Woof Woof is the pet werewolf of Norma Deathman in "Scooby's Peep-Hole Pandemonium", an episode of The New Scooby-Doo Mysteries.
Woof Woof is a short, hunchbacked wolfman with unkempt brown fur and sharp pointed eyebrows. His eyes consist of green sclerae and black pupils.
Woof Woof is the longtime companion of Norma Deathman, whom treats him as a pet. He has been at her side for at least 50 years, and even starred in one of her movies. He's very loyal, although dimwitted, and often sniggers at the events going on around him. He appears to enjoy napping beside the pipe organ in the living room of Norma's mansion.
When the Scooby-Doo Detective Agency infiltrated Norma’s mansion, Woof Woof played sidekick to Norma and joined in the chase to catch the gang.
