Hill's Science Diet

Hill's Science Diet is a retail dog food brand from Hill's Pet Nutrition, a subsidiary of Colgate-Palmolive. The Science Diet line launched in 1968 under the guidance of Mark Morris Jr., building on the company's foundation in veterinary clinical nutrition that began in the 1940s.

The range includes over 90 wet and dry food formulas covering different life stages, breed sizes, and dietary needs. Science Diet is positioned in the premium tier, commonly stocked in vet clinics and pet retailers, and formulas are developed by veterinary nutritionists. It sits as the retail counterpart to Hill's veterinary-focused Prescription Diet line.
