    Almost everyone agrees on the hot dog basics: a long bread roll with a hot sausage inside it. And that’s what has led to a big question — is a hot dog a sandwich, or is it in a special category of its  own?

“People have really strong opinions on both sides,” says Eric Mittenthal, president of the National Hot Dog and Sausage Council (NHDSC). In November, the council published an official announcement ruling that the hot dog is not a sandwich. It argues that the hot dog is too significant to be considered “just a sandwich.” The council admits that the hot dog was once the “Frankfurter sandwich,” but says that people no longer use that name. Today, no one would call a hot dog eating contest a sandwich eating contest.

But others disagree. The U.S. Department of Agriculture (USDA) includes a sausage inside a bread roll in its sandwich category. But it also calls the food a “sandwich type product”. In May, dictionary publisher Merriam Webster said that the hot dog is a sandwich. The Merriam Webster’s Collegiate Dictionary, 11th Edition, defines a sandwich as “two or more slices of bread or a split roll having a filling in between” or “one slice of bread covered with food”. The announcement fueled a heated debate among hot dog fans. If hot dogs are sandwiches, where do you draw the line? Are burritos (玉米馅饼) sandwiches too?

This debate won’t stop Americans from eating piles of hot dogs this summer. During peak hot dog season — from Memorial Day to Labor Day — Americans will eat about 7 billion of them. That’s  818 hot dogs consumed every second. People love hot dogs so much that in 2015, a hot dog emoji was released so people can easily tweet or text an image of the famous food. This may come in handy soon, since July is National Hot Dog Month.
