The Neapolitan Mastiff is fearless and extremely protective of its home and family. They prefer to be with their family and to remain in and around the home always. They are not a dog to go and wander off.
As a guardian breed, they are very wary of strangers, but usually if seeing that their master is relaxed, will soon accept them. The Neapolitan Mastiff rarely barks unless under provocation, renowned for sneaking upon intruders as opposed to alerting them of their presence first.
