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

I bought this food for a very long time liking that there are not dyes and artificial ingredients (for the most part) at an affordable and manageable price. The issue I found is that my dog does not love the taste...he much prefers other brands of dog food and I have since switched. The difference is he gets excited for his food now.

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.

Love this for my pup. It helps keep her weight down which is very important to me to alleviate stress on her joints from being overweight. Plus it's cost effective when buying the 13 pound bag.

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

This is the only brand and type my dog has ever used. I don’t feel that there’s any con to using this product they love it. I get this product from Kroger’s. My pets enjoys this product so much and I’m sure my pets would recommend to everyone and so would I.

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?
