Big dogs age faster, and their epigenomes show it
Original: Big dogs really do age faster, and their epigenomes show it
New research indicates that larger dog breeds age faster than smaller ones, with differences visible in their epigenomes, the chemical marks on DNA that track biological aging. The findings help explain why big dogs live shorter lives and add to scientific understanding of how aging rates can vary within a single species.
Why now: The link between body size and biological aging in dogs is a striking scientific finding that interests pet owners and aging researchers alike.
