Is Open Farm RawMix Open Prairie Recipe-Ancient Grain for Dogs a good dog food?

We score it 51/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.

How we score

Why this score?

This recipe achieves an overall score of 51 out of 100 based on several key factors. On the positive side, the overall quality of the ingredient list adds +6.5 points, and printing percentages for most of the recipe contributes +2 points. However, the score is reduced by -13.1 points due to ingredients without printed percentages, and the processing format subtracts -7 points.

Only part of the analytical constituents are declared, so the nutritional picture is incomplete.

100% of this recipe has no printed percentage. Estimated shares are model estimates, not label facts.

The Recipe score measures how attractive and transparent the declared ingredient list is. It is not, by itself, proof that the food is nutritionally appropriate for long-term feeding. The Nutritional and Evidence scores measure what we can verify towards that stronger claim.

Complete extruded dry food for dogs of all life stages, with chicken, turkey and fish meal as the main ingredients.

Why you might choose it

High in protein: 34% protein on a dry-matter basis.
Declares energy content, which most labels omit.
Nutritionally complete: formulated to be fed as the whole diet.

Why you might not

100% of the recipe mass has no printed percentage, so the exact split cannot be verified.

Who is this food for?

Suits

Labelled by the manufacturer for all lifestages
Doesn't list beef, lamb, venison, pork, duck as ingredients

Consider something else if:

Your dog avoids chicken: the label lists chicken
Your dog avoids turkey: the label lists turkey
Your dog avoids fish: the label lists fish meal
Your dog avoids grain: the label lists barley
You want a single-protein recipe: this one lists more than one animal protein

These points are derived from declared ingredients and analysis, not a substitute for veterinary advice. If your dog has a diagnosed condition, food choice is a medical nutrition decision: speak to your vet. Use the homepage filter to find foods that fit your dog.

Score history across model versions

The score shown above is always computed with the latest published model. Earlier scores are kept for the record and are never edited or deleted; a scoring change ships as a new model version with a public write-up on the methodology page.

Nutritional: declared analysis vs reference ranges

How the declared analysis compares with FEDIAF reference ranges for adult dogs. The label prints as-fed values; we convert to a dry-matter basis before scoring, and the bands are dry-matter ranges. Scores rise to 100 at the band midpoint: the reference is adequacy, not maximisation. Nutrients with a published upper limit taper again above it; fat is policed through calorie density rather than a direct penalty.

Nutrient	As fed (label)	Dry matter (scored)	Score
Protein	31	34.4 (band 18 to 40%)	100
Fat	17	18.9 (band 5.5 to 20%)	100
Fibre	4.5	5 (band 0.5 to 5%)	100
Calcium	1.2	1.3 (band 0.5 to 2.5%)	95
Phosphorus	1	1.1 (band 0.4 to 1.6%)	100
Calcium:phosphorus ratio	1.2	1.2 (band 1 to 2%)	82
Omega fatty acids (omega-6 and omega-3)	-	-	100
Energy (kcal/100g)	385	427.8	100

Omega fatty acids (omega-6 and omega-3): scored as the mean of its declared components (omega-6 100). The FEDIAF minimum for omega-6 is linoleic acid specifically.

Scored over 8 declared nutrients (combined weight 100); undeclared nutrients do not affect the score.

Low confidence: partial analysis or moisture estimated from the food type.

This measures agreement with published reference ranges, not suitability for an individual dog. For medical conditions, follow veterinary guidance.

Transparency: what the label discloses

How much the manufacturer discloses, measured against the FEDIAF Code of Good Labelling Practice and Regulation 767/2009. Mandatory items dominate the weighting.

Item	Points
✓ Ingredient list on the label (mandatory)	10/10
✗ Printed percentages on the label (voluntary) - not on file	0/20
✗ Analytical constituents declared (mandatory) - not on file	0/15
✓ Additives declared (mandatory)	10/10
✓ Energy value declared (voluntary)	5/5
✓ Complete/complementary designation (mandatory)	5/5
✓ Feeding guidance given (mandatory)	10/10
✓ Manufacturer identity and address (mandatory)	5/10
✓ Country of manufacture stated (voluntary)	10/10
✗ Batch and date labelling (mandatory) - not on file	0/5

Capped at 60: mandatory items missing (Analytical constituents declared, Batch and date labelling).

Safety: recall history

Recall and safety-notice history, time-decayed. This dimension is shown alongside the score and never feeds the headline number.

Evidence: what the brand claims, and what supports it

The marketing claims made on the pack and product page, and how much evidence sits behind them. We record the claims as stated; we do not assess whether they are true.

Claim	Type	Substantiation
Non-GMO pumpkin (on pack)	Content	Manufacturer assertion
Humanely-raised chicken, organs & bone (on pack)	Content	Manufacturer assertion
Non-GMO brown rice (on pack)	Content	Manufacturer assertion
Non-GMO whole-grain barley (on pack)	Content	Manufacturer assertion

No corn, wheat, or soy (on pack)	Free-from	Manufacturer assertion

Limited: at least one claim rests on manufacturer assertion alone.
