Our verdict

A targeted renal support formula worth discussing with a vet for dogs showing kidney-related appetite loss, though it isn't something to start without a prescription.

Overview

A prescription dry dog food from Royal Canin formulated to support kidney function in adult dogs, sold here in a 6 pound bag of the S (small kibble) Renal Support formula in chicken flavor.

This is a veterinary diet, meaning a veterinarian needs to authorize its use rather than it being a general over-the-counter food. The listed benefit is straightforward: it's built to ease strain on the kidneys and encourage appetite in dogs whose kidney issues have made them reluctant eaters. The formula is free of yam as a listed allergen consideration.

  • Renal Support S formula for adult dogs
  • Chicken flavor, dry kibble form
  • 6 lb / 96 oz bag
  • Prescription required

Who it's for

For dogs already diagnosed with kidney disease or reduced kidney function under a vet's care, not for otherwise healthy dogs looking for a general diet. The all-breed-size recommendation means it applies across dog sizes as long as the underlying kidney condition is present.

Pros and cons

Pros
  • Formulated specifically for kidney support in adult dogs
  • Addresses appetite loss, a common symptom of kidney issues
  • Yam free formula
Cons
  • No listed description or customer review text on this batch
  • Very low recent purchase volume compared to similar-sized listings

Performance notes

The formula targets two things at once, supporting kidney function and stimulating appetite, which matters because dogs with kidney disease often eat less. It's positioned as ongoing dietary management rather than a short-term treatment.
