Newfoundland

Temperament

Sweet, calm, patient, loyal. Newfoundlands bond closely with their family, are remarkably tolerant with children of all ages, and tend to get along with other animals.

Exercise

45–60 minutes of moderate daily exercise. Swimming is ideal — they're built for it (webbed feet, water-repellent coat). Avoid impact exercise in puppies.

Grooming

Heavy double coat — brush 3–4× weekly, daily during seasonal moults. Bathe every 6–8 weeks. Drool is significant.

Health

Cardiomyopathy / aortic stenosis. Hip dysplasia. Cystinuria (DNA test). Bloat / GDV. Lifespan averages just 9–10 years.
