Dry Extruded · completeHigh meatClear label
Our verdict
Is Wolf of Wilderness "Ruby Midnight" Beef & Rabbit - Grain-Free a good dog food?
We score it 65/100 (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.
58% 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 all lifestages
- Grain-free: no grain ingredients listed
- Doesn't list chicken, turkey, lamb, venison, duck as ingredients
Consider something else if:
- Your dog avoids beef: the label lists beef
- Your dog avoids fish: the label lists salmon oil
- Your dog avoids pork: the label lists pork
- 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.

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 | 25 | 27.6 (band 18.149171270718234 to 40%) | 96 |
| Fat | 16.5 | 18.2 (band 5.545580110497237 to 20%) | 100 |
| Fibre | 3 | 3.3 (band 0.5 to 5%) | 100 |
| Calcium | 1.35 | 1.5 (band 0.5041436464088398 to 2.5%) | 99.7 |
| Phosphorus | 0.9 | 1 (band 0.40331491712707185 to 1.6%) | 99.6 |
| Calcium:phosphorus ratio | 1.5 | 1.5 (band 1 to 2%) | 100 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 365 | 403.3 | 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. Moisture was not declared and was estimated at 9.5% from the food type.
Declared fortification: 18 nutritional additives on the label
- Vitamin A (19,000 IU)
- vitamin D3 (1125 IU)
- vitamin E (440 IU)
- vitamin C (100mg)
- vitamin B1 (3.9mg)
- vitamin B2 (6.9mg)
- vitamin B6 (7.1mg)
- vitamin B12 (0.25μg)
- niacinamide (46.5mg)
- calcium D-pantothenate (19.6mg)
- biotin (0.4mg)
- folic acid (0.35mg)
- choline chloride (2400mg)
- copper [copper(II) protein hydrolysate chelate] (10.6mg)
- zinc [protein hydrolysate zinc chelate] (87.5mg)
- manganese [protein hydrolysate manganese chelate] (25.5mg)
- iron [iron(II) protein hydrolysate chelate] (52mg)
- iodine [potassium iodide] (1.3mg)
Medium confidence: the full five-part analysis is on file; where moisture was not declared it was 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 (42.2% of the recipe mass) (voluntary) | 8.4/20 |
| 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).

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.
