Is Hill's Science diet AAFCO?

Yes, Hill’s Science Diet dog and cat foods are formulated to meet AAFCO nutritional requirements for specific life stages, ensuring complete and balanced nutrition.

Is Hill's Science Diet AAFCO Approved?

Hill's Science Diet is one of the most recognizable names in pet nutrition, often recommended by veterinarians and pet professionals. A common question among discerning pet owners is: Does Hill’s Science Diet meet AAFCO standards? The answer is yes—but understanding what that means involves looking at how pet food is regulated in the United States and what role The Association of American Feed Control Officials (AAFCO) plays.

What Is AAFCO?

AAFCO is a nonprofit, voluntary membership association composed of local, state, and federal officials who are responsible for regulating the sale and distribution of animal feeds, including pet foods. While AAFCO itself does not directly test, certify, or regulate pet foods, it develops the model language and nutritional standards that most U.S. states base their pet food regulations on. These standards ensure pets receive complete and balanced nutrition according to scientific research.

How Do AAFCO Standards Work?

AAFCO establishes:
  • Nutrient Profiles for dogs and cats at various life stages (growth, maintenance, reproduction)
  • Ingredient definitions and labeling requirements
  • Protocols for feeding trials
Pet food companies must meet these guidelines to make claims like “complete and balanced” nutrition on packaging. There are two primary pathways:
  1. Laboratory analysis: The food’s nutrient content is tested to confirm it meets the AAFCO nutrient profiles for a specific life stage.
  2. Feeding trials: The company conducts a feeding trial based on AAFCO protocols that shows the food supports animals’ health in that life stage.

Hill’s Science Diet and AAFCO

Hill’s Science Diet is formulated by a team of veterinarians, nutritionists, and food scientists. The brand emphasizes science-based nutrition and adheres to AAFCO guidelines by either:
  • Confirming nutrient levels through laboratory analysis, or
  • Undertaking AAFCO-standard feeding trials
This information is clearly indicated on product labels under the Nutritional Adequacy Statement. You will typically find one of the following:
  • “This food is formulated to meet the nutritional levels established by the AAFCO Dog (or Cat) Food Nutrient Profiles for [life stage].”
  • “Animal feeding tests using AAFCO procedures substantiate that [name of product] provides complete and balanced nutrition for [life stage].”

Why AAFCO Matters for Pet Owners

Choosing pet food that meets AAFCO requirements is an essential step in ensuring your pet receives all the nutrients they need for optimal health. Products that adhere to AAFCO guidelines have:
  • Appropriate nutrient levels for your pet’s age and life stage
  • Safety and ingredient integrity according to model definitions
  • Confidence that the food is not just palatable but functionally nutritious

Limitations of AAFCO Standards

While useful, AAFCO requirements aren’t flawless. For example:
  • AAFCO does not test or certify foods itself
  • Feeding trials are usually short-term and may not detect long-term deficiencies
  • The profiles do not measure ingredient quality or bioavailability
Still, most veterinary professionals agree that AAFCO standards are the best available framework for formulating pet diets based on current nutritional science.

How to Verify AAFCO Compliance on Label

To ensure the food you’re serving meets AAFCO guidelines:
  • Read the Nutritional Adequacy Statement on the label
  • Look for phrases like “complete and balanced based on AAFCO profiles” or “feeding trials substantiate”, as applicable
  • Check that the product is suitable for your pet’s specific life stage

Conclusion

Hill’s Science Diet does comply with AAFCO nutritional requirements, offering pet owners assurance that the food is created to meet rigorous quality and nutritional standards. While no organization is perfect, AAFCO standards are among the most reliable tools available to guide pet food formulation. By choosing a product like Hill’s Science Diet and checking for AAFCO compliance on the label, pet owners can feel more confident in providing complete and balanced nutrition tailored to their pet’s needs.
