Puppy dog in REM sleep (kinda creepy) HD

Our normally adorable 8 week female Boston Terrier puppy in REM sleep. Kinda creepy. Some paw twitches. Her face and tongue twitches oddly starting around @0:50 as if she is dreaming of biting or eating something. REM sleep is Rapid Eye Movement Sleep. (Wikipedia: http://en.wikipedia.org/wiki/Rapid_eye_movement_sleep) Apologies for the radio & aquarium water sounds in the background.
