoors.
Choose the Newfoundland if you have access to water, can commit to serious coat maintenance, live in a cooler climate, and want a giant breed with a patient, unflappable temperament. Newfies are the better choice for households with young children.
