What are hot dogs?
A hot dog is a specialized sausage, served on a soft roll or bun. Hot dogs are known by various names in different cultures, but many have borrowed the English term “hot dog” to refer to a sandwich made with a sausage. In general, hot dogs are slightly smaller than a conventional sausage, in addition to being less spicy. Hot dogs are also cooked before they are packaged for sale, and technically can be eaten straight out of the package, although most consumers warm them up first.
