Royal Canin Gastrointestinal Adult dry Dog Food

ROYAL CANIN® Veterinary Health Nutrition Since 1968, Royal Canin has been following the belief that nutrition plays a key role in supporting the health and wellbeing of cats and dogs. This is why we have designed ROYAL CANIN® veterinary diets around proven nutritional science in partnership with pet professionals and experts, delivering nutrition for pets with specific health needs.

If your dog is susceptible to digestive sensitivities, a complete and balanced diet that contains specific nutrients may help to support healthy digestion.

ROYAL CANIN® Gastrointestinal Dry dog food is specially formulated to support the nutritional needs of dogs with digestive sensitivities. This diet is suitable for dogs with:

  • Acute and chronic diarrhoea (including weaning diarrhoea)
  • Gastritis
  • Maldigestion/Malabsorption
  • Dysorexia, re-feeding after surgery
  • Inflammatory Bowel Disease (IBD)
  • Colitis
  • Exocrine Pancreatic Insufficiency (EPI)
  • Acute hepatopathy

Key Benefits:

  • Microbiome Support - Prebiotics help to stimulate the growth and balance of beneficial bacteria in your cat's digestive tract, contributing to a healthy digestive environment.
  • High Energy - The high energy content in ROYAL CANIN® Gastrointestinal to reduce the volume of your dog’s meal and decrease their intestinal load, which makes digestion much easier for your dog whilst also meeting their general nutritional needs.
  • Digestive Support - This highly digestible formula is enriched with a balance of fibres and prebiotics to help support healthy digestion and transit.

As part of the ROYAL CANIN® Veterinary Health Nutrition range, it is important that this product is only given to your pet when recommended by a veterinary professional. Transitioning your pet from one diet to another should be a smooth and gradual process over a 7–10-day period. Please ensure you follow the correct rationing amount, especially when mixed feeding. To cater to each dog’s individual preferences, ROYAL CANIN® Gastrointestinal Low Fat is also available as dry food with crunchy kibble.

Royal Canin Gastrointestinal loaf for dogs
Verified Purchase

By Morag Webster on 12 June 2026

I bought this, on veterinary advice, when my dog was very poorly with an upset stomach following surgery. The food seemed palatable and gentle on her stomach. I was also able to administer her medication hidden in the loaf. I would definitely recommend the Gastrointestinal for helping dogs to recover from stomach problems.

Q & A

Below are some recent questions we've received regarding ROYAL CANIN® Gastrointestinal Adult Dog Food, including answers from our team.

Colitis

Sally Jeans

My lovely 65kg occasionally has bouts of colitis, diarrhoea and bleeding. I have often given him Promax paste. I want a more permanent solution. Shall I give him daily probiotic sachets or change his dog food with Royal canine gastrointestinal biscuit, or will this change of diet cause more problems. Please help

  • VioVet Staff

It is advised to see your vet to rule out more serious causes of this. However you can try a long term probiotic supplement. I recommend ReguTum Gastrointestinal Powder for this kind of issue as it is aimed at long term support.
Changing the diet to an intestinal support diet is also a good idea. However I suggest making one change at a time, so that you know which has helped.

Hydrolyzed Dog food

Stewart Clarke

Please can you advise if this food is Hydrolyzed dog food?

This has been recommended for my German Shepherd who we have recently found has a B12 deficiency. Currently using Virbac Gastro dry food.

Thinking of trying the wet food to increase her desire to eat but need to know if it’s Hydrolyzed or not.

Also, do you stock Hydrolyzed treats that we can use to boost her intake between meals ?

Thanks

Thanks

  • VioVet Staff

This diet does not contain hydrolysed proteins. We do stock a hydrolysed treat product, Hills Hypoallergenic Dog treats. It is important you follow your vet's advice closely on what to feed though, diet can make a signficant difference with intestinal issues like this. If your dog has Vitamin B12 (Cobalamin) deficiency then it is important to supplement additional B12 into the diet. You should approach your vet on guidance of what they suggest using, we stock a wide variety of options on our site including our own brand ReguTum Gastrointestinal Powder.

Prescription

poon

Do I need to have prescription to order Gastro Intestinal Low Fat?

  • VioVet Staff

You do not need a prescription to purchase this diet, however it should only be used alongside veterinary advice.

Age

Rob Dobson

  • VioVet customer since 2017
  • From: Suffolk, United Kingdom

What age is this recommended for please as we are using puppy version for our 12 month old french bulldog

  • VioVet Staff

It is recommended to transfer over from a puppy diet to an adult diet when your dog is fully grown which is usually around the 12 to 18 month mark. At 12 months old your French Bulldog will be almost fully grown and you can now start transferring to the adult version.

Sensitive tummy

sheila

i have two westies who suffer a lot from colitis i.e. wind in tummy eating grass loose stools one is not a good eater very fussy and is the worse of the two which food do you recommend

  • VioVet Staff

This diet is often appropriate for dogs such as yours and may we be suitable, either wet or driy form.. Alternatively Purina EN for dogs can be a good choice.

Difference between gastro and sensitivity

Clare Hancock

I have a very sensitive English pointer who is 6 years old. She has always been very sensitive to food and often has little upset tummy episodes and she is very in tune with my stress and seems to go into sympathy for me! She was extremely poorly 2 years ago with a cat parasite that left her with poor immunity and kidney damage (extent not known) she is fine in herself but lost a bit of weight recently with moving house and the arrival of two babies so I put her on a food to increase her weight but the upset tummy frequency increased and our vet said it's too much protein. She is having a few tins of the royal canine gastro and I just wondered what the difference is between this and the royal canine sensitivity as I need to change her onto one and thought the sensitivity was best but now I'm not sure? She's not a greedy dog and has always had a sensitive tummy. Many thanks

  • VioVet Staff

The Sensitivity Control is based on very different ingredients than the Gastro-intestinal diet. It is however similar in its nutritional properties, should be easily digested and will probably suit your dog well, but you would only know if you try it. If you do this, I would suggest giving a mixture of the diets at first and slowly change the proportions until the switch is complete.
