Lowest-carbohydrate dog foods (estimated)

Captured 2026-07-25

US labels don't have to state carbohydrate, so it is estimated the standard way — 100 minus protein, fat, fibre, moisture and an assumed ash figure. That assumption is why every number here carries a tilde. Foods missing any input are excluded rather than guessed at. How the estimate works.

The order is one number estimated the same way for every row, sorted low to high. It is not a score, not a shortlist and not a recommendation: no row here is endorsed over any other, and a food's position tells you what its label allows us to infer, not whether it suits your dog.

How to read an estimated ranking

No number in the sorted column was published by anyone. Carbohydrate is not a required disclosure on a US pet food label and effectively nobody volunteers it, so each figure here is nitrogen-free extract computed by difference — carbohydrate ≈ 100 − protein − fat − fibre − moisture − ash — and then converted to a dry-matter basis. Ash is not on the label either: we assume 8% below 50% moisture and 2.5% above it, which is written out in the methodology, marked est. in the column header, and drawn hatched in every composition strip on the site.

That makes this the least certain list here, and it inherits every soft edge in its inputs. Protein and fat are guaranteed minimums while fibre and moisture are guaranteed maximums, so a brand that publishes conservative guarantees produces a high carbohydrate estimate and moves down the table for reasons of labelling policy rather than recipe. Two foods a percentage point apart are not distinguishable by this method: read the ranking as bands, not as positions.

17 of the 122 foods are missing at least one of the four published inputs, so no estimate exists for them and none was invented — those manufacturers are named instead. 18 of the 40 rows share their value with at least one other row, and ties are broken alphabetically, which means the order inside a tie carries no information. The table stops at 40 rows; the other 65 eligible formulas are in the full index.

What the order does not mean: a lower estimate is not a better food, and low-carbohydrate is not a health claim this site will make on a dog's behalf. 20 of the 40 rows here carry a grain-free claim, which is a labelling fact and not a carbohydrate level — the two are tracked separately for that reason. An estimate built on an assumption cannot carry a verdict, which is why the assumption is printed beside it.
