Our verdict
Is Diamond Pet Foods Weight Management Formula 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.
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
- Grain-free: no grain ingredients listed
- Doesn't list beef, turkey, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists chicken oil and fat
- Your dog avoids lamb: the label lists lamb
- Your dog avoids fish: the label lists fish meal
- 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. 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 | 22 | 24.3 (band 18 to 40%) | 87.2 |
| Fat | 8 | 8.8 (band 5.5 to 20%) | 83.8 |
| Fibre | 10 | 11 (band 0.5 to 5%) | 100 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 298 | 329.3 | 100 |
Fibre: Declared as a maximum; the high-fibre taper is not applied.
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.
Declared fortification: 30 nutritional additives on the label
- Zinc 150 mg/kg Minimum

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 |
