How new research may extend your dog’s life


“We’ve been able to increase lifespan by 30, 40, 50 percent by targeting the pathways that affect aging. Fundamentally, there’s no reason why that can’t be done in dogs,” Kaeberlein says.

Dog lover and biogerontologist Matt Kaeberlein has been experimenting with rapamycin, a drug commonly given to people receiving organ transplants. It helps prevent organ rejection.

But in mice, they’ve also found it does something extraordinary. It improved strength and cardiac function and considerably extended their lives. The “old man” in the mouse group, Ike, is the equivalent of a 140-year-old person.

Some of the canine citizen scientists who have joined the study:


Whidbey is a 12 year old Golden Retriever.


Finn is a 10 year old German Shepherd mix
