Aggression, if it occurs, is typically due to poor socialisation or training. With proper upbringing, Mastiffs remain gentle and protective rather than aggressive.

Mastiffs have a calm, patient, and affectionate temperament. They are slow to respond but eager to please, known as gentle giants who are loyal and devoted. Mastiffs are generally good with other pets and children when socialised early, have low to moderate energy levels, and tend to be aloof with strangers, which makes them natural guardians.
