A Mastiff — 160–230 lb for males and 120–170 lb for females, working group, ranked No. 40 of 202 by 2025 AKC registrations — costs a typical owner in Texas about $3,475 a year, or $2,261 to $3,676 depending on food, grooming and insurance. That is 5% 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 56%. At 170 lb this dog needs about 2,914 kcal a day — roughly 54 lb of kibble a month — so brand and tier matter more than for a smaller dog: $1,724 to $2,098 a year across the standard kibbles we priced ($1,962 at the median), and several times that on fresh food. Insurance is the next line at 23%.
Ranked No. 40 of 202, it is common enough that most vets and groomers see the breed regularly. Males run about 50 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 short double coat sheds hard twice a year but needs no clipping; most owners manage with a de-shedding brush and a few baths. Salon visits are optional — the $24 shown assumes home grooming only.
First-year total: $4,498. 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 years (a study of 584,734 UK dogs) is short, which keeps the lifetime total at $32,302 even though the yearly cost is above average. Only about 1 of those years are senior years, each adding $4 in extra check-ups and bloodwork.
