Bullmastiff: the silent guardian

The Bullmastiff is an imposing English dog from the cross of Bulldog and Mastiff. Calm, brave and deeply attached to its family, it is a born guardian with a surprisingly gentle temperament at home.

Origins of the Bullmastiff

Developed in England in the 19th century, it was used by gamekeepers to pin down poachers without injuring them. Officially recognised in 1924.

Temperament and personality

The Bullmastiff is known for:

  • A calm and composed temperament
  • Strong courage and protective instinct
  • Great gentleness with its family
  • Natural reserve with strangers

It rarely barks but acts with determination if needed.

Training and socialization

Intelligent but stubborn, it needs firm, consistent and kind training from an early age. Early socialization is essential to channel its guard instinct.

Health and care

The Bullmastiff has several predispositions:

  • Hip and elbow dysplasia
  • Gastric torsion
  • Heart conditions
  • Cancers (lymphoma, osteosarcoma)
  • Short life expectancy (8-10 years)

Its short coat needs little care (weekly brushing). Heat sensitive (brachycephalic face).

The Bullmastiff in the family

In a calm and experienced family, it is a gentle and protective companion. Good tolerance with the family’s children (under supervision, due to size).
