  • Great Food That Won'T Break The Bank

    By on

    My dog has special needs when it comes to his diet. Iams is great for that! As a student, I don't always have the funds to buy $45+ dog food to tend to his needs, but this does the job! He always eats all of his food, and when I switched from Ol' Roy to Iams, his skin health greatly improved! He no longer gets hot spots, and other concerning things from a poor diet. I always can count on Iams when the budget is tight for a balanced meal for my beloved dog. Would recondmend this for anyone who is also on a more strict budget and looking for something with a decent nurttition and diet. Is it the absolute best? No, but is certainly MUCH better than many other brands. Thank you Iams!

  • Great adult dog food...

    By on

    The only complaint I have is the morsels are larger than any other food I have used in the past. Our dog loves it dry or with a little chicken on it! Never a complaint from him!

  • fantastic !!!!

    By on

    I first saw an ad for Chewy on facebook I decided to give it a try. I did an auto ship to my son as a gift. He was very surprised when a 30lb package arrived. He now will get a shipment every month and my grand-dog Duke is happy too. Next I will get on auto ship for my Boxer Stella. After I found Chewy I told my sister and she now auto ships frozen food for her 2 dogs and is delighted Thanks!!!

  • Great Dog Food

    By on

    My large 120lb dog has to keep her weight very steady due to knee problems. I tried many different brands until I found this Iams. Most importantly she likes the taste. It keeps her energy up and she's full until her next feeding. Her coat is bright and shiny too. This is where the quest for the perfect food for ends. I would highly recommend this dog food to anyone.
