Storage times and safe temperatures are general guidance from USDA FoodKeeper, USDA FSIS, and FDA sources — they are not a guarantee of safety. When in doubt, throw it out. This is not a substitute for professional food-safety advice.

Hot dogs are already fully cooked when sold, which is exactly why their food-safety profile differs from raw meat — the concern with an opened package sitting too long isn't undercooking, it's listeria potentially growing on the ready-to-eat product during storage, which is why USDA guidance still recommends reheating hot dogs until steaming, especially for anyone in a higher-risk group like pregnant women.
An opened package lasts about a week in the fridge, notably longer than most raw deli-style meats' 3-5 days, reflecting hot dogs' cured composition and the fact that they were fully cooked during processing — a genuine, real difference from raw ground or sliced meat's shorter windows.
Hot dogs freeze reasonably well for a short stretch (1-2 months) without a dramatic quality drop, since their already-processed, emulsified texture doesn't have the same delicate structure to lose that a fresh cut of meat does through a freeze-thaw cycle.
Hot dogs' casings already provide some protection, but an opened package still benefits from being resealed tightly or moved to a container, since exposed ends dry out and pick up fridge odors otherwise.
Hot dogs are fully cooked, which buys them a bit more temperature forgiveness than raw meat, but they still keep noticeably better on a stable interior shelf than cycling through the door's warmer swings every time it opens.
Freezing hot dogs in their original package, with the air pressed out, works reasonably well for the shorter freezer window they have.
Hot dogs are fully cooked before packaging, but that doesn't make them immune to spoilage once opened — a sour smell or a slick surface film means the package should be discarded even if it's within its printed window.
An unopened package of hot dogs actually keeps a bit longer than an opened one even within the same fridge, since the factory vacuum seal protects them from air exposure far better than any reclosing method does at home.
Because hot dogs are pre-cooked, reheating them is mainly about warming through and improving texture, not addressing raw-meat safety concerns — though a package nearing its use-by date should still be heated until steaming as a precaution.

Frequently asked questions
Are hot dogs raw or cooked when sold?
Fully cooked — the food-safety concern with an opened package isn't undercooking but potential listeria growth during storage, which is why reheating hot dogs until steaming before eating is still recommended, particularly for pregnant women or others at higher risk.
How long do opened hot dogs last in the fridge?
About 1 week, notably longer than most raw deli meats' 3-5 day window, since hot dogs are cured and were fully cooked during processing.
Does freezing hot dogs change their texture much?
Less than it changes a fresh cut of meat — their processed, emulsified texture holds up reasonably well through a 1-2 month freeze, without the dramatic quality drop a delicate fresh meat would show over the same stretch.
Why should hot dogs be reheated until steaming even though they're pre-cooked?
Listeria can grow on ready-to-eat processed meats during refrigerated storage even though the product was fully cooked during manufacturing, so reheating until steaming kills off any bacteria that may have developed since then.
