Canine Aging Research Evidence at a Glance
Explore research relevant to canine healthy aging through concise, structured evidence summaries that separate study observations from scientific interpretation.
Each summary identifies what was studied, what researchers observed, what the findings may mean, and where important uncertainties remain.
Research is easier to evaluate when its context is visible.
Scientific studies differ in population, design, duration, endpoints, analytical methods, and strength of inference. Those differences matter when deciding what a finding can reasonably tell us.
CGI Evidence Summaries are designed to make that context easier to see. Rather than reducing a study to a headline, each summary presents the research question, design, observations, limitations, and publication status together.
Browse by Scientific Area
Healthy aging involves multiple interacting biological systems. Evidence is therefore organized by scientific question rather than by commercial product or brand.
Aging Biology
Research examining cellular maintenance, metabolic adaptation, tissue renewal, physiological resilience, and biological change across the canine lifespan.
Explore Evidence →Geronutrition
Studies examining how nutritional inputs and changing physiological needs may relate to maintenance, resilience, and healthy function in older dogs.
Explore Evidence →Biomarker Science
Research using clinical, inflammatory, oxidative, metabolic, molecular, or multi-omic measurements to characterize biological change.
Explore Evidence →Gut & Metabolic Health
Evidence examining intestinal physiology, microbial ecology, nutrient utilization, metabolic signaling, and age-related change.
Explore Evidence →Functional Resilience
Research focused on mobility, activity, cognition, recovery, vitality, and other outcomes relevant to everyday healthspan.
Explore Evidence →Intervention Research
Controlled and longitudinal studies evaluating nutritional approaches through predefined biological or functional outcomes.

Every study is presented in a way that allows the research itself to remain the focus.
Why the Study Matters
A short explanation of the scientific question and why it is relevant to canine healthy aging.
Study at a Glance
Population, sample size, design, duration, intervention or exposure, comparator, and major endpoints.
What Researchers Observed
The principal study findings are described separately from broader interpretation.
What It May Mean
Biological relevance is discussed in relation to study design and the broader scientific context.
What It Does Not Prove
Important boundaries are made explicit so findings are not extended beyond what was actually measured.
Limitations & Status
Sample size, population, duration, publication status, uncertainty, and other relevant limitations are shown.
Study Evidence Summaries
CGI is building a curated collection of studies relevant to canine aging, healthspan, nutrition, and biological function.
Evidence summaries are being added as scientific reviews are completed.
CGI prioritizes complete, source-linked summaries over placeholder entries. New records will be added as individual studies have been reviewed and their design, findings, limitations, and publication status can be presented accurately.
Similar words can describe very different conclusions.
CGI uses several simple distinctions to help keep scientific interpretation proportional to the evidence available.
Two factors changing together does not automatically establish that one caused the other.
A biological marker may change without proving that biological aging itself has been reversed.
A statistically detectable difference may or may not represent a meaningful biological effect.
Replication, consistency, methodology, and the broader evidence base all matter.
Findings should not automatically be generalized beyond the animals, conditions, and timeframe actually studied.
Different study designs answer different questions.
Evidence strength cannot be reduced to a single label. Study design, publication status, replication, population relevance, and methodological quality all contribute to interpretation.
Controlled Intervention
Defined interventions are compared under structured study conditions to assess differences in prespecified outcomes.
Longitudinal Research
Individuals are followed over time to characterize trajectories, change, and temporal relationships.
Observational Research
Naturally occurring relationships are examined without assigning a controlled intervention.
Real-World Evidence
Outcomes are examined in broader, less-controlled populations and real-life settings.
Mechanistic Research
Biological pathways and processes are studied to investigate how observed effects may occur.
Evidence Synthesis
Multiple studies are evaluated together to examine consistency, uncertainty, and the overall direction of the evidence.
The evidence comes first. The framework stays in the background.
CGI uses a consistent structure when reviewing scientific studies so readers can distinguish experimental observations from interpretation, uncertainty, and publication status.
The purpose of that structure is not to create a proprietary rating system. It is to make the underlying evidence easier to inspect.
