LOS ANGELES – Scientists in California say they have cloned a dog that helped with search-and-rescue after the New York terrorist attacks on Sept. 11, 2001.

Five German shepherd puppies cloned from a dog named Trakr have been delivered to owner James Symington, a former police officer in Halifax, Nova Scotia, who now lives in Los Angeles.

Before Trakr died in April at age 16, Symington entered a contest sponsored by the California company BioArts International that offered to clone a pet dog for free.

Symington took Trakr to New York after the World Trade Center collapsed and said Trakr helped find one woman who was still alive.

Symington was briefly in hot water for working at the Trade Center while he was supposed to be on medical leave.
