It's been three months since the Penn Vet Working Dog Center welcomed its inaugural class of puppies, seven rambunctious balls of energy destined to become highly trained detection dogs performing jobs that range from police and rescue work, to bomb and drug detection.
The dogs—Bretagne, Kaiserin (called Kai), Morgan, PApa Bear, Sirius, Socks, and Thunder—are known as the Class of 2013.
