Our verdict
Is Royal Canin Adult Digestion Supplement a good dog food?

Complementary extruded dry supplement for adult dogs, with wheat, dehydrated poultry proteins and glycerine as the main ingredients.
97% 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 beef, lamb, fish, venison, pork, 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 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.

Contributions are rounded to two decimals, so they may not sum exactly to the subtotal. The full coefficient table is published on the methodology page.
This is not a complete diet, so the 1-100 rating does not apply to it. Read the recipe breakdown above as ingredient-quality context only.
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
Not applicable to complementary food. FEDIAF reference ranges apply to complete diets.
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 (2.9% of the recipe mass) (voluntary) | 0.6/20 |
| Analytical constituents declared (mandatory) | 15/15 |
| 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) | 5/5 |
Safety: recall history

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.
