The origin of the name “hot dog” has been widely debated. Here is what the National Hot Dog & Sausage Council has to say about it:
“References to dachshund sausages and ultimately hot dogs can be traced to German immigrants in the 1800s. German immigrants brought not only the sausage with them in the late 1800s, but also dachshund dogs. The name hot dog probably began as a joke about the Germans’ small, long, thin dogs. Ever the butt of humor and rumor, the moniker that stuck was likely a joke regarding the provenance of the tasty sausage served on a bun cut lengthwise.”
The term “hot dog” first appeared “in college magazines in the 1890s. Students at Yale University began to refer to the wagons selling hot sausages in buns outside their dorms as dog wagons. It didn’t take long for the use of the word dog to become hot dog.” The first confirmed printed reference to hot dogs appeared in an article published in the October 19, 1895, issue of the Yale Record which referred to folks “contentedly munching on hot dogs.”
If this little dog could talk, I bet he would say, “Hot dogs are not real dogs!”
