People, not millions of years of evolution, decided how big dogs would be. Breeders stretched a single species from a 2-kilogram Chihuahua to an 80-kilogram mastiff, and the big end of that range pays for it in years.
In a 2024 study of more than half a million dogs in the UK, the typical Great Dane lived to 10.6 years. The typical miniature dachshund reached 14.
A study published in Science on 8 October suggests part of that cost is written in the dogs’ DNA. A team led by Noah Snyder-Mack
