    I didn't want to deal with changing from the previous mail order pet supply company so I tried to order my dog's food through her new animal hospital, but in error, they never ordered it. I asked for a prescription and was pleasantly surprised at the ease and speed in ordering and delivering Chloe's allergy food. Thank you.

  • Best Food for my Pitbull

    By on

    Tried many different foods including other ID's. My dog not only has digestive problems, but also skin issues. She had a rash on her face, biting, and licking her feet from the time I rescued her besides vomiting and diarrhea. I saw this food and read the specks, thought I would try it. For the last 6 months rash is completely gone, and stools are the best I ever seen, and no more vomiting. I would very highly recommend this food. Chewy is the Best as well. When I am almost out of food, They rush it too me besides their customer service is impeccable.

  • Great products and prices

    By on

    Wonderful resource! Great Prices! Fabulously convenient! My doggy has sever skin allergies and we can only have her eat certain food and treats! Most places don't even carry Kora friendly food and it has to be special ordered. Thrilled that we can order this regularly now and from the convenience of my home. No having to settle for super expensive products just because they are available. Great site!

  • Easy and Fast

    By on

    I have been giving my dog this food for a few years now and I'm saving nearly $15 a bag by ordering it through chewy.com instead of picking it up at my vet's office. Fantastic!

  • So easy to get now!

    By on

    Our dog has food allergies like you wouldn't believe. Not only does she need prescription diet dog food, it must be duck and potato. In the past we have often been caught out by not ordering soon enough to get the new before the old is all gone. Chewy has solved that.
