This dog can easily be a descendant of the hugely popular cartoon Courage, the cowardly dog.  

Facebook user Cody Viselli's dog is possibly the most cowardly pooch on the planet. He'll run from anything, from paper towels to a jar of mayonnaise to a tiny screw, reports Mashable.

At least this pup seems like he's good for a laugh because he's not much of a guard dog.
