"Natural," "premium," and "with real chicken" mean almost nothing on a pet food bag. The ingredient list and the guaranteed analysis are where the truth lives.
Read the first five ingredients
Ingredients are listed by weight. The first five make up the bulk of the food. A named protein (chicken, salmon, beef) in the top two slots is what you want — not "meat by-products" or "animal digest".
Understand the guaranteed analysis
This is the block listing minimum protein and fat, and maximum fibre and moisture. It tells you what's in the bag, not necessarily how digestible it is — two foods with identical percentages can perform very differently depending on ingredient quality. Use it to compare similar products, not as the final word.
By-products aren't automatically bad — but vagueness is
"Chicken by-product meal" (a named source) is a legitimate, nutrient-dense ingredient used in many good foods. "Meat by-products" or "animal digest" with no named animal is the red flag — it means the manufacturer isn't committing to what's actually inside.
Find the life-stage statement
"Complete and balanced for [life stage]" is the line that matters, usually printed near the guaranteed analysis. Without it, the food is supplemental at best — fine as a topper, not as the whole diet.
What label claims to trust less
"Vet recommended," "gourmet," and "holistic" carry no regulatory meaning. If a claim matters to you — grain-free, limited-ingredient, prescription-grade — verify it against the ingredient list yourself rather than trusting the front of the bag.
