Which breed of dog is this?
The Neapolitan Mastiff or Mastino ('Mastino Napoletano') is a large dog breed from Italy. This massive breed is often used as a guard and defender of family and property due to their protective instincts and their fearsome appearance.
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).
The Neapolitan Mastiff is large and powerful. Their bodies are covered in loose skin with a coat that can either be black, blue, mahogany or tawny. 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.
Neapolitans must be well socialized with people, as they are large, powerful dogs and do not always know their own strength. Neapolitans will be wary of strangers and protective of their family, which can be disastrous for small children. Most of the time, they will protect their owners with their lives.
