Graded by The Sniff System

In plain English

Merrick Backcountry Raw Infused Grain-Free Chicken-Free Pacific Catch Recipe is a dry food with salmon and whitefish as its primary protein sources.

This recipe has a strong protein profile, with salmon as the first ingredient, which means good biological value for your dog. It also uses quality fat sources, like pork fat and sunflower oil, and pairs fresh salmon with salmon meal, which is a good sign for how the food is made.

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

Good fit for active large sporting breeds like Golden Retrievers, Labrador Retrievers, and Irish Setters navigating diet-associated DCM concerns. Working in its favor: taurine listed as added ingredient. Salmon anchors position 1, with 2 pulse-family ingredients in the top 15 (peas at position 6, pea protein at position 7). 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) .

Looking at this for adult Golden Retrievers or Golden Retrievers with diet-associated DCM concerns ? We are building dedicated pages for these combinations.

Why this score

Solid grade. 74/100 (B) reflects the structural fit of this formula against The Sniff System's eight scoring components. Protein quality did the heavy lifting (+25 points): Strong protein profile with salmon 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 salmon as the primary ingredient, delivering high biological value.

PQI

Quality fat sources: named fat with declared fat sources.

FQI

Named fresh meat paired with same-species meal, a strong extrusion architecture.

Ingredients

Read why each ingredient is good or bad for dogs.

26 total
Good Neutral Watch Flagged
  1. 1
    salmon

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

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

  2. 2
    salmon meal

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

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

  3. 3
    whitefish meal

    Whitefish cooked into a dry concentrate. Strong protein source, common in premium formulas.

    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
    whitefish

    Real fish meat. Lean protein with a clean amino acid profile.

    Position 10: supporting protein. Modest contribution to total protein weight.

  11. 11
    sunflower oil

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

    Position 11: trace fat. Below the level that materially shifts the fat profile.

  12. 12
    flaxseed

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

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

  13. 13
    dried yeast

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

  14. 14
    tapioca

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

  15. 15
    potassium chloride

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

  16. 16
    salt

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

  17. 17
    choline chloride

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

  18. 18
    zinc amino acid complex

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

  19. 19
    iron amino acid complex

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

  20. 20
    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 →

  21. 21
    manganese amino acid complex

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

  22. 22
    copper amino acid complex

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

  23. 23
    calcium iodate

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

  24. 24
    dl-methionine

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

  25. 25
    taurine

    Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
