  • Excellent food for your puppy with a sensitive stomach

    By on

    This isn't so much a review of the product, but of the wonderful customer service I experienced. My vet had run out of my dogs prescribed dog food, compounded by SANFU with UPS creating a HUGE problem for me as my vet is more than an hours drive away from my home. I had seen the commercials and decided to give Chewy a try. Boy was I ever pleased! A rep from Chewy called my vet for the prescription and the food was delivered within 2 business days! Chewy has become my new go to source for everything my dog. Thank you Chewy for saving me a 3 hour round trip drive and for coming through in a pinch!

  • Pro Plan EN

    The service is great. Recieved my order very fast. My only concern is the food itself. The last bag I received from chewy.com was fine. This bag doesn't seem right. The food is two different colors this time. The dogs will not eat the lighter colored food for some reason, unless that is all that is left in the bowl or floor where they spit it out. I will order another bag when this one runs out and try again. I may also contact Purina and let them know as well as it really isn't a reflection on Chewy.com but on Purina.

  • Great Food. Great Price.

    By on

    When our local vet went out of business we started to look online for a source to get this food for our dog. She's a 3.5lb Morkie who gets an upset stomach on some foods. Our vet recommended this food and we haven't had a single issue since. We save a few dollars buying in on Chewy now and save a trip to the local store/vet to have to pick it up. I will definitely buy this food again on Chewy when the time comes.

  • Purina EN diet

    By on

    My 2 yr old German Shep. has had dietary issues since weaning. EN finally stabilized his issues along with his medication. He readily eats. We tried other brands that advertise pure, this and that, and it would throw him into a week long diarrhea. He's happy, he looks good and I save some on the price. Quick ship!

  • Just started using it so far so good!

    By on

    My 9year old German shepherd is suffering from intestinal distress and when I rescued her she had lost 20lbs. Now she gained back her weight but the previous food was always an issue so I put her on this food and so far so good! And as always chewy.com made it easy to order and I got it in one day. Thanks chewy.

  • Exceptional Food - Works well !

    By on

    I have 2 dogs that have had gastro problems and this food is really great. They both eat well, maintain a healthy weight, and have had no gastric upsets at all. I was having to buy this at my Vet, but thanks to Chewy.com, I get it on a regular order schedule and at a great price.

  • Our dog likes this food

    By on

    We was feeding our little girl the canned food and thought we would switch to the dry food. I thought she would have trouble going from canned food ( which made her poo really stink) to the dry food but she didn’t mind at all. She loves it.

  • Gentle on the stomach

    By on

    This formula is gentle on my dog's stomach. He loved it! Would eat the entire bowl put in front of him. I've been feeding him this for over a month now, and his poop is back to normal and not soft any more. Would highly recommend this.

  • Purina EN dry food

    By on

    My little dog has had some tummy issues, at times we didn't know if she would be OK, but using the Purina EN products has settled her issues and she is back to being a healthy little dog! We use the EN canned moist food, EN dry food, and the Purina Probiotic daily. It keeps her healthy and she loves all of the products!

  • Seems to be a good choice

    By on

    Still on our first bag of this food, but it seems to be helping with the gastro problems my new rescue has been encountering. Recommended by a vet after all medical tests were negative for any problems.
