Hotdogs will last for up to 2 weeks in the refrigerator.
Hotdogs should always remain refrigerated until you eat them.
However it's okay to leave hotdogs out at room temperature for an hour or two while preparing to cook them or eat them.
The hotdogs are actually not raw though and all you have to do is heat them up to eat them.
Since the hotdogs are already cooked that makes the hotdogs last longer in the fridge than other meats that are raw.
You an keep hotdogs longer than a few weeks by freezing them instead.
I buy a lot of hotdogs on sale and then freeze them for later use.
I've kept hotdogs in the freezer for 2 years before and they were still good to eat.
