In plain English

Merrick Backcountry Raw Infused Puppy Recipe + Grains is a dry food with freeze-dried raw pieces, featuring deboned chicken and chicken as its main proteins, designed for puppies.

This recipe boasts a strong protein profile, starting with deboned chicken, which offers high biological value. It also includes quality carbohydrate sources with declared fiber, and its fat sources are well-defined, featuring marine oil for EPA and DHA.

Nothing concerning in the deck.

Good fit for puppies of all sizes. Nothing serious working against it.

Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.

Who this is for

Strong fit for active large sporting breeds like Golden Retrievers, Labrador Retrievers, and Irish Setters navigating diet-associated DCM concerns. Deboned chicken anchors position 1, with zero pulses in the top 15, plus salmon at position 9. Goldens appeared disproportionately in the FDA's DCM reports. Pulse-heavy grain-free formulas warrant extra caution; named animal protein with organ meat or marine sources is the safer fit.

28 total
Good Neutral Watch Flagged
  1. 1
    deboned chicken

    Real meat with the bones removed before grinding. The cleanest version of chicken on an ingredient label.

    Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.

  2. 2
    brown rice

    Whole grain that's easy to digest. Steady carb energy plus a little fiber.

    Position 2: major carbohydrate source.

  3. 3
    chicken meal

    Chicken with the water cooked out. Per pound, packs more protein than fresh chicken. See why →

    Position 3: significant protein contributor. Adds amino-acid diversity to the top of the deck.

  4. 4
    barley

    Whole grain with a low glycemic profile and some soluble fiber. Easy on blood sugar.

    Position 4: supporting grain. Smaller contribution to the carb deck.

  5. 5
    oat meal

    Alternate spelling of oatmeal. Gentle whole grain, steady carb energy, soluble fiber.

  6. 6
    turkey meal

    Turkey with the water cooked out. Per pound, packs more protein than fresh turkey. See why →

    Position 6: supporting protein. Modest contribution to total protein weight.

  7. 7
    chicken fat

    Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →

    Position 7: trace fat. Below the level that materially shifts the fat profile.

  8. 8
    potato protein

    Concentrated potato protein. Like pea protein, it inflates the protein number without matching meat-quality amino acids.

    Position 8: moderate plant-protein boost. Less likely to materially shift the protein profile.

  9. 9
    salmon

    Real fish meat. Natural source of omega-3s, which kibble usually has to add back from oil.

    Position 9: supporting protein. Modest contribution to total protein weight.

  10. 10
    natural flavor

    Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.

  11. 11
    miscanthus grass

    Perennial grass used as a fiber source. Replaces cellulose in some recipes. Functional but unremarkable.

    Position 11: trace fiber inclusion.

  12. 12
    dried yeast

    Natural source of B vitamins and trace minerals. Adds a savory flavor that dogs respond well to.

  13. 13
    chicken hearts and livers

    Position 13. Small organ inclusion. Functional but not a primary contributor to the protein profile.

  14. 14
    salmon oil

    Pure omega-3s. The thing skin-and-coat formulas are usually built around.

    Position 14. Trace marine oil. Contributes some omega-3 but well below the level that drives EPA/DHA totals.

  15. 15
    tapioca starch

    Refined cassava starch, used as a binder. Easy to digest, low on nutrition.

  16. 16
    potassium chloride

    Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.

  17. 17
    salt

    Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.

  18. 18
    choline chloride

    Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.

  19. 19
    zinc amino acid complex

    Zinc bound to amino acids for better absorption. Same idea as zinc proteinate, the premium form of the mineral.

  20. 20
    iron amino acid complex

    Iron bound to amino acids for better absorption. Premium form versus inorganic iron sulfate.

  21. 21
    sodium selenite Flagged

    Inorganic selenium. Effective at AAFCO levels, no documented safety concern in dogs despite what some pet food blogs claim. Selenium yeast is a marginal upgrade, not a necessity. See why →

  22. 22
    manganese amino acid complex

    Manganese bound to amino acids for better absorption. The chelated form most premium brands use.

  23. 23
    copper amino acid complex

    Copper bound to amino acids for better absorption. Premium form versus copper sulfate.

  24. 24
    calcium iodate

    Source of iodine for thyroid function. Functional, required in complete formulas.

  25. 25
    dl-methionine

    Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.

Showing first 25 of 28. Position 1-5 has the largest weight in the recipe.
