A product code is a series of numbers and letters printed on the outer package of each product that a manufacturer produces to provide information about when the product was made.
As part of the product code, products manufactured by The IAMS™ Company include a 'Best Used By' date, or the date at which the product is no longer considered fresh and should no longer be sold. This date is expressed in “ddmmyy” and “ddmmmyy” formats (line 1 below).
The second line represents company internal information for use in traceability and inventory control (line 2).
Depending upon the production line, pouch products might have code date information in a single or double line.
By recognizing and understanding these codes, customers can make sure they are receiving a fresh product.
Shelf life is the duration, measured in months, during which a product that is stored properly maintains its freshness. This means that if a product has a 16-month shelf life, it is fresh for up to 16 months from the date of manufacture.
The shelf life for our dry dog and cat foods is 16 months. All canned and pouch formulas have a shelf life of 24 months. Biscuits have a 12-month shelf life, and sauce formulas have a 16-month shelf life.
Unopened dry products are best stored off of the floor in a cool, dry place. Open bags of food should be stored in a clean, dry container with a tight seal. Dry products also might be frozen without loss of nutrients.
Opened wet products are best kept refrigerated in tightly sealed containers for no more than three days after the can has been opened. Wet products should not be frozen in unopened cans or pouches. However, wet foods can be frozen if removed from the container, packed in freezer containers and frozen immediately.
There’s no doubt dogs are affectionate creatures. And they have numerous ways of showing it. So what’s the deal when your furry friend comes up and gives you a big ol’ pooch smooch? Let’s take a tongue-in-cheek look into why.

Dogs are oral creatures and gather a lot of information about their surroundings through taste and smell. Maybe you’re salty after a sweaty run. Maybe you’ve got barbecue sauce on your face. “Dogs can smell a lot better than we can,” says Opens a new windowDr. Jo Gale, BVetMed CertLAS MRCVS, Senior Manager, Global Science Advocacy at Waltham Petcare Science Institute, “so they find a lot more things interesting to lick than we can.” This despite the fact dogs only have about 1,700 taste buds compared to around 9,000 in humans.
In a poll* of dog owners, IAMS™ found a large majority (75%) believe dogs lick people to offer friendliness. That’s definitely a correct assumption. Licking has been a social behavior among dogs since the days of great-great-great granddaddy wolf. 'It’s a standard canine greeting to lick others around the face,” agrees Opens a new windowJames Serpell, B.S., Ph.D., Professor of Humane Ethics & Animal Welfare at the University of Pennsylvania School of Veterinary Medicine. “Junior members of the pack will run around and lick the mouths of more senior members.” Your dog considers you part of their pack, so it’s their way of greeting and welcoming you. Or maybe you still have that barbecue sauce on your face.
In ancient Greece, dogs at the shrine of Asclepius were trained to lick patients. In the Middle Ages, Saint Roch was said to have been cured of a plague of sores through his dog’s licks. The French even have a saying, “langue de chien, langue de médecin,” which translates to, “a dog’s tongue, a doctor’s tongue.”

Don’t cancel your health insurance just yet. While dogs’ saliva does have some possible bactericidal properties against some types of bacteria, it can put you at the risk of exposure to others. Too much licking can also reopen the wound and cause further infection. With modern medicine, you’re much better off hitting the first-aid kit.
And that myth about dogs’ mouths being cleaner than humans’? Not true — both contain over 600 types of bacteria. You’re welcome for that image.
While an occasional canine kiss is “aww”-inducing, some dogs can overdo it to the point of annoyance. When this happens, the best thing to do is “completely ignore it and give no attention,” suggests Dr. Jo Gale. “When they stop, provide them with attention.” Over time your dog will learn to scale back on the smooches.
