Glenda, it is a corn dog in the US. Pretty much anything fried, and especially anything fried AND on a stick, originated in the US.

We are masters of taking something unhealthy--like a hot dog, or cheese, or a Snickers Bar--coating it in high-fat batter, and deep frying it ... thereby performing the near-impossible feat of making it even worse for you to eat.
God Bless the USA!
But, that thing called an 'American Hotdog?'I swear to god I've never seen anything like it in the US.
Hot dogs, in my experience, come in four kinds: the classic, the Coney Island, the chili dog, and the Chicago.
The classic is a dog on a bun with mustard and relish and onions and maybe sour kraut. Anyone over the age of 12 who puts ketchup on a hot dog is disgracing themselves. The Coney Island is a miniature hot dog (not like those little sausage things you can get here--short, but not fat) on a little bun with ground beef cooked with onions and celery salt. The chili dog is a hot dog with chili and possibly cheese sauce, usually a foot-long dog on a long bun. The Chicago is a hot dog with tomatoes, a pickle spear, onions, celery salt, hot peppers, and mustard ... but never ketchup.
