In plain English

Purina Pro Plan Specialized Shredded Blend Lamb & Rice Formula is a dry food for small breed dogs, featuring lamb as its primary protein.

Lamb is the first ingredient, providing good protein quality and solid amino acid coverage. The formula also includes dried egg product, adding diverse, high-bioavailability protein. It has AAFCO feeding trial substantiation, which is a strong indicator of nutritional adequacy.

A key watch item is the lack of a declared omega-3 source. Ingredients like fish oil, salmon oil, or algae oil are all absent from the formula.

Good fit for small breed dogs who need a lamb-based diet. Less ideal if you prefer a food with a declared omega-3 source.

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

Who this is for

Strong fit for moderately active toy breeds, including the Cavalier King Charles Spaniel, navigating diet-associated DCM concerns. Lamb anchors position 1, with zero pulses in the top 15. The FDA's 2019 investigation update on diet-associated DCM included 13 reported cases in Cavalier King Charles Spaniels, making them one of the top 15 most frequently reported breeds at that time  (FDA, 2019) .

Looking at this for adult Cavalier King Charles Spaniels or Cavalier King Charles Spaniels with diet-associated DCM concerns ? We are building dedicated pages for these combinations.

Ingredients

29 total
Good Neutral Watch Flagged
  1. 1
    lamb

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

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

  2. 2
    corn protein meal

    Concentrated corn protein. Similar in role to corn gluten meal, pads the protein number on the label without matching meat amino acids.

    Position 2: major carbohydrate source.

  3. 3
    rice

    Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.

    Position 3: major carbohydrate source.

  4. 4
    poultry by-product meal

    Unnamed poultry. The mix can include any combination of chicken, turkey, or other birds, with no traceability. Named by-product meals are fine. This one isn't.

    Position 4: significant protein contributor. Adds amino-acid diversity to the top of the deck.

  5. 5
    soybean meal

    Concentrated soy protein. Cheap plant protein that pads the label number, common in budget formulas.

    Position 5: plant protein in the top 5. Stacked with animal protein, can inflate the crude protein number without matching the amino-acid quality of named animal sources.

  6. 6
    whole grain corn

    Whole corn with the kernel intact. Decent fiber and B vitamins, though it can crowd out meat in cheaper recipes.

    Position 6: supporting grain. Smaller contribution to the carb deck.

  7. 7
    wheat

    Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.

    Position 7: supporting grain. Smaller contribution to the carb deck.

  8. 8
    beef fat preserved with mixed-tocopherols

    Real animal fat from a named species, with natural vitamin E doing the preservation. The clean version.

    Position 8: supporting protein. Modest contribution to total protein weight.

  9. 9
    corn germ meal

    Position 9: minor grain inclusion.

  10. 10
    natural flavor

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

  11. 11
    dried egg product

    Whole eggs with the water removed. Same nutritional value as fresh eggs, just shelf-stable.

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

  12. 12
    glycerin

    Humectant used in soft-moist foods to keep them chewy. Safe in moderation but a signal of a processed semi-moist product.

  13. 13
    wheat bran

    Position 13: minor grain inclusion.

  14. 14
    calcium carbonate

    Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.

  15. 15
    mono and dicalcium phosphate

    Source of calcium and phosphorus. Standard inclusion in complete dog foods.

  16. 16
    dried yeast

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

  17. 17
    soybean oil

    Plant oil. High in omega-6, which is required but commonly oversupplied. Fine in moderation.

  18. 18
    salt

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

  19. 19
    potassium chloride

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

  20. 20
    zinc proteinate

    Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.

  21. 21
    ferrous sulfate

    Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.

  22. 22
    manganese proteinate

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

  23. 23
    copper proteinate

    Copper bound to protein for better absorption. Common in better-formulated diets.

  24. 24
    calcium iodate

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

  25. 25
    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 →
