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 |

Whether your dog is a big sweetie, a big weirdo or a big athlete, here’s what you need to know about taking care of your big dog.
First, all big dogs start out as little dogs. But pretty soon they grow up — and so does their appetite, their toys, their dog bowls, the vet bill and their need for speed.
He started to grow.
And pretty soon
he was bigger than
the recliner.
Sometimes it can take more than two years for them to reach their full size.
And you won’t like to think about it too much, but their life spans are shorter, too: about 10 to 12 years.
No wonder
you'll let him push
you off the bed
at night.
If a large dog gets too much food as a pup, they’re at a higher risk of growing too quickly, which can cause joint trouble.
For large breeds, being overweight is especially problematic. All that extra weight can be a lot for the joints to carry around.
Keep your good old dog healthy by practicing portion control and feeding nutritious food like IAMS™ Mature Adult Large Breed.
How will she catch
a screaming
15-mile-an-hour
Frisbee in midair
if she has knee trouble.
Back in the day, large-breed dogs were especially energetic. They were working dogs, herders, hunters, cart pullers and people protectors.
Who are we to deny their evolution?
Make sure your dog gets exercise every day.
How do you accomplish this? Walk, walk and more walk. And add in some running, jumping, chasing, hiking, fetching, dog-park visiting, swimming and even agility courses.
Repeat this mantra:
'I am the alpha.'
When it comes to training, think of it this way: The bigger the dog, the harder it is to hide behavior problems. And if you can’t control your super-sized soulmate, they could inadvertently cause damage or hurt someone.
Living large is all
about biting the
wind and living
that sweet,
sweet life.
