At Penn's Working Dog Center, a first graduating class faces the future with wagging tails

An animal training center inspired by canine rescue work on 9/11 is graduating its first class of working dogs.

The University of Pennsylvania's Working Dog Center held a commencement ceremony Tuesday for a Labrador retriever named Socks.

The canine is going to work for the campus police force performing duties including bomb detection.

Other animals in the class will be working as medical alert dogs or on urban search-and-rescue teams.

The Working Dog Center began training puppies in Philadelphia on Sept. 11, 2012. They are named after canine handlers who worked at ground zero during the terrorist attacks in 2001.
