Our verdict
Is Royal Canin US Gastrointestinal Low Fat a good dog food?
We score it 53/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
Declared analysis sits below the FEDIAF minimum for fat.
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, beef, lamb, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids turkey: the label lists turkey
- Your dog avoids fish: the label lists fish oil
- Your dog avoids grain: the label lists rice - brown / whole grain
- 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 total score of 53 out of 100 based on several key factors. The presence of ingredients without printed percentages contributed -10.6 to the overall rating, while the overall quality of the ingredient list added +5.4. Furthermore, the additive load contributed -4.7, and the additives in the recipe adjusted the score by +3.1.
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.
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 | 28.6 (band 18 to 40%) | 98.8 |
| Fat | 1.3 | 4.6 (band 5.5 to 20%) | 59.1 |
| Fibre | 4.5 | 16.1 (band 0.5 to 5%) | 100 |
Fibre: Declared as a maximum; the high-fibre taper is not applied.
Scored over 3 declared nutrients (combined weight 50); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 72% 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) | 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 |

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.
