A Guide to Pet Food: Valuable Information for Pet Owners

Veterinarians agree that pets are living longer, healthier lives since the use of commercially prepared pet foods became widespread. Decades of research have gone into the development of pet food to make sure the special nutrition needs of pet dogs and cats are met.

What does “complete and balanced” mean?

Unlike most foods for people, many pet food products are designed to be the sole source of nutrition for a pet dog or cat. Products that are labeled “complete and balanced,” as defined by the Association of American Feed Control Officials (AAFCO), have been tested to make sure they meet the complex nutritional requirements of a healthy dog or cat.

What does it mean on a pet food label that a product has been tested using animal feeding trials?

There are two ways a pet food company can test the nutrition of its products. One method is the use of standardized animal feeding trials, designed by the Association of American Feed Control Officials (AAFCO), to make sure their products meet the complex nutritional requirements of dogs and cats. The animals in these tests are fed the food for six months and are closely monitored to make sure they stay healthy. A product using this test will have language similar to the following on the label – “Animal feeding tests using AAFCO procedures substantiate that Nancy’s Food for Dogs provides complete and balanced nutrition for all life stages.”

What other tests are done to make sure the pet food is good for my dog or cat?

In addition to feeding trials, many companies also use the nutritional profiles developed with the help of feeding trials to make sure their products meet the requirements of dogs and cats at their various stages in life. A product using this test would have language similar to this on the label – “Nancy’s Food for Dogs is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for all life stages.”

Just like food for people, pet foods must be correctly labeled. In addition to a product name and specifying whether it is food for dogs or cats, pet food labels are also required to describe the product, list the ingredients in the food, and list the guaranteed analysis of the product.
All pet foods are required to have a specific brand and will also have the name of the company that made the food and usually a telephone number for consumers to call with questions.

Each ingredient in pet food is there for a reason and to serve a nutritional purpose.

What does the term “guaranteed analysis” mean?

Pet food labeling rules are much more strict than are those for human foods. For instance, a “Blueberry Pancake Mix” for people would probably have only a handful of blueberries in it. A dog food that says “Beef Dog Food” must be 95% beef. A pet food label that says “Chicken Dinner” or “Lamb Formula” only needs to have 25% chicken or lamb, while a “Duck and Potato Dinner” must have 25% of the food made of those two ingredients, with at least 3% being potato. A pet food label that says “…with beef (or “with” any ingredient(s) must have at least 3% beef (or any other named ingredient) in the formula. And finally, if a label says “Chicken flavor”, then there only has to be enough flavor so that pets can pick out that it tastes like chicken to them…people don’t have to be able to tell the difference. It doesn’t matter what the ingredient is, if the label mentions it, the contents must meet these rules.

Pet food is one of the most highly regulated of all food products. Pet food is regulated by the Food and Drug Administration (FDA), the states through their feed laws and the Association of American Feed Control Officials (AAFCO), and the US Department of Agriculture (USDA). This multi-layered regulation and the industry’s commitment to research and education help ensure that pet food products continue to be safe and nutritious for pet dogs and cats.
