Mastiff: Health & Insurance

Last update: July 11, 2025

The Mastiff is a gentle giant known for its loyal temperament, but its massive size contributes to a significant medical fragility.
This giant breed is particularly susceptible to severe and costly health problems, including hip and elbow dysplasia, cruciate ligament injuries, bloat (Gastric Dilatation-Volvulus), and heart conditions like dilated cardiomyopathy (DCM).
Due to the high likelihood of developing these serious hereditary and size-related conditions, the Mastiff has a breed vulnerability score of 9 out of 10.
While routine annual vet care can average $800 to $1,500, treating a common ailment is far more expensive: emergency surgery for bloat can cost up to $8,000, hip dysplasia treatment often exceeds $7,000 per hip, and cancer therapies can surpass $10,000.
Many standard insurance policies are unsuitable for Mastiffs, as they often have low payout caps that are insufficient for giant breed surgery costs, exclusions for hereditary conditions, or lengthy waiting periods for orthopedic issues.
To ensure adequate protection, owners should consider insurers with robust coverage for breed-specific risks.
➡️ Spot is a top choice due to its standard 14-day waiting period for orthopedic issues and its unlimited payout option.
➡️ Trupanion is well-suited for managing chronic conditions like arthritis or DCM with its per-condition deductible and no payout limits.
➡️ Embrace offers a strong, comprehensive plan where the orthopedic waiting period can be reduced to 14 days with a vet exam.
Below, you will find a complete health sheet, a detailed comparison table of the best plans, and essential cost-saving tips for your Mastiff.

Is Pet Insurance Relevant for a Mastiff?

Breed Risk Index for Mastiff: 8/10

Mastiffs have a high veterinary risk index due to the breed’s predisposition to severe, costly, and often acute health problems. Major contributing factors include a high incidence of orthopedic diseases (hip and elbow dysplasia, cruciate ligament injuries) requiring major surgeries—with per-case costs reported by the American College of Veterinary Surgeons often exceeding $3,500–$7,000. Large-breed cardiac disorders such as dilated cardiomyopathy and life-threatening emergencies like Gastric Dilatation-Volvulus (bloat) are prevalent and frequently fatal without immediate intervention; bloat surgery alone often costs $2,500–$6,000. Cancer rates in giant breeds are also elevated relative to the general canine population, necessitating insurance with robust cancer and chronic care coverage. Furthermore, due to their size, almost all medical and surgical interventions, hospitalizations, and drug regimens are disproportionately expensive, as documented in claims analytics from Trupanion and Healthy Paws. Good plans must offer high or unlimited annual caps, short waiting periods for orthopedic and hereditary conditions, and broad emergency coverage. The collision of severe, expensive, and recurring risks leads to a high risk score, verified by veterinary orthopedic and cardiology literature and the HelloSafe pet insurance database.

How to Choose the Best Insurance for Your Mastiff

When choosing insurance for your Mastiff, select a policy with a high annual limit—ideally at least $2,000 or, even better, unlimited.

Mastiffs face expensive orthopedic surgeries for hip and elbow dysplasia, as well as emergency procedures for bloat; less comprehensive plans may leave you underinsured.

Seek out a high reimbursement rate, preferably 80–100%, to cover the steep costs of chronic arthritis, heart disease (like DCM), and cancer treatment often seen in this giant breed.

A low annual deductible, under $100, further minimizes your out-of-pocket burden and can make a substantial difference over time.

Be vigilant about exclusions: ensure the policy does not exclude breed-specific or hereditary issues such as cruciate ligament tears, which are common in Mastiffs.

Finally, insure your Mastiff as early as possible—before any symptoms arise—to maximize coverage for future claims, since pre-existing conditions are universally excluded by insurers.

These precautions will help ensure financial protection for your dog's lifelong care.

FAQ

What key health risks should Mastiff insurance always cover?

Mastiffs are highly susceptible to orthopedic issues like hip and elbow dysplasia, cruciate ligament injuries, and heart disease such as dilated cardiomyopathy. Their large size also puts them at significant risk for bloat (Gastric Dilatation-Volvulus), a sudden emergency requiring costly surgery. Ensure your policy covers these conditions and includes provisions for both hereditary and chronic illnesses.

Why is a high or unlimited annual payout especially important for a Mastiff?

Because Mastiffs are a giant breed, even routine treatments and medications can be much more expensive than for smaller dogs. Emergency bloat surgery or joint replacements can cost several thousand dollars each. Choosing a policy with a high or unlimited annual cap ensures you’re financially protected if your Mastiff ever faces major surgeries or extended hospitalizations.

Do pet insurance policies for Mastiffs cover pre-existing conditions?

No, pre-existing conditions are generally excluded from all US pet insurance. This means any illness, injury, or symptom that appears before the policy starts (or during the waiting period) won’t be reimbursed. That’s why it’s crucial to insure your Mastiff as a puppy or before any health problems are detected to maximize future coverage.

Are waiting periods different for orthopedic risks like hip dysplasia in Mastiffs?

Yes, most plans include a waiting period for orthopedic conditions—ranging from 14 days to 12 months. Some providers let you waive or shorten this waiting time with a recent orthopedic exam. Paying attention to the waiting period makes a big difference, as Mastiffs are at high risk for early joint problems.

Should I consider coverage for cancer and prescription diets in a Mastiff policy?

Absolutely. Mastiffs can be prone to certain cancers and may require specialized treatments that are very costly. Including cancer coverage and reimbursement for prescription diets ensures you have financial support for advanced therapies, diagnostics, and long-term condition management that may arise during your dog’s life.

How can I avoid coverage gaps in a Mastiff’s insurance plan?

Look for policies with no per-condition limits, short waiting periods, and no hidden exclusions for hereditary or breed-specific conditions. Read the fine print on sub-limits for dental, rehab, or alternative care, and ask the insurer directly about any possible breed-specific policy loopholes before enrolling.
