Since its creation by Dr. Jean Cathary, a veterinarian, in 1967 in France, Royal Canin has become the world leader in Health Nutrition for dogs and cats. ROYAL CANIN Veterinary Diet® delivers the first real hypoallergenic nutrition innovation in 15 years. With an expanded nutritional lineup backed by the experts, Royal Canin treats the whole animal.

Today, Hill's Pet Nutrition carries on the tradition of caring that began in 1939 with one remarkable veterinarian. The Hill's® pet food lines began in 1939. Dr. Mark L. Morris Sr. believed certain diseases in pets could be managed through carefully formulated nutrition. His ideas were visionary in veterinary medicine, and he soon had the chance to prove his theory.

A young blind man named Morris Frank asked Dr. Morris if anything could be done to save his guide dog, Buddy, who was suffering from kidney failure. The result of Dr. Morris' efforts was the nutritional formulation that became the first product in the Hill's Prescription Diet line of therapeutic pet foods, and the world's first pet food designed to help dogs with kidney disease. Soon after, Hill's Pet Nutrition was founded and the field of clinical nutrition sprang to life. That first therapeutic dog food evolved into Hill's® Prescription Diet® k/d®, which is still sold today.

For over 20 years, Purina Veterinary Diets® have been formulated as nutritional aids in dietary management of dogs and cats with certain health problems. Each diet provides a proper balance of total nutrients while meeting special dietary needs.
