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.

  • Very good product

    By on

    My Labrador has been eating this for a number of years and it has been easy to maintain a very healthy weight. (Veterinarian's words). My dog has tons of energy and a beautiful coat with no extra effort on my part. I highly recommend this for a large dog that tends to gain weight too easily.

  • Great Product for My Pup

    By on

    We've fed "Large Breed" IAMS to our dogs for years, and now that a little extra weight is coming on with old age, my female lab has readily switched to the "Healty Weight" variety.

    We have a 13 year old boxer. We spent over a year and a half trying to find a quality dog food for her that wasn't just packing on the pounds. I was having to literally cut her portions down to the point she wasn't getting enough to eat but everything was still piling on the weight, no matter how much we cut the portions back. Finally I tried IAMS healthy weight a few years back and she was easily cut back to her healthy weight while still getting enough to eat. Now following the recommendation of rations she's healthy, happy and at an ideal weight. Chewy has made it easy to get it to our door without driving 20 miles to get it. Thanks Chewy!

  • Bo is eating again

    By on

    I love having the large bags delivered. Bo likes the taste because he is eating again. I'll have to see if he still is eating it later. I may have to start buying his food in smaller bags so he doesn't get tired of it before he eats the whole thing.

  • Sorry, not a good one for me

    By on

    I purchased this product for my dog but he absolutely won't touch it. I've tried mixing it with other things and with chicken broth but it picks out everything else and won't eat this food. It is unfortunate that I bought such a big bag because I am going to have to give it away.

    Loved having it delivered to the front door. I just open my front door and slid it down the stairs. I didn't have to take it from the store to the car from the car to the house.
