Summary

Story summary

A study of nearly 800 dogs identifies post-translationally modified amino acids (ptmAAs) in canine blood that correlate with aging.
Researchers from Tufts University and the University of Washington conducted the study.
The findings show about 40% of small molecules in dog blood change with age, linking gut health and kidney function.
Future work will track these metabolites over time to assess their impact on aging in dogs and humans.
