A Neapolitan Mastiff — 150–150 lb for males and 110–110 lb for females, working group, ranked No. 119 of 202 by 2025 AKC registrations — costs a typical owner in Texas about $3,397 a year, or $2,250 to $3,559 depending on food, grooming and insurance. That is 7% below the $3,671 average for giant breeds; the Great Pyrenees is the cheapest in the group and the Black Russian Terrier the dearest.
Food is the largest line at 41%. At 130 lb this dog needs about 2,085 kcal a day — roughly 38 lb of kibble a month — so brand and tier matter more than for a smaller dog: $1,233 to $1,501 a year across the standard kibbles we priced ($1,404 at the median), and several times that on fresh food. Insurance is the next line at 24%.
At No. 119 of 202 registrations it is an uncommon breed: expect a waiting list and some travel to reach a breeder, though that changes the purchase price, not the running costs modelled here. Males run about 40 lb heavier than females, which is enough to move a male into a higher parasite-prevention band — the panel's weight setting matters here. A low energy rating keeps the calorie factor at 1.4× resting energy, the lowest we use.
The smooth coat is the cheap part of owning a Neapolitan Mastiff: no clipping, an occasional bath, and a brush that lasts years. Grooming is 1% of the total at $24 a year.
First-year total: $4,420. Beyond the running costs that includes spay or neuter ($457 at Texas prices) and the puppy vaccine series with its extra visits. A giant-breed puppy outgrows everything: crate, bed, collar and harness are all bought at least twice, so treat the $230 first-month list as the first of two rounds.
The median lifespan of 9.3 years (a study of 584,734 UK dogs) is short, which keeps the lifetime total at $32,939 even though the yearly cost is above average. Only about 1 of those years are senior years, each adding $249 in extra check-ups and bloodwork.
