About the Neapolitan Mastiff
The Neapolitan Mastiff is a massive guardian breed from southern Italy, with loose skin, heavy wrinkles and a large head with pendulous lips and a prominent dewlap. Its short, dense coat can be grey, black, brown or tawny. It was developed as a guard of property and family, and has a slow, rolling gait. It needs an owner who understands very large dogs.
Temperament
Calm, watchful and devoted to family, it is typically wary of strangers and can be imposing. It needs early socialisation, gentle consistent training and an experienced owner.
Exercise
Exercise needs are modest, with short walks. Avoid strenuous exercise during growth and in heat.
Grooming
The Neapolitan Mastiff has a short, coarse coat that needs little more than a weekly rub down. Its heavy wrinkles and hanging lips are the main job: wipe and dry the folds daily and clean up drool, which gathers on the chest and walls.
Care & wellbeing
Giant breed joint care, careful feeding and avoiding obesity. Heat sensitivity and skin fold care are important. Lifespan is shorter.

Think twice if
