A front page article titled “New research links long kisses to longevity” by Emily Anthes in the New York Times reported on a study conducted in the UK by the welfare charity Dog Trust Foundation, written by its author and data manager Kirsten McMillan. There are 584,734 dogs in the database, and the content is compiled with the help of breed registry, insurance companies, veterinary companies, etc.
Most dogs are purebred dogs, but at the same time, the numerical records of these different breeds may be prone to some deviations and do not completely represent the general canine population in the UK. In addition to variety, factors such as genetics, environment and diet must also be considered. They reported that the flat-faced (short-headed) varieties had a lifespan of 11.2 years, while the long-faced varieties had a lifespan of 12.1 to 12.8 years. The study also found that the average lifespan of purebred dogs is 12.7 years, while the average lifespan of hybrid dogs is 12 years.
This certainly goes against the general idea that hybrid dogs are healthier than purebred dogs. "I think this is a more complex issue than that. Some purebred dogs are usually very healthy," said Audrey Ruppel, a veterinarian at Virginia Tech who was not involved in the study. "
