Promotes digestive health and optimal stool quality with highly digestible proteins and prebiotics

Formulated to help manage common gastrointestinal sensitivities

Enriched with a blend of soluble and insoluble fibers for healthy GI transit

Helps manage GI health with omega-3 fatty acids, EPA and DHA

You’ve tried everything to help with your dog's GI issues, whether those are vomiting, diarrhea, or lack of appetite. And while bland homemade diets are often used for digestive upsets, your dog could be missing some key nutrients to help them fully recover. But with the help of your veterinarian and Royal Canin, there’s not just hope—there can be a true difference.

This high fiber dog food is specially formulated with a blend of soluble and insoluble fibers to aid with intestinal movement and support your dog’s GI issues. A combination of highly digestible proteins and prebiotics helps maintain the balance of good bacteria in the gut. A blend of dietary fibers supports healthy digestion for optimal stool quality. Omega-3 fatty acids, EPA and DHA, from fish oil help nourish and soothe the GI tract. And a precise blend of antioxidants supports a healthy immune system. Looking for a way to reward your dog? Royal Canin Gastrointestinal dog treats are just 4.5 calories and are made for your dog’s sensitive stomach.

I bought this product for my dog after a friend recommended it. He is a boerboel/pitbull mix. Since his birth he has had tummy problems. I have tried numerous brands and found that this food helped.
