According to the study, the average life expectancy of all dogs is around 12.5 years – but when it comes to longevity, which breed is the top dog? Take our quiz to find out more, then scroll to the bottom to see a list of the dog breeds they’ve researched.

The study comes with some caveats – the data on the 584,734 dogs was collected from a range of sources, and may be affected by representational bias.

But McMillan, who says it is the biggest study of its kind to date in Britain, hopes the findings will trigger further research. “We provide clear evidence that some breeds or groups do not do very well, and are at greater risk of having a shorter lifespan.”

She emphasizes that pet owners should remember that an individual dog’s life varies greatly based on human-directed environments, including diet, exercise , lifestyle and what owners invest in them.

Ultimately, she hopes the study will empower pet owners to make more informed decisions about the commitments of looking after a dog, and that she will “be an inspiration to others,” a ‘ including researchers, veterinarians, breeders and policy makers, to “move towards the development of the dog. the lives of our canine companions.”
