Kirkland Signature Nature’s Domain offers a compelling option for pet owners seeking a balance of quality ingredients and affordability. Produced by Diamond Pet Foods, the same reputable company behind the well-regarded Taste of the Wild brand, this Kirkland offering brings a high standard to the CostCo “home brand” market. This review delves into the ingredients, nutritional analysis, and overall value proposition of Kirkland Signature Nature’s Domain, particularly its salmon formula.
Ingredient Analysis

The inclusion of dried salmon meal as the second ingredient further reinforces this commitment.
