Hi, everyone, I'm an English teacher in Italy. My students had asked me why a hotdog has this name...Thank you in advance

The hotdog came by it's name from the cartoonist T.A. Dargan. It seems that in Germany the "sausage" was named the "dachsund sausage" after the butcher inventor who had a dachsund dog. This butcher in Frankfort thought the "sausage" looked like his dog. In 1871 Charles Feltman, the German butcher came to the United States and opened a stand in Coney Island in New York City. Mr. T.A. Dargan, the cartoonist noticed that Mr. Feltman after burning his hand several times handling the sausage started using a milk bread roll to wrap the "sausages" in. Mr. Dargan the cartoonist decided to illustrate this. Mr. Dargan was not a very good speller and could spell "sausage" but wasn't sure of the spelling of "dachsund" so he simply called it a "hot dog". It is said that Mr. Feltman was very successful in his business, selling over 3,000 "dachsund sausages" or hot dogs his first year.
