Ingredients Analysis
The primary protein source is turkey, followed by turkey meal, which is a concentrated source of protein. Sweet potatoes and potatoes provide gluten-free complex carbohydrates, along with dietary fiber and beta carotene. Peas contribute carbohydrates and fiber, but their protein content needs to be considered when assessing the overall meat protein percentage.
Canola oil is present, which can be a source of omega-3 fatty acids, though less biologically available than fish oil. Dried yeast is included; while some believe it offers benefits like flea repulsion and immune support, others associate it with allergies or bloat risk. Generally, unless a dog has a specific yeast allergy, it’s considered a nutritious addition.
Flaxseed is a good plant-based source of omega-3 fatty acids and fiber. Salmon oil is a valuable addition, providing highly bioavailable EPA and DHA omega-3 fatty acids.
The ingredient list also includes chicory root, a source of inulin and a prebiotic that supports digestive health. However, the presence of sodium selenite, a controversial form of selenium, is noted as a potential concern compared to more natural selenium sources. The inclusion of dried fermentation products and chelated minerals are positive aspects, aiding digestion and improving mineral absorption, respectively.
Nutrient Analysis
Based on its ingredient profile, Kirkland Signature Nature’s Domain Dog Food appears to be an above-average dry product. The estimated dry matter nutrient content shows adequate protein and fat levels, with carbohydrates making up a significant portion of the remaining content. When compared to other dry dog foods, the protein and fat levels are near average, with a carbohydrate content also in the typical range. Even accounting for the protein from peas and flaxseed, the profile suggests a substantial amount of meat in the formulation. The fat-to-protein ratio is also within a common range for dry dog foods.
