PET FOOD LABEL GUIDE
How to Read Your Pet’s Food Label
A pet food package contains a lot of information. These five checks help you find the parts that matter most for nutrition, calories, and portions.
Tap any numbered part of the package to learn what it means
The package below is a fictional teaching example, not a real product. Older and updated label designs may both appear in stores as states adopt newer AAFCO-based labeling rules, so the same information may be arranged differently.
Real packages may arrange these items differently. Some products still use the familiar label layout, while others may use newer AAFCO-based formats as states adopt them. This illustration groups the key information for learning. See AAFCO’s label guide.
MORE ON THE LABEL
Other label details worth knowing
Pet food labels also list the product name, ingredients, net weight, and the guarantor, the company responsible for the food and its label, which may or may not be the manufacturer. These details help explain what is in the package and who to contact with questions. Tap a card to learn more.
Product name rules Words such as “dinner,” “with,” and “flavor” have specific meanings.
100% or “all”: essentially all of the product must be the named ingredient, except water used for processing and small amounts of permitted preservatives or condiments.
95% rule: a name such as “Beef Dog Food” means the named ingredient or ingredients must make up at least 95% of the product excluding water added for processing, and at least 70% of the total product when that water is included.
25% rule: names using words such as “dinner,” “entrée,” “platter,” or similar terms require the named ingredient or ingredients to make up at least 25% of the product excluding water used for processing and at least 10% of the total product. When more than one ingredient is named, each must make up at least 3% of the total product.
“With” rule: “with chicken,” “with sweet potato,” or similar wording means each named ingredient must make up at least 3% of the product.
Flavor rule: “chicken flavor” does not require a set percentage of chicken. A listed ingredient must provide the named flavor, and the flavor wording must be displayed appropriately.
The wording on the front of the package can therefore describe very different amounts of the ingredient.
Ingredients Ingredients are listed from most to least by weight as they go into the formula.
The ingredient that contributes the greatest weight before processing is listed first, followed by the remaining ingredients in descending order.
That does not mean the first ingredient supplies the most protein, Calories, or nutritional value. Fresh meat, fish, and other high-moisture ingredients can weigh more before cooking because they contain substantial water.
Use the ingredient list to see what is present, but use the calorie statement, nutritional adequacy statement, and nutrient information to understand the food more completely.
Net weight How much food is actually in the package.
Net weight is the weight of the food itself, not the packaging. It is shown in both U.S. customary and metric units, such as 12 lb (5.44 kg), and is often marked “Net Wt.” on the package.
Net weight is not the same as a feeding amount. Two bags of the same weight can provide a very different number of total Calories if the foods have different calorie densities.
For weight-conscious owners, comparing Calories per cup, can, pouch, piece, or gram is more useful than comparing package weight alone.
Guarantor and manufacturer Who is responsible for the label, and who actually made the food.
The guarantor is the company responsible for the product and for the guarantees and claims on its label. Its name and address must appear on the package.
The guarantor is not always the company that made the food. “Manufactured by” means the listed company made it. “Distributed by” or “Manufactured for” means another company may have produced it, often called a co-manufacturer or co-packer. This is common with store brands and smaller brands.
Either way, the guarantor is accountable for what the label says, even when a different company makes the food.
The guarantor is the company to contact when you need information not shown on the package, such as typical nutrient analysis, Calories per gram, quality-control information, or help interpreting a product change.
For a weight-management comparison, asking for the food’s typical nutrient analysis can be more informative than relying only on minimum and maximum values in the Guaranteed Analysis.
The core label pieces stay important even as label formatting changes. Newer AAFCO model regulations mostly change how information is displayed and grouped, not the basic questions owners should ask.
WHY MOISTURE MATTERS
Compare wet and dry food more fairly
Wet food contains much more water than dry food, so the percentages on the package can look very different. This calculator removes the water to give an approximate dry-matter comparison. It also shows grams per 1,000 kcal, which compares nutrients based on the Calories your pet actually eats.
Food A · wet example
Food B · dry example
How are these numbers calculated?
Dry-matter basis: nutrient % ÷ (100 − moisture %) × 100.
Grams per 1,000 kcal: nutrient % × 10,000 ÷ kcal/kg. For example, 26% protein in a food with 3,720 kcal/kg provides about 69.9 g of protein per 1,000 kcal.
Grams per 1,000 kcal is often the most useful comparison for weight management, because a pet eating fewer Calories also eats fewer grams of every nutrient. Your veterinary team can help interpret these numbers for your pet.
SAME VOLUME, DIFFERENT CALORIES
One cup can change a lot between foods
Two dry foods can contain very different calories in the same 1-cup volume. If you change foods but keep filling the same cup, daily calories can change substantially.
Dry Food A: 310 Calories per cup.
Illustrative numbers only. For wet food, use the label’s unit such as per can, pouch, tray, or gram amount. A cup of dry food and a can of wet food are not equivalent portions.
APOP PORTION CHECK
How long should this bag last?
Net weight and calorie content together tell you how many Calories are in the whole bag. If a bag runs out much sooner than expected, portions may be larger than planned, or someone else in the home may also be feeding your pet.
A 12 lb bag at 3,720 kcal/kg holds about 20,250 Calories. At 650 Calories a day, it should last about 31 days.
Your veterinary team can help set your pet’s daily Calorie target. Enter only the Calories that come from this food, not treats or other extras. Illustrative estimate only.
APOP WEIGHT CHECK
Weight-related words on the package do not all mean the same thing
These claims have calorie limits and feeding-direction requirements under the AAFCO model rules.
The label must identify the comparison product and state the percentage reduction in calories.
These are fat-related claims. They do not tell you the food’s total Calories. Check the calorie statement too.
For body-weight management, the practical question is still: how many total Calories does your pet eat in a day, and is that amount appropriate for that individual pet? AAFCO descriptive terms
QUICK ANSWERS
A few more things owners ask about labels
Does the ingredient list tell me which food is best?
Not by itself. Ingredients are listed in descending order by weight, but the list does not tell you nutrient digestibility, bioavailability, quality control, or whether the finished food is appropriate for your individual pet.
Moisture can also affect ingredient order. Fresh meat contains much more water than a dry rendered meal, so position on the ingredient list can be misleading if it is treated as a nutrition ranking. AAFCO ingredient guide
Why can a treat label look different?
Treats and snacks are usually not intended to be a complete and balanced diet, so their labeling can differ from a main food. Start with Calories per treat or piece and count those Calories in the daily total.
For most healthy pets, treats and other extras should make up no more than about 10% of daily Calories unless your veterinary team recommends otherwise.
PET FOOD LABELING MODERNIZATION
Pet food labels are changing, but not all at once
AAFCO approved updated Model Pet Food Regulations in 2023. Each state decides whether and when to adopt those updated requirements. That means owners may see both the familiar label design and newer label designs in stores for several years.
- 2015AAFCO begins the Pet Food Label Modernization project.
- July 2023AAFCO approves the updated Model Pet Food Regulations.
- 2024A transition period begins, and updated labels start appearing on shelves.
- About 2030End of the roughly six-year transition AAFCO recommended. Timing still depends on each state.
What is changing
Calories and nutrients move into a standardized box that more closely resembles human food labels.
Calories are listed per cup, can, pouch, or piece with its gram weight, along with Calories from protein, fat, and carbohydrate.
Guaranteed percentages are shown next to the grams of each nutrient in one serving.
These guarantees replace crude fiber. Both older and newer terms may appear in stores during the transition.
The nutritional adequacy statement appears at the bottom of the Pet Nutrition Facts box on every product.
An intended use statement on the lower third of the front panel identifies the life stage and purpose, including treats, supplements, and mixers.
Rules for parentheses and common names are clarified, so vitamins may appear with familiar names, such as Vitamin B1 (thiamine mononitrate).
Optional handling and storage instructions use a standardized header and may include standard icons.

What is AAFCO, and who actually regulates pet food?
AAFCO is not a regulatory agency. The Association of American Feed Control Officials is a voluntary membership association of government officials who regulate animal feed and pet food. AAFCO develops Model Pet Food Regulations, ingredient definitions, and nutrient profiles, but it does not approve, certify, test, or enforce rules for any product.
Federal: FDA regulates pet food under the Federal Food, Drug, and Cosmetic Act. Pet food must be safe to eat, produced under sanitary conditions, free of harmful substances, and truthfully labeled.
State: Most states have adopted versions of the AAFCO models into their own laws. State feed control officials, often within the state department of agriculture, register products, review labels, and inspect and test pet food sold in that state.
Other organizations: Some claims fall under other agencies, such as USDA for “organic” claims. Groups such as the National Research Council, WSAVA, and veterinary nutrition organizations provide scientific guidance, but they do not regulate pet food. AAFCO · FDA
Do label rules look exactly the same in every state?
Not always. Many states use AAFCO-based model language, but they do not all adopt changes at the same time and some states add their own requirements. For pet owners, that usually means the same key information may appear in a slightly different format depending on where and when a product was labeled.
The safest approach is to focus on the information itself: species and life stage, Calories and the unit beside them, the nutritional adequacy statement, and feeding directions.
