A life table is a tabulated expression of life expectancy and mortality-related information at specified ages in a given population. This study utilised VetCompass data to develop life tables for the UK companion dog population 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 allow 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. The current study helps promote further understanding of life expectancy, which will benefit pet owners and the veterinary profession, along with many other sectors.
生命表是以表格形式呈现的特定人群在特定年龄的预期寿命和死亡率相关信息。本研究利用 VetCompass 数据为英国伴侣犬群体制定了生命表，并按性别、英国养犬俱乐部品种组和常见品种进行了细分。在 2016 年 1 月 1 日至 2020 年 7 月 31 日期间死亡的 30563 只狗中，0 岁时的预期寿命为 11.23 年（95%置信区间：11.19-11.27）。母犬（11.41 年；95%置信区间：11.35-11.47）的预期寿命大于公犬（11.07 年；95%置信区间：11.01-11.13）。生命表在不同品种之间差异很大。杰克罗素梗（12.72 年；95%置信区间：12.53-12.90）和法国斗牛犬（4.53 年；95%置信区间：4.14-5.01）的 0 岁时的预期寿命最长和最短。本研究生成的生命表可以更深入地了解许多类型犬的不同生命轨迹，并为改善犬只健康和福利提供新的见解和应用。本研究有助于进一步了解预期寿命，这将使宠物主人和兽医行业以及许多其他领域受益。
