Our verdict
Is Dr. Clauder's Basic Nature Marathon HGA a good dog food?
We score it 46/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
Complete extruded dry food for adult dogs, with wheat, barley and rice as the main ingredients.
Only part of the analytical constituents are declared, so the nutritional picture is incomplete.
64% 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 lamb, venison, duck as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists dehydrated poultry proteins
- Your dog avoids beef: the label lists pork protein and beef protein
- Your dog avoids turkey: the label lists dehydrated poultry proteins
- Your dog avoids fish: the label lists fish meal
- Your dog avoids pork: the label lists pork protein and beef protein
- Your dog avoids grain: the label lists wheat
- 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.

Recipe: how the 1-100 score is calculated
Why this score?
This recipe achieves an overall score of 46 out of 100 based on several key factors. The meat content contributed +2.6 to the evaluation. Conversely, ingredients without printed percentages reduced the score by -6.7, the processing format adjusted it by -6.7, and the carbohydrate content contributed -3.5.
Scored with model v3 on 2026-10-25. Each component is the feature value for this product multiplied by the model's published coefficient.

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 | 26 | 28.7 (band 18 to 40%) | 99.3 |
| Fat | 16 | 17.7 (band 5.5 to 20%) | 100 |
| Fibre | 2.5 | 2.8 (band 0.5 to 5%) | 100 |
| Calcium | 1.75 | 1.9 (band 0.5 to 2.5%) | 100 |
| Phosphorus | 1.25 | 1.4 (band 0.4 to 1.6%) | 100 |
| Sodium | 0.25 | 0.3 (band 0.1+%) | 100 |
| Calcium:phosphorus ratio | 1.4 | 1.4 (band 1 to 2%) | 94 |
Scored over 7 declared nutrients (combined weight 85); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 9.5% from the food type.
Declared fortification: 16 nutritional additives on the label

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 (36.2% of the recipe mass) (voluntary) | 7.2/20 |
| Analytical constituents declared (mandatory) - not on file | 0/15 |
| Additives declared (mandatory) | 10/10 |
| Energy value declared (voluntary) - not on file | 0/5 |
| 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.

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
