An extensive study established the life span of dogs according to their breed

A British study conducted by the Royal Veterinary College of 30,000 pet dogs established life expectancy for 18 different breeds. Jack Russell and Yorkshire have one of the longest living.

Will you buy or adopt a dog? One of the legitimate questions to ask is how many years will you share with him. For all breeds, the veterinarian will inform you of an average number of years of life expectancy but There are many differences depending on the country and genetics. Each of the 344 breeds of pet dogs listed in the world by the Fédération Cynologique Internationale belongs to a particular country. The “owned” country sets the standard. As such the British study conducted by the Royal Veterinary College need not be extrapolated to French dogs. In addition, in previous studies, we read that the Golden Retriever lived an average of 14.1 years in Japan and only 10.5 years in Denmark.

The specificity of this study published in Scientific Reports is that it is relevant to more than 30,000 individuals of 18 different races died between January 1, 2016 and July 30, 2020. Data from the Vetcompass database, an animal health monitoring system, with records of 20 million dogs. Of the 97,000 dogs that died during the study period, only a small third had a sufficiently complete file for scientific analysis, i.e. mentioning the dog’s sex, age, weight, sterilization status. Since they need a minimum number of individuals per race for statistical stability, the ranking was only able to keep 18 breeds and a group of “crossbred” dogs.

Nearly 13 years of life expectancy for Jack Russell versus no five for the French Bulldog

According to this study, Jack Russell has an average life expectancy at birth of 12.72 years, the 12.54-year-old Yorkshire and the 12.10-year-old Border Collie. The Spaniel and the Labrador follow, with more than 11 years of life expectancy, ahead of Staffordshire, the Cocker and the Shih-Tzu.

Below the table, a short and large dog popular with the stars: the French Bulldog. With an average life expectancy of 4.53 years, it can be a treasure for its owners! It shares the low life expectancy of other flat-faced dogs including the Pug. The German Shepherd is laid on average (10 years) and the crossbred dogs above are small (11.82 years).

To Jean-Christophe Vuillerme, veterinarian of the Lyon region, “there are varieties that live longer than others. Smaller varieties are more likely to live longer. There are also varieties that are selected with specific behaviors, such as the Bulldog’s short noses, which are likely to increase the risk of disease and reduce life expectancy.Note that, like humans, women live longer than menexcept in the case of sterilization.

Differences in longevity

However, these signs are not the alpha and omega of a dog’s life! If other races suffer from genetic diseases, respiratory problems or skeletal weakness that limits their survival, some individuals of the same race may have a longer or shorter lifespan. In the cohort studied, one Bulldog reached 11 years of age and one Jack Russel 19 years of age. In Chihuahua, we see the largest difference (between 1.5 years and 16 years of life). However, this study provides statistical data and allowed people who wanted to buy or adopt a dog with an idea of ​​life years to share. Adopting an 8-year-old dog can lead to losing him quickly or, conversely, to offering him a home for many years.

Choosing specific genetic criteria over hundreds of years can affect longevity“, added Dr. Vuillerme, even if it is prompted and not voluntary.”Purebred dogs tend to age faster“, he lines up, specifying that some strains live longer than others. This explains the differences in longevity from one country to another.

For dog mutuals, there is no doubt that this type of table can lead to different prices. Because mortality tables are an essential tool for people’s public health policies. In countries where the health and retirement system is private, they are considered to anticipate the cost of old age insurance or disability pensions. But logically, a dog with good health care increases his life expectancy.
