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

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

Because IAMS ProActive Health Mature 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.

Rated 5 out of 5 by from My old guy loves it :) We switched to IAMS Large Breed Mature when our 8 year old Boxer started having more digestive issues. After being on the product for about 6 months now, not only does he like the food but we have less tummy issues to contend with. Will for sure continue to use this variety.

Rated 5 out of 5 by from Better ingredients I was glad that we bought an age-appropriate, breed-size appropriate food with better ingredients for our dog as it does seem to help his digestion and overall well being, so glad we finally did some research.

Rated 3 out of 5 by from Great benefits I received a free sample from PinchMe and my dog seemed to enjoy it. She wasn't any more or any less enthusiastic about eating this food, so although it has great benefits I am not sure I would pay the extra price above the good quality food I already buy for her.

Rated 5 out of 5 by from FANTASTIC FOR MY OLDER DOG I bought this for my 10 year old great dane, who is greyed and looked tired all of the time. He loved the food, which was wonderful and he has so much more energy lately that it HAS to be because he is eating IAMS. I won't switch back to anything else - the changes in his demeanor mean everything to me.
