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. These dogs are sold from carts that are ubiquitous along Avenida Revolución and the area surrounding the border in Tijuana, as well as the bar district in Ensenada.
Sonoran dogs are now sold by street vendors and in restaurants and sporting venues in urban areas in the United States such as San Diego, Los Angeles, San Francisco, and New York City.
The term "sonoran dog" originates from this form of hot dog's origins in the Sonoran region of Mexico.
