What do these mean? ▾

Beneficial. Linked to benefits in published research. Tiers show evidence strength.

Restricted or banned. Restricted or banned by a regulator in at least one country.

Under research review. Being studied or re-evaluated by researchers or regulators.

Contextual. Not flagged, but there is a note worth reading.

Standard. Everyday components like vitamins and minerals.

Not yet classified. Not in our dictionary yet. Always still listed.

Counts include what's inside compound entries like vitamin premixes, so they can add up to more than the label's ingredient count.

1ChickenNamed single-species whole meat▾

● Beneficial (well-established)Whole meat from a named animal species. Both the species and the form are identified, which supports traceability and allergy checking. Published nutrition references associate named whole meats with high protein quality.Sources: AAFCO 2024 · NRC 2006 · Amino acid bioavailability studies

2Cracked Pearled BarleyBarley▾

● Contextual noteA whole grain carbohydrate and fibre source. Provides beta-glucans, a type of soluble fibre associated with gut health benefits.Sources: Veterinary nutrition references

3Brown RiceRice / brewer's rice▾

● Contextual noteA highly digestible carbohydrate. Brewer's rice is a milling by-product but still provides nutritional value.Sources: NRC 2006

4Pea FiberPea protein / pea starch / pea fibre▾

● Contextual noteFractionated legume derivatives that can be used to increase the protein reading on a guaranteed analysis without providing a complete amino acid profile. More relevant than whole peas to the FDA's DCM investigation (2018-2022, no causal link established).Sources: FDA DCM Investigation 2018-2022

5Corn Protein MealCorn / corn gluten meal▾

● Contextual noteA digestible carbohydrate and protein source for most dogs. Commonly characterised as filler in consumer discussions, but veterinary nutrition research supports its nutritional value.Sources: AAFCO 2024 · NRC 2006

6Chicken MealNamed species meat meal▾

● Beneficial (well-established)Rendered meal from a named animal species: a concentrated protein source with water and fat removed. The species is identified, which supports traceability and allergy checking.Sources: AAFCO ingredient definitions · Veterinary nutrition references

7Dried Tomato PomaceTomatoes▾

9Chicken Liver FlavorNamed organ meats▾

● Beneficial (well-established)Organ meat from a named animal species, with both the species and the organ identified. Published nutrition references describe named organ meats (e.g. chicken liver, beef heart) as nutrient-dense, naturally rich in vitamins A and B12, iron, copper, and folate. Where the label names only the organ (e.g. "liver"), the animal species is not identified.Sources: NRC 2006 · Nutritional composition data

10FlaxseedFlaxseed / flaxseed oil▾

● Beneficial (supported)A plant-based source of omega-3 (ALA), fibre, and lignans. Note: dogs have limited ability to convert plant ALA to the more bioactive EPA/DHA found in marine sources.Sources: Bauer 2011

This product lists 2 separate rice derivatives (rice, brown rice). When listed separately, each appears lower on the ingredient list than they would if combined as a single entry.

This manufacturer publishes its analysis on a dry-matter basis (with moisture removed), so the values above are shown on that basis and moisture is not stated. AAFCO minimums are also dry-matter figures, so they compare directly; the comparison is shown for context only. Consult your vet for diet decisions.
