Watch heartbreaking video of dog giving puppy proper burial

TORONTO – Do animals grieve and mourn the dead?  In a heartbreaking video posted to YouTube, it appears a dog does just that.

In the video posted on Sunday, a dog can be seen using its snout to push sand over the lifeless pup in what appears to be an act of mourning as passersby looked on from the side of a roadway.
