A danger dog is a hot dog that has been wrapped in bacon and deep-fried. It is served on a hot dog bun with various toppings. Also known as a bacon-wrapped hot dog, it was first sold by street vendors in Mexico. Its origin has been placed in either Tijuana or Hermosillo, where it was originally served in a bolillo instead of a hot dog bun. Danger dogs are now sold by street vendors and in restaurants in urban areas in the United States such as Los Angeles, San Francisco, and New York City. The term "danger dog" originates from this form of hot dog's reputation as being of cheap quality, as it is often sold by unlicensed street vendors.
Francheezie
In Chicago there is a variation of the danger dog called the francheezie. This is an all-beef hot dog wrapped in bacon and deep fried, with melted Cheddar or American cheese. Usually the hot dog is split and filled with cheese before being deep fried. Alternatively the cheese may be added as a topping after frying. The francheezie is served on a poppy seed bun, either "plain" or with the toppings of a Chicago-style hot dog. It is typically sold by restaurants rather than by street vendors.
Bacon-wrapped
In Los Angeles the danger dog is known as the bacon-wrapped hot dog. Vendors can be found cooking them on a stainless steelbaking tray over Sterno heat sources outside of bars, concerts, sporting events, and other late night establishments. The bacon-wrapped usually consists of a bacon-wrapped hot dog, grilled onions and bell peppers, ketchup, mustard, mayonnaise, and grilled jalapeño peppers. After a public campaign in 2010, the L.A. City Council proclaimed the bacon-wrapped to be the official hot dog of Los Angeles.
In San Francisco the bacon-wrapped hot dog is called a Mission dog, named after the Mission District where it is sold. It is typically served with grilled onions, mustard, ketchup, mayonnaise, and jalapeños.
The Texas Tommy is found in Philadelphia and elsewhere in Eastern Pennsylvania. Like a francheezie, it is a hot dog that is split and filled with cheese before being wrapped with bacon. The Texas Tommy can be either deep-fried, broiled, or grilled.
