The IAMS Nutritional Difference
IAMS asks you to try their dog food and look for the visible differences their food can make. The difference you'll see in your pet's health comes directly from the nutrients and vitamins you're putting into his bowl every day. IAMS is formulated with premium protein, a unique fiber blend and a customized mix of protein and carbs. The result is a diet that promotes skin and coat health, supports digestive health and gives him energy for all kinds of playful moments.


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.


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. IAMS includes vitamins A, E, C and B2, as well as biotin, zinc, copper and fatty acids from fish oil to nourish your dog's skin and help his coat flourish.

Dogs Really love it !
By KLBishop on Nov 21, 2019
We changed dog food due to one of our male dogs weight gain. You always are concerned about all of your dogs refusing to eat something new.... oh they just love it ! Seem more active as well.

Low calorie food!
By Rachel on Sep 10, 2019
So happy to find a lower calorie over the counter food for my large dog. He is getting close to 100lbs and really needs to be 90lbs. He's been on prescription diets before but they are so expensive. Happy to find a cost effective alternative. Not as low calorie as the prescription diet but it's better than regular dog food which was making him fat because: old dog = slow metabolism. But now I can continue to feed him 3 cups a day instead of cutting him back to 2 cups a day. Which would have made us both sad. Happy dog, happy owner!

He likes it!
By funnybunny on Oct 21, 2019
I am changing my Goldie's food. He is too chunky. The change from his previous food to this one is going good. He has not had any problem with eating the new choice. I hope that this will help us with his weight.

He seems to like it!
By Cher on Jul 16, 2019
We changed Clarence's food because his was on the list of foods causing heart problems. His did not have any of the ingredients that were suspicious, but since he is a golden he already has a tendency for cancer, we figured he didn't need any chance for heart problems. We ordered large breed weight control and he seems to love it. He looks slimmer and I think his fur and skin look better.

Our German Shepard/Bull Mastive Loves it!
By Weight on Jul 28, 2019
Our dog weighs 97# with no table scraps. Our vet suggested we put him on a weight controlled food. He loves it! We're still in the process of mixing the new Iams food with his old Ian's food so hopefully this does the trick!

Love the convince!
By Rochelle on Sep 9, 2019
I have 3 large dogs and hate going to the store every 2 weeks to drag big bags of dog food home. I love the price and the connivence.

Perfect for my dogs
By Newfie on Jul 23, 2019
We have 5 Newfoundlands and they love this food. As they started getting older we were afraid they were getting a little chubby so we switched from their IAMS large breed regular food to this and they didn't miss a beat.

Iams was a good choice
By JanA on Jul 20, 2019
AS I was trying to switch foods for my Great Pyrenees since they are no longer puppies, I was suggested IAMS by my vet. Both dogs seem to live the flavor.
