CGI HEALTHSPAN FRAMEWORK

Six Biological Domains of Canine Healthy Aging

CGI examines canine healthspan as a multi-system biological process. These six domains provide a structured framework for organizing aging biology, biomarkers, nutritional research, and functional outcomes.

Functional Vitality

Body condition, muscle maintenance, mobility, physical activity, and the capacity to maintain everyday function during aging.

Gut–Metabolic Resilience

Gut microbiome interactions, digestive stability, nutrient metabolism, glucose and lipid regulation, and metabolic adaptability.

Immune & Inflammatory Balance

Immune function, inflammatory signaling, mucosal defenses, and the regulation of age-associated immune changes.

Oxidative & Mitochondrial Resilience

Cellular energy metabolism, mitochondrial function, oxidative balance, and physiological responses to biological stress.

Structural & External Integrity

Muscle, joints, skin, coat, connective tissues, and other structural systems that contribute to functional health and quality of life.

Cellular & Molecular Maintenance

DNA and RNA maintenance, epigenetic regulation, proteostasis, cellular turnover, telomere-related biology, and other molecular processes associated with aging.

CGI EVIDENCE PROCESS
How CGI Approaches Canine Healthy-Aging Science
CGI uses a structured process to connect biological questions, measurable endpoints, scientific evidence, and responsible interpretation.
Define the Biological Question
Start with a clearly defined aspect of canine healthspan, aging biology, or nutritional physiology.
Select Relevant Measures
Identify functional outcomes, biomarkers, multi-omic endpoints, and study designs appropriate to the question.
Evaluate the Evidence
Examine methodology, population, controls, effect size, limitations, publication status, and reproducibility.
Interpret With Restraint
Distinguish established findings from supporting, exploratory, or hypothesis-generating evidence and communicate uncertainty clearly.

NUTRITION THROUGH THE CGI LENS
Nutritional Strategies in Canine Healthy Aging

Nutrition may interact with aging biology through multiple pathways, from metabolic and immune regulation to cellular maintenance and functional resilience. CGI evaluates nutritional categories according to biological rationale, available evidence, measurable endpoints, and the limits of current knowledge.

CGI EVIDENCE FRAMEWORK

From Biological Rationale to Replicated Evidence

Not all scientific evidence carries the same weight. CGI evaluates canine healthy-aging and nutritional research according to study design, biological relevance, population, endpoints, reproducibility, and publication status.

01
FOUNDATION

Foundational Biology

Established biological mechanisms and reference knowledge that define plausible scientific questions.

02
PLAUSIBILITY

Preclinical Evidence

Laboratory and model-system findings that may support biological plausibility but do not establish outcomes in companion dogs.

03
CANINE RESEARCH

Controlled Canine Research

Studies in dogs using defined populations, interventions, controls, durations, and measurable endpoints.

04
REAL-WORLD CONTEXT

Real-World Evidence

Evidence from household dogs that can inform relevance, variability, feasibility, and generalizability under real-world conditions.

05
CONVERGENCE

Replicated & Peer-Reviewed Evidence

Replication and peer-reviewed publication provide stronger support for broader scientific conclusions.

Evidence strength increases through convergence—not through a single biomarker or one study.

CGI considers the totality of evidence, the quality of individual studies, and the limits of interpretation before drawing broader conclusions.
