25 In its country of Germany, the hot dog was called the frankfurter. It was named after Frankfurt, a German city. Frankfurters were first sold in the United States in the 1860s. Americans called frankfurters “dachshund sausages”. A dachshund is a dog from Germany with a very long body and short legs. Dachshund sausages first became popular in New York, especially at baseball games. At games they were sold by men who kept them warm in hot-water tanks. As the men walked up and down the rows of people, they yelled, “Get your dachshund sausages! Get your hot dachshund sausages!” People got the sausages on buns, a special bread.

One day in 1906, a newspaper cartoonist named Tad Dargan went to a baseball game. When he saw the man with the dachshund sausages, he got an idea for a cartoon. The next say at the newspaper office he drew a bun with a dachshund inside ---not a dachshund sausage, but a dachshund. Dorgan didn’t know to spell dachshund. Under the cartoon, he wrote “Get you hot dogs!”

The cartoon caused deep interest and excitement, and so was the new name. If you go to a baseball games today, you can still see sellers walking around with hot-water tanks. As they walked up and down the rows they yell, “Get your hot dogs here! Get your hot dogs!”
