Rated 5 out of 5 by Great product, great service! The web site is super easy to navigate. Signed up for auto delivery so I won't have to run out at the last minute. And delivered right to my doorstep. July 26, 2016
Rated 5 out of 5 by Great food for my Shepard My Shepard's are doing really good on this food and their coats are looking really good. They did have problems with dry patches on their skin but since on this food they are doing good. July 16, 2016
Rated 5 out of 5 by Great price and convenience We wanted to switch to Hills Science Diet for our Labrador Retriever. Heard about Chewy.com. so we placed an order for two 35 lb. bags of Science Diet. Received the package in two days. Couldn'the ask for a more convenient shopping experience. The price was better too. July 10, 2016
Rated 5 out of 5 by Easy and Convenient I absolutely love not having to leave the house to purchase my dog food. As seniors, it is much easier! Thank you Chewy! June 25, 2016
Rated 5 out of 5 by Delivery was timely and the product is excellent I am very impressed with CHEWY- I highly recommend the product, service, and cost. June 22, 2016
Rated 5 out of 5 by Very happy with this food Recently switched my dog to this food from Hills Large Breed Lite. The lite was very good also but the adult 6+ is slightly higher in protein and the kibble is bigger. Just thought she could benefit from a little extra protein and she enjoys the bigger kibble as she gets older and enjoys her life as a retired livestock guardian. Very happy with the switch, Hills quality, and the autoship plan. June 1, 2016
Rated 5 out of 5 by terrific for my old dog My German Shepherd is 13 and sometimes a finicky eater. My vet recommended this for him and he loves it. She said "there are alot of products now on the market, but I'm old school, I recommend Science Diet." I'm glad she did. He looks terrific and seems to feel great as well. June 6, 2016
Rated 5 out of 5 by great food for our adult dog Unbelievable service. We received our two bags of dog food in two days. Fritzi was very happy. June 3, 2016
