The Newfoundland is a giant Canadian working dog known for a patient temperament, powerful build, and water-resistant double coat. Adult males average about 28 inches at the shoulder and 130–150 pounds; females average about 26 inches and 100–120 pounds.
This can be a gentle family companion, but “gentle giant” does not mean effortless. Newfoundlands need early manners training, regular grooming, careful weight control, heat protection, and space for a very large dog—as well as readiness for shedding, drool, wet fur, and giant-breed care costs.

Newfoundland temperament
Newfoundlands are known for being devoted, sweet, patient, dignified, and generally willing to work with people. The breed’s history around fishing communities helped shape a strong, capable dog that is not necessarily intense or reactive.
Most well-socialized Newfoundlands enjoy close contact with their families. They are companion-oriented indoor dogs, not a good fit for being left isolated in a yard or kept outdoors only. They generally do best living with their people and participating in daily activities.
#1 Best Overall
Their size changes the practical stakes of ordinary puppy behavior. A jumping puppy may be manageable at 20 pounds but difficult to control at adult size. Address jumping, counter-surfing, pulling, grabbing objects, and rushing through doors early.
Are Newfoundlands good with children?
They can be excellent family dogs, but no Newfoundland is a built-in babysitter. “Nanny dog” is breed folklore, not a caregiving role. A friendly giant can accidentally knock a child over, and any dog may react if frightened, hurt, disturbed while eating, or unable to escape unwanted handling. Never leave a child alone with a dog, regardless of breed or past behavior.
- Supervise every interaction between young children and the dog.
- Teach children not to climb on, hug tightly, tease, hit, disturb while eating, or take items from the dog.
- Give the dog a quiet resting area where children cannot bother it.
- Do not let a child walk a powerful adult Newfoundland alone.
Introduce other dogs and pets gradually and monitor interactions. Early socialization and reward-based puppy training are especially important.
History and working purpose
The Newfoundland developed on the island of Newfoundland in Canada, where it served fishing communities as a versatile working dog. Its jobs included pulling carts, hauling loads, assisting fishermen, and water rescue and other water-related work.
The breed’s structure reflects those tasks: substantial strength, powerful hindquarters, webbed feet, a broad tail that can act as a swimming rudder, and a dense coat suited to cold water. The FCI standard classifies the Newfoundland as a heavy-load sled dog and a water dog.
The American Kennel Club recognized the Newfoundland in 1886. The Newfoundland Club of America, the AKC parent club in the United States, was founded in 1930.
Newfoundland size and appearance
This is a very large, heavy-boned dog with a broad, powerful body. Large size is part of the breed, but the biggest possible dog is not automatically the best dog. Breed organizations emphasize balance, soundness, structural power, and correct movement over extreme size.

A sound, well-proportioned Newfoundland is preferable to an unusually oversized one.
Coat, shedding, and grooming
Newfoundlands have a water-resistant double coat with a moderately long, coarse outer coat and a soft, dense undercoat. The legs are feathered, the tail is heavily coated, and the hair is shorter and finer on the head, muzzle, and ears. The undercoat is generally denser in winter but remains present to some degree year-round.
Expect substantial shedding. Many Newfoundlands shed especially heavily during seasonal coat changes, commonly twice a year. Spayed and neutered dogs may shed year-round and need brushing several times each week.
A practical grooming routine
- Brush thoroughly at least weekly, working through the coat rather than just smoothing the surface.
- Brush more often during seasonal shedding.
- Use a slicker brush and long-toothed comb to reach the undercoat.
- Check behind the ears, under the legs, around the collar, and near the tail for mats.
- Trim nails regularly and check the ears routinely.
- Bathe when necessary and dry the coat completely afterward.
Professional grooming may be worthwhile because of the dog’s size and coat volume. Teach a Newfoundland to tolerate paw handling, brushing, bathing, dryers, and examination.

Should you shave a Newfoundland for summer?
Routine shaving is not a sound heat-management strategy. The double coat provides environmental protection, and removing the outer coat can alter that protection and expose the skin to sun and irritation. The FCI standard discourages trimming and scissoring. Limited sanitary or medical trimming may be appropriate when recommended by a veterinarian or professional groomer.
Newfoundlands are not hypoallergenic. They shed heavily, and allergies can involve dander, saliva, or other allergens—not just loose hair.
Exercise and swimming
A healthy adult Newfoundland needs at least 30 minutes of moderate exercise daily, according to the AKC. Many enjoy longer walks, hiking, swimming, retrieving, obedience, rally, tracking, agility, drafting, and carting when properly conditioned.
A balanced routine might include:
- A moderate daily walk
- Short reward-based training sessions
- Controlled retrieving or tug games
- Scent games and food puzzles
- Swimming in a safe, supervised setting
- Draft or cart work after suitable training and conditioning
Swimming is optional. The Newfoundland is adapted to water, but not every individual wants to swim, and some never do. Never push a dog into water or assume it can swim safely without observing it in a controlled environment.

Puppies have developing bones and joints. Avoid forced-distance exercise, repetitive jumping, hard-surface running, and strenuous conditioning until the dog is mature and your veterinarian confirms the activity is appropriate. Let age, gait, body condition, and orthopedic health guide exercise.
Heat safety
A dense coat and large body make heat management important. Exercise during cooler parts of the day, provide shade and fresh water, and avoid strenuous activity in hot or humid conditions. Shaving is not a substitute for these precautions.
Heavy panting, vomiting, excessive drooling, distress, uncoordinated movement, collapse, or unconsciousness can indicate a heat emergency. Move the dog away from the heat and seek immediate veterinary help.
Training and socialization
Newfoundlands are generally intelligent and responsive to calm, consistent instruction. They tend to learn best with praise, food rewards, and patient guidance rather than harsh corrections. Start puppy training and socialization early, before the dog’s size makes handling difficult.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Prioritize these skills:
- Loose-leash walking
- Reliable recall
- Sit, down, stay, and leave-it
- Polite greetings without jumping
- Waiting at doors and around food
- Handling for grooming and veterinary care
- Calm car travel
- Safe behavior around children, dogs, and other animals
- Emergency cues such as “come,” “drop,” and “wait”
Short sessions repeated regularly are more useful than occasional exhausting lessons. Include calm social exposure to people, surfaces, sounds, vehicles, grooming equipment, and veterinary handling.
Newfoundland health concerns
Like other giant breeds, Newfoundlands can be affected by orthopedic, cardiac, urinary, gastrointestinal, skin, ear, and thyroid problems. Important concerns include hip dysplasia, elbow dysplasia, cardiac disease such as subvalvular aortic stenosis, cystinuria, gastric dilatation-volvulus (GDV), ear infections, hot spots, skin disease, and thyroid disease.
The Newfoundland Club of America identifies these core health clearances for breeding dogs:
| Area | Recommended documentation |
|---|---|
| Hips | Radiographs submitted to the Orthopedic Foundation for Animals (OFA) |
| Elbows | Radiographs submitted to OFA |
| Heart | Auscultation or echocardiography by a board-certified cardiologist |
| Cystinuria | DNA testing by blood or cheek swab |
Additional recommended testing includes an eye examination, patella palpation, and thyroid blood testing. Health testing reduces risk but cannot guarantee a puppy will remain free of disease.
Cystinuria
Cystinuria is an inherited disorder that can lead to cystine crystals or stones in the urinary tract. Ask a breeder for the relevant DNA results or documented genetic status of both parents.
Bloat and GDV
Gastric dilatation-volvulus, commonly called bloat with torsion, is a life-threatening emergency. Signs may include restlessness, distress, excessive salivation, repeated unproductive retching, breathing difficulty, abdominal enlargement, and collapse.
Seek immediate veterinary treatment if GDV is suspected. Ask your veterinarian about meal scheduling, exercise after meals, individual risk factors, and whether preventive gastropexy should be discussed.
Feeding and weight management
Feed a complete and balanced diet appropriate for the dog’s life stage and maintain a lean, healthy body condition. Growing Newfoundlands may need a diet formulated for giant-breed puppies, so discuss food and growth with your veterinarian. Unrestricted feeding and excess weight can increase health risks.
- Measure meals instead of estimating portions.
- Adjust food for body condition, activity, age, growth, and the food’s calorie density.
- Count treats and training rewards as part of daily calories.
- Divide meals as recommended by your veterinarian.
- Avoid vigorous exercise immediately after a large meal.
- Keep fresh water available.
There is no dependable universal cup-per-day amount for this breed. Requirements vary with metabolism, activity, age, growth, reproductive status, food energy density, and body condition. A lean, healthy body matters more than reaching a particular number on the scale.
Is a Newfoundland suitable for your home?
A Newfoundland can live in different types of homes if its physical, social, grooming, and exercise needs are met. A yard can help, but it does not replace walks, training, enrichment, or time with people.
Before bringing one home, consider:
- Whether doorways and hallways can accommodate a giant dog
- Whether your vehicle can safely transport the dog
- Whether floors provide enough traction
- Where a large crate, bed, and food containers will go
- Whether you can afford giant-breed veterinary and grooming costs
- How you will manage shedding, drool, muddy feet, and wet fur
- Whether your climate has hot or humid conditions
- Whether a veterinarian experienced with giant breeds is accessible
A backyard, kennel, tie-out, or chain does not meet the breed’s social needs. Newfoundlands should not be tied out or chained.

A CHIC number does not mean every health result was normal. It confirms required tests were completed and made publicly available. Membership in a breed club is useful but is not, by itself, proof that a breeder or litter meets responsible-breeding standards.
Newfoundland colors
Under the American breed standard, accepted colors are black, white-and-black, gray, and brown or bronze. AKC registration descriptions also include beige and black-and-tan; a registry description does not necessarily mean a color is accepted or preferred for conformation showing. Standards and registry descriptions differ between countries.
Be cautious when a seller markets “champagne,” black-and-tan, or another unusual color as rare, superior, or automatically more valuable. Color should not replace health testing, sound structure, temperament, and responsible breeding.

The Bottom Line
The Newfoundland suits owners who want a people-oriented working dog and are prepared for giant-breed responsibilities. Its gentle temperament is real, but ownership still means daily exercise, extensive grooming, careful feeding, heat protection, early training, child supervision, and meaningful health-record checks before buying a puppy.
