A "hot dog" may sound weird at first, but it's actually a sausage sandwiched between a long piece of bread. This is a popular fast food in the United States and Canada. The origin of "hot dog" is also very interesting.

It is said that "hot dog" originated in Germany. The German name is frankfurter (Frankfurt sausage), which is named after it is in the German city of Frankfurt (Frankfurt). It was originally made by a butcher in Frankfurt, who minced pork and beef and stuffed it into sheep intestines. Because of its good ingredients, this food has good color, shape and taste. It was later introduced to the United States and became very popular. In 1904, the Louisiana Fair in the United States attracted many spectators. At noon, people flocked to a hot sausage stand named Anton to buy food. The hot sausages were freshly fried from the pot and were hot and hot. Anton was quick to think and rolled the sausages in long bread to sell them. It was not hot and very delicious. For Westerners who were very concerned about timeliness, the fast food industry was in the ascendant. The "hot dog", a sausage-stuffed piece of bread, has become a popular economical fast food all over the world.

The naming of "hot dog" also illustrates the preference of British and American people for dogs. They believe that dog is a symbol of "loyalty" and "reliability", so we often hear others praising dogs.
