Understanding the Ownership of Hill’s Science Diet
Hill’s Science Diet is a well-known brand in the pet food industry, recognized for its science-based nutrition for dogs and cats. The question of who owns Hill’s Science Diet is important for consumers seeking transparency and insight into the origins, corporate structure, and business practices behind the brand. This article provides an in-depth look at the ownership of Hill’s Science Diet, its historical evolution, and how consumers can find authoritative information about the company and its products.
Corporate Ownership: Hill’s Science Diet and Colgate-Palmolive
The Hill’s Science Diet brand is produced and marketed by Hill’s Pet Nutrition, Inc. , which is a subsidiary of the Colgate-Palmolive Company. Colgate-Palmolive is a global consumer products conglomerate, best known for its oral care, personal care, and household cleaning products, but it also operates a significant pet nutrition division. Hill’s Pet Nutrition was acquired by Colgate-Palmolive in 1976. Under this ownership, the company has benefited from expanded distribution networks, increased research investment, and enhanced marketing resources. [3] [1] [4] [5]
The History and Evolution of Hill’s Science Diet
Hill’s Science Diet has its roots in the 1930s when Dr. Mark Morris Sr., a pioneering veterinarian, developed a special diet for a guide dog named Buddy who had kidney disease. This work, in partnership with the Hill Packing Company in Topeka, Kansas, eventually led to the creation of the Hill’s Science Diet line in 1968. The company continued to innovate with life-stage and condition-specific pet food formulas, building a reputation for science-backed nutrition. [5]
Over the decades, Hill’s Science Diet expanded its product offerings to address various health needs, including urinary tract health for cats and specialized diets for dogs. Despite shifts in consumer preferences toward “natural” pet foods, Hill’s has remained a prominent player by focusing on evidence-based formulations and collaborating with veterinarians and animal nutritionists. [1]
Colgate-Palmolive’s Role in Hill’s Pet Nutrition
Since acquiring Hill’s in 1976, Colgate-Palmolive has played a pivotal role in the brand’s global expansion and innovation. Notable developments include:
- Major investments in research and manufacturing, including new production facilities in the United States and Europe.
- Acquisitions of other pet food companies, such as Prime100, which brought fresh, veterinarian-endorsed dog food into the Hill’s portfolio. [2]
- Growth in global distribution and increased focus on science-based pet nutrition.
Colgate-Palmolive’s stewardship has enabled Hill’s Science Diet to remain competitive in an industry dominated by a few large corporations, including Mars Petcare, Nestlé Purina, and J.M. Smucker. [1]
Recent Developments and Strategic Moves
In recent years, Hill’s Pet Nutrition has continued to evolve. For example, in 2022, Hill’s acquired additional manufacturing facilities in the U.S. and Europe, further expanding its production capabilities. In 2023, the company relocated its global and U.S. headquarters to Overland Park, Kansas, and opened a new manufacturing plant in Tonganoxie, Kansas, to support its growing Science Diet and Prescription Diet brands. [3]
Additionally, Colgate-Palmolive’s acquisition of Care TopCo Pty Ltd, the parent company of Prime100, is expected to further strengthen Hill’s position in the premium, science-based pet food market, particularly in the fresh pet food segment. [2]
Market Position and Competitive Landscape
Hill’s Pet Nutrition is one of the leading pet food brands in North America, accounting for approximately 5.3% of the market with sales exceeding $2.3 billion in 2018. It competes with other major players such as Mars Petcare (makers of Pedigree and Royal Canin), Nestlé Purina, and J.M. Smucker. [1]
The company’s science-driven approach and partnerships with veterinarians have helped it maintain a reputation for quality and reliability, even as consumer tastes shift.
