This photo taken Feb. 18, 2014 shows Lexy, a therapy dog at Fort Bragg, N.C. After three deployments to Iraq and three to Afghanistan, Staff Sgt. Dennis Swols is agitated, prone to bouts of anger and unable to really talk about his time on the battlefield. But sitting in a small office in the Robinson Health Clinic at Fort Bragg, he brightens as his hand drops to the furry head beside him. A 5-year-old German shepherd, Lexy, has ambled over to give Swols a few moments of distraction. (AP Photo/Alex Sanz)
