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 1 out of 5 by from My dog is now Diabetic... So for the past 6 months, my dogs (a 10 year old female maltese and an 8 year old male yorkipoo: both are fixed) have solely been feed Iams Senior dry dog food (purple bag). Well last week a veterinarian diagnosed my 8 year old male yorkipoo with Diabetes Type 1 as well as Pancreatitis. Who knows if the Iams Senior dogfood contributed to this or not, but I quickly stopped feeding my dogs Iams. BEWARE

Rated 5 out of 5 by from My older dogs love it I have two small 10 year old dogs. One has had a lot more energy lately. Always prancing around the house. My other small dog was a picky eater but she eats up no problem. They were having hard poops before also. Now they go 2-3 times a day with ease.

Rated 4 out of 5 by from Best cheaper food Switched from Nstural Balance which is better, but expensive. (Im going through chemo and not working so all of us gave made sacrifices financially.) I was concerned about the change. My dogs didnt like it initially but ate it. I have noticed a slight dulling in the coats and weight gain however they are doing great aside from those minor changes. Theyve been eating it for 3 years now and both are 13, and have energy and playfulness. Its the best cheaper dog food but if you can afford better go with Natural Balance. If not, Iams will take care of them well enough.

Rated 4 out of 5 by from The food is great! The food makes me happy! THE PACKAGING DOES NOT!! What is going on here? This is the most horrific bag to have to get into twice a day. I have to use both hands to keep it open and struggle with the cup I have to dip it out. It isn’t resealable which also stinks. Why do you guys package the food like this?? The plastic is so thick the only remedy I found is cutting the bag in half to get down in it and then my dog can get in it too!! Please change the packaging it SUCKS BAD!!! And it can’t be good for the environment either. My dog Tobias has Lupus but before we knew I searched hi and low for a good for him food that I could afford because I am on a fixed budget. This was the winner. He loves it and it doesn’t irritate his sensitive system. But the packaging is horrible. Brought to make me want to start looking for something else to feed him.

Rated 1 out of 5 by from Nearly killed my dog This made my dog lethargic and lick his lips constantly. Made him burp and beak wind and vomit. He ended up being cut open due to how ill he was. Google the iams mature and upset tummy. Dogs have died. I’ll never ever trust them again. Complaints are on their way
