In 1928, Dr. Mark L. Morris Sr. established Raritan Hospital for Animals in Edison, New Jersey. At the time, this was one of only two small animal hospitals in the United States. Dr. Morris believed managing nutrition could have a positive effect on the health of companion animals. He developed the first Prescription Diet® pet food in an attempt to help one of America's first guide dogs who was having kidney health issues. Now decades later, Hill's Pet Nutrition is working to bring pets long, healthy lives. Read the complete story of Hill's Pet Nutrition.
