Exploring the Science of
Canine Healthy Aging
Evidence-based perspectives on aging biology, nutrition, biomarkers, and the emerging science of canine geronutrition.
Biomarkers in Canine Aging Research
Interpretation, Variability, and Limits
Biomarkers can provide valuable windows into biological aging, but no single measurement tells the whole story. Explore how biomarkers should be interpreted within the broader context of physiology, study design, individual variability, and time.
Explore the Science
Perspectives on the biology of aging and the role nutrition may play in supporting healthy function across the canine lifespan.
What Is Canine Geronutrition?
An introduction to the emerging intersection of nutrition, aging biology, and long-term functional health in dogs.
Cellular Turnover and Nutrient Demand in Aging Dogs
How tissue renewal, cellular maintenance, and changing physiological demands may influence nutritional requirements across the aging process.
Telomere Dynamics in Companion Animals
Telomeres are frequently associated with biological aging, but their interpretation is more nuanced than a simple “longer is better” narrative.
Understanding Evidence in Canine Aging Research
From mechanistic observations to controlled interventions: understanding what different types of scientific evidence can—and cannot—tell us.
Science advances through evidence— and careful interpretation.
Throughout CGI Insights, we distinguish established evidence from study observations, mechanistic hypotheses, exploratory findings, and areas where scientific uncertainty remains.
