Scientists say they may know why big dogs die younger
Original: Large dog breeds die younger. Biologists think they finally know why.
Large dog breeds live significantly shorter lives than small ones, and biologists believe they have found a possible explanation for the pattern. The finding sheds light on how body size, growth rates and ageing may be connected in dogs, a species with an unusually wide range of sizes. The research is drawing attention from pet owners and scientists interested in the biology of ageing.
Why now: New biological research offers a potential explanation for a well-known but long-unexplained pattern in dogs.
