The gastrointestinal tract includes the esophagus, stomach, small intestine, large intestine, and colon. Therefore, gastrointestinal disease is defined as any abnormality involving one or more of these structures. By feeding your pet a diet that contains precise amounts of key nutrients, you can not only help minimize vomiting, diarrhea,or constipation, you can also help to support and improve the function of the gastrointestinal structures. This gastrointestinal diet is formulated to help maintain the balance of gastrointestinal microflora and intestinal mucosal integrity.

Rated 4.9 out of 5 by 56 reviewers.
Rated 5 out of 5 by My dog loves this product I always ordered this product at my local vet. It just so happened that when I only had two bowls left for my little guy that the vet was sold out. We called every vets office in a 30 mile radius and everyone was completely out. So what does a worried doggy mom do go to the Internet. I can across and they are cheaper than the vets office. So my husband was so worried he's like you better hurry up and order the dog food to make sure it's gets here so our little guy doesn't starve. Well silly me ordered the wrong one. So I called the customer service line and I swear you not it probably rang twice and a representative answered. Tyler was is him. He was so helpful he reordered the right food and even called my vet since this product has to be proscribed. Which made the process go by so much fast. The product was here in two days. They ship very fast. I am very pleased by this company. I will definitely be ordered the rest of my dog from here from now one. September 22, 2016
Rated 5 out of 5 by Working well So far this product has helped with my dog's IBD and loose stool problem. September 24, 2016
Rated 5 out of 5 by Solved digestive issues Our dog was having continual digestive problems. Since our veterinarian started her on this food, she has had a total turn around. She is back to her happy, healthy self with no more problems. September 20, 2016
Rated 5 out of 5 by I Love you Chewy. I love Chewy! The customer service rep was amazing, making my first prescript order easy. I love the 2 day delivery and the prices are fantastic! Thank you Chewy! September 4, 2016
Rated 5 out of 5 by The BEST!!! We were so frustrated with our puppy's stomach issues. It made housebreaking next to impossible. Our vet finally convinced us to give this a try and it was magic! After just one feeding she was in great shape - and has remained so. Thank you Royal Canin. July 16, 2016
Rated 5 out of 5 by An Answered Prayer! My sweet dog is 2 years old. Her entire life, we've been dealing with severe gland issues (which are now removed) and increasingly problematic GI complications (bouts of diarrhea, grumbling tummy, infections setting in for seemingly no reason). Per doctor's orders we switched her from her regular food to Royal Canin GI High Energy. For a while, she did wonderfully well and her system seemed to be balanced. However, the problem still increased in severity. She got to the point where one morsel of food that was not RC GI High Energy would throw her out of whack and an infection would set in. After much prayer, several attempts at switching food, prescribing medications, running tests, etc., her doctor suggested trying Royal Canin GI Fiber Response. For about 5 months now, we have had no problems with digestion and her system is perfectly regulated! I highly recommend this food! December 19, 2015
Rated 5 out of 5 by Great price! Great price and great product! This prescription food has been a Godsend for my 15 year old German Shepard/Lab mix dog with gastrointestinal issues. July 18, 2016
Rated 5 out of 5 by Product was very good The product was very good for my dog and helped his GI problems. June 30, 2016
