“Why large dogs age faster than small ones, and other October research highlights”
Large dogs age faster than small dogs due to epigenetic changes.
Key points
- ASU researchers link dog aging differences to DNA methylation and jumping genes.
- Study uses 864 dogs from the Dog Aging Project to map epigenetic patterns.
- LINE1 transposable elements show greater methylation loss in giant breeds.
- Aging in dogs tied to reduced regulation of jumping genes, accelerating aging.
- Findings published in Science, DOI 10.1126/science.aeb2986 in 2026.
