Customer Reviews

Rated 4.6 out of 5 by 438 reviewers.
Rated 3 out of 5 by Food didn't settle well with my dog, but Chewy customer service was outstanding! My pup has food allergies and I've been feeding her Royal Canin Hydrolyzed Protein for a while now. And although she does well with that food, she has been itching a lot more recently. My vet suggested I try the Hills Prescription to see if that may work better. Unfortunately…that was not the case. It did not settle well with my her tummy at all and gave her horrible gas. :( I think I'll probably just stick with the Royal Canin for now. Although the product didn't work for me, the customer service was seriously OUTSTANDING! I called to return the item and there was no hassle whatsoever. I was off the phone with the friendly customer service rep in less then 5 minutes and the return was on its way back to my card. I will definitely continue placing my orders through them. Thank you Chewy! June 14, 2016
Rated 5 out of 5 by Quick Delivery, nowhere less expensive, great service. I have to say I was pretty impressed with Chewy. The dog food I bought required a prescription and they were very helpful in ensuring that they shipped as soon as possible - and the time to ship was very short. During this time I worked with Customer Service and they were quick, accommodating, light-hearted and humorous but to the point. The price was $30 lower then anywhere else including Amazon.com. Awesome buying experience..... July 18, 2016
Rated 5 out of 5 by Finally smaller kibble Got a new bag home and noticed improved formula??? Opened it up and finally Hills has made the kibble much smaller!!! The old kind was harder to eat for my Dixie. He seems to love the new formula! Also it doesn't smell nearly as bad as the old formula! July 18, 2016
Rated 5 out of 5 by Good stuff My dog has had stomach issues for 9 months, eating grass every other day, throwing up etc. The Vet recommended trying this food and our dog has improved wonderfully! It's unfortunate it's so expensive b/c I can't really afford to continue feeding it to him. I'm hoping this will at least heal his tummy and then we can go back to regular food. July 15, 2016
