Ingredient Analysis

The first ingredient in this dog food is turkey meal. Turkey meal is considered a meat concentrate and contains nearly 300% more protein than fresh turkey.

The second ingredient is sweet potato. Sweet potatoes are a gluten-free source of complex carbohydrates in a dog food. They are naturally rich in dietary fiber and beta carotene.

The third ingredient includes peas. Peas are a quality source of carbohydrates. And like all legumes, they’re rich in natural fiber.

However, peas contain about 25% protein, a factor that must be considered when judging the meat content of this dog food.

The fourth ingredient is potato. Potatoes can be considered a gluten-free source of digestible carbohydrates. Yet with the exception of perhaps their caloric content, potatoes are of only modest nutritional value to a dog.

The fifth ingredient is canola oil. Unfortunately, canola can be a controversial item. That’s because it can sometimes (but not always) be derived from genetically modified rapeseed.

Yet others cite the fact that canola oil can be a significant source of essential omega-3 fatty acids.

In any case, plant-based oils like canola are less biologically available to a dog than fish oil as a source of quality omega-3 fats.

The sixth ingredient is tomato pomace. Tomato pomace is a controversial ingredient, a by-product remaining after processing tomatoes into juice, soup and ketchup.

Many praise tomato pomace for its high fiber and nutrient content, while others scorn it as an inexpensive pet food filler.

Just the same, there’s probably not enough tomato pomace here to make much of a difference.

The seventh ingredient is flaxseed, one of the best plant sources of healthy omega-3 fatty acids. Provided they’ve first been ground into a meal, flax seeds are also rich in soluble fiber.

However, flaxseed contains about 19% protein, a factor that must be considered when judging the actual meat content of this dog food.

After the natural flavor, we find salmon oil. Salmon oil is naturally rich in the prized EPA and DHA type of omega-3 fatty acids. These two high quality fats boast the highest bio-availability to dogs and humans.

Depending on its level of freshness and purity, salmon oil should be considered a commendable addition.

From here, the list goes on to include a number of other items.

But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of this Kirkland product.

With 2 notable exceptions

First, chicory root is rich in inulin, a starch-like compound made up of repeating units of carbohydrates and found in certain roots and tubers.

Not only is inulin a natural source of soluble dietary fiber, it’s also a prebiotic used to promote the growth of healthy bacteria in a dog’s digestive tract.

And lastly, this food contains chelated minerals, minerals that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better dog foods.

Nutrient Analysis

Based on its ingredients alone, Kirkland Signature Nature’s Domain Dog Food looks like an above-average dry product.

The dashboard displays a dry matter protein reading of 27%, a fat level of 16% and estimated carbohydrates of about 50%.

As a group, the brand features an average protein content of 27% and a mean fat level of 15%. Together, these figures suggest a carbohydrate content of 50% for the overall product line.

And a fat-to-protein ratio of about 57%.

Above-average protein. Near-average fat. And near-average carbs when compared to a typical dry dog food.

Even when you consider the protein-boosting effect of the peas and flaxseed, this still looks like the profile of a dry dog food containing a notable amount of meat.

Is Nature’s Domain a Good Dog Food?

Kirkland Signature Nature’s Domain is a grain-free dry dog food using a notable amount of named meat meals as its dominant source of animal protein, thus earning the brand 4.5 stars.

Highly recommended.
