A team from the 928th Military Working Dog Detachment will demonstrate how dogs help the military in a May 17 program at the Westport Library.

The military dog team, stationed in Newtown, will be accompanied by author Ann Bausum, who will talk about her books, "Sergeant Stubby: How a Stray Dog and His Best Friend Helped Win World War I and Stole the Heart of a Nation," and her companion children's book, "Stubby the War Dog."

Months after the U.S. had pledged to join World War I, a stump-tailed terrier wandered onto a U.S. Army training field on the campus of Yale University and adopted Pvt. James Robert Conroy as his best friend. The bond carried the pair across the ocean and into the trenches of France, where Stubby became the mascot of Conroy's 102nd Infantry Regiment. Soon he also became a working military service dog, alerting soldiers to impending gas attacks and helping find survivors on the battlefield. He eventually earned commendations on two continents and considerable fame at home, instituting the use of military dogs.

The free library program will begin at 11:30 a.m., and books will be available for purchase and signing. For more information, visit www.westportlibrary.org or call 203-291-4800.
