We humans do all kinds of things to live better and longer, from exercising regularly to supplementing with vitamins.

Taking a page from scholarship in human aging, researchers at the University of Washington are studying what could be done to increase the life expectancy of dogs. Biologist Daniel Promislow and pathologist Matt Kaeberlein at the school have started the Dog Aging Project to understand how dogs age, and to explore how medications could help them live longer. The team is hoping to launch a longitudinal study involving 10,000 dogs from all over the country.

Kaeberlein talks to Patt Morrison about the project, and what he and his team have learned about how dogs age.
