Of course, cover and refrigerate all opened dog food in tightly covered containers. In fact, I refrigerate or freeze dry food in containers too, if I have the room.
Wet food or dry food soaked in water is good for about 3 days (in my experience).
Just sniff it, you will know if it’s going bad. Dry food without anything added in a tightly covered contained is good for at least 2 weeks, unopened bags are good a lot longer, but check the expiration/best by/use by dates on the package.
