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.
First of all, before you buy a bag or can of pet food, check for a 'best if used by' date on the container. Higher-quality foods will have this, and the format should be easy to read. Most dry foods have a shelf life of one year, while canned products are usually good for two years from the date of manufacture. Make sure that the pet food you are buying is within its recommended use date.
