These guideline amounts are a starting point and your dog may need more food depending upon age, activity, and temperament. In order to reach optimal body condition, you may need to adjust food intake. This represents the total recommended volume of food per day. You should divide the total recommended feeding amount by the number of times you feed your dog per day to get the actual portion size per feeding.

Large-breed puppies, reaching 51 to 90 lbs. at maturity, should transition to IAMS Adult Large Breed formula at 12 months of age. Giant-breed puppies, over 90 lbs. at maturity, should transition to IAMS Adult Large Breed formula at 24 months of age.

Remember to have clean, fresh water available for your dog at all times.

Because IAMS Adult Large Breed dog food is complete and balanced for adult dogs, you do not need to add vitamin or mineral supplements.

When introducing IAMS dog food, gradually mix it with your dog's current food over the course of 4 days.

Replace 1 1/4 cup (124g) for each can of Iams with Chicken and Rice (375g can).

IAMS PROACTIVE HEALTH Adult High Protein Large Breed Dry Dog Food with Real Chicken lb Bag is rated 4.6 out of 5 by 242.
Rated 5 out of 5 by from Great food! A good quality food really makes a difference. My dog hardly sheds, has a nice healthy coat and strong muscles. He loves the food. I've switched all of my animals to Iams products because of the great results I got with the large breed formulas, puppy and adult. My diabetic dog is on the healthy weight and my cats are on the digestive health. I have had great results with all 4 Iams products that I have used.

Rated 5 out of 5 by from Going strong My dog is a Belgium Shepard about 65 pounds and has eaten Iams all his life. He just turned 14 and is doing great and taking 3 mile walks most days of the week. I would highly recommend this food.

Rated 3 out of 5 by from Question on label Why does this dog food label say no fillers when there’s corn and barley that is a filler also by products?

Rated 5 out of 5 by from Improved health My boxers have been on this food for a couple of months and I've seen a huge improvement. The 9 year old has needed help getting in my truck for the last couple of years. Now he jumps right in like he did when he was a puppy. His arthritis seems to be all but gone.

Rated 5 out of 5 by from My Rottweiler Loves it! Adopted my Rotti & he was in bad shape! Put him on this and he started looking healthy and his stomach problems went away. I just wish I could find the 40 pound size bag at Walmart. I have to order online which costs me quite a bit of money..

Rated 1 out of 5 by from Most recent bag made dog sick Have been buying iams for years, for a passed dog, and for my current dog.Bought a bag 2 days ago to replace the last and the food has made my dog very sick.It became so bad that the dog is not able to keep even water down. The time between vomiting has increased but am still waiting to see if its passed. This is after only 3 servings from the new bag, where 2 of the 3 had vomit occur afterwards.Same exact type and brand of food, 2 very different results

Rated 4 out of 5 by from Nutritous and good I have two dogs. One is a 12 pound Maltese mix and the other is a 50 pound Wheaten. They both love this food. Yes, I know the Wheaten isn't a small breed but I'm not going to try and feed them different food. I just go for the common denominator.I pay attention to ingredients; just because the dogs may like something doesn't mean it's good for them. The first ingredient in this product is chicken, then chicken by-product meal (i don't want to know what that is), corn meal, sorghum, beet pulp, chicken fat, then a bunch of things I can't pronounce or spell and finally some added vitamins like A, E, and calcium.I'm fine with the ingredients and the dogs love it.
