New research from the Dog Aging Project shows biological signals that help predict lifespan in people also appear in dogs. The study appears in The Journals of Gerontology and the work is supported by the WoodNext Foundation.
Researchers analyzed blood samples and owner surveys from a long-term community science study. They measured thousands of metabolites, which are small chemicals from normal body processes, and looked for groups of molecules that form a pattern or "fingerprint." These measurable patterns are called biomarkers. To check if the same signals appear in people, the team compared dog results with five large published human studies and found similar links to earlier or later death.
