Galliher suspects it was a squirrel that caused Raider to suddenly race across the parking lot before disappearing into the night.
And so began one of the longest nights of Galliher's life. He spent much of it walking and driving and searching for his beloved companion - a dog he credits with bringing him back from the brink of a very dark place in his life.
After his several tours of duty in Afghanistan, Galliher had a difficult transition back to civilian life. Until he met Raider.
"I got Raider when I felt like I felt like I was in a dark cave and there was no chance of seeing the light again and getting him was like having a little glint of hope," he told Fox 13 News.
