Girl Eating Hot Dog

Claims about hot dog invention are difficult to assess, as stories assert the creation of the sausage, the placing of the sausage (or another kind of sausage) on bread or a bun as finger food, the popularization of the existing dish, or the application of the name "hot dog" to a sausage and bun combination most commonly used with ketchup or mustard and sometimes relish.
The word frankfurter comes from Frankfurt, Germany, where pork sausages served in a bun similar to hot dogs originated. Wiener refers to Vienna, Austria, whose German name is "Wien", home to a sausage made of a mixture of pork and beef (cf. Hamburger, whose name also derives from a German-speaking city). In German speaking countries, except Austria, hot dog sausages are called Wiener or Wiener Würstchen (Würstchen means "little sausage"). In Swiss German, it is called Wienerli, while in Austria the terms Frankfurter or Frankfurter Würstel are used.
