Not much thankfully, ie. if you do not go by its misleading yet interesting name. So, why is this tasty treat called a 'Hot Dog?"
What is it?
A hot dog is a sausage served in a sliced bun. It is commonly garnished with mustard, ketchup, onions, mayonnaise, relish or sauerkraut.
Why the name?
The term 'Hot Dog' was first coined by cartoonist T.A. Dorgan around 1900 in a cartoon recording the sale of hot dogs during a New York Giants baseball game. He drew a 'dashund' between a split bun to give a humorous twist to the word 'Dog' used for sausage in his era. It is said to echo a 19c. suspicion (occasionally justified) that sausages contained dog meat.
