Years Healthy Teeth & Happy Joints Beef & Duck Dental Bars
Treat complementary High meat Clear label Full label
Is Years Healthy Teeth & Happy Joints Beef & Duck Dental Bars a good dog food?
This is a treat, not a complete diet, so it is not scored on our 1-100 scale. The ingredient breakdown below shows what is in it; a treat should be fed alongside, not instead of, a complete diet.
- RecipeNot applicable
- NutritionalNot applicable
- Transparency60
- Safety100
- Evidencelimited33
Complementary extruded dry treats for dogs of all life stages, with beef skin, duck and green as the main ingredients.
Why you might choose it
- Meat makes up an estimated 96% of the dry matter (99% as fed).
- Prints ingredient percentages on the label.
- Prints a percentage for nearly every ingredient, so the recipe is fully auditable.
Why you might not
- A treat, not a complete diet: feed as an extra, not the whole diet.
What the label tells us
- The label lists 4 ingredients.
- Names its animal sources (1 named ingredient).
- Uses generic terms (Duck): the specific animal source is not stated.
- Lists no artificial colours or preservatives.
- Prints quantities for 2 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 | 75/100 | current |
| v1 | 70/100 | |
| v1.9 | 70/100 |
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 (98.6% of the recipe mass) (voluntary) | 19.7/20 |
| Analytical constituents declared (mandatory) | 15/15 |
| 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 (Additives declared, Feeding guidance given, Batch and date labelling).
