What are AAFCO Dog Food Nutrient Profiles?

AAFCO list image

If you’ve closely studied your dog’s food label, you may have noticed “AAFCO” mentioned somewhere on the bag. What is AAFCO and what does it do, though?

The Association of American Feed Control Officials is a voluntary membership association. It’s a multidisciplinary group comprised of federal and state officials, veterinarians, scientists and more.

They are tasked with identifying safe ingredients, outlining pet food label requirements and building nutrient profiles based on the latest findings in pet nutrition research. States use AAFCO’s guidelines as a baseline when creating their pet food regulations.

Does AAFCO Approve or Regulate Dog Food?

No, AAFCO does not have the authority to inspect, approve or regulate dog food (or any other pet food).

Although members represent state and federal regulatory agencies like the U.S. Food and Drug Administration (FDA), AAFCO itself does not regulate the pet food industry.

The FDA is responsible for regulating pet food within its respective states.

What Does AAFCO Do?

Rather than regulating the pet food industry, AAFCO sets the standards for quality pet nutrition by creating (and revising as needed) nutrient profiles.

A dog food can only claim it is “complete and balanced” if it meets or exceeds AAFCO’s minimum requirements, as outlined in the nutrient profiles.

What are AAFCO’s Dog Food Nutrient Profiles?

The Association of American Feed Control Officials developed nutrient profiles to “establish minimum and some maximum nutrient concentrations for dog and cat foods.”*

Although AAFCO has been around since 1906, these profiles were not created until 1991. (Cat food profiles were created in 1992.) According to the FDA, the nutrient profiles are updated as “new, science-based nutritional information becomes available, most recently in 2016.”

These profiles are updated when new findings from research in pet nutrition becomes available. They provide practical guidance for pet food manufacturers.

There are two dog food nutrient profiles: Adult Maintenance and Growth and Reproduction.

  • Adult Maintenance: Dog foods formulated for adult maintenance have the nutrients adult dogs need. Dogs over the age of one are considered adults, except for some large and giant breeds who do not fully mature until age two.
  • Growth & Reproduction: The Association of American Feed Control Officials recognizes puppies and pregnant or lactating dogs have different nutritional needs from adult dogs. As such, they developed a nutrient profile for this group.

You may see variations of these nutrient profiles on dog food packaging. A food that fits into the Growth and Reproduction nutrient profile may state it’s formulated for puppies or gestational mothers.

Is there an AAFCO Nutrient Profile for All Life Stages?

The only two AAFCO nutrient profiles are Adult Maintenance and Growth and Reproduction. Dog food manufacturers can develop and market a product as suitable for all life stages, though.

Similarly, foods that fit into the Growth and Reproduction nutrient profile may state they are formulated for puppies or gestational mothers.

How are Dog Food Nutrient Profiles Evaluated?

To claim a dog food product meets AAFCO’s nutrient profile standards and is “complete and balanced,” it must first be evaluated. There are two methods to evaluate whether a dog food meets these standards:

  • Nutrient Content Analysis: With this method, a laboratory analysis uses a small sample of the food to verify it meets AAFCO’s standards. If it does, the dog food label will read “[Product Name] is formulated to meet the nutritional levels established by the AAFCO dog food nutrient profiles.”
  • AAFCO-Compliant Feeding Trial: In addition to the laboratory analysis, this method includes feeding trials with real dogs to demonstrate the food’s nutritional values. If this method was used, the label will read “Animal feeding tests using AAFCO procedures substantiate that [Product Name] provides complete and balanced nutrition.”

You can typically find these statements on the dog food package beneath the ingredient list.

Are Dog Food Products that Don’t Meet these Standards Allowed on Shelves?

Yes, dog food products that do not meet AAFCO’s nutrient profile standards are allowed on shelves. In some cases, the label may say, “This product is intended for intermittent or supplemental feeding only.”

This usually applies to treats and supplements, which are formulated to make up a small portion of your dog’s total caloric intake (10 percent or less, daily). It can also apply to some veterinary diets, as these are formulated to address specific nutritional needs.

All of Purina’s dog food products meet or exceed AAFCO’s nutrient profile standards, so you can feel confident knowing your dog is eating a complete and balanced diet. Explore all our dog foods and don’t miss out on other dog nutrition articles.
