- Transparency60
- Safety100
- EvidenceNot recorded
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
- Declares energy content, which most labels omit.
- Nutritionally complete: formulated to be fed as the whole diet.
Why you might not
- 4 poor-graded ingredients make up about 21% of the recipe.
- 100% of the recipe mass has no printed percentage, so the exact split cannot be verified.
- Its additive load costs about 4 points in the rating.

Who is this food for?
Suits
- Labelled by the manufacturer for senior dogs
- Labelling or feeding guide is aimed at large dogs
- Doesn't list lamb, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists chicken
- Your dog avoids beef: it is listed as an ingredient
- Your dog avoids turkey: the label lists poultry
- Your dog avoids fish: the label lists fish meal
- Your dog avoids grain: the label lists rice - white
- 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.

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 | 29 | 32 (band 18 to 40%) | 100 |
| Fat | 14 | 15.5 (band 5.5 to 20%) | 100 |
| Fibre | 4 | 4.4 (band 0.5 to 5%) | 100 |
| Energy (kcal/100g) | 374 | 413.3 | 100 |
Scored over 4 declared nutrients (combined weight 60); 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) - 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.
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.
Claims on file; none we can check against the label
| Claim | Type | Check | Substantiation |
|---|---|---|---|
| support for joint health and mobility (glucosamine and EPA for joint health and mobility) (on page) | Functional | not checkable | Manufacturer assertion |
| Omega-6 fatty acids and vitamin A to nourish skin and coat health (on page) | Functional | not checkable | Manufacturer assertion |
| high quality protein to help support strong muscles, including a healthy heart (on page) | Functional | not checkable | Manufacturer assertion |
| Highly digestible large breed dog food formula for optimal nutrient delivery (on page) | Functional | not checkable | Manufacturer assertion |
