In the war, Gina was riding with her handler when an IED went off in the vehicle behind hers. It spooked her. Then, the constant patrols, flash bangs, the sounds of kicking in doors and the IED booms got to her.
"When Gina came back from the Middle East she was so messed up, she didn't want to see anybody," said Master Sgt. Eric Haynes, 21st SFS noncommissioned officer in charge of the military working dog section. "She wouldn't walk through front doors, she didn't want to go inside buildings. She was terrified of everything."
