Behavior & Training of the Neapolitan Mastiff

The Neapolitan mastiff is a large, loving working class dog. The breed originated in Italy with the cross-breeding of British mastiffs and Roman molossus dogs. Neapolitans are watchful and loving pets, but they may not react well to other dogs in their home.

  1. Physical Traits

    • Neapolitans weigh up to 150 lbs. and can stand over 31 inches high. They may be black, gray, mahogany or tawny in color, with brindling or white patches. Smooth, short coats and wrinkled faces make this breed stand out.

    Temperament

    • These dogs are almost universally mellow and require only a minimal amount of exercise. They are easy to train, requiring only motivation and firmness, but training must be constant. They are intolerant of other dogs and strangers, so early socialization is key to avoid problems later in the dog's life.

    Needs

    • As very large dogs, Neapolitans require gentle exercise, preferring a leisurely stroll to a game of fetch. A large dog bed or even dedicated couch may be in order. These dogs also drool, which demands additional cleanup, but they need little grooming.

    Known Behaviors

    • While the Neapolitan is mild-mannered, the breed's size and power can make even minor behavioral problems disastrous. These dogs will lean against their loved ones, which is charming at 20 lbs. but dangerous at 140. They are also suspicious of strangers, and must be socialized to prevent barking and other threatening behaviors.

    Training Philosophy

    • This is not a pet for the meek. While not a fighting breed, the Neapolitan mastiff requires a firm hand. Daily training sessions and at least bi-weekly trips to the dog park are a necessity for a well-behaved mastiff. The AKC does not recommend this breed for first-time owners or families with small children.
