Bernese Mountain Dog

Temperament

Calm, gentle, devoted, slightly aloof with strangers. Berners adore their family, are wonderful with children of all ages and tolerant of other pets.

Exercise

60 minutes of moderate daily exercise. Heavy build means avoiding impact in puppies under 18 months — no jogging, jumping, long stairs.

Grooming

Long, silky double coat. Brush 3× weekly, daily during seasonal moults. Bathe every 6–8 weeks. Light trimming around feet and rear keeps things tidy.

Health

Cancer is the leading cause of death — over 50% in some studies. Hip and elbow dysplasia. Bloat / GDV. Histiocytic sarcoma is over-represented in this breed. Lifespan 7–10 years; planning for shorter time together is part of choosing this breed.
