About the Neapolitan Mastiff

The Neapolitan Mastiff is an Italian guarding breed, kept around farms and estates in the south of the country and shaped for presence as much as for work. It is a giant dog, 61 to 79 cm and 49.9 to 68 kg, with heavy loose skin, deep wrinkles over the head and a rolling, deliberate walk. Temperament is watchful and quiet rather than reactive: strongly attached to its own household, indifferent or wary with strangers, and slow to move for anything it does not care about.

Energy is low and barking is rare, though none of that makes this an easy dog. It overheats quickly, so warm weather walks need real care, and puppies must be kept off stairs and away from jumps and rough wrestling while the joints form. Grooming is short coat simple, with the wrinkles and ears wiped and dried and a cloth kept to hand for drool. Ratings with children are moderate, and the sheer weight makes supervision essential. The mistake is skipping training, because a dog this size cannot be handled once it is grown.

What to expect at eight weeks

At eight weeks a Neapolitan Mastiff puppy is sleeping around 18 to 20 hours a day, is not house trained, and cannot hold on for more than an hour or two at a stretch. A giant breed puppy at eight weeks is already heavy and will keep growing for up to two years. Controlled growth matters more here than in any other size class, so a large breed specific puppy food and no overfeeding. Energy is on the lower side for the breed, but every eight week old puppy still runs in bursts and then crashes. Grooming is straightforward, but start handling the coat, feet and ears in week one anyway so it is never a fight later. The socialisation window is open and closing: everything it meets calmly now, from vacuum cleaners to men in hats, is easier for the rest of its life.
