If THIS was in the show, the gang would be FAMOUS.

Scooby Snacks
(Scooby Snax) are a fictional food item. They are used as a form of incentive payment for the cartoon characters Scooby-Doo and Shaggy from the Hanna-Barbera series Scooby-Doo and its various spin-offs. College-age fans of the series have long maintained that, given the attraction they hold for Shaggy (a blatant hipster-stoner type), Scooby snacks are actually a metaphor for cannabis. Producer William Hanna had always imagined that a Scooby Snack would taste like some sort of a caramel-flavored cookie. He and Joseph Barbera had previously used the concept of a dog that goes wild for doggie treats in the Quick Draw McGraw series in 1959.

Warner Bros. licensed Scooby Snacks as both an official brand of doggie treats and as a human-consumable cookie snack. Vanilla wafers, similar to Nilla Wafers were packaged and sold as Scooby Snacks in Suncoast home video stores.

In Scooby-Doo! The Mystery Begins it is revealed that Shaggy made up the recipe which includes sugar, flour, dog kibble for texture, and other ingredients.

The official brand of dog treats is made by Snausages, a product of Del Monte Foods.
