Hill's Pet Nutrition (Science Plan, Science Diet, Prescription Diet)

Hill's Pet Nutrition is a leading global brand specializing in science-based pet food. The brand's origin dates back to the late 1930s when Dr. Mark Morris Sr. developed a special clinical diet for a guide dog experiencing kidney failure. This breakthrough led to the formal creation of Hill's Pet Nutrition, which revolutionized the pet healthcare market by introducing clinical nutrition for domestic animals.

Today, the brand operates as a major segment of the Colgate-Palmolive company. While its primary research and production facilities are located in the United States—most notably in Topeka, Kansas—the brand maintains a global manufacturing footprint to distribute its Prescription Diet and Science Plan lines across international markets. Its products are widely recommended by veterinarians because of the intensive biological research and focus on pet gene expression and microbiome health.

Hill's remains a cornerstone of the professional pet food sector, maintaining its reputation through rigorous scientific testing and a deep-rooted history in veterinary medicine. Ownership under the Colgate-Palmolive umbrella has provided the brand with the scale to influence pet health globally while maintaining its focus on specialized ingredient formulations.
