Large study determines the life expectancy of dogs by breed

A British study conducted by the Royal Veterinary College of 30,000 pet dogs determined the average life expectancy of 18 different breeds. Jack Russell and Yorkshire are among the longest-lived.

Are you about to buy or adopt a dog? One legitimate question to ask is how many years you will share with him. For all breeds, your vet will tell you the average number of years of life expectancy but Significant differences exist by country and genetics. Each of the 344 domestic dog breeds listed in the world by Fédération Cynologique Internationale belongs to a specific country. The “owning” country sets the standard. According to that British study conducted by the Royal College of Veterinary Medicine It cannot necessarily be extrapolated to French dogs. Furthermore, in previous studies, we can read that the Golden Retriever lives an average of 14.1 years in Japan and only 10.5 years in Denmark. This is due to different genetic types.

The peculiarity of this study published in Scientific Reports is that it concerns Over 30,000 people from 18 different genders He died between January 1, 2016 and July 30, 2020.”Provides annual life expectancy for these dog breeds as previous studies have provided information on life expectancy.Notes Benoit Heidan, a veterinarian and CNRS research engineer at the Institute of Genetics and Development in Rennes. The data comes from the database of Vetcompass, a pet health monitoring system that keeps files on 20 million dogs. Of the 97,000 dogs who died while in the study, they had Only a small third file is complete enough for scientific analysis, i.e. mention the dog’s sex, age, weight and condition. The arrangement was only able to keep 18 breeds and a group of “hybrid” dogs..

Nearly 13 years of life expectancy for a Jack Russell versus less than five years for a French Bulldog

According to this study, Jack Russell’s life expectancy at birth is 12.72 yearsThe Yorkshire Collie is 12.54 and the Border Collie is 12.10. It follows the Spaniel and the Labrador, with over 11 years of life expectancy, ahead of the Staffordshire, Cocker and Shih-Tzu.

At the bottom of the table is a short and huge dog famous for the stars: the French Bulldog. With an average lifespan of 4.53 years, it would be a treasure for its owners! It shares a low life expectancy with other flat-faced dogs including the Pug. German Shepherds are placed on average (10 years) and crossbreed dogs slightly higher (11.82 years).

About Jean-Christophe Voyerme, a veterinarian in the Lyon region, “Some species live longer than others. Smaller breeds tend to live longer. There are also selected breeds with very specific criteria, such as the bulldog’s short nose, which tend to have an increased risk of disease and reduced life expectancy.Note that, as in humans, Females live longer than males. Sterilization increases longevity by more than 10%..

Differences in longevity

However, these indicators are not the alpha and omega of a dog’s life! If certain races have genetic diseases, respiratory problems, or skeletal impairments that limit their survival, some individuals of the same sex may have longer or shorter lives. In the studied group, Bulldog is 11 years old and Jack Russell is 19 years old. In Chihuahuas we find the largest difference (between 1.5 years and 16 years of age). however, This study provides statistical data It allows people who want to buy or adopt a dog to get an idea of ​​the years of life to share. Adopting an 8-year-old dog can quickly lose him or, conversely, give him a home for many more years. “With this new dataBenoit Haydan says, “il est possible, pour le proprietaire et vétérinaire, de connaître le risque ” moyen” de survie du chien en fonction de son âge et cela peut influencer sur le choix d’adopter un chien de telle ou telle race ou de planifier ou une no”.

Choosing genetic parameters set for hundreds of years affects longevity‘, adds Dr. Voyerme, even if he is urged and involuntarily.Purebred dogs tend to age faster‘, he asserts, specifying that certain breeds live longer than others. This explains the differences in longevity from one country to another.

For a dog exchange, there is no doubt that this type of schedule can lead to disparate prices. Because mortality tables are an essential tool for human public health policy. In countries where the health and pension system is private, they are taken into account for projecting the cost of old-age insurance or disability pensions. but logically A well-groomed dog increases life expectancy. Cultural differences also extend the life of the animal, depending on whether it will be well fed or vaccinated, and it is entitled to intensive treatment or not in case of illness.
