What was done
Mortality and longevity data on 5,663 deceased dogs registered with the UK Kennel Club were collected through an owner-based questionnaire to evaluate breed-specific lifespans and causes of death.
What was found
The overall median age at death was 10.33 years (interquartile range: 7.17-12.83 years). The most frequently reported causes of death were old age (13.8%), unspecified cancer (8.7%), heart failure (4.9%), and unknown causes (5.1%). Median longevity varied widely across breeds, ranging from 7.67 years in Dobermann Pinschers to 12.71 years in West Highland Terriers, with substantial variation in cause of death distribution across breeds.
Why it matters
These breed-level survival estimates identify specific breeds with foreshortened lifespans or high cause-specific mortality, providing evidence to guide targeted breeding reforms and canine welfare improvements.
Limits
The study relies entirely on owner self-reporting rather than verified veterinary records or necropsies, introducing misclassification and recall bias. Findings are restricted to UK Kennel Club registered purebred dogs and cannot be generalized to mixed-breed dogs or other geographic populations.
