Navigating the dog food aisle can feel overwhelming. With countless brands and formulations promising optimal health for your furry friend, making the right choice can seem daunting. It’s essential to remember that at a minimum, dog food in the US adheres to labeling standards set by the Food and Drug Administration (FDA). These regulations ensure that pet food labels include crucial information such as the producer’s name and address, and a list of ingredients ordered by weight, similar to human food packaging. Furthermore, many states have adopted labeling guidelines based on the Model Regulations of the Association of American Feed Control Officials (AAFCO), a non-profit organization setting nutritional standards and label regulations for pet food.
Veterinarians consistently emphasize the importance of looking for an AAFCO nutritional guarantee on any dog food label. Most states in the US have incorporated AAFCO’s standards into their regulations through agricultural, health, or feed departments. While the FDA oversees pet food ingredients and label appearance, AAFCO’s guidelines are vital for nutritional adequacy.
Understanding “Complete and Balanced” Dog Food
“For the average dog owner, the primary focus should be ensuring the diet is ‘complete and balanced’,” advises Dr. Jonathan Stockman, a veterinary nutritionist at Long Island University. This is best determined by checking the AAFCO statement on the dog food label. This statement specifies the species (dog), life stage (e.g., puppy, adult, senior), and food type (e.g., maintenance, growth) the food is formulated for. Choosing food appropriate for your dog’s life stage is crucial. For instance, a senior dog fed a high-calorie puppy food might gain excessive weight, whereas puppies require food specifically designed for growth. It’s also critical to remember that dog food is not suitable for cats, as they have distinct nutritional needs.
Verifying Health and Safety Through Feeding Trials
A dog food label should declare whether the food is “formulated to meet nutritional levels established by AAFCO nutrient profiles”. This formulation is typically verified through laboratory analysis. However, the gold standard for ensuring a dog food’s health and safety is through AAFCO feeding trials. These trials demonstrate that the food supports the animal’s health and well-being when actually consumed.
When a food is “formulated to meet nutritional levels,” it means the manufacturer has ensured the ingredient composition aligns with established nutritional requirements. Many such foods, particularly from reputable companies, can be safe and healthy for dogs. However, “ideally, I prefer a diet substantiated by feeding trials,” states Dr. Amy Nichelason, a veterinarian at the University of Wisconsin-Madison. Feeding trials offer a higher level of assurance about the long-term safety and efficacy of the diet and its ingredients.
There’s also a third substantiation method: a label might state that the product is “similar” to a food that has undergone and passed feeding trials. This approach is sometimes used for foods that are only slightly modified (e.g., different flavor) from a tested base formula, as feeding trials are costly.

Understanding Supplemental and Prescription Dog Foods
If a dog food label lacks an AAFCO statement, look for phrases indicating it’s “intended for supplemental feeding only.” These foods are designed as treats, food toppers, or mix-ins, not as a primary food source. While they may have nutritional content, they shouldn’t constitute more than 10% of your dog’s daily diet. A dog’s main nutrition should come from a “complete and balanced” dog food.
Prescription dog foods, available only through a veterinarian, might also lack AAFCO statements. These specialized diets, like vegetarian diets for medical conditions, are formulated for specific health needs and may not be intended as “complete and balanced” for healthy dogs according to AAFCO standards.
Decoding Ingredient Names and Percentages
Don’t be misled by product names like “Dog Food with Chicken” into thinking it’s primarily chicken. AAFCO regulations govern how ingredients can be listed in product names. Ingredients in the title must be listed in order of predominance, mirroring the ingredient list. However, the required percentage of an ingredient to be included in the name varies greatly, from as little as 3% to as much as 95%. Therefore, always checking the ingredient list is crucial.
Even if an ingredient like “deboned chicken” is listed first, it doesn’t guarantee it’s the primary component in the final product weight. As veterinary nutritionist Joe Wakshlag explains, “If I dried it all down… that chicken would not really be the number one ingredient” by weight in the final dry food product. Understanding these nuances helps in making informed decisions about the best dog food for your dog.
