Neapolitan Mastiff

The Neapolitan Mastiff or Mastino / Mastini (Italian: Mastino Napoletano) is a large, ancient dog breed. This massive breed is often used as a guard and defender of family and property due to their protective instincts and their fearsome appearance.

Size and proportion

According to the American Kennel Club (AKC) standard, male Neapolitan Mastiffs should measure 26–31 inches (66–79 cm) at the withers, weigh 130–155 pounds (60-70 kg), while females should measure 24–29 inches (61–74 cm) and weigh 110–130 pounds (50–60 kg). Body length should be 10–15% greater than height.

Temperament

The Neapolitan Mastiff is fearless and extremely protective of its home and family. They prefer to be with their family. The Neapolitan Mastiff rarely barks unless under provocation, renowned for sneaking up on intruders as opposed to first alerting them of its presence.

Neapolitan Mastiffs, as a breed, are extremely intelligent dogs with a tendency to be independent thinkers. They learn quickly, which is both good and bad, since this guardian breed needs extensive proper socialization to learn to accept strangers, especially within the home; without proper early socialization and training, these dogs are likely to become aggressive towards strangers and unfamiliar dogs.
