Hill's Prescription Diet k/d Kidney Care is a dry dog food for dogs with chronic kidney disease. Clinically tested to improve quality of life and slow disease progression, it's the most widely prescribed renal diet for ageing dogs whose kidney function has begun to decline.

Reduced phosphorus protects remaining kidney function — high phosphorus is one of the most damaging factors in advancing renal disease — while controlled high-quality protein keeps muscle mass without overloading the kidneys with waste products. Added omega-3 fatty acids support kidney blood flow, B-vitamins replace those lost through increased urination, and Hill's Enhanced Appetite Trigger technology improves intake in dogs whose appetite has dropped.

Vets prescribe k/d at the first sign of kidney disease because early dietary intervention slows decline more than any other tool. Owners stick with it because dogs feel better, eat better and often gain years of comfortable life on the diet.
