A hotdog is a specific type of soft sausage inside a bun. If you have just the sausage part you would not call that a hotdog (at least not where I live) but a frankfurter (we have a special word for this type of sausage).
The bread needs to be a certain shape as well. Long round and thin. Either one where it goes in from the top (sliced by length)
like this or pushed in the same way as the longer axis of bread goes like this
.
If you put it inside two slices of bread you made a frankfurter sandwich. So thus it needs to be the right sausage in the right bread to be considered a hotdog.
I will fight you on this.
