Royal Canin Veterinary Diet Urinary S/O review

We don't put a score on this food. It is a veterinary diet, formulated for a diagnosed condition and meant to be fed on a vet's advice. Your vet has seen your dog and we have not, so a number from us could only pull you towards their advice or away from it, and neither of those is ours to do. What follows is what the label declares, what the analysis works out at, and where to buy it, with no judgement attached to any of it.

Royal Canin puts Urinary S/O in its Veterinary Diet range. It is a maize led kibble offered for dogs whose urinary mineral balance a vet is managing.

DryAdultSenior

Royal Canin's Urinary S/O is a maize-led kibble for dogs whose urinary mineral balance a vet is managing, and we do not score it. Minerals sit sixth on the list, because the mineral profile is what the diet controls. Protein is held to 19.6% of dry matter, the intended shape of a urinary diet.

Our view

Likely to suit

  • Dogs whose vet has recommended a urinary diet
  • Owners who want the trace minerals dosed per kilo on the label
  • A dense kibble, printed at 388 kcal per 100g
  • A feeding table that runs from a 2kg dog up to 80kg

Worth watching

  • Every animal entry is a category, so it cannot tell an exclusion plan what it rules out
  • Fish oil and soya oil in a recipe that otherwise reads as bird
  • Portions are the vet's to set; the table on the pack sits below that
