Staff Sgt. David Moore was diagnosed with post-traumatic stress disorder (PTSD) and a traumatic brain injury after serving our country in both Iraq and Afghanistan. The effects of PTSD can be about as bad as serving on the front lines: Anxiety, depression, nightmares -- just a few of the symptoms some returning veterans suffer. But many are getting help from service dogs.
Watch the video above to see how dogs like Wilco can change the lives of our American heroes.
You can see more stories of other American heroes being helped by dogs. Robin Meade hosts an HLN Special Presentation, Stories of Courage: K9s for Warriors, premiering on Veterans Day, November 11, at 7 p.m. ET.
