  • 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.

  • Best value, pet owner of 20yrs.

    By on

    We've had our dogs on various more expensive brands of dog food, and yet they prefer this variety of Iams, which is at a median pricepoint. I have one senior dog and she has maintained a healthy weight on this variety of Iams. Their stool is always formed, and she shows no problems, yet historically has had a sensitive stomach. In that regard I am pleased as well. I have not been paid via free products or stipends for leaving this review.

  • Its Alright

    By on

    My dogs eat this when we are a bit tight on money and cant buy their normal food. Usually its once in a great while so when we do they hammer it but after a day or 2 they are bored and want their old stuff back. I'm not ecstatic about it either but its better than something that's fully processed and no natural ingredients.

  • This is the best dog food for our needs

    By on

    Benny, the Rottweiler, works out running 5 miles 2x a week plus on and off leash work. He is 3 years old, and Iams, doesn't upset his stomach like some of the others that we have tried. It is very convenient to have it delivered here, so I don't have to lug 40 lbs of dog food into my cart , then into my car, then into my house. Great idea Chewy! Now if someone would deliver me perfect food to my door, I wouldn't have to go to town at all!!

  • My Pet Brand Made Easy

    By on

    I am already brand loyal and have been feeding my dogs IAMS for more than 10+ years. Chewy has made it more convenient and delivers it to my door at competitive pricing. Home delivery is very convenient when you can avoid lifting two 30 pound bags in and out of a cart and your car.

  • Iams vs higher priced food

    By on

    I started my puppy on a higher priced food but found he didn't care for it. I have fed Iams in the past so decided to try it now that my boy is an adult. He eats it all and I like that the nuggets are larger. Large dogs need bigger nuggets to chew instead of just swallowing a mouthful and than choke on it. I wish the nuggets were a bit bigger. Very happy with my choice.

  • 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!!!

  • Kibble to big

    By on

    My dog is a red nose pit bull, I thought she would like large kibble but she hates it. The kibble is too large. Now I'm stuck with a 30lbs bag. I actually have to mix peanut butter or cheese in order for her to eat.
