More than half of Bernese Mountain Dogs die of cancer, and a published Swiss study found median survival of only around eight years, so you are taking on a short, often heartbreaking relationship with a dog the size of a small person.

Measured lifespan

10.1years, median

2.4 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 1,565 dogs of this breed. 95% confidence interval 9.8 to 10.4 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.

By the numbers

No VetCompass paper of its own yet, but the breed was one of 29 in a 2026 giant-breeds study.

In 2019, 1,513 Bernese Mountain Dogs were among 28,345 giant-breed dogs under veterinary care in the UK, 5.34% of that group. Median age at death for the breed was 7.7 years, from 63 deaths.

Across all 29 breeds pooled, 73.8% of the 4,316 dogs reviewed had at least one disorder recorded that year. The most common were Ear infection (otitis externa) 8.16%, Overweight or obese 8.02%, Aggression 5.56%. Pooled median age at death was 8.94 years (middle half 6.96 to 10.9). The paper gives no disorder figures for this breed on its own.

Health tests to ask the breeder for

Bernese Mountain Dog Club of America sets the tests a Bernese Mountain Dog 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.

Required for a CHIC number
  • Hip Dysplasia (OFA Evaluation or PennHIP Evaluation)
  • Elbow Dysplasia (OFA Evaluation)
  • Eye Examination by a boarded ACVO Ophthalmologist
  • Cardiac Evaluation
  • Degenerative Myelopathy (DM) DNA test (Bernese variant and common variant; required since 12/21/2017)

When to spay or neuter a Bernese Mountain Dog: the UC Davis study of 35 breeds has a suggested guideline for the breed. For males it is well beyond 2 years. For females, any age. The spay and neuter page has the numbers behind it and what the guidelines say for a dog this size.

Also recommended
  • von Willebrand Disease DNA test
  • Autoimmune Thyroiditis (OFA evaluation)
  • Histiocytic Sarcoma risk (HS-Pred) test

Living with a Bernese Mountain Dog

AffectionateCalmLoyalGentle

Berners are famously sweet, patient dogs that genuinely love their families and are relatively calm indoors, but the coat sheds heavily year-round and needs near-daily brushing, and the size means real costs for food, medication, and vet care. The hardest part of owning one usually is not behavioral, it is that you are quite likely to lose this dog to cancer while it is still young, often well before age 10.
