Do Bullmastiffs have health problems?
Bullmastiffs have a higher-than-average health burden. Their large size and breed characteristics mean owners should go in with eyes open — and with solid pet insurance.
A powerful guard breed with a gentle family side. The Bullmastiff is fearless with strangers but deeply affectionate with those it loves.
Known health concerns in Bullmastiffs
These are the conditions most commonly seen in the breed — not guarantees, but things to be aware of:
- Brachycephalic Obstructive Airway Syndrome (BOAS): The flat-faced structure of the Bullmastiff causes narrowed nostrils, an elongated soft palate, and a narrowed trachea — which together restrict airflow. Symptoms include snoring, rapid breathing, exercise intolerance, and overheating. Mild cases are managed with weight control and limiting exercise in heat; severe cases require surgical correction. This is not a minor cosmetic issue — it affects quality of life.
- Hip and Elbow Dysplasia: Abnormal development of the hip or elbow joint causes pain and progressive arthritis. It's partly hereditary — which is why BVA screening of breeding dogs matters. Keeping puppies slim during growth and avoiding high-impact exercise before 12–18 months reduces severity.
How to reduce health risks in Bullmastiffs
Most health problems are either hereditary (managed by choosing a responsible breeder) or lifestyle-related (managed by the owner). Here's what actually moves the needle:
- Choose health-tested parents: Ask breeders for relevant health test results — BVA hip and elbow scores, BOAS assessments, eye tests where relevant. A responsible breeder won't be offended.
- Maintain a healthy weight: Obesity is the most preventable health issue in dogs and it compounds everything — joints, heart, and lifespan. Weigh your Bullmastiff monthly and adjust food accordingly.
- Annual vet check-ups: Not just for vaccines. A thorough annual exam checks heart, weight, teeth, eyes, and joints. Most problems caught early are far cheaper and more treatable.
- Appropriate exercise: Don't over-exercise puppies before 12–18 months — developing joints are vulnerable. Consistent exercise throughout life maintains condition better than irregular bursts.
- Pet insurance from puppyhood: Even a generally healthy Bullmastiff can develop a condition requiring expensive treatment. Insuring before any issues arise avoids pre-existing condition exclusions. Lifetime cover is worth the premium over accident-only policies.
The lifetime vet cost of a dog depends far more on diet, weight management, and preventative care than on the breed. A well-kept Bullmastiff will nearly always outlive and outperform a neglected one from the same litter.
Pet insurance for Bullmastiffs
UK insurance for a Bullmastiff typically costs £55–£110 per month. Given their health profile, lifetime comprehensive cover is worth the premium. A single BOAS surgery or orthopaedic procedure can cost £3,000–£8,000 — significantly more than years of insurance premiums.
Premiums increase with age. Insuring at puppyhood locks in lower rates and prevents exclusions for conditions that develop later.
