The front of a bag gives you a product name and a set of claims. The back usually contains more of the information needed to decide whether the food belongs on your shortlist. Use this order before comparing price or ingredients.
1. Confirm the exact recipe
Match the brand, recipe, food format and US market. A puppy recipe and an adult recipe in the same product line are separate foods. Package sizes can share a formulation, but an older bag may have a different ingredient list. Keep its lot and date codes.
2. Read nutritional adequacy
Look for the nutritional adequacy statement and the intended life stage. FDA describes two ways to substantiate a complete-and-balanced claim: meeting an AAFCO nutrient profile or passing a feeding trial using AAFCO procedures. That distinction belongs in the record. AAFCO does not approve individual foods.
For a puppy expected to become a large adult dog, check the large-size growth wording explicitly. Do not substitute an adult-maintenance food just because a marketing panel mentions protein or development. Unknown adequacy means eligibility has not been established.
3. Locate calories and quantities
Calories per kilogram allow a consistent energy comparison. Calories per cup describe the manufacturer's measuring unit; a cup is not the same weight across every kibble. A package price alone does not tell you feeding cost. Compare standard prices per 1,000 kcal when the exact package and formulation are documented.
4. Keep guarantees in context
A guaranteed protein minimum is not a typical laboratory analysis. A fat minimum and a fiber maximum do not describe exact daily intake. Our conversions keep these qualifiers and leave missing inputs unknown. More digits in a calculation do not create more reliable source data.
5. Read ingredients and save the label
Use the full ordered list, including fats, meals and flavors, when checking ingredient exclusions. An ingredient not listed is not proof of allergy safety. Preserve the original bag so you can compare a later purchase and match an official recall notice.
A useful shortlist
Keep foods whose documented life stage and purpose fit your dog. Compare evidence, missing information, cost and practical use next. Bring medical needs and unresolved suitability questions to your veterinarian. This guide is educational and does not provide an individualized feeding plan.
