No food should go unrefrigerated for more than two hours, including Hot Dogs. It's best to refrigerated them as soon as possible. If they are left out longer, they should be thrown out, as they may be unsafe to eat.

As with any potentially hazardous food, these should not be unrefrigerated for more than two hours - or only one if the ambient temperature is quite warm.
