Dog food packaging is one of the most sophisticated pieces of marketing in any supermarket. Photographs of raw steak and fresh vegetables, words like ancestral and natural, and a front panel engineered to make you feel like a good owner.
None of it is regulated the way you might assume. Here is what to actually look at.
The most important line is not the ingredients
It is the nutritional adequacy statement, and it is usually in tiny print on the back.
You are looking for wording that says the food is complete and balanced for a particular life stage, and that this has been established either by formulation to a recognised standard or, better, by feeding trials.
If a product does not carry a statement like this, it is not a complete diet. That is fine for a topper or a treat, and not fine as the only thing your dog eats.
The life stage matters too. Growth, adult maintenance, and all life stages are not interchangeable. A large-breed puppy in particular needs a food formulated for large-breed growth, because calcium levels affect skeletal development.
Why the ingredient list misleads
Ingredients are listed by weight before cooking. That single detail is responsible for most of the confusion.
**Fresh meat is mostly water.** Fresh chicken at the top of the list may be around 70% water. Once cooked, it contributes far less than it appears to. A named meat meal — chicken meal, lamb meal — is the same meat with water already removed, so it is more concentrated than its position suggests, despite sounding less appealing.
**Ingredient splitting.** A manufacturer can list peas, pea protein, pea fibre and pea starch separately. Each appears low down, but combined they may outweigh the meat at the top.
**By-products are not automatically bad.** The term covers organ meats — liver, kidney, spleen — which are nutrient dense and exactly what a wild canid eats first. Unnamed by-products give you less information, but the word itself is not a red flag.
The words with no legal meaning
Treat these as decoration rather than information:
- **Premium, super-premium, gourmet** — no defined standard
- **Holistic** — means nothing in this context
- **Human grade** — has a specific meaning in some jurisdictions and none in others
- **Ancestral or biologically appropriate** — marketing language
- **Natural** — loosely defined at best
- **No fillers** — filler has no agreed definition
What the guaranteed analysis does and does not tell you
The panel gives minimum protein and fat, maximum fibre and moisture. Useful, with two caveats.
First, you cannot compare wet and dry food directly, because moisture differs enormously. To compare properly you convert to a dry matter basis: divide the nutrient by the total dry matter. A wet food at 10% protein and 78% moisture is 45% protein on a dry matter basis — far higher than it looks.
Second, protein quantity says nothing about quality or digestibility. A high number can come from sources your dog absorbs poorly.
The number nobody prints prominently
Calories. Look for the kcal per kilogram or per cup figure. Two foods with identical analyses can differ substantially in calories, which is precisely how portion sizes go wrong.
Questions worth asking a manufacturer
The most useful single filter is whether the company employs a qualified nutritionist and conducts feeding trials. Reputable manufacturers answer this readily. Companies that cannot say who formulated their food have told you something.
Storage matters more than people think
Fat goes rancid. Keep food in its original bag — the liner is designed as a fat barrier — and put the whole bag inside a container rather than tipping kibble loose into one.

Sealed, wheeled container for large bags. Keep the food in its own liner inside it rather than pouring kibble straight in.

The honest summary
Check the adequacy statement and life stage first. Convert to dry matter before comparing anything. Treat the front panel as advertising, and judge a brand by whether it can tell you who formulated the food and whether it was tested.
