A Pet Owner's Guide to FEDIAF Pet Food Labelling in Europe

If you have ever stood in a pet shop aisle squinting at a bag of kibble, trying to work out whether “with chicken” actually means there is much chicken in it at all, you are not alone. Pet food labels can read like a small chemistry textbook — and that is largely because they are written to satisfy a lot of legal requirements. The good news is that once you know what those requirements are, the label becomes a surprisingly powerful tool for choosing the right food for your dog or cat.

In Europe, most of the rules sit in EU legislation, but the day-to-day interpretation is shaped by FEDIAF — the European Pet Food Industry Federation. FEDIAF publishes the Code of Good Labelling Practice for Pet Food and the Nutritional Guidelines for Complete and Complementary Pet Food for Cats and Dogs. Together, these documents are the unofficial rulebook that responsible European brands follow.

This guide walks you through what every European pet food label must tell you, what the marketing language really means, and what is changing in 2026 — from QR codes to sustainability claims.

1. Who is FEDIAF, and why should you care?

FEDIAF represents the pet food industry across the EU and several neighbouring countries. It does not write law itself, but it does two important things. First, it interprets EU regulations — mainly Regulation (EC) No 767/2009 on the marketing and use of feed, and Regulation (EC) No 1831/2003 on additives — and turns them into practical guidance for manufacturers. Second, it sets the nutritional benchmarks that define what “complete” food actually means for cats and dogs.

For you as an owner, that means a label from a FEDIAF-aligned brand should be honest, comparable to others on the shelf, and nutritionally meaningful. It is the closest thing Europe has to a single, trusted standard for pet food information.

2. The mandatory particulars: what every label must show

Under EU feed law and the FEDIAF Code, certain information is non-negotiable. Whether you are looking at a 200 g pouch of cat food or a 15 kg sack of dog kibble, you should always be able to find the following items. They might be split between the front and back of the pack, but they must all be there.

2.1 Product name and species

The name has to make clear what the product is and who it is for. “Complete dry food for adult dogs” or “Complementary wet food for kittens” are typical examples. The species (dog, cat, etc.) and life stage (puppy/kitten, adult, senior) should be unambiguous — a food sold for cats cannot simply be labeled “pet food."

2.2 “Complete” vs “complementary”

This single word changes how you should feed the product:

• Complete — designed to be the sole source of nutrition. Fed in the right quantity, it provides everything your pet needs.

• Complementary — designed to be fed alongside other food. Treats, toppers, broths, and many wet foods fall into this category. They are not nutritionally balanced on their own.

If a product is complementary, the label must say so clearly, and it should not be the only thing in your pet's bowl day after day.

2.3 Composition (the ingredient list)

The composition lists every ingredient in descending order of weight at the time of mixing. There are two acceptable styles:

• Open declaration — each ingredient named individually (e.g., “chicken (28%), rice (22%), maize, chicken fat, beet pulp…”).

• Category declaration — ingredients grouped under EU-defined categories such as “meat and animal derivatives”, “cereals” or “vegetable protein extracts”.

Neither style is inherently “better”, but open declarations give you more visibility into exactly what your pet is eating. If a specific ingredient is highlighted on the front of the pack (“with salmon”), the percentage of that ingredient must usually appear in the composition — a rule known as QUID (quantitative ingredient declaration).

2.4 Analytical constituents

This is the small table that shows the nutrient profile of the food. For dogs and cats, the following must be declared as a percentage:

Nutrient	What it tells you
Crude protein	Total protein content is important for muscle, skin, and immune function.
Crude fat / fat content	Energy density and source of essential fatty acids.
Crude fibre	Indigestible plant material that supports gut transit.
Crude ash (inorganic matter)	Mineral content—high ash is not necessarily bad, but very low ash can indicate a low-mineral recipe.
Moisture	Required if above 14% — critical for comparing dry and wet foods on a like-for-like basis.

Some products list more (calcium, phosphorus, omega-3, taurine, etc.) when those nutrients are relevant to a claim or to a particular life stage.

2.5 Additives

Additives are split into three groups on a European label:

• Nutritional additives—vitamins, trace elements (zinc, copper, selenium…), and amino acids. These must be declared with their amount per kilogram.

• Sensory additives—colorants and flavorings. They may be grouped as "colorants" or "flavorings" rather than named individually.

• Technological additives — antioxidants and preservatives. If only EU-permitted natural antioxidants such as tocopherols (vitamin E) are used, the source is often highlighted on pack.

The presence of additives is not a red flag in itself—vitamins and minerals are essential to making a food nutritionally complete. What matters is transparency about what is in there.

2.6 Net weight, batch and best-before

Three small but important details:

• Net quantity in grams or kilograms (or milliliters for liquids).

• Batch / lot number — essential if a product ever needs to be recalled or traced.

• Best-before date — “Best before end” for shelf-stable products, often shown alongside storage advice once the bag is opened (typical guidance: use dry food within 4–6 weeks of opening, store in a cool, dry place).

2.7 Feeding instructions

FEDIAF requires clear daily feeding guidance — usually a table of grams per day based on the pet's adult bodyweight and, ideally, activity level. These figures are starting points, not gospel: they assume an “average” pet at a healthy weight. Always adjust based on body condition score and consult your vet for working dogs, pregnant or lactating animals, or pets with medical conditions.

2.8 Manufacturer details and approval number

Every label must show the name and address of the business responsible for the product within the EU, plus an approval or registration number issued by the competent authority. This is your guarantee that the facility is known to regulators and subject to inspection.

3. The science behind “complete”: FEDIAF nutritional guidelines

When a label says “complete and balanced”, the brand is committing to a specific scientific standard. In Europe, that standard is the FEDIAF Nutritional Guidelines. They define minimum (and sometimes maximum) levels for over 40 nutrients across life stages: puppy/kitten, adult maintenance, gestation/lactation, and senior.

In practice, this means a complete food for an adult cat must deliver enough taurine, arachidonic acid, vitamin A, and other species-specific essentials — nutrients that dogs can synthesize but cats cannot. A complete puppy food must support skeletal growth without overshooting on calcium. These are not arbitrary numbers; they are reviewed regularly against current veterinary nutrition science.

FEDIAF guidelines are not legally binding in the same way EU regulations are, but most reputable European brands formulate to meet or exceed them, and many state this explicitly on pack or on their website.

4. Reading between the marketing lines

This section is the section most owners actually want. Once you know how the rules work, the front of the pack becomes much easier to interpret.

4.1 The “flavour / with / rich in” ladder

There is a strict hierarchy for how much of an ingredient must be in the food before you can talk about it on the front of the pack:

Wording	What it means
“Chicken flavour”	Less than 4% of the named ingredient. Aroma rather than substance.
“With chicken”	At least 4% of the named ingredient.
“Rich in chicken”	At least 14% of the named ingredient.
“Chicken” (e.g. “Chicken dinner”)	At least 26% of the named ingredient must be present.
“All chicken” / “100% chicken”	100% of the named ingredient — only realistic for single-ingredient treats.

Knowing this latter is the single most useful trick for shopping European pet food. “Rich in salmon” and “salmon flavor" are very different products.

4.2 "Natural," "grain-free," “hypoallergenic”

"Natural" has a specific FEDIAF definition: ingredients must come only from plant, animal, micro-organism, or mineral sources and may only be subjected to physical processing (drying, freezing, milling, etc.). Synthetic vitamins and minerals can still be added to make the food complete — in which case the label often says “natural with added vitamins and minerals”.

"Grain-free" simply means the recipe contains no cereals such as wheat, maize, or rice. It is not automatically healthier; carbohydrates are usually replaced by potatoes, peas, or legumes. Grain-free is only medically necessary for the small number of pets with a confirmed grain allergy.

"Hypoallergenic" is not a protected term in the same way, but the FEDIAF Code expects it to be backed by a recipe that genuinely reduces allergen exposure—for example, hydrolyzed protein or a single novel protein source. Look for an explanation on the pack or on the brand's website.

4.3 Functional and health claims

Claims like “supports joint health," “promotes a shiny coat," or “aids digestion” are allowed if they are truthful, not misleading, and supported by evidence. They cannot, however, claim to prevent, treat, or cure disease—that wording is reserved for veterinary medicines and for specific dietetic foods sold under the “PARNUTs” regime (particular nutritional purposes), which has its own labeling rules.

If you see a serious-sounding claim such as “dietary management of struvite stones," the product is regulated as a dietetic pet food, and the label must include the recommended feeding period and a note to consult a vet before use.

5. What is changing: digital labels, sustainability and the 2026 outlook

Pet food labeling does not stand still. A few trends are reshaping what you will see on European packs over the next year or two.

5.1 Digital labelling and QR codes

Pack space is finite, and the list of mandatory information keeps growing. FEDIAF and several EU member states have been piloting “digital labeling"—using a QR code on a pack to take you to a web page with the full ingredient list, sourcing information, sustainability data, and feeding calculators. The non-negotiable particulars (name, complete/complementary, composition summary, analytical constituents, additives, net weight, best-before, batch, and manufacturer) still have to be physically on the pack, but extra detail can live online.

If you scan a QR code on a bag of food and land on a brand-controlled page rather than a marketing micro-site, that is usually a sign the brand is taking transparency seriously.

5.2 Sustainability claims

Following the EU's Green Claims Directive and broader anti-greenwashing rules, vague claims like “eco-friendly” or “climate-positive” are increasingly being challenged. FEDIAF has issued guidance encouraging brands to use specific, evidence-based language: for example, “Recyclable mono-material pouch — check local facilities” rather than “green packaging”, or “25% lower carbon footprint per kg vs our 2020 baseline, verified by [third party]” rather than “low carbon”. Expect to see more of this precise framing on pack.

5.3 Insect protein, novel ingredients and clearer allergen flagging

Insect-based proteins (such as black soldier fly larvae) and other novel ingredients are now firmly established in EU pet food. They must be declared in the composition like any other ingredient, and brands are increasingly highlighting them as a sustainability story. At the same time, FEDIAF guidance is pushing for clearer flagging of common allergens to help owners of sensitive pets shop with confidence.

5.4 The 2026 review of EU feed labelling

The European Commission is reviewing parts of Regulation 767/2009, with a particular focus on harmonizing digital labeling, sustainability claims, and feeding guidance. None of this changes the fundamentals — the mandatory particulars are not going away — but expect labels to become more standardized and, crucially, more comparable between brands.

6. A 60-second checklist for the pet food aisle

Next time you are standing in front of a wall of bags and tins, run through these questions:

• Is it labelled complete or complementary, and is that what you want?

• Does the species and life stage match your pet (e.g., adult cat, large-breed puppy)?

• Is the named protein on the front actually high in the composition list, and what percentage is declared?

• Where does the product sit on the flavor / with / rich in / [ingredient] ladder?

• Does the analytical constituents table look reasonable for the type of food (dry vs wet, kitten vs senior)?

• Are vitamins, minerals, and any preservatives clearly listed under additives?

• Is there a clear feeding guide, batch number, best-before date, and manufacturer address?

• Do any health or sustainability claims feel specific and verifiable, or vague and emotional?

If a product passes most of these checks, you can be reasonably confident you are looking at a label that takes FEDIAF guidance — and your pet — seriously.

Final thought

European pet food labeling can look intimidating, but it is built around a simple idea: you should be able to look at a pack and know exactly what is in it, who made it, who it is for, and how to feed it. FEDIAF's job is to keep that promise honest as the science, the supply chain, and the legislation evolve.

The next time you pick up a bag of food, give the back of the pack a proper minute of attention. Your dog or cat cannot read the label — but now you can.

Frequently Asked Questions

What is the difference between a “complete” and a “complementary” pet food?

A complete food is designed to be the sole source of nutrition and, fed in the right quantity, provides everything your pet needs. A complementary food — such as treats, toppers, broths, and many wet foods — is meant to be fed alongside other food and is not nutritionally balanced on its own.

What do “with chicken” and “rich in chicken” actually mean?

These wordings follow a strict FEDIAF hierarchy by percentage of the named ingredient: “chicken flavour” means under 4%, “with chicken” at least 4%, “rich in chicken” at least 14%, and naming it outright (e.g. “Chicken dinner”) requires at least 26%. Knowing this ladder is the single most useful trick when shopping for European pet food.

Does “grain-free” mean a food is healthier?

Not automatically. Grain-free simply means the recipe contains no cereals such as wheat, maize, or rice, with carbohydrates usually replaced by potatoes, peas, or legumes. It is only medically necessary for the small number of pets with a confirmed grain allergy.
