Ollie's fresh food will last up to 6 months unopened in the freezer. After you put your packs in the refrigerator, the food will be good to serve your dog for up to 4 days. Always remember to put the food packs in your Ollie puptainer to preserve the freshness of the food. Gently-baked recipes are shelf-stable. However, once opened, Ollie recommends you use the food within six weeks.
