Neapolitan Mastiff – Neo Mastiff
Mostly the neapolitan mastiff have protective instincts toward strangers. The neapolitan mastiff need extensive exposure to friendly people so they learn to recognize the normal behaviors of “good guys.” Then the neapolitan mastiff can recognize the difference when someone acts abnormally.
Without careful socialization, the neo mastiff may be suspicious of everyone, which could lead to biting. Some Neapolitan Mastiffs go in the opposite direction — without enough socialization, they become fearful of strangers, which can lead to defensive biting.
