Looks like it is working!

My 8 year old Newf girl was packing on some weight, so it was time for some action! It has been approx. a month now & I'd say I do already see some weight loss. Another good point is that she really likes this food!

Iams is the best!

I Love Iams dog food. So much better food than most. My dogs love it. I have four dogs and some times they share each others bowels.

Great for my fox red lab

My fox red lab is so much better on the Iams brand then any of the other High dollar foods. He is full of energy!

Need more time

I bought this to help control my dogs weight. I’m not sure if it’s working yet. I switched from Purina Pro Plan weight management which they were on for about 8 months. It was like they were gaining weight rather than loosing or even maintaining! I need more time to see what happens. They do like like the Iams though which is a plus

They like it

Both my senior dog and my adult dog appear happy to eat this food. The kibble size is easy for them to eat. One dog used to scratch alot and that has almost ceased. I have been feeding it for 2 weeks now.

my dogs switched from Hills WD & prefer this!

My dogs like this food a lot! I got the large breed bc 3 out of 4 are large but my Westie has begun to prefer this so I’m here to change breed size only ‘ I’m so glad they prefer a 30$ food yo a 100 $ food! Both are for weight loss.

Tasty dry food

Zoe isn’t a picky eater, (thus the healthy weight food), but she’s never excited about dry food. Sometimes she turns her nose up at it. This is the first time she’s tried Iams and she seems to like it. :)

Maxx Likes It!

We switched to this brand after our dogs started having digestive issues with other food we had used for years. Maxx can be picky so I am pleased that he eats this and doesn't turn up his nose. Also the digestive issues from the other food are now a thing of the past now.

This has been my choice for my Chocolate labs. 7 and 11 years old. Used Iams since they were pups.
