Walk down any pet food aisle and you'll find bags covered in claims: "grain-free", "holistic", "premium", "vet-recommended". Most of it is marketing. The information that actually tells you what's in the food is buried in small print on the back. Here's how to read it.
The Ingredient List: Order Is Everything
Ingredients are listed by weight before processing, heaviest first. A food that lists "chicken" as the first ingredient sounds great, but chicken is about 70% water. After cooking, it may represent far less of the final product than the grain listed third.
What to look for:
- A named protein source in the first two ingredients (chicken, salmon, beef — not "meat meal" or "animal derivatives")
- Whole foods higher up the list than fillers
- Short, recognisable ingredient lists over long ones packed with additives
The Guaranteed Analysis: Four Numbers That Matter
Every label must show minimum crude protein, minimum crude fat, maximum crude fibre, and maximum moisture. These are minimums and maximums, not exact values, so they give you a range rather than a precise picture.
To compare foods fairly, convert to a dry matter basis by removing moisture from the equation. A wet food with 10% protein and 78% moisture has roughly 45% protein on a dry matter basis, far higher than it looks.
Marketing Terms You Can Ignore
These terms have no legal or nutritional definition in most markets:
- "Natural"
- "Holistic"
- "Premium"
- "Human-grade" (unless the facility is certified)
- "Superfood"
They tell you nothing about quality. Focus on the ingredient list and guaranteed analysis instead.
AAFCO Statements: What "Complete and Balanced" Actually Means
Look for a statement from AAFCO (or your regional equivalent) confirming the food meets nutritional standards for a specific life stage. There are two types:
- Formulated to meet — the recipe was calculated to hit nutrient targets, but not tested on animals
- Feeding trials — the food was actually fed to animals and shown to sustain them
Feeding trial foods carry more real-world confidence, though both are considered acceptable. If a food has no AAFCO statement at all, it has not been verified as nutritionally complete.
Practical Checklist: 5 Things to Check Before Buying
- Named protein in the first two ingredients
- AAFCO "complete and balanced" statement for your pet's life stage
- No vague terms like "meat derivatives" high on the list
- Moisture content noted (especially important when comparing wet and dry foods)
- Manufacturer contact details present (a sign of accountability)
A Note on Portion Control
Even the best food causes problems in the wrong quantities. If you feed on a schedule, a tool like the Smart WiFi Dog Feeder 2L takes the guesswork out of portions, especially across multiple daily meals or when you're away from home.
And if you're paying closer attention to what goes into your pet's body, it's worth knowing the signs when something isn't right. Our guide on how to spot early warning signs of illness in your pet covers what to watch for before a problem becomes serious.
