Rated 4.8 out of 5 by 117 reviewers.
Rated 5 out of 5 by My St loves it... We have a 4 year old St Bernard/Pyranese mix. We started out on a higher priced Petsmart dog food. She was digging up all of our tree roots, and eating them. She was eating the bark off of the trees. We thought, she's bored. We spent all of our time with her, we bought every stimulating toy we could find. After a comment to our vet, just a random comment really.. He figured she had a nutritional imbalance. He recommended we try Iams, for large breeds... Since then, she hasn't touched the trees in any way. She loves this stuff! We won't change food again. Until her needs change anyway! October 26, 2016

Rated 5 out of 5 by Good deal Product was priced well and service was quick. Very satisfied will reorder from chewy.com October 22, 2016
Rated 5 out of 5 by Great Service I have two large dogs. I do not buy very much on line but after a friend said she ordered her pet food via the Internet, I decided to try it. Why had I procrastinated in buying this way? Not having to lug bags of food from town was wonderful, the savings worthwhile and the service excellent. I hope this will continue October 16, 2016
Rated 5 out of 5 by My Dogs Love IAMS My 6 year old and 12 year old Pit Bulls seem to "love" IAMS. They will walk away from other more expensive brands. October 17, 2016
Rated 5 out of 5 by Review on Chewy moreso than the product This was the first time I tried this website and I did so because they sent an appealing coupon that made it worth the try. Now, I am absolutely a believer in this site. Firstly, the price for the product was much better than any local supplier, warehouse club provider, etc. Secondly, with shipping free it made it so nice not to hassle with carrying and loading these large bags. The product shipped immediately and I had it within 2 days. This was a really economic and excellent way to purchase my dog food supply and I will continue to use this site. October 4, 2016
