The term "dog" has been used as a synonym for sausage since 1884 and accusations that sausage makers used dog meat date to at least 1845.
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. These sausages, Frankfurter Würstchen, were known since the 13th century and given to the people on the event of imperial coronations, starting with the coronation of Maximilian II, Holy Roman Emperor as King.
Coney Island, German immigrant Charles Feltman began selling sausages in rolls.
Others have supposedly invented the hot dog. The idea of a hot dog on a bun is ascribed to the wife of a German named Antonoine Feuchtwanger, who sold hot dogs on the streets of St. Louis, Missouri, United States, in 1880, because his customers kept taking the white gloves handed to them for eating without burning their hands. Anton Ludwig Feuchtwanger, a Bavarian sausage seller, is said to have served sausages in rolls at the World's Fair–either the 1893 World's Columbian Exposition in Chicago or the 1904 Louisiana Purchase Exposition in St Louis–again allegedly because the white gloves he gave to customers so that they could eat his hot sausages in comfort began to disappear as souvenirs.
