Your dog needs antioxidants to help promote a healthy immune system. This is why every IAMS™ dog formula contains optimal levels of these nutrients.
Antioxidants are important naturally occurring nutrients that help maintain your dog’s health by slowing the destructive oxidative process of cellular molecules. IAMS research is advancing antioxidant nutrients for senior dogs — and the benefit is improved immune function.
Discover how the antioxidants in IAMS products can benefit your dog’s health in a number of ways.
Antioxidants are found naturally in the body and in plants such as fruits and vegetables. Common antioxidants include vitamin A, vitamin C, vitamin E and certain compounds called carotenoids (like lutein and beta-carotene). When antioxidants are part of a dog’s complete diet, they can provide the following benefits:
As cells function normally in the body, they produce damaged molecules called free radicals. These free radicals are highly unstable and steal components from other cellular molecules, such as fat, protein or DNA, thereby spreading the damage.
This damage continues in a chain reaction, and entire cells soon become damaged and die. This process is called peroxidation. Peroxidation is useful because it helps the body destroy cells that have outlived their usefulness, and it kills germs and parasites. However, when left unchecked, peroxidation also destroys or damages healthy cells.
Antioxidants help prevent widespread cellular destruction by willingly donating components to stabilize free radicals. More importantly, antioxidants return to the surface of the cell to stabilize rather than damage other cellular components.
When there are not enough antioxidants to hold peroxidation in check, free radicals begin damaging healthy cells, which can lead to problems. For example, free radical damage to immune cells can lead to an increased risk of infections.
Recent research has examined the benefits of certain antioxidants on the immune response of dogs, and the results of these studies indicated that antioxidants are important in helping dogs maintain a healthy immune system.
IAMS adult and puppy formulas contain optimal levels of antioxidants such as:
| Antioxidant | Source | Function |
|---|---|---|
| Vitamin E | Plant oil extract and tocopherols | Optimizes immune system’s T-cell activation |
| Beta-carotene | Vitamin premix, corn meal, chicken by-product meal and chicken fat | Optimizes types of cell present in the blood, increases antibody levels in the blood |

Is your dog really a finicky eater, or could it be something else? There are many factors to consider when you notice that your dog doesn't seem to be eating as usual.
If you're suspicious, take a closer look at exactly what he's eating each day. Does he get the occasional dog treat, or is someone sneaking him extra table scraps?
When you feed your dog a balanced, highly nutritious diet, nothing else is needed. In fact, extra treats can drastically alter your dog's normal intake of dog food. It's similar to the feeling you get after eating too much candy or potato chips. Are you interested in a full meal? Neither is your dog.
IAMS™ dog foods are nutritionally balanced and specifically formulated to meet the needs of dogs in all life stages, and with different lifestyles. There are dry, canned, and pouch varieties, plus options for senior or overweight pets, puppies, and dogs with reduced activity levels. Talk to your veterinarian or an IAMS Pet Care and Nutrition Center professional for advice on what's best for your dog.
Recommended feeding amounts are shown on every package. The guidelines are general suggestions for the amount of food you should feed your dog. Every dog is different and does not need the same amount of food. Your dog's activity level and his metabolic makeup are the determining factors. Start with the amount given in the feeding guidelines. Then, add or subtract food as you observe your dog's eating habits and weight.
Portion-Controlled Feeding: Divide the daily amount and feed at specific intervals. It is important to take away all leftover food after 15 to 20 minutes. This sets a pattern for your dog to follow. The portion-controlled feeding method is recommended for giant and large breeds as well as for overweight dogs. Portion control also works well for dogs with special needs.
Free-Choice Feeding: Feed the daily amount and let your dog eat at leisure. This method is recommended for use only with dry foods. Remember, dogs eat to meet their energy requirements. They quickly define their own daily portions when eating free-choice.
Water: Regardless of which food you choose to feed, your dog must have plenty of fresh, clean water. A good dog feeding tip is to place the water 3 to 5 feet from the food. This will help prevent your dog from gulping water and air in addition to food.
Routine: Dogs need it. Feeding at the same time and place every day establishes a comfortable eating pattern.
