  • Been using this food for years

    By on

    I have been using IAMS dog food for years. I used to show and breed my dogs and this food really made a difference in their coat. It was always nice and shiny without having to give them any extra supplements. I also fostered for several rescues and rather than feed the rescue dogs the food from the rescues, I chose to feed them what I feed my own dogs. They always have nice solid stool and fewer than with other breeds. Being older now and having to buy several large bags a month, Chewy has become a lifesaver for me. It's so nice to have the food delivered for less than I would pay at the store.

  • Product great, shipping speed great, packaging not so much!

    By on

    First time ordering.....impressive delivery speed, and love the no delivery charge. However, when the dog food arrived, the box of treats I had also ordered had ripped the bag and I had 38.5 pounds of dog food all over the box. Very disappointing!! Seems to me that would have been an easy fix so I didn't have such a mess!!

  • Love that food

    By on

    My 15-year-old australian shephard and 10-year-old golden lab love the Iams dog food. Looks like they gained a little weight, so my next purchase may be a healthy weight food for older dogs. My order arrived in 2 days. That was fantastic.

  • Happy HAPPY!

    By on

    Their prices are wonderful & quick to deliver. When I go to the store they don't always have both types (like to mix the small & chunks together). Here I order each. I've been feeding Iams over 30 yrs & their food is so much fresher, I highly recommend using Chewy!

  • Good Food/Healthy Dogs

    By on

    I wanted a more healthy food for my dogs and I tried this brand. I have been using this brand for awhile now. When I take my dogs to the vet they tell me how healthy my dogs are and that their coats look great. I love ordering through Chewy because it is very easy and I get a great price and I don't have to worry about carrying heavy bags of dog food in and out of my car!

  • Just what we needed

    By on

    First time ordering dog food online, but with three large dogs this is way more convenient than lugging a bag! Shippment arrived just on time and I have 3 happy furbabies! So glad we decided to go this way! Looking forward to our next shipment!

  • Good product

    By on

    I ordered online and two days later I received two huge bags of dog food delivered to my door. I didn’t have to buck it into and out of a cart or my car. It is identical to what I buy at brick and mortar but a hundred times easier. Thanks!

  • IAMS FOOD for 15+ years

    By on

    I have been feeding this to my dogs for probably 15 years. Every pup I've had eats this after becoming an adult dog and have never had any problems. Every vet check up they're healthy and at a good weight from feeding them the recommended amount. Also, I always get compliments on how healthy and shiny looking my dogs fur is. The delivery came exactly when expected, packaging was perfect and the food was sealed and fresh. 100% satisfied.

  • One of the best dog food

    By on

    I started out with Aimes years ago, and for some reason we tried several other brands. And as much as I could say that 1 or 2 were good enough, there was no reason to switch away & now that they have the "mini chunks", we are only sticking with Aimes.
