You want what’s best for your furry friend, but how do you make sure the food you’re feeding your pet is good? Does price make a difference? Which ingredients are the healthiest for pets? Which pet foods are the animal equivalents of fast food – tasty, but not a lot of nutritional value? Gaining a better understanding of how to read a pet food label may help in your decision-making process (or just skip to the end for the cheat sheet).
Low Cost vs. Premium Pet Foods
Most grocery store and generic brands are formulated as “variable formula diets.” This means that the ingredients used in the food will vary from batch to batch, depending on market availability and pricing. In contrast, most premium foods sold in feed stores, pet stores and through veterinarians are produced using fixed formulas. Although the cost for a fixed formula food may be more than a variable formula diet, the consistency between batches of food is a distinct advantage to the dog or cat who requires a consistent nutrient profile.
When reviewing the list of ingredients, keep in mind that as with food for humans, they are listed in order of predominance by weight. Also, the ingredient list can give no indicator of the quality of the ingredients used in the food. Ingredients with similar names can vary in digestibility, amino acid content and availability, mineral availability and the amount of indigestible materials they contain. In fact, some premium foods with very high-quality ingredients may have an ingredient list that is almost identical to a generic food that contains poor-quality ingredients with low digestibility and poor nutrient availability. This can be seen in products that claim to be “the same as” another higher-priced product.
Also, in the United States, the name and address of the manufacturer, distributor or dealer of the pet food must be found on the label, usually on the information panel. This information is not required to be complete, and may only include the distributor and city of origin. Most premium foods include the manufacturer’s name, mailing address, phone number, hours of operations and possibly a website address. This makes it much easier to contact the manufacturer with any problems or questions regarding the product.
Common Pet Food Ingredients
Pet food manufacturers in the United States are required to include minimum percentages for crude protein and crude fat, and maximum percentages for crude fiber and moisture. These percentages generally indicate the “worst case” levels for these nutrients in the food and may not accurately reflect the exact or typical amounts included. Also note that these indicate only minimums or maximums found in the foods; actual values may differ dramatically.
|Description||Example||Contribution to diet|
|Meat (muscle)||Skeletal muscle, tongue, diaphragm, heart||Animal fat, protein, energy|
|Meat by-products||Lung, spleen, kidney, brain, blood, bone, intestine||Animal fat, protein, energy|
|Meat meal, meat & bone meal, fish meal, blood meal||Dry rendered product from animal tissue||Animal fat, protein, energy|
|Cereals||Corn, wheat, oats, barley, corn gluten meal||Carbohydrate, protein, fiber, energy|
|Soy flour, soy meal||Vegetable protein source including Textured Vegetable Protein (TVP)||Protein, texture/chunks (usually the meaty chunks in foods)|
|Animal fat, vegetable oil||Tallow, chicken fat, corn oil, soy oil||Fats, fatty acids, essential fatty acids, energy|
|Egg||Egg powder||Protein of high biologic value|
|Milk||Skim milk powder, whey||Milk protein|
|Grain nulls, root crops||Bran, beet pulp||Dietary fiber|
|Humectants||Sugars, salt, glycerol||Increases moisture in food|
|Digest||Hydrolysed liver or intestine||Flavor and palatability enhancer, some protein and fat|
|Preservatives||Sodium benzoate, sodium and potassium sorbate||Retard spoilage from molds and bacteria|
|Flavors||Natural and artificial and “nature identical” flavors, process reacted flavors, key character compounds||Improvement in taste, smell and mouth feel|
|Coloring agents||Natural and artificial colorings||Improvement in owner appeal|
|Aromas||Natural and artificial aromas and tones||Improvement in owner and animal appeal|

What’s More Important Than the Label? (Psst, the Cheat Sheet!)
“It’s almost impossible for the average pet parent to evaluate a pet food based on the label,” states Dr. Susan Wynn, a veterinary nutritionist at BluePearl in Atlanta. “Instead, people should get to know the pet food company and its practices, specifically, if it employs nutritionists.”
In general, a well-established company with veterinary nutritionists on staff and the AAFCO feeding statement on their foods is a trustworthy source of pet food. (AAFCO is the American Association of Feed Control Officials. Having the statement on the label indicates that the food is formulated to meet nutritional levels established by the organization.)
What’s even quicker, and more reliable, than trying to figure out on your own which food to feed your pet? Ask your family veterinarian. Veterinarians look at foods with a critical eye and assess them based on the AAFCO statement, whether the food was tested in a trial, past performance as well as the company’s expertise and track record (i.e. how they handle recalls, if they adjust their formulas based on new discoveries, etc.).
