How to read a pet food label

The ingredient list is ordered by weight — including water

Ingredients are listed heaviest first, weighed before cooking. That order is regulated, and it's the closest thing to honesty on the bag — but it counts water weight. Fresh chicken is roughly 70% water, so it can sit proudly at the top while a chicken meal further down actually contributes more protein once everything is cooked.

The first five ingredients tell most of the story. Named sources — chicken, salmon meal, beef liver — put the species on record. Generic ones — 'meat', 'poultry by-product', 'animal fat' — don't, and what's behind them can change batch to batch.

Watch for ingredient splitting

One base ingredient can appear as several fractions — peas, pea protein, pea starch, pea fiber — so each lands lower on the panel than the whole would have. Add the fractions back together in your head: a food that reads meat-first can be legume-first in practice.

The guaranteed analysis is a floor and a ceiling, not a recipe

'Crude protein (min) 26%' guarantees at least 26% — the real figure can be higher. Protein and fat are stated as minimums; fiber and moisture as maximums. None of it says anything about digestibility or where the protein comes from.

And two bags' percentages aren't comparable when their moisture differs — a wet food's 10% protein can out-protein a kibble's 30% once the water is removed. That's dry-matter basis, and it has its own guide below.

Find the nutritional adequacy statement

Somewhere in the small print is the sentence that matters most: whether the food is complete and balanced for a life stage, and how the company backs that up — formulated to meet AAFCO nutrient profiles, or substantiated by actual AAFCO feeding trials. Trials are the stronger claim.

'For intermittent or supplemental feeding only' means it is not a complete diet — normal on treats and toppers, a red flag on anything sold as dinner.

Words that sound regulated but aren't

'Premium', 'holistic', 'gourmet' — no legal definition at all. 'Natural' has an AAFCO definition, but a loose one. 'Human-grade' makes a specific claim that is rarely substantiated end-to-end. None of these words tells you anything the ingredient panel doesn't say better.
