The classic Parisian hot dog comes, as you might expect, in a baguette instead of a bun. The baguette is hollowed out to allow for an oversized dog that's covered in melted cheese.
The Hawaiian Puka Dog is a local favorite. It's made with a special mini loaf of bread that's poked through on one end to make room for unique sauces like pineapple relish, guava mustard, and garlic lemon sauce, and, of course, a hot dog.
Like the hot dogs in Paris and Hawaii, hot dogs in China are fully encased by a round, bun-sized loaf of bread. But the similarities stop there. Chinese hot dogs are smaller than we've come to expect, and the bread is more reminiscent of dumpling dough (or even brioche) often topped with sesame seeds.
Also called a pylsur, an Icelandic hot dog is smothered in pylsusinnep, which is a sweet, brown mustard sauce. Depending on where it comes from, the hot dog can also be topped with ketchup, fried onions, and a mayonnaise-based rémoulade with sweet relish.
Vancouverites are particularly proud of the Japadog, a local street food vendor's take on the hot dog. The menu is wide ranging, but is essentially Japanese flavors (and some outright dishes) on top of grilled hot dogs. The Yakisoba is topped with Japanese noodles, the Oroshi is covered with grated daikon and soya sauce, and the signature Terimayo dog has teriyaki sauce, mayo, and seaweed.
Finding hot dogs in Guatemala is much easier than you might have thought. Mixtos are hot dogs served on tortillas with cabbage, lettuce, and avocados. And then there are shuco dogs ("dirty dogs"), which are hot dogs on a sub-sized roll with guacamole, boiled cabbage, mayo, tomatoes, mustard, and hot sauce.
The completo is a long-loved Chilean take on the hot dog. It starts with a long hot dog in an open bun that's topped with mayo, chopped tomatoes, and avocado. Then, it's smothered with relish, sauerkraut, green chiles, and ketchup.
In South Africa, hot dogs are known as boerewors, and are incredibly popular. They're most often barbecued sausages made from minced beef and pork that are seasoned with nutmeg and cloves, and are served on an open roll. They're usually topped with onions and ketchup.
The original home of the frankfurter, Germany never lacks sausage choices. But the currywurst is one of the most popular incarnations today. It's made of chunks of hot dog smothered in curry-spiced ketchup and a side of fries (often topped with mayo). The bun is either left out completely or is served on the side, somewhat extraneously.
Argentina's answer to the hot dog is the choripán. The hot dog is sliced in half lengthwise before being grilled and served on rustic bread. It's then absolutely covered with chimichurri.
The Chicago-style hot dog is a constant hot topic, if for no other reason than how strict its protectors are about the condiments used on top. Say the word ketchup around a true Chicago-style dog and you'll likely be banned from them for life. The beef frank is encased in a poppy seed bun and is topped with yellow mustard, chopped white onions, sweet relish, sport peppers, tomato wedges, a dill pickle, and celery salt. Full stop.
The Swedish hot dog comes with arguably some of the most bizarre accompaniments. It is usually served in a thin bread (almost like a lavash or pita) that's wrapped around a hot dog topped with mashed potatoes, onions, lettuce, and a mayo-based shrimp salad with paprika.
From the bagel to the hot dog, Montreal dwellers put their spin on everything. A classic local hot dog (also called a "steamie") is steamed (bun and dog), and is served with relish, shredded cabbage, cayenne, and spicy mustard alongside a heap of fries.
Hot dogs in Brazil are nothing if not messy. There are any number of variations on the Brazilian dog (called a cachorro quente), but they are most commonly served in an open bun and topped with red and green peppers, onions, hard-boiled eggs, corn, peas, Parmesan cheese, ketchup, mayonnaise, and sometimes potato chips.
The "Stoner Dog" is an Amsterdam institution and makes no apologies for being exactly what it sounds like — a ridiculous mosh of mouthwateringly bad-for-you flavors that are best eaten… when needed. It is essentially a pizza on top of a hot dog, with pizza sauce, peppers, onions, sausage, cheese, and sometimes pepperoni.
