For dog owners, having an idea of their companion’s life expectancy can allow him to take various measures at different key stages of his life (a different diet, less sustained physical activity …) in good health. . Members of the Royal Veterinary College are applied to define the life expectancy of dogs in the UK and are based on a sample of over 30,000 canids by breed, sex and spay. The goal of such a study is to allow homeowners to “develop realistic expectations for the remaining life typical of their dogs thanks to the knowledge of the hope of life„. Then guide them, in the company of veterinarians, on the most appropriate medical decisions to make.
18 races and 30,563 dogs studied
For this study, the researchers decided to approach the issue of life expectancy differently from other studies of the same kind, in the form of a mortality table. “Instead of offering a unique value for the average age at death, a mortality table is a tabulated expression of life expectancy and the probability of death in different age groups of a given population.According to the authors of this study, this format is used, for example, by the National Institute of Statistics and Economic Studies (INSEE). It is then possible to follow, for each age, the probability of death in the “year and deduce the overall health of the group. This study provides the first table of its kind for British dogs. It uses the anonymized VetCompass database and translates the life expectancy of 18 crossbred dogs and dogs after 30,563 canids of which 47.7% were females and 57.4% were spayed.

According to the results, life expectancy at birth for British companion dogs was 11.23 years, and this figure decreased with age. Indeed, the probability of death at each interval of the year increased almost systematically (except at the very beginning of life). Females have a longer life expectancy than males for up to 12 years. Then it became the same for both sexes. The study found that neutered dogs had a better overall life expectancy.
