The chili dog, also spelled chili-dog, and chilidog, is an object mentioned in the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing. It is a food product consumed on Sonic's world. It is perhaps best known as the favorite food of Sonic the Hedgehog.
As the name suggests, the chili-dog is a generic name for a hot dog served in a bun and topped with some sort of meat sauce and a spicy substance known as chili.
While trying desperately to get Sonic to rejoin the Resistance, Amy attempted bribing him with the promise of a chili-dog. In an attempt to tease Amy, Sonic accepted the offer. Later on, after saving a town, Sonic jokingly asked for chilidogs when a grateful citizen asked for a way to replay him. When later receiving help from Tails after taking a hit to the gut by Rough's Vapor Condenser, Sonic remarked he had eaten chili dogs that was harder.
