How long do opened hot dog packs last in the fridge?

Of course, if you have no plans to eat your remaining hot dogs over a week, you can freeze them. 

Frozen hot dogs are good for up to two months in the freezer when stored in a freezer-safe container.

Now, that doesn't mean you have to toss them at the end of month two, it simply means, that is when they are at their peak quality. 

Frozen foods are safe to eat indefinitely; however, the integrity of the food will degrade over time. 

This could mean on month four when you go to defrost your hotdogs, their texture might be tough or rubbery.

When you are ready to defrost your hot dogs, you want to leave them in your fridge for 24 hours to thaw. 

This is the safest way without any food safety risks; however, if you find yourself in a hurry, you can fill a bowl with water that is cool but not cold
