Is a hot dog a sandwich? If so why or why not?

"Those who voted for a hot dog being a sandwich are not without support. The U.S. Department of Agriculture (USDA) describes a sandwich as “a meat or poultry filling between two slices of bread, a bun, or a biscuit.” By that definition, sure, a hot dog is a sandwich."

Yes

Explanation:

Because The name "frankfurter" illustrates the hotdog’s German heritage — the original came from Frankfurt, Germany, based on a similar pork sausage. There was a suspicion in the 1800s that they were made from dog meat, which is where hotdog came from. If someone calls you a hotdog, they mean you're a daredevil or a risk-taker. Also, you can say “hotdog!” to express delight, kind of like “woohoo!” Hotdog! there for an Hotdog owned Subway
