The Bullmastiff combines courage and fearlessness with prudence and gentleness. He has a strong character, moderate temper, and is characterized by calmness and self-control. It is a sensitive dog, therefore it is not suitable for living in isolation. Although he likes to be close to the caregiver, he does not follow him step by step. He has the same affection for all household members and is ready to defend them at all costs. If he is properly brought up, he does not show dominant behavior towards the owner.
