Who is this food for?
Suits
- Labelled by the manufacturer for adult dogs
- Doesn't list beef, lamb, 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 fish: the label lists green-lipped mussel
- 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. Use the homepage filter to 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.
Nutritional: declared analysis vs reference ranges

| Printed percentages on the label (8% of the recipe mass) (voluntary) | 1.6/20 |
| 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 |
