Scientific Results: Protein Catabolites as Blood-Based Biomarkers of Aging Physiology: Findings From the Dog Aging Project
Published on January 27, 2026The Dog Aging Project is working to understand how and why dogs age. By studying genetics, environment, and biology, researchers hope to learn what affects healthy aging in dogs. One area of interest is the identification of aging biomarkers, which are measurements that can be made across the life of a dog that reflect their aging.
