Freezing changes the unit, not just the number
Freezing does not just add time to this item, it changes the unit the answer is written in: 2 weeks in the refrigerator against 2 months in the freezer, 4.3 times longer, months in place of weeks. On the same shelf it sits 5 of 19, between Pastrami at 40 days and Pork roll at 7 days.
Every storage figure the USDA publishes for this item
The USDA rates this item cold or frozen and never at room temperature: no pantry figure exists for it, as for 222 of the 466 foods in the data that get no pantry time at all. Within Meat it is filed under Smoked or Processed.

Can you freeze hot dogs?
Yes. The USDA gives hot dogs 1–2 months in the freezer from the day you buy them, and held at 0 °F food stays safe beyond that: the figure is about quality. Cured and sliced meats change texture once frozen, and the salt in them speeds up rancidity, so the freezer is for weeks, not for keeping.
How to tell if hot dogs have gone bad
Go by the date first: hot dogs keep 1 week in the fridge once opened. Look for a slimy film, a sour smell or mold. A deli package past its window goes out even if it looks fine: listeria grows in the cold without changing how meat looks.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 1 week in the fridge once opened. What decides that is the food: the source files Hot dogs under Meat, a heading it keeps for perishable food. Past it, it is not safe to eat: throw it out without tasting, because bacteria build up while food still looks and smells fine.
The figure in the freezer here is a quality window. The same page carries windows of more than one kind, so which sentence applies depends on which row you are reading, not on the food.
It is past the date. Now what?
Say the calculator above puts Hot dogs past its 1 week in the fridge once opened window, or the container sat out on the counter overnight. Throw the container out without tasting it, and count any hours it already spent out of the refrigerator as part of that window rather than on top of it.
The USDA's limit for perishable food standing at room temperature is 2 hours, or 1 hour when the kitchen is above 90 °F, and that clock runs whatever the storage figure says. Freezing stops the clock but does not turn it back: food already past its window is not rescued by putting it in the freezer. The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.

Where these numbers come from
Every storage time on this page is the USDA’s own published figure from the FoodKeeper data, one of the 9 it keeps per food, reproduced unchanged and never an estimate of ours. Where the USDA lists several kinds under one name, each kind keeps its own windows, and the page names the kind its answer is for. The dates and multipliers are ours, computed from those ranges.
