Is Bologna in all hot dogs?

While bologna is a type of sausage, it is a different type of sausage than the one typically used in hot dogs.

* Hot dogs are usually made from a mixture of pork and beef, sometimes with other meats like chicken or turkey. They are typically finely ground and emulsified, giving them a smooth texture.

* Bologna, on the other hand, is a coarser ground sausage, often made from beef or pork, and sometimes with other meats like veal or poultry. It has a more distinct texture and flavor.

While some people might enjoy a hot dog made with bologna, it's not a common or traditional ingredient.
