Our verdict

Is Royal Canin West Highland White Terrier Adult a good dog food?

We score it 43/100 (Poor). The main reasons are set out in "Why you might not" below, and every step of the calculation is shown under "How we calculated this score".

Complete extruded dry food for adult dogs, with corn flour, dehydrated poultry proteins and rice as the main ingredients.

How we score

Only part of the analytical constituents are declared, so the nutritional picture is incomplete.

99% of this recipe has no printed percentage. Estimated shares are model estimates, not label facts.

Why you might choose it

  • Prints ingredient percentages on the label.
  • Nutritionally complete: formulated to be fed as the whole diet.

Why you might not

  • 4 poor-graded ingredients make up about 22% of the recipe.

Who is this food for?

Suits

  • Labelled by the manufacturer for adult dogs
  • Doesn't list beef, lamb, venison, duck as ingredients

Consider something else if:

  • Your dog avoids chicken: the label lists dehydrated poultry proteins
  • Your dog avoids turkey: the label lists dehydrated poultry proteins
  • Your dog avoids fish: the label lists fish oil
  • Your dog avoids pork: the label lists dehydrated pork protein
  • Your dog avoids grain: the label lists maize flour
  • 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 a final score of 43 out of 100 based on several key factors. The overall quality of the ingredient list added +4.2 points. However, ingredients without printed percentages reduced the score by -10.5. Additionally, the processing format deducted -6.7 and the carbohydrate content contributed -3.4.

Scored with model v3 on 2026-10-25. Each component is the feature value for this product multiplied by the model's published coefficient.

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.

NutrientAs fed (label)Dry matter (scored)Score
Protein2123.2 (band 18 to 40%)84.2
Fat1617.7 (band 5.5 to 20%)100
Fibre1.41.5 (band 0.5 to 5%)84

Scored over 3 declared nutrients (combined weight 50); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 9.5% from the food type.

Declared fortification: 8 nutritional additives on the label
  • Vitamin A: 29800 IU
  • Vitamin D3: 800 IU
  • Iron (3b103): 97 mg
  • Iodine (3b201, 3b202): 5.8 mg
  • Copper (3b405, 3b406): 6 mg
  • Manganese (3b502, 3b504): 62 mg
  • Zinc (3b603, 3b605, 3b606): 140 mg
  • Selenium (3b801, 3b811, 3b812): 0.3 mg

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.

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.
