How to Read a Dog Food Label — What the Jargon Actually Means

Walk into any pet shop and you'll be confronted with bags making claims like "natural," "holistic," "ancestral recipe," and "grain-free." Almost none of these terms have regulatory definitions. Here's what actually matters when evaluating a dog food.

The Ingredient List

Ingredients are listed in descending order by weight before cooking. This means a food listing "chicken" first has more chicken than anything else — but "chicken" loses about 75% of its weight when cooked, while "chicken meal" is already dried. A food with "chicken meal" third on the list may contain more actual chicken protein than one with "fresh chicken" first.

The Guaranteed Analysis

This panel shows minimum protein and fat percentages, and maximum fibre and moisture. To compare foods on a dry-matter basis (removing moisture differences), divide each nutrient by (100 minus the moisture percentage).

The AAFCO Statement

Look for foods stating "formulated to meet AAFCO nutrient profiles" or "tested in AAFCO feeding trials." The former means the formula meets minimum nutrient levels on paper; the latter means it was actually fed to real dogs — a stronger indicator of quality.
