Hill's

Who Makes It

Hill's is made by Hill's Pet Nutrition, a subsidiary of Colgate-Palmolive, and is best known for its Science Diet wellness foods and its Prescription Diet therapeutic foods sold through veterinarians. It also sells the Bioactive Recipe and Healthy Advantage lines. ^{1, 2, 3}

Where It Is Made

Hill's runs its own manufacturing sites in Kansas, including Topeka and Emporia, and opened a plant in Tonganoxie in 2023 to add canned food capacity for Science Diet and Prescription Diet. The company also keeps its main research center, the Pet Nutrition Center, in Topeka. ^{4, 5}

History

The company traces its pet food history to 1939, when veterinarian Dr. Mark Morris Sr. created a kidney diet for a guide dog, and to 1948, when Hill Packing Company of Topeka began producing it as Canine k/d. Science Diet launched in 1968, and Colgate-Palmolive acquired Hill's in 1976. Hill's moved its global and US headquarters from Topeka to Overland Park, Kansas, in late 2023. ^{1, 4}

Worth Knowing

In 2019 Hill's recalled 86 lots of 33 canned dog food varieties across Science Diet and Prescription Diet because of excessive, potentially toxic vitamin D levels. The recall affected only canned dog food, and the FDA terminated it on December 21, 2021. ⁶
