Abstract excerpt

Frailty is a multidimensional syndrome of aging increasingly studied in companion dogs. Two main operational models have been developed: the frailty phenotype, based on five clinical criteria, and the frailty index, derived from the accumulation of health deficits. Despite their frequent use in human aging research, no comparative analysis of these models has been conducted in canine populations. Baseline data...
