Overview
Royal Canin Veterinary Diet Canine Urinary SO, model 426025, is a veterinary-exclusive dry dog food in a 25.3 lb bag, formulated with a chicken-based recipe to support urinary tract health and help prevent crystal formation.
As a veterinary diet, it is meant to be used under a vet's direction rather than picked as a general everyday food, and the listing credits its RSS methodology for managing urinary crystal risk. It is labeled for all breed sizes rather than a specific size range.
