How we read this label, and what we don’t penalize
- Are by-products actually bad for dog food?"No by-products" is one of the most effective marketing lines in the pet aisle. By AAFCO's definition, a named by-product is mostly organ meat. PetScored does not penalize it, and here is the reasoning.
- Chicken meal vs chicken: is "meal" a cheap filler?A bag that lists fresh chicken first sounds better than one that lists chicken meal. Because of how the ingredient list is weighed, the opposite is often true.
- Feeding trials vs "formulated to meet": the AAFCO line that decides a lot.Every complete dog food carries an AAFCO statement, and it comes in two flavors. One means the recipe was calculated on paper. The other means dogs actually ate it for six months. Our rubric weighs them differently.
- Wet vs dry dog food: what the rubric actually rewards.Format is the first thing buyers argue about and nearly the last thing our rubric cares about. Wet and dry both show up near the top and the bottom. Here is what the scorecard is really reacting to.
- Is fresh dog food better than kibble?Fresh, gently cooked food is more digestible than kibble in controlled studies. Whether that buys your dog better health, at several times the price, is a separate question the evidence has not answered.
- Is raw dog food worth it?Raw feeding promises a shinier coat and better health. In the peer-reviewed record the balance runs the other way: the risks are measured and repeated, the benefits are not.
- How much protein does a dog actually need?The protein percentage on the front of the bag is not the number you think it is. Here is how to read it on a dry-matter basis, and what the regulatory floor actually is.
This score is our opinion, formed by applying a published rubric to label and public source records, not a statement of objective fact and not veterinary advice. Label fields we cannot verify are marked by source confidence rather than assumed. See the methodology and medical disclaimer.
