Lucca, a military dog trained to locate explosives, lost her left foot and subsequently her leg after one of the devices she found detonated in Afghanistan last year. Despite the violence she's witnessed and suffered, Lucca maintains a loving spirit, according to her handler and now owner, Marine Gunnery Sgt. Chris Willingham. "She's been through a lot. Through firefights, been close to mortars and she was that close to an IED and she's still got the same spirit, same personality," Willingham said. Lucca is now retired, but she and Willingham are traveling with the National Military Working Dog monument before it comes to rest in Texas.
