How to Read a Pet Food Label (FDA + AAFCO Rules)
The words in a pet food name follow set percentage rules. This guide decodes them, and the rest of the label, using FDA and AAFCO guidance.

The most useful words on a bag of pet food are in the name. “Beef Dog Food,” “Beef Dinner for Dogs” and “Dog Food with Beef” sound alike, but under AAFCO rules they require at least 95%, 25% and 3% beef. Once you know those cutoffs, the rest of the label falls into place.
The product name rules
| Name on the bag | Rule | Named ingredient must be |
|---|---|---|
| “All-beef jerky treats” | 100% | All of the product, apart from processing water and trace additives |
| “Beef Dog Food” | 95% | At least 95% without added water, 70% with it |
| “Beef Dinner,” “Entree,” “Platter,” “Formula” | 25% | At least 25% without added water, 10% with it |
| “Dog Food with Beef” | 3% (“with”) | At least 3% |
| “Beef Flavor Dog Food” | Flavor | Enough to give the flavor; no minimum |
When a name lists two ingredients, the first must be the larger one, and AAFCO says neither can be under 3% of the product. The FDA notes that the 95% rule counts only meat, poultry or fish, so “Lamb and Rice Dog Food” under that rule would need 95% lamb.
A “formula” or “dinner” product can hold more of another protein than the one in its name. The FDA gives the example of a chicken formula cat food that contains more fish than chicken. Read the ingredient list if your pet avoids an ingredient.
Guaranteed analysis
AAFCO requires four guarantees:
- minimum crude protein
- minimum crude fat
- maximum crude fiber
- maximum moisture
AAFCO explains that “crude” names the lab method used to measure protein, fat and fiber.
Ingredient list
The FDA requires ingredients listed by weight, heaviest first. AAFCO adds that each must appear by its official name, in the same type size, so no ingredient gets extra emphasis. The list does not show amounts.
Nutritional adequacy statement
This line says which species and life stage the food suits, such as adult maintenance or growth. AAFCO says most foods should carry one, while treats, snacks and supplements are exempt. Foods that claim to be complete and balanced must also print feeding directions.
Other label rules worth knowing
- The species must appear on the front panel. A picture of a dog or cat is not enough.
- “Proven” needs scientific or empirical evidence behind it.
- “New” or “improved” can stay on a label for six months of production.
- The label must name the manufacturer or distributor and its address.

Frequently asked questions
What does "Beef Dog Food" have to contain?
Under the AAFCO 95% rule, the named ingredient must make up at least 95% of the product not counting added water, and at least 70% counting it.
What is the difference between "Chicken Dinner" and "with Chicken"?
A name with a word like dinner, entree, platter or formula falls under the 25% rule: at least 25% of the product without added water, and 10% with it. "With chicken" only requires 3% chicken.
What does "chicken flavor" mean?
Under the flavor rule, the food needs only an ingredient that provides chicken flavor, such as chicken fat, and the word "flavor" must be printed as large as "chicken."
Do treats need a nutritional adequacy statement?
No. AAFCO says snacks, treats and supplements are exempt. Most complete foods should state which species and life stage they suit.
