Our verdict
Is Diamond Pet Foods Lamb Dinner a good dog food?
We score it 54/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
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.
Who is this food for?
Suits
- Labelled by the manufacturer for adult dogs
- Doesn't list chicken, turkey, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids beef: the label lists beef liver
- Your dog avoids lamb: the label lists lamb
- Your dog avoids fish: the label lists fish oil
- Your dog avoids grain: the label lists rice flour
- You want a single-protein recipe: this one lists more than one animal protein
- You are limiting fat: 22.7% on a dry-matter basis is in the high band
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. 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 | 8 | 36.4 (band 25.772727272727273 to 40%) | 100 |
| Fat | 5 | 22.7 (band 7.875 to 20%) | 100 |
| Fibre | 1 | 4.5 (band 0.5 to 5%) | 100 |
| Energy (kcal/100g) | 126 | 572.7 | 100 |
Scored over 4 declared nutrients (combined weight 60); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 78% 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) | 5/10 |
| 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.
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 |
|---|---|---|---|
| Prebiotic fiber aids in digestion (on page) | Functional | not checkable | Manufacturer assertion |
| Enhanced with vitamins, minerals and superfoods (on page) | Content | not checkable | Manufacturer assertion |
| Real lamb protein for great taste and nutrition (on page) | Content | not checkable | Manufacturer assertion |
