Dog buries puppy in viral video

A touching moment caught on video, a dog buries a puppy in the sand.

A black and white dog comes across the dead puppy and uses its snout to push enough sand over its body to completely cover it.

The video, posted to YouTube, was said to be shot in Iraq. It is unclear if the dogs are related.

The larger dog takes more than three minutes to cover the puppy before it walks away.
