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 |

Obesity in dogs is a more common problem than you might think. Between 25% and 40% of dogs are overweight, but often, owners don’t realize it until they take their dog to the veterinarian for another reason. Yet even vets can’t tell if a dog is obese by their weight alone. Ideal weight varies by breed, and quite widely within breeds.(Did you know, for instance, that Labrador retrievers, dachshunds and beagles areall prone to obesity?) In short, there’s no ideal healthy weight chart for all dogs!
The good news is that if your dog is overweight, there are a number of ways to help them reach a healthy weight. Don’t underestimate the power of daily walks and a weight management dog diet — IAMS™ Adult Healthy Weight can help return your dog to a healthy weight, providing a path to help keep them fit for life.

Can you feel individual ribs easily? Is your dog’s abdomen slightly tucked up whenviewed from the side? That’s a sign your dog is at their ideal weight.
If you can't feel the ribs easily, your dog has no waist and their abdomen drags,your pup is carrying extra weight. Your veterinarian can help you further evaluateyour dog’s condition and determine their ideal weight.
Dogs gain weight for the same reason people do: They eat more calories than theyuse. Today’s dogs share another problem with their human parents: lack of activity.Many pet parents work all day and are too tired to play with their dog afterward.
Dogs’ metabolisms might slow as they age or after they’re spayed or neutered,which means they require less food. Another common reason for weight gain isfrequently eating high-calorie treats. Sometimes more than one family member isfeeding the dog, and the dog sure isn’t telling!
Other factors that could contribute to canine obesity include:
If you suspect that your dog is overweight or obese, the !rst step is to set up anappointment with your veterinarian so they can evaluate their condition. Likewise,before beginning any weight loss program with your dog, make sure to discuss itwith your vet.
If your dog is overweight, it’s time to implement a weight-management regimen. Ifyou usually feed one large meal a day or keep food available at all times, try adifferent dog-feeding schedule by dividing the daily ration into several small meals— at least two meals a day. It takes energy to digest food, and dividing your dog’sdaily ration into separate feedings will help. If your dog leaves any food in theirbowl, pick it up 30 minutes after each meal.

Your goal is to help your dog be healthier, so select their food carefully. Payattention to the ratio of fat, !ber, protein, carbohydrates and special ingredients inyour dog’s weight-management food:
After your dog reaches their ideal weight, select a maintenance food to keep theirweight steady.
