How much do you know about the food you’re buying for your puppy? When shopping for puppy food, pay attention to these three sections of a dog food label.
This section lists all the ingredients that make up the product. The ingredients are listed in descending order according to weight before cooking. In dry food, look for a source of high-quality animal-based protein: chicken or lamb, for example. Dogs thrive on animal proteins.
Manufacturers who use large amounts of vegetable proteins might be saving money by providing basic — but not optimal — nutrition. You should also avoid artificial colors and flavors, which offer no nutritional benefits.
Near the ingredient panel should be a chart of percentages called the 'guaranteed analysis.' These figures reveal the basic nutrient makeup of the dog food's formula and protein content. The minimum percentages of protein and fat and the maximum percentages of fiber and moisture (water) should be listed.
This information must be included on the label by law. A toll-free number or web address for the manufacturer may also be listed. Manufacturers who list a phone number, such as IAMS™, generally have a high-quality product and welcome consumer calls and questions. If you would like information about IAMS products, visit our website or call us toll-free at 800-525-4267.

The Association of American Feed Control Officials (AAFCO) was formed in 1909 to establish a framework for uniform regulation of the feed industry. Although not a government agency, AAFCO operates within the guidelines of federal and state legislation including laws administered by the Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA).
AAFCO establishes standards or models for regulations aimed at ensuring that manufacturers provide clear, accurate, and consistent information about animal feed, including pet food.
Every year AAFCO issues an official publication called the AAFCO Manual. This manual, in addition to listing ingredient definitions and feed terms, addresses labeling issues such as label format, ingredient lists, nutrition claims, and guaranteed analysis.
These model regulations are different than laws. However a large number of state governments have adopted AAFCO pet food model regulations into state law.
The “AAFCO statement of nutritional adequacy or purpose,” also called a “nutrition claim” or “complete and balanced statement,” identifies which life stage and/or lifestyle the product has been approved for. Under AAFCO regulations, this statement must be substantiated by the manufacturer.
AAFCO recognizes three methods for substantiating the claim:
AAFCO has outlined very specific protocols, or guidelines, for conducting feeding tests. The protocols specify test criteria including such things as:
Each life stage has its own protocol. Life stages are the same for both dogs and cats and are defined as:
A pet food with an 'All Life Stages' claim can be used from weaning through adulthood. This claim is considered an unqualified (absolute) representation of nutritional adequacy. If substantiated through feeding trials, the protocol for gestation/lactation and growth must be performed sequentially, using the same group of animals.
AAFCO regulations state that specific wording must be used when a diet is intended for special nutritional or dietary needs that require the involvement of a veterinarian for diagnosis, management, and follow-up.
Understanding the AAFCO statements for nutritional adequacy can help customers choose a high-quality diet that provides complete and balanced nutrition for the appropriate life stage of their dog or cat.
