Temperament & Personality
The English Mastiff is the archetype of the "gentle giant". Despite its intimidating mass, it is calm, patient, and surprisingly gentle with children — although its size can be unintentionally dangerous. It is naturally protective but rarely aggressive without provocation. Its loyalty to the family is absolute and it can develop separation anxiety if left alone for too long.
