Hill's Science Diet is a premium veterinary-recommended pet food brand produced by Hill's Pet Nutrition, a subsidiary of Colgate-Palmolive. The brand traces its origins to 1939 when Dr. Mark Morris Sr., a veterinarian, created a special food to help a guide dog named Buddy who suffered from kidney failure. This collaboration between a veterinarian and a pet food maker laid the foundation for clinical nutrition in pet care. Hill's Pet Nutrition produces two main product lines: Science Diet, sold through pet specialty and retail channels, and Prescription Diet, the world's leading therapeutic pet food brand sold exclusively through veterinary clinics. Science Diet products are formulated for everyday nutrition across all life stages, sizes, and specific needs such as weight management, sensitive stomachs, and joint health. The Prescription Diet line offers clinically proven therapeutic nutrition for managing serious health conditions including kidney disease, diabetes, food allergies, and urinary tract issues. Hill's employs over 220 veterinarians, nutritionists, and food scientists and invests significantly in clinical research. The brand's products are backed by decades of scientific research and are recommended by veterinarians more than any other pet food brand. Hill's products are available in over 80 countries and maintain a reputation for stringent quality control and evidence-based formulations.
