A dog this size shouldn't be dying at 8 to 10 years old, but that's the typical lifespan for a Saint Bernard — add in constant drooling, real bloat risk, and a genuine chance of four-figure vet bills for hip dysplasia or bone cancer, and the 'gentle giant' image sold at pickup rarely matches the true lifetime cost.
9.3years, median
3.2 years below the all-dog median of 12.5.
Measured, not estimated: the middle age at death across 584,734 UK dogs, 284,734 of them deceased. Based on 1,638 dogs of this breed (listed in the study as "St Bernard"). 95% confidence interval 9 to 9.8 years. Half lived longer than this, half did not. UK dogs, so treat it as the best available figure rather than a promise about yours.
In the same study, large breeds as a group had a median of 11.9 years and medium-muzzled breeds 12.8. This breed is large and medium-muzzled.

Saint Bernard Club of America sets the tests a Saint Bernard needs for a CHIC number in the OFA's open database. A CHIC number means the tests were done and the results are public. It does not mean the dog passed them: ask for the results for both parents, or look them up yourself on ofa.org.
- Hip Dysplasia (OFA Evaluation or PennHIP Evaluation, minimum 24 months)
- Elbow Dysplasia (OFA Evaluation, minimum 24 months)
- Eye Examination by a boarded ACVO Ophthalmologist (minimum 22 months)
- Cardiac Evaluation (Congenital Cardiac Exam by a boarded cardiologist, Advanced Cardiac Exam, or Basic Cardiac Exam by a boarded cardiologist; minimum 24 months)
- Degenerative Myelopathy (DM) DNA test
When to spay or neuter a Saint Bernard: the UC Davis study of 35 breeds has a suggested guideline for the breed. For males it is any age. For females, 6 months or later; the authors suggest well beyond a year. The spay and neuter page has the numbers behind it and what the guidelines say for a dog this size.
- Autoimmune Thyroiditis (OFA evaluation)

Living with a Saint Bernard
Saint Bernards are genuinely calm and patient, not high-energy dogs, but living with one means near-daily drool cleanup, heavy shedding, and frequent ear cleaning because of the floppy ears. The bigger issue is logistics and grief on a short timeline: this is a dog that eats, costs, and needs handling like a small horse, for a life that ends early even measured against other large breeds.
Health you should know about
- Gastric dilatation-volvulus (bloat) — a sudden, life-threatening stomach twist that deep-chested giant breeds like the Saint Bernard are at significantly elevated risk for compared with the average dog.
- Hip dysplasia — malformed hip joints, extremely common in giant breeds carrying this much body weight.
- Osteosarcoma — an aggressive bone cancer disproportionately seen in giant breeds, often requiring amputation and chemotherapy.
- Cervical vertebral instability ('wobbler syndrome') — spinal cord compression in the neck that causes an unsteady gait and can progress to weakness.
