The life span of dogs according to their breed

For dog owners, having an idea of ​​their companion’s life span will enable them to take different steps at different key stages of his or her life (another diet, less sustained physical activity, etc.) to sustain it. good health. Members of the Royal Veterinary College therefore applied themselves to determine the life expectancy of dogs in the United Kingdom based on a sample of more than 30,000 canids according to breed, sex and sterilization. The aim of the study was to allow the owners of “developing realistic expectations for the typical residual length of their dogs through knowledge of life expectancy“. Guiding them, along with veterinarians, in the most appropriate medical decisions to make.

18 breeds and 30,563 dogs were studied

For this study, the researchers decided to approach the problem of life expectancy differently from other studies of the same class, in the form of a mortality table. “Instead of offering a value for the average age of death, the life record is a tabulated expression of life expectancy and mortality rates in different age groups in a population.“, In the words of the authors of this study. This format is for example used by the National Institute of Statistics and Economic Studies (Insee). Then it is possible to follow, for each age, the probability of death in the year and to determine the overall health of the group.This study provides the first table of its variety for British dogs.It used the anonymous VetCompass database and interpreted the life expectancy of 18 breeds and crosses from after 30,563 dogs of which 47.7 % were females and 57.4 % were sterilized.

Jack Russell took the lead

According to the results obtained, the birth life for British domesticated dogs is 11.23 years, and this number decreases with age. In fact, the probability of death at each interval of the year increased almost systematically (except at the beginning of life). Females maintain up to 12 years of life expectancy longer than males. Then, it became the same for both sexes. The study revealed that sterilized dogs had an overall better life expectancy.
