Raider is Galliher's best friend - and so, naturally, Galliher panicked when the dog disappeared one night.
Galliher and Raider had stopped at a motel in Utah for the night, according to KTLA 5. They were on their way home to Washington state after attending promotion and retirement ceremonies at Marine Corps Base Camp Pendleton in California.
While playing with Raider in the room, Galliher opened the front door for a moment.
That's when the dog bolted.
