I can't answer this question but if you haven't made the dressing yet, most food safety guidelines would tell you substitute the raw egg with a pasteurized egg product or coddled eggs. At the very most, 3-4 days in the fridge would be my best guess, like most leftovers.
Okay, found a general guideline for storing raw eggs in the fridge. See http://www.foodsafety.gov/keep/charts/eggstorage.html. Not exact but should give a general idea
