Canned goods: Most expiration dates on foods in cans range from 1 to 4 yearsâbut keep the food in a cool, dark place and the cans undented and in good condition, and you can likely safely double that shelf life from 3 to up to 6 years. Frozen foods: Theyâre much like canned goods: pretty much expiration-proof.
Before purchasing canned dog food, check the best if used by or use by date on the container. If this is hard to find or not there, avoid the food as it is likely a low-quality product. Canned dog food should have a shelf life of two to five years from the date of canning. Because canning is a sterilizing process, undamaged canned food can potentially last much longer, but it's best to throw it out if it is past the use by date.
