In plain English

Nature's Logic 100% Natural Canine Lamb Meal Feast is a dry food for all life stages, with lamb meal as its primary protein.

This formula uses quality carbohydrate sources that provide fermentable fiber. It also includes diverse protein sources like spray dried pork liver and fish meal, which offer a broader range of amino acids.

The main thing to watch is the protein quality, as lamb meal as the primary protein source might offer limited bioavailable amino acids.

Good fit for dogs of all ages. Less ideal if you're looking for a food with higher protein bioavailability from its primary source.

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

Who this is for

The landmark 14-year Purina Lifespan Study on 48 Labrador Retrievers demonstrated that dogs fed 25% fewer calories lived a median of 1.8 years longer and delayed the onset of chronic diseases. Good fit for active large sporting breeds like Labrador Retrievers, Golden Retrievers, and English Setters navigating weight management. At 394 kcal/cup this formula runs on the moderate side, with crude fiber at 5% (above the catalog median, supports satiety). The 2014 AAHA Weight Management Guidelines define overweight as a Body Condition Score (BCS) of 6-7 on a 9-point scale. A score of 8 or 9 indicates obesity, representing 20-30% and >30% above ideal body weight, respectively  (Brooks et al., 2014) .

Ingredients

34 total
Good Neutral Watch Flagged
  1. 1
    lamb meal

    Lamb cooked down to a dry concentrate. Per pound, more protein than fresh lamb. See why →

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

  2. 2
    millet

    Gluten-free whole grain. Fine for most dogs, often used as an alternative to rice.

    Position 2: major carbohydrate source.

  3. 3
    chicken fat

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

    Position 3: primary fat source. Drives the formula's caloric density and omega-6 content.

  4. 4
    yeast culture

    Fermented yeast. Source of B vitamins and beta-glucans that some research suggests support immune function.

  5. 5
    pumpkin seed flour
  6. 6
    spray dried pork liver
  7. 7
    alfalfa nutrient concentrate

    Concentrated alfalfa, rich in vitamins, minerals, and fiber. A legitimate functional ingredient.

  8. 8
    montmorillonite clay

    Natural clay used as a binder and anti-caking agent. Functional, not nutritional.

  9. 9
    spray dried porcine plasma
  10. 10
    dried kelp

    Natural source of iodine and trace minerals. A common premium-brand inclusion.

  11. 11
    fish meal

    Concentrated fish protein, usually whitefish, herring, or mackerel. Strong amino acid profile. See why →

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

  12. 12
    dried tomato
  13. 13
    almonds
  14. 14
    dried chicory root

    Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.

    Position 14: trace fiber inclusion.

  15. 15
    dried apple

    Whole apple with the moisture removed. Real fruit, fiber, modest nutrition contribution.

  16. 16
    dried carrot

    Real vegetable. Fiber, beta-carotene, antioxidants. Same as carrots, sometimes singular on labels.

  17. 17
    pumpkin

    Soluble fiber that supports stool quality. Mild and well-tolerated.

  18. 18
    dried apricot
  19. 19
    dried blueberry
  20. 20
    dried spinach

    Leafy green. Some iron, vitamin K, and fiber. The dose in kibble is small but it's real food.

  21. 21
    dried broccoli

    Real vegetable. Adds fiber and some antioxidants. Fine in the small amounts used in kibble.

  22. 22
    parsley

    Real herb. Trace amount of vitamins K and C. The dose in kibble is small, mostly there for label appeal.

  23. 23
    dried cranberry

    Same as cranberries. Real ingredient, dose in kibble is small.

  24. 24
    dried artichoke
  25. 25
    rosemary

Showing first 25 of 34. Position 1-5 has the largest weight in the recipe.
