SEX, STERILIZATION AND METABOLIC PROFILES - Shape Aging Trajectories and Age-Related Disease Risk in Dogs

Sep 29, 2026

The metabolome is an interconnected network of small molecules central to metabolism and signaling, but its role in aging is not well defined. Using the companion dog as a translational model, the study investigates age-related metabolic changes and links them to disease. Machine-learning models trained on longitudinal Dog Aging Project data build a comprehensive aging metabolome, incorporating metabolomics, blood chemistry, and complete blood counts for precision cohorts and extensive demographic, health, and lifestyle data from pack cohorts.

SEX, STERILIZATION AND METABOLIC PROFILES

Shape Aging Trajectories and Age-Related Disease Risk in Dogs

FAQs

Why are dogs used to study aging metabolite changes?

Dogs share a similar environment with humans, develop age-related multimorbidity, and have shorter lifespans, making them suitable for studying aging dynamics.

What data sources were used to model the aging metabolome?

The work uses longitudinal Dog Aging Project information, including metabolomics, blood chemistry, and complete blood counts from the Precision cohort, plus demographic, health, and lifestyle variables from the Pack cohort.

How do sex and sterilization relate to age-related disease risk in the findings?

The results indicate differences in disease risk patterns associated with aging and age-related conditions, including osteoarthritis, and report that no significant sex-based differences were observed while sterilized dogs showed increased risk.
