HONOLULU - Media have carried many stories about American troops adopting abandoned, injured and tortured dogs.

In one case, a dog followed its Marine protectors from one base to a new one, finally being taken in by one of the Leathernecks who ultimately brought the dog home to the United States.

Today, Marine officials are investigating a different kind of dog story - an Internet video that purports to show a Marine throwing a puppy off a rocky cliff.

Video: Video apparently of Marine throwing pup off cliff leads to probe

Maj. Chris Perrine of the Marine Corps Base Hawaii says it appears the man is based with a unit in the islands.

Marine officials are calling the YouTube video "shocking and deplorable" and say it violates "the high standard we expect of every Marine."

The low-quality video shows two Marines joking as one holds up what appears to be a motionless black and white puppy, which he then hurls into a rocky gully.

A yelping sound is heard as it flies through the air.
