About Royal Canin Gastrointestinal Health For Dogs

Worried About Your Dog’s Digestion?

Your dog’s gastrointestinal (GI) system helps support the rest of the body by properly digesting food and making sure to extract the nutrients needed for overall health. Your veterinarian is the expert on your dog, so you should always consult with this trusted advisor to find the best gastrointestinal health solutions and management options for your pet.

Know Your Dog’s GI System

  1. Stomach: the first part of the GI tract, where inflamation may lead to vomitting.
  2. Small Intestine and Pancreas: where the small intestine is responsible for absorption of nutrients within the diet and the pancreas aids in digestion; inflamation of the pancreas may be cause by a high fat diet or treats.
  3. Large Colon (Tranverse): which is responsible for forming stool.
  4. Large Colon (Descending): which is responsible for forming stool; any alteration to this process may lead to constipation or diarrhea.
  5. Rectum: where stool leaves the body

How Nutrition Can Help

Talk to your vet about your concerns for your pet's GI tract health. Your veterinarian may recommend a Royal Canin GI formula that is:

Easily digestible to help reduce the load on the gastrointestinal tract

Formulated with omega-3 fatty acids, EPA, and DHA to aid digestive health and antioxidants to support a healthy immune system

Highly palatable to encourage eating, even when appetite is decreased due to gastrointestinal upset

Balanced for good digestion, with a blend of fibers and prebiotics to support digestive health

Find The Perfect Balance

With a dry and wet feeding routine, dry food supports positive oral health while wet food supports healthy hydration.


Keep your pet's feeding on schedule.  Set your order for Autoship to make sure you always have their veterinarian-recommended nutrition on hand.

How big are the pieces of kibble? I have a small breed senior dog 8 pounds & wondering about the kibble size & if it is OK for smaller dogs. Thanks!!
Answer by ChewyFeb 15, 2018
The kibble can vary in size but is approximately half of an inch.

Is high fiber the same as the fiber response? My dog has a very sensitive GI tract and she needs what she has been eating which is the fiber response.
Answer by ChewyDec 13, 2020
Due to your individual pets specific health concern, we recommend consulting your Veterinarian to see what would be the safest fit for your pets current treatment plan.

Excellent food

My geriatric dog is on another Royal Canin low fat moist food due to pancreatitis. On that food she was having issues with her stool being too soft. My vet added this high fiber food, which apparently only comes in kibble. I give this to my dog as a mid-day meal and the moist for breakfast and dinner. She loves the taste and it has done the job in the potty department! She does drink much more water with it, so ensure your dogs water bowl is fresh each day and they are able to relieve themselves more than usual. Royal Canin continues to be the industry leader in specialized RX diets! We are so thankful for them. :-)

Great Food for a dog that needed help

My dog had been sick and my vet recommended this food. His shipment was delayed and I was so happy Chewy sold it and I got it when I needed it. MY dog loves this food, and it has helped with his digestion issues. I highly recommend this food, if your dog has stomach issues

Best food for my dog

My dog has a sensitive stomach and the doctor had prescribed this food her almost 2 years ago and we haven't changed since. Chewy offers the larger sized bag and at a slight discount per pound than the vet clinic. Ordering with chewy rx is super easy and typically gets approved within the next 24 hours.

Royal Canin Presription

Amazing customer service, taking care of the Vet contact thru delivery. Did I mention saving $12 per bag which is important since the largest bag is only 16 lbs. and two 25 lb dogs eating this.

Normal poops finally. FINALLY!!

It is more expensive than my own human food but after all the GI workups on my recently adopted pitbull mix over her first 5 months; regular labwork, expensive labwork, fecal tests, dewormers, probiotics, trying adding metamucil, psyllium husk powder,hippy all bran cereal, pumpkin- you NAME it... This food works. I tried Hills brand fiber Rx diet and Purina Rx EN fiber food when I couldn't get this brand. but neither are as good as this Royal Canin fiber diet. I have tried to mix it with regular high quality food but no dice. Poor Echo paid the price. Seeing her struggle to poop, having poopy accidents (that looked like a dropped pumpkin pie) , and the sheer frustration with wanting to find something that worked her. Do I wish it was not this friggin expensive? Yeah. But it works. And it doesn't cause my dogs digestive tract to cause a landslide everyday. I just resigned myself to my million dollar pup! Lucky duck

My 5 month old pup likes it.

Well the good news is my pup, she likes to eat anything, but my other dog is also liking it. They are not loving it though (hense the missing star).

Good product

One of my dogs has been on this prescription food for several years. She does very well on it. However, in the last year it has been difficult to find this food. I was pleased that Chewy carried it and at a better price! Very glad to have it on auto ship too.

Never again

My 2 year old Lab mix has had anal gland issues since she was 6 months old. We just moved, and she got pretty constipated and picky about drinking water. I chatted with a vet on Chewy, who recommended this brand dog food, and I took it at face value - should’ve done research on the food, but I’m so desperate to help my pup. Started giving it to her (slowly, mixing her regular food with it), and she went 3 days with only pooping the amount of what equaled one normal size bowel movement. Read the ingredients on it… name something in the first 10 ingredients that’s good?! I’ll wait. These dog food companies are sickening with what they put in it. So, there’s $100 out the window. More fiber? I’ll stick to pumpkin purée and water in her meals with her normal food that contains ingredients I can pronounce. Prescription dog food is a joke.
