Rated 5 out of 5 by I'm very satisfied My dog food shipment arrived quicker than I expected. The order was correct and the price of the dog food was competitive. If Chewy can keep these prices, I'll continue to shop with them. This was my first order. I usually order online from a large chain pet store. August 22, 2016
Rated 5 out of 5 by best dog food for the best prices I have always wanted to give my dogs the best quality of food but financially it was usually out of my reach. This has allowed me to give them the best at an affordable price. August 21, 2016
Rated 5 out of 5 by Great product at a fair price We have fed out Lab Science Diet dry food from the time she was a pup and she continues to have a shiny coat, clear eyes, white clean teeth and great energy and disposition. What more can you ask! August 26, 2016
Rated 5 out of 5 by The delivery service was great. This was my first order with Chewy. I placed it over the phone and the contact person was very good and very personable - we have a good chat about dogs. I was pleased with the delivery service. While my 2 boxes was quite large - over 35 lbs. the delivery man brought them into my house. I plan on using your service again. August 22, 2016
Rated 5 out of 5 by Great product We have had large breed dogs for 25 years. We have used this product All 25 years and had wonderful success with it. We would highly recommend it, as well as eating at shoulder height. :-) August 14, 2016
Rated 5 out of 5 by Quality product I appreciate how much study went into developing this product and that all ingredients are high quality. I don't feel it's any more expensive than other quality brands. The health of my dog is top priority to me and feeding Science Diet will help him stay that way. July 22, 2016
Rated 5 out of 5 by Fantastic I was pleasantly surprise with my entire transaction with Cheey! August 12, 2016
Rated 5 out of 5 by Great Service! It was really convenient to order our dog food and have it delivered to our home. With an English Mastiff and a St. Bernard, we go through a lot of food! It was great just to have to carry it in the house instead of hauling it from the store! We have been feeding the dogs this food since they were puppies and it has been great! August 2, 2016
