Frailty tool in aging dogs digs up new data energizing the maternal cost of reproduction debate: Good news for mothers

Frailty threatens older individuals because it increases their vulnerability to detrimental health outcomes, such as falling, longer hospitalization, or even shortened life expectancy. New research in aging companion dogs exploring the linkage between reproduction and aging shows that production of live offspring did not increase late-life frailty; instead, females with live offspring exhibited elevated robustness later in life.
