Is Harley & Marley Joint Health Super Bites Functional Health Bites a good dog food?

93% 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.
- Single named animal protein: fish.
- Doesn't list grain ingredients.
Why you might not
- A treat, not a complete diet: feed as an extra, not the whole diet.
- Meat makes up an estimated 2% of the dry matter (4% as fed); carbohydrates dominate.
What the label tells us
- The label lists 10 ingredients.
- Names its animal sources (1 named ingredient).
- Every animal ingredient is a named source.
- Lists no artificial colours or preservatives.
- Prints quantities for 6 ingredients.
Why is this treat not scored?
Our 1 to 100 rating applies to complete diets, so treats and complementary foods are presented as what the label tells us rather than a number that would invite comparison with complete meals.
What should I look for on a treat label?
A short ingredient list, named animal sources instead of generic terms, and no artificial colours or preservatives. Printed quantities are a good transparency signal, though few treat labels provide them.
These points are derived from the published ingredient list, not a rating.

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.
| Model | Score | |
|---|---|---|
| v2 | 45/100 | current |
| v1 | 58/100 | |
| v1.9 | 59/100 |
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 (7.5% of the recipe mass) (voluntary) | 1.5/20 |
| Analytical constituents declared (mandatory) - not on file | 0/15 |
| Additives declared (mandatory) - not on file | 0/10 |
| Energy value declared (voluntary) - not on file | 0/5 |
| Complete/complementary designation (mandatory) | 5/5 |
| Feeding guidance given (mandatory) - not on file | 0/10 |
| 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, Additives declared, Feeding guidance given, Batch and date labelling).
