If the hotdogs are skinless (like Franks) you need to give them shallow slashes every inch or so or you'll end up with shriveled, leathery things.
If the hotdogs are brats or otherwise have a natural casing then you can grill them directly, but there's a chance the casing will burst and you'll lose some delicious juices. A better way is to let the dogs boil in a flavorful bath, then quickly sear them.
To make the dog bath, take a turkey pan or otherwise foil tray and fill it with a can of beer and Sabrett Onions in Sauce, or any sauce you like. When this bath starts to boil on the grill, add the hotdogs and let them cook for 10 minutes. Then take them out and sear directly on the grill for 1 minute.
When the dogs are almost done, place a bun directly over the dog to catch some meat juices and toast on the the edges.
For some variations, try wrapping the hotdog in bacon before grilling, glazing with teriyaki sauce and topping with grilled pineapple and more teriyaki sauce. Or you can try more basic variations, like grilled onions and red peppers.
