Graded by The Sniff System

In plain English

Merrick Backcountry Raw Infused Grain-Free Great Plains Red Recipe Freeze-Dried Dog Food is a freeze-dried food featuring beef and salmon.

Beef is the first ingredient, giving it a strong protein profile with high biological value. You'll also find quality fat sources, like pork fat and sunflower oil, and diverse proteins such as salmon meal and lamb.

Nothing concerning in the deck.

Good fit for adult dogs of any size. 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 adult Golden Retrievers and similar active sporting breeds navigating diet-associated DCM concerns. Beef anchors position 1, with 2 pulse-family ingredients in the top 15 (peas at position 6, pea protein at position 7), plus beef liver at position 13 (a natural taurine precursor) and salmon meal at position 3. In its 2022 update on diet-associated DCM, the FDA identified Golden Retrievers as the most reported breed, with 121 cases out of 1,382 total canine reports (8.8%) received between January 1, 2014, and November 1, 2022  (FDA, 2022) .

Why this score

Solid grade. 71/100 (B) reflects the structural fit of this formula against The Sniff System's eight scoring components. Protein quality did the heavy lifting (+22 points): Strong protein profile with beef as the primary ingredient, delivering high biological value. The supporting beat: fat quality (+11 points). Quality fat sources: named fat with declared fat sources. What's keeping it out of A-tier: carbohydrate quality (8 of 16 possible). Full carbohydrate quality requires whole-grain or single-source carbohydrates with a declared fermentable fiber.

What lifted the score

Strong protein profile with beef as the primary ingredient, delivering high biological value.

PQI

Quality fat sources: named fat with declared fat sources.

FQI

Includes egg, named fish, or organ meat for diverse high-bioavailability protein.

Ingredients

28 total
Good Neutral Watch Flagged
  1. 1
    beef

    Real meat. Dense in protein and iron. Some dogs are sensitive to it, but for most it's an excellent base.

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

  2. 2
    pork and bone meal

    Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.

  3. 3
    salmon meal

    Salmon cooked into a dry concentrate. Carries both protein and natural omega-3s in one ingredient. See why →

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

  4. 4
    sweet potato

    Complex carb with fiber and beta-carotene. Gentle on the stomach.

    Position 4: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.

  5. 5
    potato

    Standard white potato. Steady carb source, common starch in grain-free recipes.

    Position 5: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.

  6. 6
    peas

    Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →

    Position 6. Moderate inclusion. Contributes carbohydrate and some plant protein.

  7. 7
    pea protein

    Concentrated plant protein. Inflates the protein number on the label without matching the amino acid quality of meat.

    Position 7. Moderate inclusion. Contributes carbohydrate and some plant protein.

  8. 8
    natural flavor

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

  9. 9
    pork fat

    Real animal fat from a named species. Clean energy source.

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

  10. 10
    potato protein

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

    Position 10: moderate plant-protein boost. Less likely to materially shift the protein profile.

  11. 11
    lamb

    Real meat. Often used for dogs with chicken or beef sensitivities. Slightly higher fat content than chicken.

    Position 11: trace protein. Likely there for amino-acid diversity or label appeal more than nutritional weight.

  12. 12
    sunflower oil

    Common plant oil. Useful in moderation for omega-6, though too much skews the omega ratio against the dog's favor.

    Position 12: trace fat. Below the level that materially shifts the fat profile.

  13. 13
    beef liver

    Organ meat. Among the most nutrient-dense ingredients available, rich in B vitamins, iron, and vitamin A.

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

  14. 14
    flaxseed

    Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.

    Position 14: trace fat. Below the level that materially shifts the fat profile.

  15. 15
    tapioca

    Starch from cassava root. Highly digestible energy source, but pure starch with minimal nutrition beyond that.

  16. 16
    dried yeast

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

  17. 17
    potassium chloride

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

  18. 18
    salt

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

  19. 19
    choline chloride

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

  20. 20
    zinc amino acid complex

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

  21. 21
    iron amino acid complex

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

  22. 22
    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 →

  23. 23
    manganese amino acid complex

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

  24. 24
    copper amino acid complex

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

  25. 25
    calcium iodate

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