Chili dogs are hot dogs with chili sauce. They are the favorite food of Sonic the Hedgehog in several continuities, particularly the various TV series (Adventures of Sonic the Hedgehog, Sonic the Hedgehog and Sonic Underground). Chili dogs are an interesting (and somewhat rare) example of a staple from the comics and cartoons "bleeding" into the games.
Recent games from the series have also made reference to chili dogs as Sonic's food of choice. In Adventures of Sonic the Hedgehog, Tails also liked chili dogs, but preferred his with extra cheese. Additionally, Breezie likes chili dogs but she only eats the ones prepared by Chef Charlemagne.
Other types of hot dogs also appear. For example, in Sonic Underground, Sonic's sister Sonia the Hedgehog likes to eat hot dogs with tofu, much to her brother Sonic's disgust.
The earliest canon reference to Sonic's enjoyment of hot dogs (rather than the more specific chili dogs) seems to be in early issues of Sonic the Comic. In Sonic the Comic #5, Sonic sits down to eat 300 hot dogs and 100 thick shakes as the second course of breakfast (the first course of which consisted of 200 hamburgers, much to Tails' disgust). However, this doesn't seem to be much of a problem to Sonic since it can be implied that he can burn off the calories with his running (narrowly avoiding the fact that it would be impossible, even for Sonic, to eat all of the food in a single sitting).
There is also a reference in Sonic the Hedgehog #0 which depicts Sonic and his uncle operating a chili dog stand, indicating that the love of the chili dog might well be a family affair.
In a story in Sonic the Hedgehog #11, Sonic eats a bunch of chili dogs as a birthday present to himself, then has a food related nightmare where he is a chili dog. When Sonic wakes up, Sally Acorn and Tails give him a plate of chili dogs. Sonic at first refuses this present, but then eats them anyway.
In the Sonic the Hedgehog Play-a-Sound book, the plot is that Sonic is racing Robotnik in a scavenger hunt to win 6,000,000 Mobiums, which he says he will donate to charity. In the end, he wins the money and spends it all on chili dogs instead.
In Sonic the Hedgehog #0, Part II, Sonic mentions having a "chili dog break".
Chili dogs make a reappearance in the Sonic Boom television series, where they are once again the favorite food of Sonic, and are among the many menu items sold at Meh Burger. However, Sonic does not appear to be as obsessive over them as he is in other continuities. In the episode "Cowbot", during the scene where Sonic and Tails are helping Eggman build a more powerful defense system, Sonic instead heats up a chili dog in a small oven. In a later scene when Eggman is testing out his new force field, Sonic notices his chili dog from earlier sitting on a rock just outside it. After the doctor reluctantly puts down the barrier, Sonic eagerly runs to get it and hungrily scarfs it down.
- The Japanese manual of Sonic Advance 3 states that Sonic loves chili dogs.
- During the end credits of Sonic Chronicles: The Dark Brotherhood, Sonic briefly mentions chili dogs.
- In Sonic Unleashed, different hot dogs can be bought and won from certain missions, pertaining to the location they are received from. Most stores even sell normal chili dogs, claiming that they're Sonic's favorite. Chip finds them too spicy for his personal tastes, but does admit that they're good. In the instruction manual for the PlayStation 3/Xbox 360 version, it's mentioned that Sonic loves chili dogs. In Eggmanland, there is a green chili dog called the Egg Dog, which isn't appetizing to either character as Chip doesn't like them, and Sonic will only gain 1 experience point from it as opposed to 70 EXP from a normal chili dog, but this could be due to the ingredients used and how bad Eggmanland's food is in general.
- In the first cutscene of Sonic and the Black Knight, after Merlina the Wizard summons Sonic, he falls from the sky with two chili dogs. After catching the chili dogs, he looks up to notice the Black Knight. He then eats one of his chili dogs, throws the other in the air. Then Sonic attacks and defeats the Knights of the Underworld, just before the chili dog falls on the ground. Minutes after trying to stop the Black Knight with the whirlwind Merlina created, Sonic's chili dog flew away to an unknown location, much to his disappointment. They can also be found as a food item during the game, with the description calling them "Sonic's favorite".
- In Sonic & Sega All-Stars Racing, under Sonic's profile, it says that he likes chili dogs.
- In Sonic Generations, Sonic is given a chili dog as a birthday present (wrapped in a bow, no less). However, it is the first thing that is blown away when the Time Eater appears, right after Sonic takes his first bite. Also, when his friends were staring at the Time Eater, Sonic was still looking for his chili dog. In the ending, it flew back into his hands, and Sonic took another bite and remarked that it was still warm.
- Though they do not make a physical appearance in the game, a reference to chili dogs appears in Sonic Boom: Rise of Lyric during the side-quest that involves Sonic and co. stopping robots from destroying Chef Woody's food supply. While talking to the chef, he exclaims: "Look at me...I am explaining myself to these creatures that probably live off of chili dogs." They are later referenced again when Sonic humorously adds chili dogs as one of the more important things in life.

- As seen in a picture below, there is a scene in Adventures of Sonic the Hedgehog episode "Boogey Mania", where Sonic is shown making a chili dog while wearing an apron and toque (traditional hat worn by chefs). Interestingly, in that scene, he has no gloves on. He is also shown inspecting chili in his 'chili dog inspector' disguise (suggesting some spicier chili instead of the kind Grounder was cooking) before being turned into solid stone by the Super Supreme Stopper Zapper.
- In the Sonic Sez segment of "Too Tall Tails", Sonic mentions that he likes eating chili dogs but he also likes eating healthy as well.
- Sonic and the Black Knight is one of two games that shows Sonic eating chili dogs. The other is Sonic Generations, in the first and penultimate cutscenes, as well as its manga, where both Sonics are seen eating chili dogs.
- A query was asked in the Sonic Universe fan-mail service and published in Sonic Universe #4. A comment was stated "We don't see Sonic eating a lot of chili dogs anymore. What gives?" It was replied: "He's been too busy saving the world to dwell on dinner! But don't you worry—he's scarffin' down plenty behind the scenes".
- The cover of Sonic Super Digest #7 shows Sonic in his Super form about to eat a large number of chili dogs. Tails notices and (in a reference to the magazine's title) says, "Wow, Sonic! You'll need to go Super to Digest all those chili dogs!"
- In Adventures of Sonic the Hedgehog, Tails' favorite food is also chili dogs, just like Sonic, only he prefers his with cheese.
- A commercial for Mario and Sonic at the London 2012 Olympic Games features an alternate ending where Sonic apparently ordered a chili dog.

- Throughout the many appearances of the chili dog, Sonic is shown to eat them in a variety of ways. In Sonic Underground, Sonic is mostly seen tossing them into his mouth and swallowing them whole, (though there was one instance where he ate most of a chili dog in one bite before eating the last bite a few seconds later). In Sonic and the Black Knight, Sonic stuffs the chili dog into his mouth and actually chews it before gulping it down. And in Sonic Generations, he eats his birthday chili dog one bite at a time and does not eat it very fast.
- During 2012 Tokyo Joypolis' re-opening, Sonic the Hedgehog has been promoting Chili Dog serve food at the mega-arcade with the cost of 300 yen.
