Whoever had doubts about dogs being the most loyal creatures on the planet should listen to this: a dog named Paco, was found lying in the road in Jacksonville, Florida this Friday, after his owner was fatally struck by a big rig truck. Her loyal friend remained at the scene for four hours, long after the unfortunate woman’s body was removed, reports Fox News.

Paco and his owner Kelly Black were inseparable, says her family, who came and picked him up after the tragic accident.
