The majestic Neapolitan Mastiff is a noble and proud dog with a long history of serving mankind.  Bred to look meaner than it really is the Neapolitan is a gentle and faithful family dog.  But, it is also a protective dog suspicious of strangers and ready to defend the family and property.  This is a LARGE dog consuming close to 10 cups of food each day.  It should be firmly and consistently trained at an early age, and socialized into the human environment.  Consistent handling is also necessary to keep the dog focused on your demands and rules.  They are very good with children (females better than males), and males can be aggressive to other male canines.  Younger Mastiffs (and any large breed) should be carefully exercised to prevent damage to undeveloped bones and cartilage.  Adult dogs require daily, robust exercise.
