Temperament

Bernese Mountain Dog: The Bernese Mountain Dog is a majestic and loyal breed known for their calm demeanour and protective instincts. They form deep bonds with their families and are surprisingly gentle for their size. They are not high-energy dogs but do need regular exercise and mental stimulation. An experienced owner who can provide consistent leadership is ideal.

Pyrenean Mastiff: Pyrenean Mastiff dogs are gentle giants — calm, patient, and devoted to their families. Despite their imposing size, they are often surprisingly gentle with children. They have a protective nature but are not typically aggressive. They need space and are best suited to homes with large gardens.

Exercise Needs

Bernese Mountain Dog: Bernese Mountain Dog dogs need regular moderate exercise — about 1 hour daily through walks and gentle play. Despite their size, they should not be over-exercised, especially as puppies, as this can damage developing joints and bones. Avoid strenuous activity in hot weather as large dogs overheat easily. Swimming is an excellent low-impact exercise option.
