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.

Rated 5 out of 5 by from Best dog food High quality, great food for your dog! Our nearly 10 year old lab mix, Riley, has only consumed IAMS food her entire life. She has great teeth and keeps up with our 3 year old lab mix, Stella, no problem. She still can walk 5 miles(or more) has strong teeth and just such a healthy dog. I credit IAMS with her happy active life...thank you!

Rated 5 out of 5 by from Exceptional food supporting BRAIN and BEHAVIOUR We recommend this formula to "training and behaviour" clients on a regular basis... it is very similar to therapeutic formulas that aid in behaviour maintenance and the added amino acid, L-Tryptophan is an added bonus as it's a required "ingredient" for the calming chemical "serotonin" in the brain, which helps in supporting a calming effect.

Rated 5 out of 5 by from My Dog's Fav! I've tried many dog foods and my dog would always nibble around and try to find the best pieces of certain brands, but when I got Iams she absolutely loved it and ate all of it without a problem. I highly recommend Iams to any Paw Parent ❤

Rated 5 out of 5 by from Healthy dogs, happy momma! I own 2 mastiffs, one Bull Mastiff that weighs 130 lbs and one English Mastiff that weighs 200 lbs. I have used IAMS large breed for 8 years, once they got past the puppy stage. I used IAMS for puppies prior to that. My dogs are 8 and 9 and are healthy as horses. Mastiffs tend to have quite a few health issues, but not my boys. I do give them joint supplements now that they are older. Everyone always tells me how great they look. They coats are beautiful. I expect to have many more years with my dogs, so thanks IAMS!

Rated 5 out of 5 by from Glad I feed my dog Iams I have fed my dog Iams dog food since he was a puppy. Every time we go to the vet, my vet always asks what dog food I feed him because his coat is so beautiful. I always reply, "Iams". The vet replies, "That is good dog food!."

Rated 5 out of 5 by from Glad I switched to Iams! I switched my bloodhound Bessie to your large breed formula 6 months ago. Her coat is so much healthier. Being a large breed, she sometimes experiences pain in her hips. It has improved also. She loves the taste too!

Rated 5 out of 5 by from dog loves it I rescued a two year old American Staffordshire terrier and at first I tried blue and a couple other brands but everything upset his tummy so when I tried IAMS Large breed (both the mini chunks one and the other one) he loved them both

Rated 4 out of 5 by from Summer 2017 Changes I like the addition of new fruits and veggies, but it looks like more dried brewers yeast and caramel color were added. Why does my dog need food coloring in her food? Can we have the good veggies and fruits without the added colors and brewers yeast??
