Trying to decipher food labels on human food is hard enough, but understanding pet food label is even more difficult.
The U.S. Food and Drug Administration has set guidelines and standards for pet food and provides a summary of labeling rules. When a product advertises a particular meat in the name of the food, the percentage of meat it must contain is determinate on the wording. If a product name states the meat first, as in "Lamb for Dogs'' or "Tuna Cat Food,'' the FDA rules require that at least 95 percent of the product consist of the named meat, excluding the water that is added for processing. If the pet food name has 2 meats, such as "Beef 'n Chicken Dog Food,'' then two food items together must make up 95 percent of the total, and the first-named product must be the majority. This rule does not apply to grains, so if it is a “Lamb and Rice dog food,” for instance, it still must contain 95% lamb. Read more about Pet Food Labeling
