Can Old Dogs Teach Humans to Live Longer?

A major new research project is investigating whether dogs can provide the secret to a longer, healthier human life. The study will collect data from thousands of pet dogs across the United States. Scientists aim to understand the factors that drive canine aging and longevity. Because dogs share our environment and get many of the same age-related diseases, they are a powerful model for human health. Their shorter lifespans allow researchers to see results more quickly. The project will analyze genetics, lifestyle, and diet. The goal is to find patterns that could lead to interventions for both species. "If we can learn how to slow aging in dogs," one researcher noted, "the applications for human medicine could be transformative."
