How to Read a Pet Food Label
Ensuring good nutrition for your pet means understanding what he is eating.
Every time you visit your local pet store to restock your cat’s or dog’s food supply, it seems that a dozen new products have hit the shelves — all of which claim to be the best, most nutritious and healthi­est formula to ever exist. How do you know whether you’re feeding your pet the equivalent of cheese fries for breakfast or kibble that provides the nutritional value he needs to live a long, healthy life?
By working with your veterinarian and learning about some of the key phrases used on pet food packaging, it is possible to find a diet that meets the nutritional needs of your furry family member. Use this handout as a guide to choose a food your pet will love and you can feel good about.
A pet food product’s name (such as Adult Roasted Chicken, Rice & Vegetable Flavor Dry Dog Food), not to be confused with its brand name (Pedigree), provides initial insight into its quality. Pet food companies market their products with enticing terms such as “dinner” and “flavor,” but a savvy pet owner can learn how to spot the phrases that matter most.
The term “chicken” used alone in a product’s name means that chicken makes up at least 95 percent of the total weight of the product, not count­ing the water used for processing. Counting the added water, chicken must comprise 70 percent of the product. However, when “chicken” is accompanied by “dinner,” “entrée” or “platter,” only 10 percent of the entire product needs to be chicken. A product whose name includes “with chicken” is required to have only 3 percent percent chicken, and “chicken flavor” can be used on labels where very little chicken is used and only then to add flavor. For example, a product called “tuna cat food” must contain at least 70 percent tuna, but a can of “tuna dinner” is only required to contain 10 percent tuna.
The list on a pet food label does not indicate the quality of each ingredi­ent, but learning how to read the list can help you make sure your pet is receiving the proper nutrients. Pet food ingredients must be listed in descending weight order, but there are some loopholes. For instance, items that contain large amounts of moisture, such as beef, poultry or fish, are likely to be listed first. Water content comes into play specifically when looking at dry foods. In these products, ingredients farther down the list may offer more protein but may weigh less because the moisture has been removed.
Another important word on the ingredient list is “by-product.” Pet food ingredients labeled as such are not as harmful as some advertise­ments might portray. By-products can include highly digestible and nutritious organs.
Additionally, some filler items, such as corn, rice, and potatoes, can be listed separately to give the illu­sion that less of the product exists in the total formula. For example, by breaking down corn into individual types — flaked corn, ground corn, screened corn, kibbled corn — each type appears lower on the list.
To meet regulations set by the Association of American Feed Control Officials (AAFCO) — an independent organization that regulates the sale and distribution of pet food — manufacturers must list the minimum amount of protein and fat and the maximum amount of fiber and mois­ture as percentages of the product. This is called the guaranteed analysis.
In cat foods, the maximum per­centage of ash (the mineral com­ponent) is often guaranteed, as are the percentages of taurine and mag­nesium. For dog foods, minimum percentage levels of calcium, phos­phorus, sodium and linoleic acid are found in some products.
Because moisture content can skew the percentages significantly, an accurate comparison of the guar­anteed analysis of two pet foods is possible when they are converted to a moisture-free or dry-matter basis. This would come into play especially when comparing the guaranteed analyses of dry and canned dog food. To distinguish the nutritional value accurately, the moisture content must be taken into consideration.
STATEMENT OF NUTRITIONAL ADEQUACY
Products labeled as “complete and balanced” must contain a nutri­tional adequacy statement indicating that the food contains the minimum amount of all the nutrients the intended animal requires. Determining nutritional sufficiency is done in one of two ways:
1. The product, or the lead member of a family of products, is tested on live animals using AAFCO trial protocols and found to provide adequate nutri­tion. This is the gold standard for determining nutritional adequacy. Products tested in this way include the following label wording: “Animal feeding tests using AAFCO proce­dures substantiate that [product name] provides complete and balanced nutrition.”
2. Rather than testing the food on animals, its ingredients are formu­lated to meet the requirements of a specific nutrient profile established by the AAFCO. With this method, there is no guarantee of nutrient bioavailoability or palatability. These product labels should include the following statement: “[Product name] is formulated to meet the nutritional levels established by the AAFCO [Dog/Cat] Food Nutrient Profiles.”
If a food has not met either of the above standards — and is not clearly identi­fied as a treat, snack or supplement — the label must read: “This product is intended for intermittent or supple­mental feeding only.”
The nutritional adequacy statement also provides details about the life stage(s) for which the product is most suitable. For example, a food labeled for a senior dog must meet the require­ments for adult maintenance and thus should not be fed to a puppy, because it may not have been tested to meet the standards for puppies. Products labeled “for all life stages” meet the more stringent nutritional needs for growth and reproduction.
DEBUNKING PET FOOD MYTHS
Myth: Grains are bad for cats and dogs.
Fact: Animals can have allergies to grains just as they can to chicken or dairy, but grain allergies are not common. Both cats and dogs can metabolize carbohydrates, and “grain free” does not mean carbohydrate free. Dogs that have no known allergy to grains can easily metabolize these carbohydrates and use them as a source of energy.
Myth: Foods labeled “premium” or “gourmet” are better for your pet.
Fact: Products with these labels are not required to contain any different or higher-quality ingredients, nor are they held to any higher nutritional standards than any other complete and balanced product.
Myth: Cat and dog foods are interchangeable.
Fact: Feeding your pet a food not intended for its species could be harmful, because cats and dogs require different nutrients to thrive. Dogs are omnivores and can derive nutrients from grains, fruits and vegetables. Cats, on the other hand, are carnivores and require specific nutrients that are only present in animal sources.
Myth: Products with the ingredient “meat meal” should be avoided.
Fact: The word “meal” simply means that water has been extracted from the product. However, meat meal is not as nutritionally sound as chicken meal, lamb meal, and other hand, are carnivores and require specific nutrients that are only present in animal sources.
