Our two larger pups were putting on weight too fast and needed to lose about 5-8 pounds to be back in a safe/ normal range. We've had them on this brand/type of food for about 3 months and both pups are doing much better and have lost most of the excess weight.

My older dog loves this dry food!!! She is blind and very old so she has gotten bigger over the years!!! I love that she is getting the food and nutrition that she needs but it helps control the weight that she can't get off herself!

My dog loves IAMS! She had some stomach issues when she was a little younger but not with this food! She definitely enjoys eating this more than any other food she’s been on. Definitely recommend

Our Rotty has been eating Iams large breed dog food most of her life! She is happy and healthy and full of energy. We recently added another fur friend to our family! She now she too is eating Iams for puppies! Excellent products! Looking forward to many more years with our fur friends! Thank you Iams.

Jax is some kind of mix that we’re not sure about but we do know one thing... he’s short and thick so watching his weight is necessary. We don’t want him gaining anymore so we switched him to this food. He loves it and isn’t picky about it at all.

My father is a truck driver who delivers grease to many dog food companies. Inedible grease, I should specify. Knowing what he knows, this was the only brand he felt comfortable feeding to our dogs. Filled them up and kept their weight under control as well.

Both my dog and two cats eat Iams! We switched to Iams, because of the ingredients and health choices for the pets! The vet had recommended it and it works perfectly for our pets! Would highly recommend to other pet owners!

A great all around food source for my dog. She’s almost a twelve year old female yellow Labrador Retriever. She’s had great health, a beautiful coat of fur and an extremely youthful quality to her demeanor. If that doesn’t tell you something that there is something special about this diet choice, what else would?

This is the only dog food I buy my dogs. The vet told us to put our dogs on a diet and we feed them this now and walk multiple times a day and they have lost weight just like they need to. Thank you Iams! This is the best

Has anyone had issues with this dog food. I had my two dogs on it for 2 years and they lost weight, but developed some problems?

I have two dogs who the vet wants to lose around 10 pounds each for health reasons. Iams is one of the more expensive brands; is it worth the extra money? Does it help with weight loss?
