Expert Summary

Feed Wise rates this below the standard we look for in this category for Kirkland Signature Nature's Domain Salmon and Sweet Potato Formula Dog Food, a dry kibble formula led by salmon and fish meal. The manufacturer publishes an AAFCO nutritional adequacy statement, so it can be fed as a complete daily diet for growth and puppy feeding. Supporting the rating, it is manufactured in United States and the label declares 27% crude protein.

Animal Protein Quality

11.6 / 25

This is the largest single category in FeedWise. It looks at which animal ingredients are present, whether the species is named, whether organs, egg and named fats are included, and whether concentrated plant proteins are diluting the animal content.

  • Named animal protein first

    Salmon is a named animal ingredient in position 1.

    +8 / 8
  • Animal Prominence Index

    Animal Prominence Index 41 of 100. This is a FeedWise position-weighted measure of how far animal ingredients dominate the ingredient panel. It is a label-position index, not a manufacturer-disclosed recipe percentage.

    +1.2 / 5
  • Liver

    No liver in the ingredient panel.

    0 / 2
  • Heart

    No heart in the ingredient panel.

    0 / 2
  • Other appropriate organs

    No additional organ meats identified.

    0 / 2
  • Whole egg

    No meaningful egg inclusion.

    0 / 1
  • Named animal or marine fats

    Named animal or marine fat sources: Salmon, salmon oil (a source of DHA).

    +1 / 2
  • Verified animal ingredient proportion

    The manufacturer has not published an animal ingredient percentage. Excluded from the score rather than counted against the product.

    NOT SCORED

Ingredient Quality

10.7 / 20

Every ingredient is classified into a quality tier and weighted by its position on the label, so ingredient number one counts far more than ingredient number fifteen.

  • Position weighted ingredient quality

    14 food ingredients assessed by quality tier with early positions weighted most heavily. 36 fortifying nutrients or preservatives excluded from the average.

    +13.7 / 20
  • Vague animal ingredients

    Animal ingredients without an identified species: fish meal.

    -2
  • Ingredient splitting

    Multiple fractions of the same core ingredient appear: PEA FAMILY (peas, pea flour).

    -1

Carbohydrate and Plant Load

0 / 15
  • Estimated carbohydrate: not calculable
  • Pulse ingredients detected: peas, pea flour
  • Plant protein concentrates: none
  • Ingredient splitting: PEA FAMILY (peas, pea flour)

Carbohydrate is not calculable because ash is not disclosed. It is left blank rather than overstated.

  • Carbohydrate burden

    Carbohydrate is not precisely calculable because ash has not been disclosed. This is an evidence limitation, not evidence of high carbohydrate, so it is removed from the score and reported as reduced confidence.

    NOT SCORED
  • Ingredient based plant load

    Plant load assessed as VERY HIGH. Carbohydrate bearing plant ingredients: sweet potatoes (starchy vegetable), potatoes (starchy vegetable), peas (whole pulse), pea flour (refined starch), dried beet pulp (fibre ingredient), dried chicory root (fibre ingredient).

    0 / 8
  • Split plant fractions

    Split plant fractions understate the true plant load in the ingredient order.

    -1

How is it made?
