National Hot Dog Day takes place on July 23, 2017. The day is designated by the National Hot Dog & Sausage Council in the USA. As the name suggests the festival revolve around eating hot dogs, but usually there are many other activities such as wiener dog races, root beer chugging contests and face painting.
A hot dog is a fully cooked sausage, traditionally grilled or steamed. It is typically served as a sandwich in a sliced bun, as a corn dog dipped in corn batter and deep fried, or as an ingredient in other dishes like beanie weenies, or Pigs in blankets. It is often garnished with mustard, ketchup, onions, mayonnaise, relish, cheese, chili and/or sauerkraut. (With material from: Wikipedia)
