Royal Canin Renal Special is a veterinary-formulated dry dog food designed for dogs with chronic kidney disease that have developed food aversion or significantly reduced appetite. This formula features an adapted aromatic and flavour profile with enhanced palatability to stimulate food intake in reluctant renal patients. Phosphorus is restricted to 0.3% and protein is controlled at 13% to reduce the metabolic burden on failing kidneys while maintaining essential nutrition. Rice and maize flour provide gentle carbohydrate energy, while fish oil delivers omega-3 fatty acids for renal support. Psyllium husks contribute soluble fibre for digestive comfort. Maintaining adequate caloric intake is one of the biggest challenges in renal disease management, and this formula's 16% fat content ensures concentrated energy is available in every meal. This is a complete and balanced prescription diet for long-term use under veterinary supervision.
