Demon Dog

Demon Dog is a screamer video made by Dane Boedigheimer or known as Daneboe, first uploaded in 2009.

The video begins with a shot of Dane's dog, Charlie, looking around the room, followed by the caption "Charlie Can Make An Angry Face" Offscreen, Dane (who is recording) is attempting to persuade Charlie to make the angry face. It takes a few tries, but as Dane says: "Make that angry face, please. I'm furious!! "Charlie's face turns demonic, and utters out a deep roar before returning to normal. Dane then rubs his head, happy that he successfully pulled it off.
