The life expectancy of dogs according to their breed

For dog owners, having an idea of ​​the life expectancy of their companion can allow them to take different measures at different important stages of its life (a different diet, less sustained physical activity, etc.) to maintain it. good health. Members of the Royal Veterinary College have therefore used it to define the life expectancy of dogs in the United Kingdom based on a sample of more than 30,000 dogs by breed, sex and sterilization. The purpose of such a study is to provide the owners of “develop realistic expectations for the typical remaining life expectancy of their dogs through knowledge of life expectancy“. Which then guides them, in the company of veterinarians, on the most appropriate medical decisions to be made.

18 breeds and 30,563 dogs examined

For this study, the researchers decided to approach the problem of life expectancy differently than other studies of the same kind, in the form of a mortality table. “Instead of offering a single value for the Middle Ages at death, a life table is a tabulated expression of life expectancy and probability of death in different age groups in a given population.“, in the words of 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 to derive the This study provides the first table of its kind for British dogs, using the anonymised VetCompass database and translating the life expectancy of 18 breeds and crosses from after 30,563 dogs, of which 47.7% were females and 57.4% were sterilized.

According to the results obtained, the life expectancy at birth of British pet dogs was 11.23 years, and this figure decreased with age. In fact, the probability of death at each year interval increased almost systematically (except at the beginning of life). The females hold up to 12 years an expected lifespan higher than the males. Then it became identical for both sexes. The study reveals that neutered dogs generally had a better life expectancy.
