Pet Food Labels Are Getting Their First Overhaul in 40 Years: What Changes on the Bag

The panel on the back of a bag of dog food has looked much the same for decades: a guaranteed analysis with four minimums and maximums, an ingredient list, and a sentence in small type about nutritional adequacy. That sentence is the most important thing on the package, and almost nothing about the layout helps a shopper find it.

That is what the Association of American Feed Control Officials set out to change. Its membership approved modernized model regulations for pet food and specialty pet food labels on July 31, 2023, published them in the 2024 Official Publication, and recommended a six-year period of enforcement discretion while manufacturers work through packaging. The result arrives slowly and unevenly, because AAFCO is not a regulator and each state decides for itself.

Approved in 2023, arriving bag by bag as states adopt it

AAFCO members approved the modernized model pet food regulations on July 31, 2023 and recommended six years of enforcement discretion after publication in the 2024 Official Publication, so old and new labels will sit side by side on the same shelf for years.

What the modernized label shows

AAFCO describes four changes. A nutrition facts box replaces the old presentation, more closely resembles human food labeling and includes the nutritional adequacy statement. An intended use statement is required on the front display panel so the intended life stage and purpose are visible before you turn the bag over. Handling and storage instructions are standardized, with optional icons. Ingredient naming is clarified, including parentheticals and common names for vitamins, so that a chemical name and its familiar name can appear together.

The Pet Food Institute, the trade group for U.S. pet food makers, adds the detail that matters most for comparison shopping: nutrient quantities are listed in common household measurements, and total carbohydrates and dietary fiber replace the previous crude fiber measurement. A bag whose numbers change under the new format has not necessarily changed its recipe; the measurement behind the number has changed.

The nutritional adequacy statement, the line that says whether a food is complete and balanced and for which life stage, now sits inside the nutrition facts box rather than wherever the designer put it.

The front panel tells you what the food is for; the box on the back tells you what is in it, in units you already use.

Why a trade group, not the FDA, writes this

The FDA sets a short list of federal requirements for pet food labels: proper identification of the product, a net quantity statement, the name and place of business of the manufacturer or distributor, and a list of all ingredients from most to least by weight. The agency also governs ingredients, which must either be generally recognized as safe for the intended use or approved as food additives, with common items such as meat and grains needing no pre-market approval.

Everything else on the label comes from state feed laws, and the FDA notes that many of those state regulations are based on a model provided by AAFCO. That is the mechanism here. AAFCO publishes a model; states adopt it through their own rulemaking; enforcement follows state by state.

AAFCO says each state has its own rulemaking process setting out how the model regulations may be adopted within its borders, and it strongly encourages uniform and timely adoption. It also said its pet food committee would evaluate the enforcement discretion recommendation annually, taking into consideration potential issues or challenges that may arise. In plain terms: expect a long overlap.

The one line that does the most work

The nutritional adequacy statement is the part of the label the modernization is built around. If it includes the phrase complete and balanced, the food is intended to be fed as the animal’s sole diet. To carry that claim, the FDA explains, a dog or cat food must either meet one of the AAFCO nutrient profiles or pass a feeding trial using AAFCO procedures.

Life stage is the second half of the sentence, and it is not a marketing term. AAFCO established two nutrient profiles each for dogs and cats, one for growth and reproduction, which covers growing, pregnant and nursing animals, and one for adult maintenance. A food that carries adult maintenance is not formulated for a puppy, whatever the picture on the front shows.

Anything sold as a topper, mixer or treat is where the statement matters most. The FDA notes that treats, snacks and supplements are typically not intended as a pet’s sole diet, so these products are often not complete and balanced. The modernized front-panel intended use statement is designed to surface that distinction before the purchase rather than after it.

What changes when you compare two bags

Calorie comparisons get easier. Nutrient quantities expressed in household measures, alongside the calorie content that already appears on most bags, make it possible to compare two foods without converting percentages on an as-fed basis into something usable.

Fiber and carbohydrate figures get harder to compare across the transition. A bag printed under the old rules shows crude fiber; a bag printed under the new ones shows dietary fiber and total carbohydrates. Those are different measurements, so a side-by-side comparison of an old bag and a new bag will show a gap that reflects the method rather than the food.

Storage instructions become consistent, which matters more than it sounds. Recalls are announced by lot code and best-by date, both printed on the original packaging, so the standardized storage guidance and the habit of keeping the bag are the two things that let an owner check whether a recall applies to the food in their bin.

• Front panel: species, life stage and purpose in the intended use statement
• Nutrition facts box: calories and nutrients in household measures, with the adequacy statement inside it
• Ingredient list: vitamins allowed to carry common names in parentheses
• Storage and handling: standardized wording, with optional icons

What the new label still will not tell you

It will not tell you the cost per day, which remains the number that decides most switches. Bag size, calorie density and the feeding table interact, and two foods with the same price per pound can differ substantially in cost per feeding.

It will not police the language outside the box either. Words such as premium, holistic and human-grade sit in marketing copy rather than in the regulated panels, and the modernization does not change that. Nor will it arrive everywhere at once: until your state adopts the model and the manufacturer works through existing packaging, the bag in front of you may carry either format, which is the practical reason to learn both.

What to watch next

• Your own state feed control office, for whether the modernized model regulations have been adopted there
• AAFCO’s annual review of its enforcement discretion recommendation, which sets how long the two formats coexist
• Whether the brands you buy switch fiber reporting, since the figure changes without the recipe changing

Questions readers ask

When do the new pet food labels become mandatory?

There is no single national date. AAFCO approved the model regulations on July 31, 2023 and recommended a six-year enforcement discretion period after publication in the 2024 Official Publication, and each state adopts and enforces the model through its own rulemaking.

What is the pet nutrition facts box?

A panel that more closely resembles human food labeling, listing nutrient quantities in common household measurements and including the nutritional adequacy statement. The Pet Food Institute says total carbohydrates and dietary fiber replace the older crude fiber measurement.

Does a lower fiber number mean the recipe changed?

Not necessarily. The modernized label reports dietary fiber and total carbohydrates instead of crude fiber, which are different measurements. A number that moves at the same time as a label redesign may reflect the method rather than the food.

What does complete and balanced actually require?

The FDA says a food carrying that phrase is intended as the sole diet and must either meet one of the AAFCO nutrient profiles or pass a feeding trial using AAFCO procedures. AAFCO maintains two profiles each for dogs and cats: growth and reproduction, and adult maintenance.
