Product Information

Royal Canin Urinary S/O is formulated for the nutritional management of adult dogs with urinary stones (struvites) and to help prevent their recurrence. This is achieved through the diet's urine acidifying properties and its low magnesium levels.

  • Controlled levels of magnesium, calcium and phosphorus.
  • Promotes a sustainable urine pH level and urinary ion concentration.
  • Enriched with antioxidants and EPA-DHA.

    Expensive but quality

    The food costs a bit but VetsLovePets can get it to me for the cheapest price I can find. My dogs really like it and they and very healthy for seniors. It keeps them out of the vet with urinary issues which used to be a regular occurrence. I think they overall smell better too?

    Libby loves her new food

    Libby (Goldy, almost 12) had Struvite stones removed a couple of months ago. Now she has to be on a strict diet. She loves her bikkies and adapted well to the new "menu" 🐾🐶

Frequently Asked Questions

Dry diets should be stored in their original bags and resealed between feeding. Most small bags include a re-sealable zipper. If the bag does not have this feature, it’s recommended to keep the product in the original bag and store in a dry, airtight plastic or steel container with a lid.

For dry diets, palatability of the kibble remains at its best for one month after the bag is opened, however will be fine for up to two months so long as the bag is stored properly, in a cool, dry, airtight container. 

Introducing your pet onto a new diet should done gradually over 5 - 7 days to avoid the possibility of digestive upset. We suggest:

    Mix 25% of your new diet with 75% of your pet’s previous diet for 2 or 3 days

    Then mix the two diets 50% and 50% for 2 or 3 days

    Then mix 75% of the new diet with 25% of the previous diet for 2 or 3 days

    You can now try feeding with 100% of the new diet.
