Newfoundlands are one of the gentlest and most water-loving giants in dogs. The breed was developed on the Newfoundland coast to work alongside fishermen, swim long distances, pull nets, and famously rescue people from the water. The modern Newfoundland is mostly a family pet but retains the calm temperament, strength, and swimming ability of its working ancestors. The breed asks for serious grooming, giant-breed budgeting, and emotional preparation for a relatively short lifespan. This guide is honest about all of it.
Newfoundland temperament
The classic Newfoundland profile:
- Gentle and patient. The breed is famously called the nanny dog. Most Newfoundlands tolerate handling, noise, and chaos calmly.
- Family-bonded. Deeply attached to the household. Many shadow their people room to room.
- Friendly with strangers. Unlike many guardian breeds, Newfoundlands typically greet new people warmly.
- Low-energy as adults. Plenty of sleep, plenty of leaning, plenty of resting against your legs.
- Sensitive. Despite the size, emotionally soft. Harsh corrections do not work.
- Water-driven. The breed loves swimming and often tries to “rescue” swimming family members by pulling them to shore.
- Drooly. Less than a Mastiff but more than most owners expect.
Newfoundlands are not high-drive working dogs in the way Border Collies or Malinois are. They are calm, present, family-centered giants.
Exercise needs
Plan for 30 to 60 minutes of moderate daily activity:
- Two walks of 20 to 30 minutes each.
- Weekly swim if water is accessible.
- Indoor mental work and short training sessions.
Exercise rules specific to the breed:
- No forced running until growth plates close (around 18 to 24 months).
- Heat is the breed’s worst enemy. The thick coat traps heat and the size limits cooling.
- Walk early morning and late evening in summer. Skip walks entirely on hot, humid days.
- Use ramps for cars and tall furniture.
- Stairs and slick floors are joint hazards in puppyhood.
Adult Newfoundlands are content with calm daily exercise. The combination of heat sensitivity and joint protection means they are not the breed for long summer hikes or running partners.
Swimming and water
The water work is part of the breed’s identity:
- Most Newfoundlands swim naturally and confidently from the first introduction.
- Pools, lakes, and gentle ocean access are all popular outlets.
- Watch for over-exhaustion. The coat retains water and adds significant weight.
- Rinse with fresh water after pool swims (chlorine) or ocean swims (salt).
- Dry the coat thoroughly after every swim. Trapped moisture causes hotspots.
Newfoundlands are also used in active water-rescue clubs and pulling sports (carting, drafting). The breed enjoys having a job.
Grooming
This is the most demanding part of Newfoundland ownership:
- Brushing 2 to 3 times weekly with an undercoat rake and slicker. Mats develop fast behind the ears and on the chest.
- Daily brushing during the two annual blow seasons (spring and fall).
- Bath every 6 to 8 weeks. The double coat takes hours to dry without a high-velocity dryer.
- Professional grooming every 8 to 10 weeks for owners who do not bathe at home.
- Nail trims every 3 to 4 weeks. Newfoundland nails are thick.
- Dental brushing several times weekly.
- Clean ears every 1 to 2 weeks.
- Trim feathering between the toes, around the ears, and on the rear.
Never shave a Newfoundland. The double coat insulates against heat and cold. Shaving disrupts regrowth and exposes skin to sunburn.
The grooming budget is significant. Owners who plan to outsource everything should expect $150 to $300 every 8 weeks at a giant-breed-capable groomer.
Common health issues
Reputable breeders screen for:
- Hip and elbow dysplasia: OFA evaluation of both parents.
- Subaortic stenosis (SAS): a cardiac condition with elevated rates in the breed. Cardiologist exam before breeding.
- Cystinuria: a urinary stone disorder. DNA test available.
- Eye conditions: annual OFA exams.
Common acquired issues:
- Bloat (gastric dilatation-volvulus): deep-chested giants are at high risk. Raised feeders, avoid heavy exercise around meals. Many owners pursue prophylactic gastropexy at spay or neuter.
- Cardiac disease: see SAS above.
- Cancer (especially osteosarcoma and hemangiosarcoma): elevated rates from middle age.
- Cruciate ligament tears.
- Hotspots and skin infections from trapped moisture in the coat.
- Heat intolerance and heatstroke.
Vet schedule:
- Puppy series through 16 weeks.
- Annual exams.
- Annual cardiac screening from age 3 (or as advised by your vet).
- Bloodwork yearly from age 5.
This is general information. A vet experienced with giant breeds drives the actual care plan.
Lifespan and cost
Typical lifespan is 8 to 10 years. Annual budget for one Newfoundland in 2026:
- Food: $1,000 to $1,600 (large adult, premium diet)
- Vet care: $700 to $1,200
- Insurance: $700 to $1,200
- Grooming (professional or supplies and dryer): $500 to $1,500
- Crate, beds, ramps, gear: $400 to $800
- Dental cleanings: $300 to $500 annualized
Total: $4,000 to $6,500 per year. Puppy from a reputable, health-tested breeder: $2,500 to $4,500. Rescue Newfoundlands are available through breed-specific rescues, often surrendered when families move or cannot manage the grooming workload.
Who should get a Newfoundland
Get one if:
- You have the space, vehicle, and budget for a giant breed.
- You can commit to 2 to 3 grooming sessions weekly and a professional groomer or home dryer.
- You accept a short lifespan and plan emotionally for it.
- You live somewhere temperate or have strong air conditioning.
- You want a calm, gentle, family-bonded giant.
Skip if:
- You hike or run long distances and want a sporting companion.
- You live somewhere extremely hot without air conditioning.
- You cannot tolerate drool or thick shedding.
- You cannot afford giant-breed food, vet, and grooming costs.
- You are uncomfortable with the grief of a 9-year average lifespan.
Newfoundlands are a deep emotional commitment in a short window of time. Owners who match the breed (calm households, temperate climates, willingness to groom) tend to adopt the breed again and again. Owners who chose the breed for the puppy photos often struggle with the grooming, the drool, or the heat. Pick honestly.
Frequently asked questions
How big do Newfoundlands get?+
Adult Newfoundland males typically reach 130 to 160 pounds, females 100 to 130 pounds. They are a giant breed and need the housing, vehicles, and budget that go with it. Plan accordingly before bringing one home.
Are Newfoundlands good with kids?+
Famously yes. The breed is gentle, patient, and protective with its own family's children. The risk is size. A 150-pound dog leaning on or stepping over a toddler can cause unintentional injury. Adult supervision is mandatory.
How long do Newfoundlands live?+
Typical lifespan is 8 to 10 years. Giant breeds do not live as long as smaller dogs. Cardiac disease (especially subaortic stenosis), cancer, and bloat are the leading causes of death. Annual cardiac screening matters.
How much grooming does a Newfoundland need?+
Significant. The thick double coat needs brushing 2 to 3 times weekly, with heavy shedding twice a year. Plan for professional grooming every 8 to 10 weeks or learn to bathe and dry the dog at home. Daily fold and ear checks add to the routine.
Do Newfoundlands actually like to swim?+
Yes. The breed was developed in Newfoundland to assist fishermen and pull in nets. Webbed feet, a water-resistant coat, and powerful swimming are still wired in. Most Newfoundlands love water from the first introduction.
