A commitment to quality
and safety

Product Development

Over 150 veterinarians, food scientists, technicians and Ph.D nutritionists at Hill’s develop Science Plan and Prescription Diet brand pet foods to meet the needs of your pet when it’s well or when it’s sick. Each ingredient is analyzed to ensure its safety when included in the food your pet eats. We analyze our products’ ingredient profile for over 100 nutrients to ensure your pet gets the stringent, precise formulation it needs.



Ingredient Supply


We inspect every ingredient via microbiological, sensory, chemical and foreign matter testing to give you peace of mind when you feed your pet. Only ingredient suppliers whose facilities meet stringent raw material quality standards are approved by Hill’s. Every location for every ingredient supplier is separately qualified to ensure consistency in ingredient quality.



Product Manufacturing


Product quality is continuously monitored and electronically documented through on-line quality checks throughout the manufacturing process. We conduct annual Quality Systems audits for all manufacturing facilities to ensure we meet the high standards your pet deserves.
We demand compliance with Good Manufacturing Practices (GMP) and American Institute of Baking (AIB) standards, so your pet’s food is produced under clean and sanitary conditions.



Finished Product


We conduct final, daily safety checks on every Hill’s Science Plan and Hill’s Prescription Diet pet food product to help ensure the safety of your pet’s food. All Hill’s pet food products are screened for metal detection and foreign material prior to release. All finished products are physically inspected and tested for key nutrients prior to release to help ensure your pet gets a consistent product bag to bag.
