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 |

Worried that your small-breed dog is packing on the pounds? Run your hands along his backbone. You should be able to feel (but not see) his ribs. You also should see a clearly defined waist behind the ribs. If you can’t, follow these seven tips from Debra Eldredge, a veterinarian and co-author of “Dog Owner's Home Veterinary Handbook,” published by Howell Book House.
Before you put your overweight dog on a diet, schedule an appointment with the vet to make sure an underlying health problem isn’t causing the numbers on the scale to creep up.
Snacks and table scraps might account for your overweight dog’s bulging belly, Eldredge says. If curtailing in-between meals doesn’t make a difference, consider continuing with the same amount of food but switching to a different formula. Your vet can give you guidance.
Thawed frozen green beans, canned pumpkin (which is fiber-rich and filling) and cut-up carrots make satisfying, low-calorie snacks for your pet.
A study showed that dogs can count up to six or seven, Eldredge says. If he is accustomed to getting two small biscuits as a treat, break one biscuit into two pieces. By his count, he’s still getting two treats!
As much as your overweight dog loves treats, he also loves taking walks, playing and spending time with you. You also can replace biscuits with a couple of pieces of the kibble he would get during mealtime.
Is your bichon staring up at you with those beautiful eyes as you nibble on peanuts? He’s probably not hungry. As you have your snack, offer him a piece of kibble. If he turns it down, he’s not really hungry — he just wants your peanuts!
If your overweight dog has just a couple of pounds to lose, it can be hard to gauge whether he is making progress. Ask your clinic if it’s OK if you stop in once a week so he can step onto the doctor’s scale.
