Hot dogs take about five to ten minutes to boil until done. If you have a microwave, you can save some time. Time varies depending on how many hotdogs you want to microwave, I.E. One hot dog, 30 to 35 seconds; two hot dogs, 45 to 55 seconds; four hot dogs, 1 1/4 to 1 1/2 minutes; six hot dogs, 2 to 2 1/2 minutes; eight hot dogs, 3 to 3 1/2 minutes; 10 hot dogs, 4 1/2 to 5 1/2 minutes. But you will want to prep them first by splitting them open and the covering them with paper towels (NOT FOIL) or the like.
Be careful as they will be very hot when they come out of the microwave. Then once you have them cooked, you can serve them as you like. Be sure to remove paper before eating.
