Revealed: The Dog Breeds with the Longest (and Shortest!) Lives
A comprehensive study, recently published in Scientific Reports, has unveiled fascinating insights into the life expectancies of different dog breeds in the UK. This extensive research, which delved into the lives of over half a million dogs, could be a game-changer in understanding breed-specific health risks and longevity.
The study, led by Kirsten McMillan and her team, analyzed a massive database of 584,734 dogs sourced from various UK entities including breed registries, veterinary practices, pet insurance companies, animal welfare charities, and academic institutions. The database included a wide array of dogs, spanning 155 pure breeds and numerous crossbreeds. Interestingly, the data also documented the lifespan of 284,734 dogs that had passed away, providing a rich source of information on canine longevity.
One of the study’s most striking findings is the correlation between a dog’s breed, size, and head shape, and its life expectancy. Small long-nosed breeds, known as dolichocephalic breeds, like Whippets, Miniature Dachshunds, and Shetland Sheepdogs, emerged as the ones with the highest median life expectancy of 13.3 years. On the other end of the spectrum, medium-sized flat-faced breeds, or brachycephalic breeds, such as English Bulldogs, showed the lowest life expectancies, with males averaging just 9.1 years.
The research didn't stop there. It also shed light on the life expectancy of some of the UK’s most popular breeds. Labradors, for instance, have a median life expectancy of 13.1 years, while Jack Russell Terriers and Cavalier King Charles Spaniels boast life expectancies of 13.3 and 11.8 years, respectively. Interestingly, purebred dogs tend to live longer than crossbreeds, with a median life expectancy of 12.7 years compared to 12.0 years for crossbreeds. The study also noted a slight edge in longevity for female dogs over males.
It's important to note, however, that these findings are specific to the UK dog population and may not necessarily apply globally. Additionally, the definition of crossbreeds in this study was confined to dogs not recognized as kennel club purebreds.
This groundbreaking research not only offers valuable insights for dog owners and breeders but also has significant implications for veterinary medicine and canine welfare. By highlighting the breeds most at risk of an early death, this study paves the way for more focused healthcare strategies and improved quality of life for our beloved canine companions.
