History of Neapolitan Mastiffs

Mastiffs are thought to have been developed over 5,000 years ago in Tibet where they were used as guard dogs and in battle. The Neapolitan Mastiff was developed in Naples in Italy and the breeding was focussed on producing a large, loyal, loving dog with a smooth coat and loose skin that would prevent injury in an attack. The Neapolitan Mastiff (also referred to as the Mastino or Neo) almost went extinct around World War II but after the breed was exhibited at a dog show in Naples in 1946 they were reintroduced to the public. A journalist had seen the breed at the show and had taken a great interest, playing an important role in building the Neo’s popularity back up. A couple of years later in 1948 a breed standard was written for them and by the early 1970s they had gained popularity in Europe and further afield. The United States Neapolitan Mastiff Club formed in 1991 and in 2004 the breed was recognised by the American Kennel Club. These days the Neapolitan Mastiff is a loyal companion, they are mostly family pets but are also used in shows. Despite not being used as guard dogs anymore, they remain very protective.  


The Neapolitan Mastiff is an impressive dog, characterised by their loose skin and the hanging wrinkles on their heads. Neapolitan Mastiffs are massive in size with broad heads, square muzzles and ears that hang down. Their nose matches their coat colour and their eyes look sleepy underneath the wrinkles on their face. When they move, the Neapolitan Mastiff is lumbering rather than elegant.

Are Neapolitan Mastiffs easy to train?

Training a Neapolitan Mastiff can be challenging and requires a lot of patience and consistency. The breed is not a good choice for a first-time owner as they are strong-willed, large in size and will test you. It is essential to carry out socialisation training with your Neapolitan Mastiff as early as possible to ensure they become well-rounded obedient dogs when fully-grown.
