Temperament & character

The Newfoundland is calm, patient, and remarkably gentle, especially with children. It shows little aggression and is usually friendly toward strangers.

Exercise & stimulation

Despite its size, moderate walks and especially swimming are enough, since the Newfoundland has a natural affinity for water. Excessive strain on the joints during growth should be avoided.

Grooming

The dense, water-repellent double coat needs brushing several times a week, daily during shedding. Given the breed's size, the time and physical effort required for grooming should not be underestimated.

Suitable for beginners?

Because of its size, grooming demands, and potential health risks, the Newfoundland is not particularly suited to beginners. Experience with giant breeds and adequate space make keeping one considerably easier.

Health & common problems

Breed-typical conditions include hip dysplasia, subvalvular aortic stenosis as a congenital heart defect, and, due to its deep chest, a risk of gastric torsion. As a giant breed, the Newfoundland benefits from slow, controlled puppy growth to protect the joints.

Good with: Families with space, proximity to water
