Bullmastiffs have a very balanced character. They are not quickly impressed of something. They are courageous and physically strong. Although they are quite sensitive to moods in the house, they show themselves very gentle in their own families. They bark little and make their voices heard when there is danger. A Bullmastiff convincingly protects his family and possessions. They are happy at home surrounded by family.
