AAHA guidelines treat dogs as seniors in the last 25% of their expected lifespan, which for a Bullmastiff (AKC life expectancy 7–9 years) starts around age 6. Add your state in the calculator above: state prices range from about 31% below to 18% above the national average.
Why a Bullmastiff costs more to insure
Bullmastiffs are expensive to insure and short-lived: the AKC lists 7 to 9 years, and median age at death in UK records was 9.09 years. UK studies found about nine times the odds of bone cancer and ten times the odds of entropion compared with crossbred dogs. Cancer cover and the annual limit are the parts of a policy that matter most for this breed.
-
Bone cancer (osteosarcoma) Higher risk
Bullmastiffs had 9.21 times the odds of osteosarcoma compared with crossbred dogs. [source]
-
Entropion and ectropion (eyelid disorders) Higher risk
Bullmastiffs had 10.08 times the odds of entropion compared with crossbred dogs. [source]
No treatment cost shown for bone cancer (osteosarcoma), entropion and ectropion (eyelid disorders): we have not found a reliable published US cost range yet, and we do not estimate one ourselves. Ask your vet for a written estimate.
Lifetime cost: insurance vs paying the vet yourself
Insuring a Bullmastiff from puppyhood to an expected lifespan of about 8 years adds up to roughly $8,845 in typical premiums at today's prices (national average, accident and illness, no inflation).
Insurance is a hedge: most years you pay more in premiums than you claim, and a policy pays off in the years with a large bill. If you could pay the bills in this table from savings without hardship, self-insuring can make sense; see is pet insurance worth it?
Which coverage fits a Bullmastiff
- Accident and illness, not accident-only. The conditions documented for Bullmastiffs are illnesses or degenerative problems, which accident-only plans do not cover. Accident-only costs about 31% as much as accident and illness in the quote data, so it suits a tight budget but leaves out the main risks for this breed.
- Enroll early. Anything noted in your dog's records before coverage starts can be excluded as pre-existing. Premiums for a Bullmastiff are $73 a month at age 3 versus $127 at 7 in the quote data.

Is a Bullmastiff expensive to insure?
At the reference age of 6, a Bullmastiff costs 104% more than the median dog breed in our data, and ranks 150 of 154 breeds from cheapest to most expensive. The main driver in the research is bone cancer (osteosarcoma).
Does pet insurance cover bone cancer in Bullmastiffs?
Accident and illness policies generally cover it if it was not present, treated or showing signs before the policy started or during the waiting period; that is the NAIC Model Act definition of a pre-existing condition. Policies that exclude hereditary or congenital conditions must say so in their disclosures.
At what age is a Bullmastiff a senior, and what happens to the price?
AAHA guidelines define a senior dog as one in the last 25% of its expected lifespan. With an AKC life expectancy of 7–9 years, that is about age 6 for a Bullmastiff. In the quote data its premium at 7 is 1.8 times the price at age 3.
How much does it cost to insure a Bullmastiff for life?
If you insure from puppyhood to an expected lifespan of about 8 years, typical premiums add up to roughly $8,845 at today's prices (no inflation, no state adjustment). Premiums usually rise over time, so the real figure is likely higher.
