Product Description


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 out of 5 by Prescription food that my doggie eats My doggie has digestion problems and this food keeps him regular and he actually eats it! That is not an easy combination. So great! May 2, 2016
Rated 5 out of 5 by Our food sensitive dog loves this food! Our dog has had stomach problems for the last year and has been 100% better since eating Royal Canin Veterinary Diet Gastrointestinal Fiber Response Dry Dog Food. April 22, 2016
Rated 5 out of 5 by Finally success! After several tries at a variety of foods this one has solved Ace's intestinal issues. He is a very happy boy now that his system has become stable and is working normally. He is more regular and is very consistent. We are so happy with the results. I recommend this food to anyone that needs a more regular system. April 3, 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 4 out of 5 by The only that seems to help my greyhound I rescued a greyhound who raced for almost 4 years. When I got him at the beginning of January he had terrible diarrhea and after spending many hundreds of dollars in vet bills this food is the only thing that has helped fairly well. He does not really like the taste so it takes him a long time to eat it but I guess that is better than what we had before. I have to say it is really expensive and I hope to be able to ween him off of it at some point. The customer service and shipping at Chewy have been amazing! February 26, 2016
Rated 5 out of 5 by Get service and great product. This product is great for our 4 yr old Puggle, he gets so excited when it is time to eat. Ordering this product was so easy from your company. March 5, 2016
Rated 5 out of 5 by It's Wonderful! My dog was having constant diarrhea & bleeding. As soon as I started feeding her the Royal Canin Gastrointestinal Fiber Response, she doesn't have diarrhea or bleeding anymore. I'm so glad I got this food & she loves it!! Thank You Royal Canin! March 5, 2016
