What's on (and in) a bag of dog food?


What's on (and in) a bag of dog food?

Reading the label on a package of pet food can be an exasperating exercise. Although all labels must include certain elements, finding out where these items appear and what they mean can be difficult. Even skilled nutritional experts like Marion Nestle admit that reading a pet-food label “is no simple task…and hardly anyone can make sense of them.”

Another issue is how these elements are identified. Nutritional standards for the production of pet food are set by the Association of American Feed Control Officials (AAFCO). This nongovernmental group is made up of state and federal representatives as well as people directly involved in the pet-food industry. This means that people who manufacture pet food have a voice in establishing not only pet-food standards but also most of the label requirements and feed-trial protocols. Though the FDA, a federal regulatory agency, sets rules for three of the label items, its oversight of pet-food production is still very limited. As we learned during the 2007 recall, the FDA could not order companies to recall products containing melamine-tainted ingredients. (Sadly, it still doesn’t have recall power.)

AAFCO’s Nutrient Profiles list the minimum amounts (and minimum is the operative word here) of nutrients required by pets. The group recognizes only two canine feeding stages: adult dog maintenance and “growth and reproduction.” So, unless they’re puppies or lactating females, all dogs fall into the “adult maintenance” category regardless of their age, health status or level of physical activity.

There are two components to a pet-food label: marketing and informational. The former is intended to convince you that the product inside the bag or can is the best and tastiest. The content of the latter is, for the most part, dictated by the FDA and AAFCO. These guidelines specify the major components:
• Brand name and product name.

• Who it is intended to feed  (i.e., dog or cat).

• Package weight (net).

• Name and address of the manufacturer.(Phone numbers and/or URLs are not required, but are good things to look for.)

• Statement of Nutritional Adequacy (guidelines that must be adhered to in order to label the food as “complete and balanced”). This is also where you’ll find out how the food meets these standards for nutritional adequacy: by calculation or by live feeding trials.

• Statement of Guaranteed Analysis (listing the minimum percentage of crude protein and crude fat in the food and maximum percentage of fiber and moisture; some companies also specify other nutrients). By the way, “crude” is not a quality statement; it refers to a specific method of measuring the nutrient. Carbohydrates are not included because they are not required in the diet of pets.

• Feeding directions, which are based only on the weight of the animal, so you might run the risk of over-or underfeeding if you follow them. Always monitor your dog’s weight and energy level.

• List of ingredients, identified in the order of “predominance by weight,” or weight before processing. This is important to note when you are comparing products with different moisture contents (see Dry Matter p. 67). Also, as explained by Linda Bren in an FDA Consumer newsletter, “Similar materials listed as separate ingredients may outweigh other ingredients that precede them on the list of ingredients. For example, chicken may be listed as the first ingredient, then wheat flour, ground wheat and wheat middlings. The consumer may believe that chicken is the predominant ingredient, but the three wheat products—when added together—may weigh more than the chicken.”

• The Animal Protection Institute points out that “a good rule of thumb to distinguish the major components of a food is to look for the first named source of fat in the ingredient list. Anything listed before that (and including it) makes up the main portion of the food. Other items, which may add flavor, function as preservatives or [have] dietary benefits (e.g. probiotics, vitamins and minerals),” are present in much smaller amounts.
