and Relevance: A paradigm shift toward proactive, lifestyle-centered veterinary care is supported by reframing aging as a dynamic and modifiable process. Promoting individualized, preventive strategies can improve the functional longevity, mitigate frailty, and support quality of life in senior pets. Veterinarians are uniquely positioned to translate lifestyle science into meaningful clinical outcomes across the lifespan.

and relevance: Veterinary geroscience reframes aging as a modifiable process, offering translational insights aligned with the One Health concept. Standardized aging assessments, increased feline-specific research, and international longevity surveillance are needed to refine precision geriatric care. Applying coordinated, data-driven interventions in clinical settings can enhance both lifespan and quality of life in aging pets, with potential to inform human aging strategies.

and Relevance: By aligning geroscience concepts with practical, speciesspecific clinical frameworks, this review provides veterinarians with tools to improve proactive screening, precision diagnosis, and individualized management in aging pets.Applying these findings may extend healthspan, mitigate functional decline, and enhance quality of life in senior and geriatric dogs and cats.
