Free-Range Chicken Hearts | Raw Freeze-Dried Wholefood Treats
This is a treat, not a complete diet. The 1–100 rating applies to complete foods, so it isn't scored. Ingredient breakdown below.

Is Frontier Pets Free-Range Chicken Hearts | Raw Freeze-Dried Wholefood Treats 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.

How we score

Only part of the analytical constituents are declared, so the nutritional picture is incomplete.

Why you might choose it

  • Meat makes up an estimated 100% of the dry matter.
  • 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

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.

Storage

Store in a cool, dry place, away from direct sunlight and moisture. No refrigeration needed. Always reseal the bag tightly after each use to maintain freshness and prevent exposure to air and humidity.

Feeding guide

Serve as-is as a crunchy treat, break into smaller pieces for training rewards, crumble over meals as a meal enhancer, or rehydrate with warm water for a softer texture. Always supervise and ensure fresh water is available.

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

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.

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.

100/100 · moderate — 1 checkable claim: 1 consistent, 0 contradicted.

Consistent with the label

  • "Single-Source Protein - Ideal for pets with dietary sensitivities." — supported by the declared single protein data.

10 further claims on file that we cannot check against the label.

Moderate: every checkable claim is consistent with the declared label.
