Active dogs thrive on diets high in fat. To preserve a high-fat dry kibble diet, however, is a challenge. The IAMS research team met that challenge with an effective preservative system used in all our dry dog food products, such as IAMS™ ProActive Health™ Adult MiniChunks.
The preservative system features a special blend of mixed tocopherols. Tocopherols are antioxidants extracted from vegetable oils. There are four major types of tocopherols. Vitamin E, also known as alpha-tocopherol, is commonly used in dog foods, though a specific mixture of the different tocopherols protects against rancidity.
Our preservative system slows the rate of oxidation and allows for an extended shelf life.
Wet foods, such as IAMS™ ProActive Health™ with Chicken and Whole Grain Rice Pate, do not require preservatives because they are preserved by packaging. When the ingredients are mixed and ready for cooking, the mixture is packed into cans, trays or pouches and cooked in a retort. Similar in principle to a pressure cooker, the retort sterilizes and preserves the product.
The cans, trays or pouches are then cooled under conditions that assure product sterility and container integrity.
Thorough shelf-life testing is conducted on all our products. In general, shelf lives for various types of products are:
24 months for wet foods
16 months for dry foods
12 months for biscuits
By using a preservative system in our dry dog food and preservation through packaging in our wet dog food, IAMS makes sure the food your dog eats is well-balanced and nutritionally beneficial.

By now we all know obesity is unhealthy—for both people and pets. But do you know just how many health problems it can cause for your dog? Diabetes, bone and joint damage, decreased liver function, heart disease, increased blood pressure, and a heightened risk of cancer are just a few of the serious health issues caused by obesity. That’s a scary list. Protect your pooch by taking a proactive approach to keeping the pounds off. Here are some ways to do it.
Dogs do better with a controlled amount of food on a schedule. While some dogs can handle eating from an always-full and ever-present dog bowl, most will overeat if food is always available.
There are lots of dog foods out there, all offering something different. When it comes to keeping obesity in check, IAMS™ ProActive Health™ Adult Weight Control and IAMS Healthy Naturals™ Weight Management with Chicken formulas are great choices.
Your dog’s your pal, so it’s difficult not to share your tasty bacon or a bite of steak with him when he gives you those big, pleading eyes. But trust us—it’s worth it to resist. Feeding Fido “people food” ups his food and fat intake significantly. Plus, it creates bad habits: A dog that’s not fed from the table won’t learn to beg.
Obviously, a great way to keep your dog trim and fit is with some good exercise sessions. When you don’t have a lot of time, do short sessions of fetch or tug-of-war. Take it to the next level by jogging with your dog, tossing the Frisbee®, or starting agility training. And here’s a bonus: A dog that gets enough exercise is less likely to act out.
Of course you want to reward your dog when he’s good—but don’t forget that those treats can add up. Pay attention to the calorie and fat content of the treats you give. More importantly, take note of how many goodies you’re doling out—and how often.
Most of the time, a dog is overweight because he’s taking in more calories than he’s burning. But it is possible that there is a larger problem at work. If you’ve tried maintaining your dog’s diet and increasing exercise and still aren’t seeing results, talk to your veterinarian about a possible thyroid or other metabolic disorder.
Don’t get discouraged if you slip up every once in a while or don’t see results right away. Battling obesity is done day to day—it’s about forming good habits and being disciplined. By following the tips above and showing a little dedication, you’ll be on your way to having a healthier, happier dog.
