This is the most heartbreaking thing I've ever seen.  A dog in China won't leave the side of his buddy, who was killed by a car.  Be advised, the video shows images of a dead dog.

Why won't anyone stop and help the poor dogs?  The cars just drive around them.

This isn't the first time a dog stayed by the side of another, hit by a car.  Another video showed the pooch protecting his pal.  This time, someone placed orange cones by the dogs while they called 9-11 for help.
