Animal health: New life expectancy estimates for UK dogs suggest Jack Russell Terriers live longest

A paper by Jack Russell Terrier and Yorkshire Terrier reports that the latest study reveals the longest lifespan of any breed in the UK is published in Scientific Reports.On the other hand, it was also found that among the flat-faced dog breeds (short-headed breeds) such as the French Bulldog and the pug, the dog breed with the shortest life expectancy is included.

Now, Kendy Tzu-yun Teng, Dan O'Neill and colleagues use the VetCompass database to analyze 2016 dog death records from 2020 to 3 registered by animal hospitals across the UK, and the Kennel Club in the UK. Classified into 563 dog breeds and hybrid groups certified by.The authors then created a life table that calculated life expectancy in 18-year increments from birth (0 years) throughout the life of the dog.

Jack Russell Terrier (12.72) had the longest life expectancy at birth, followed by Yorkshire Terrier (12.54), Border Collie (12.10) and Springer Spaniel (11.92).On the other hand, the French Bulldog (4.53 years old) had the shortest life expectancy at birth, about 7.39 years older than other brachycephalic species with a short life expectancy, such as the English Bulldog (7.65 years old) and Pug (3 years old). It was short.The authors suggest that the cause of such short life expectancy may be the high health risks known to occur in these brachycephalic species.

Life expectancy at birth for all breeds was estimated to be 11.1 years for male dogs, four months shorter than for female dogs.Life expectancy of castrated dogs (female 4 years, male 11.98 years) was longer than that of non-castrated dogs (female 11.49 years, male 10.50 years).The authors consider the potential benefits of castration and the consequent prolongation of life expectancy, and discuss whether castration reflects the strength of the owner's sense of responsibility and the care given to dogs.

The authors conclude that the study will allow us to understand the life expectancy of dogs of different ages, as in humans, and may improve life expectancy estimates for different breeds in the United Kingdom. ing.Other benefits may include the ability to accurately estimate the life expectancy of a dog when caring for a new owner at a dog shelter.
