How to Read a Dog Food Label

The short answer: the most important thing on a dog food label is the small-print AAFCO nutritional adequacy statement, which tells you whether the food is complete and balanced and for which life stage. After that, check the calorie content so you can feed the right amount. The ingredient list and the marketing on the front of the bag tell you much less than most people think.

1. The AAFCO statement: start here

AAFCO (the Association of American Feed Control Officials) sets the nutrient standards that US pet foods follow. Every complete diet should carry a statement like one of these:

• "[Food] is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for [life stage]." The recipe was designed and analyzed to meet the standards.
• "Animal feeding tests using AAFCO procedures substantiate that [food] provides complete and balanced nutrition for [life stage]." The food was also fed to dogs in a controlled trial.

Then check the life stage:

• Growth (puppies) or all life stages: suitable for puppies and adults. For puppies expected to weigh 70 pounds or more as adults, look for "including growth of large size dogs." See our large breed puppy guide.
• Adult maintenance: for adult dogs only, not puppies or nursing mothers.
• "For intermittent or supplemental feeding only": not a complete diet. This is common on toppers, treats, and mixers, and those shouldn't be fed as a dog's only food.

If there's no AAFCO statement at all, don't feed it as a complete diet.

2. Calorie content

Every bag or can lists calories, as kcal per kilogram and usually kcal per cup or can. This is the number that matters most for weight control.

Two foods can look similar but differ by 100 calories or more per cup. When you switch foods, recalculate how much to feed instead of using the same scoop.

3. Product names follow rules

The name on the front tells you roughly how much of the named ingredient is in the food:

4. The ingredient list: useful, but often over-read

Ingredients are listed by weight before cooking, including their water. Fresh meat is about 70% water, so "chicken" can top the list while contributing less protein than a dry ingredient like chicken meal listed further down.

A few things worth knowing:

• "Meal" (such as chicken meal) is a concentrated, dried protein source, not a filler.
• By-products can be nutritious organ meats; the term alone doesn't mean low quality.
• Ingredient splitting happens when one ingredient is listed in several forms (peas, pea protein, pea fiber) so each appears lower on the list than their combined total would be.
• Watch for legumes such as peas, lentils, and chickpeas high on the list; see our grain-free and heart disease guide.

5. Guaranteed analysis

The guaranteed analysis lists minimum protein and fat and maximum fiber and moisture. It's a rough guide, not the exact amounts.

To compare a wet food with a dry food, convert to a dry matter basis: divide the nutrient by the non-water portion. For example, a canned food with 10% protein and 78% moisture is 22% dry matter, so its protein on a dry matter basis is 10 ÷ 22, or about 45%. That's more protein than a typical kibble at 26%, even though the label number looks lower.

6. Marketing words

• "Human-grade" is a defined claim: every ingredient and the finished food must meet human food standards. See our fresh food guide.
• "Natural" has a definition (no artificial or synthetic ingredients other than added vitamins and minerals), but says nothing about nutrition.
• "Holistic," "premium," and "ancestral" have no official definition.
• "Grain-free" describes what's not in the food, not whether it's better.

7. Who makes it

Look for the manufacturer's or distributor's name and contact information. Good companies will answer questions such as whether they employ a board-certified veterinary nutritionist, where their food is made, and what quality testing they do.

When to talk to your vet

Bring the bag, or a photo of the label, to your vet visit if your dog has a health condition, is a puppy or senior, or is gaining or losing weight. Your vet can confirm the food fits and help you set a daily calorie target.

Practice on a few labels

These kibbles carry AAFCO complete and balanced statements. Compare their labels using the steps above.
