The story where it all began

Large guardian mastiffs have lived around Naples since Roman times, working as protectors of farms and property. The breed was brought back into the spotlight after an exhibition in Naples in 1946, when painter and writer Piero Scanziani began a careful breeding programme and wrote the first standard, recognised in Italy in 1949.1 3 5

A day in the life told by a Neapolitan Mastiff

I spend my morning sprawled across the cool kitchen tiles, watching my humans shuffle in for coffee. A gentle tail wag greets each one. After breakfast patrol, I lumber into the garden for a slow sniff around the fence line, all quiet, as it should be. When the postman arrives, I give a low, rumbling woof just to remind him I'm here. My favorite part of the day is evening cuddle time on the sofa, where I rest my heavy head on a lap and let out happy sighs until bedtime.

A made-up story, just for fun. Not advice of any kind.

Treats they will love homemade and simple

Neapolitan Mastiff tip

Neapolitan Mastiffs are prone to obesity and bloat, so stick to low-calorie treats and split meals into smaller portions. Brush their teeth daily to keep those strong teeth healthy, and always ask your vet before introducing new foods.
