Healthy Digestion

Healthy Digestion

Getting the right amount and type of fiber is important for your dog's digestive health. IAMS uses a proprietary fiber blend that includes prebiotics and beet pulp. Prebiotics feed the good bacteria in the gut, and beet pulp is a great fiber source that helps the body absorb vital nutrients. Every IAMS recipe is tailored to your dog's nutritional needs with the proper level and right kind of fiber for healthy digestion.

Ideal Energy Levels

IAMS delivers a customized mix of protein and carbs to keep your dog energized and ready for running and playing. Dogs need a diet that's high in animal proteins and fat, with an ideal ration of protein to carbohydrates to maintain a healthy energy level. Dogs on IAMS are getting essential amino acids, plus the amount of carbs they need for fetching toys and retrieving slippers.

Ideal Energy Levels
Healthy Skin and Coat

Healthy Skin and Coat

The best way to keep your dog's skin and coat looking their best is through a complete and balanced diet filled with key nutrients. Vitamins, minerals, protein and fat all play a big role in promoting excellent skin and coat health.

  • Great food

    By on

    Our Bixby beagle loved this new food so much he broke into the big bag and dove into it as far as his fat little tummy allowed, then spent a couple of days on water rations and extra walks before recovering from a feast gone too far. He's now right as rain once again after a scare he'd pop like a balloon. Thank goodness it's low fat.

  • Tubby Puppy?

    I purchased this food for my Australian shepherd pup. Her Veterinarian was very concerned about her weight. Now her weight is down, and she has more energy than ever. Plus, the perk is, she loves the food!

  • Iams Optimal Weight

    By on

    When my veterinarian told me that my fur baby needed to loose some weight, I wasn’ t sure what to try. She had always been given Iams since birth so naturally I tried this. My fur baby loves it. Doesn’t even notice that she has lost weight !!

  • This product works great!

    By on

    I've used this product for many years for my pets. Currently have been feeding my chihuahuas this food mixed with some canned food to help maintain their weight. My little female packed on some pounds this year. She has dropped 2-1/2 lbs and needs to lose another pound or two. Am confident she will successfully lose the remaining weight and keep it off, thanks to this product!

  • Dixie loves her new food

    By on

    I am slowly transitioning my adopted dog, Dixie, to her new food (It was recommended, on a website, that I give her 1/4 of her new food for a week and then increase by 1/4 each week until she is eating only her new food on Week 4). We are in Week 2 now. She has been sorting through her food and only eating the new Iams kibble. I often have to "spike" her former kibble with cheese or cottage cheese so that she eats all of her food morning and night.

  • Hard to Find

    By on

    Our dogs have dined on Iams Optimal Weight for quite a few years. Suddenly I could not find it in any stores anymore. Checked Chewy and there it was and I don't have to load it in the basket or the back of my car!
