A life table is a tabulated expression of life expectancy and mortality-related information at specified ages in a given population. This study applied the VetCompass Programme to generate life tables for the UK dog population both overall and broken down by sex, Kennel Club breed group and common breeds. Among 30,563 dogs that died between 1st January 2016 and 31st July 2020, life expectancy at age 0 was 11.23 [95% confidence interval (CI): 11.19−11.27] years. Female dogs (11.41 years; 95% CI: 11.35−11.47) had a greater life expectancy than males (11.07 years; 95% CI: 11.01−11.13) at age 0. Life tables varied widely between breeds. Jack Russell Terrier (12.72 years; 95% CI: 12.53−12.90) and French Bulldog (4.53 years; 95% CI: 4.14−5.01) had the longest and shortest life expectancy at age 0, respectively. Life tables generated by the current study promote a deeper understanding of the varied life trajectory across many types of dogs and offer novel insights and applications to improve canine health and welfare.
