if you notice the first 40 seconds (approx), you can hear an instrumental (Dentist office muzak) of "The Sounds of Silence", (referred to in A-Roid's post)... Every dog I have ever owned, used to alert whenever they heard howling wolves, like this one. My current Dog, a 20lb Tibetan Spaniel goes right up to the TV, puts his feet up on the stand, and stares, head a twisting each way n back; to find the animals. He even on occasions crawls behind the TV to find these critters...
The Dog was hilarious, .... "you shit on the floor this morning", "I am a dog, you are a human fkng being"....... this is why I drink....
