A "hot dog" is an uncut sausage in a bun, with whatever toppings you see fit. The bun is about the same length as the sausage, and is cut lengthwise, but not all the way through, so that there is a hinge of bread at the bottom.
Usually they are made with a pork or beef sausage. But any meat is acceptable. In this case it is alligator meat.
