You will know how to read the two parts of the pack that commit the manufacturer, and how to spot the words that commit nobody.
Some links on this page earn us a commission if you buy after clicking. It changes neither the ranking nor what is written here — and we say below what we were unable to check.
One side of the bag is built to persuade, the other to satisfy regulation. They rarely carry the same information, and it is the small side you read.
Ingredients appear from heaviest to lightest. The detail that changes everything: that weight is the weight going in, before manufacturing drives off the water.
Fresh meat carries a lot of water and weighs heavily at the start. After cooking, little of it remains. That is how an ingredient listed first can end up a modest share of the finished food, with no rule broken.
Front-of-pack phrases place a product, they do not describe it. Rich in, with chicken, beef flavour: these carry different obligations, and the difference between them rests on thresholds the reader never sees.
The useful reflex is to turn the bag over and look for a percentage printed next to the ingredient. If there is none, the maker chose not to commit to an amount, and that absence is already an answer.
The small table announcing protein, fat, fibre, ash and moisture is a measurement, not a recipe. It says how much, never where from.
Two foods can show the same protein line while using very different raw materials, and poorly digestible protein passes through the animal without serving it. That is the deep limit of the table, and it is why it cannot rank two products on its own.
A complete food is designed to meet, on its own, the needs of the animal it addresses. A complementary food cannot, and says so: it has to be given alongside something else.
Many of the tastiest products on a pet shop shelf are complementary. Serving them as a meal means building a diet blind, when the wording is printed on the pack.
Premium, holistic, ancestral, vet formula, inspired by nature: none of these matches a checkable specification. They describe a commercial intention.
The test is simple. If a word points to no percentage, no regulated category, and nothing you can verify elsewhere on the bag, it tells you nothing about the contents.
Two important things appear on no pack: how digestible the raw materials really are, and how appealing the food will be to your animal in particular.
Both only show up afterwards, at home, in the stools and in the bowl. That is why a food that reads beautifully on paper can still not suit, and why nobody can choose a food for you from a bag alone.
Percentages are given on the product as sold, moisture included. A pouch and a kibble do not hold the same amount of water, so their protein lines are not read on the same scale.
Comparing wet with dry without correcting for that gap always flatters the dry one, for a reason that has nothing to do with quality. Between two foods of the same type, direct comparison becomes honest again.
