Dry Extruded complete
Is Merrick Pet Care Grain Free Real Duck & Sweet Potato Recipe Dry Dog Food a good dog food?
We score it 49/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
Why this score?
This recipe achieves an overall rating of 49 out of 100 based on several key factors. The overall quality of the ingredient list contributed +6.1 points to the total. However, ingredients without printed percentages reduced the score by -10.6, the processing format subtracted -6.7, and the additive load contributed -2.4 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.
Why you might choose it
- Doesn't list grain ingredients.
- 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.
- Its additive load costs about 2 points in the rating.

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.
Guaranteed-analysis FEDIAF score: crude minimums and maximums are bounds, not typical values; moisture (a maximum) uses the processing median where available; experimental US score.
| Nutrient | As fed (label) | Dry matter (scored) | Score |
|---|---|---|---|
| Protein | 34 | 37.6 (band 18 to 40%) | 100 |
| Fat | 17 | 18.8 (band 5.5 to 20%) | 100 |
| Fibre | 3.5 | 3.9 (band 0.5 to 5%) | 100 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 368 | 406.6 | 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 5 declared nutrients (combined weight 70); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 9.5% from the food type.
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) | 10/10 |
| Country of manufacture stated (voluntary) | 10/10 |
| Batch and date labelling (mandatory) | 5/5 |
Capped at 60: mandatory items missing (Analytical constituents declared).
Safety: recall history
Recall and safety-notice history, time-decayed. This dimension is shown alongside the score and never feeds the headline number.
No recalls recorded in our database.
Evidence: what the brand claims, and what supports it
The claims made on the pack and product page, checked against the declared label. We record claims as stated; "consistent" means our stored label data supports the claim, "contradicted" means it conflicts with it. Functional claims are recorded but never scored.
100/100 · moderate — 2 checkable claims: 2 consistent, 0 contradicted.
Consistent with the label
- "complete and balanced" — supported by the declared complete and balanced data.
- "66% of protein from animal sources" — supported by the declared high protein data.
7 further claims on file that we cannot check against the label.
Moderate: every checkable claim is consistent with the declared label.

| Real deboned duck is always the first ingredient (on pack) | Content | not checkable | Manufacturer assertion |
| omega-6 and omega-3 fatty acids to nourish skin and coat (on pack) | Functional | not checkable | Manufacturer assertion |
