Study examines why large dogs die younger

Biologists with the Dog Aging Project analyzed DNA methylation across 864 dogs, looking at how genes are regulated rather than the genes themselves. The research offers new insight into why large dog breeds tend to have shorter lifespans than smaller ones, a long-standing puzzle in canine biology. Science and pet lovers are sharing the findings widely.

Why now: New research offers an epigenetic explanation for the well-known link between dog size and lifespan.
