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.

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


Because IAMS Mature Adult 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.

Rated 5 out of 5 by from Best thing we have done for our dog! Our 8 year old was having hip problems and limping badly. We took her to the vet ans they prescribed Vetprofen and said "unfortunately labs often have these problems. " Lizzy was no longer able to go for long walks or runs like she was used to doing. By chance at our local grocery store I bought a bag of Iams Mature large breed. 2 bags later it has changed her life! She is back to daily walks and runs at our State Park. And she doesn't need the pain medication!

Rated 4 out of 5 by from Great, but kibbles are too big I'd really love to see this food in a mini chunks version. Small dogs are eating the minichunks now, but they are getting old and really need a mature diet, but these kibbles are too big. :-(

Rated 2 out of 5 by from Chunks too Big for Small Dogs I am very disappointed this dog food no longer comes in a size that small dogs can handle. The big chunks are too big for my dog's mouth. The food itself is fine, but the size is wrong. When will you be bringing back this food in the mini chunks?

Rated 5 out of 5 by from Iams Senior I have a 9 yr old Border Collie.I've changed her food from Royal Canin to Iams Senior. I ran out of my usual RC food and bought Iams till I ordered more, however, I noticed she loved the Iams and licked the bowl all the way round and her coat is a lot more shiny since switching, so I'm going to continue with the Iams. She seems very happy and her stools are easy to clean up too.
