Study of 864 dogs examines why large dogs die younger

Original: 🐕 NEW: Biologists analyzed # DNA methylation across 864 # dogs in the Dog Aging Project, comparing how genes are regulat

Biologists analyzed DNA methylation across 864 dogs enrolled in the Dog Aging Project, looking at how genes are regulated rather than the genes themselves. The work, covered by Popular Science, aims to explain why large dog breeds tend to have shorter lifespans than smaller ones, a long-standing puzzle in canine biology.

Why now: The finding speaks to a common pet-owner question about why bigger dogs live shorter lives, and ties into wider interest in aging and longevity research.
