Recipe and Label Analysis

We have selected Nature’s Domain Turkey and Sweet Potato for a detailed recipe and nutrient analysis.

The label and nutrient data provided here are calculated based on a dry matter basis.

Ingredient Analysis

The primary ingredient in this dog food is turkey meal, which is a concentrated source of protein, containing nearly 300% more protein than fresh turkey.

Sweet potatoes are the second ingredient and serve as a gluten-free source of complex carbohydrates, dietary fiber, and beta carotene.

Peas, the third ingredient, are quality carbohydrates and rich in natural fiber as is common for legumes.

It’s worth noting that peas have a protein content of about 25%, which affects the meat content assessment of this dog food.

Potatoes, the fourth ingredient, provide gluten-free digestible carbohydrates but offer only modest nutritional value for dogs, except for their caloric content.

Canola oil, the fifth ingredient, can be a controversial ingredient due to its potential derivation from genetically modified rapeseed. However, it is also a source of essential omega-3 fatty acids.

Tomato pomace, the sixth ingredient, is a fiber and nutrient-rich by-product obtained after processing tomatoes into various products. It has both its advocates and detractors in the pet food industry.

Flaxseed, the seventh ingredient, is an excellent plant source of healthy omega-3 fatty acids and soluble fiber.

Salmon oil, found after the natural flavor, is a rich source of EPA and DHA omega-3 fatty acids, which are highly beneficial for both dogs and humans.

While there are other ingredients further down the list, they are unlikely to have a significant impact on the overall rating of this Kirkland product, except for nutritional supplements.

There are three notable exceptions:

  1. Chicory root, rich in inulin, serves as a natural source of soluble dietary fiber and a prebiotic to support the growth of healthy bacteria in a dog’s digestive tract.

  2. Sodium selenite, a controversial form of selenium, is considered nutritionally inferior to the more natural selenium yeast.

  3. Chelated minerals, which are chemically attached to protein for better absorption, are typically found in higher-quality dog foods.

Nutrient Analysis

Kirkland Signature Nature’s Domain Dog Food appears to be an above-average dry product based on its ingredients alone.

It offers a dry matter protein reading of 27%, a fat level of 16%, and estimated carbohydrates of about 50%.

Compared to other dry dog foods, this brand has an average protein content of 27%, a mean fat level of 16%, and a carbohydrate content of 49%, resulting in a fat-to-protein ratio of approximately 58%.

Considering the protein-boosting effect of peas and flaxseed in this recipe, as well as the legumes found in other recipes, this dry dog food contains a notable amount of meat.
