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 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 potato protein, the dry residue remaining after removing the starchy part of a potato.

Even though it contains over 80% protein, this ingredient would be expected to have a lower biological value than meat.

And less costly plant-based products like this can notably boost the total protein reported on the label — a factor that must be considered when judging the actual meat content of this dog food.

The seventh ingredient is potato fiber, a source of dietary fiber. Fiber in reasonable amounts can help stabilize blood sugar levels and reduce a dog food’s caloric content.

After the natural flavor, we find 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.

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 product.

With three notable exceptions

First, we note the use of ocean fish meal, another protein-rich meat concentrate.

Fish meal is typically obtained from the “clean, dried, ground tissue of undecomposed whole fish and fish cuttings” of commercial fish operations.1

Unfortunately, this particular item is anonymous. Because various fish contain different types of fats, we would have preferred to have known the source species.

Next, 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.

Kirkland Signature Nature’s Domain Dog Food
The Bottom Line

Judging by its ingredients alone, Kirkland Signature Nature’s Domain looks like an above-average dry dog food.

But ingredient quality by itself cannot tell the whole story. We still need to estimate the product’s meat content before determining a final rating.

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%.

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

When you consider the protein-boosting effect of the peas, potato protein and flaxseed in this recipe and the plant-based protein boosters in the others, this looks like the profile of a kibble containing just a moderate amount of meat.

Bottom line?

Kirkland Signature Nature’s Domain is a grain-free plant-based dry dog food using a moderate amount of various named species as its main sources of animal protein, thus earning the brand 3.5 stars.

Recommended.

Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content and (when appropriate) their fat-to-protein ratios.

    Hi, take the Kirkland back to shop, get a refund or contact the makers, send them a copy of your vet bill & see if you can be reimburse….
    Where do you store your dry kibble???
    Before the kibble leaves the warehouse batches are tested then it all depends on how the dry kibble is transported, where it’s stored at warehouse etc this can cause the kibble to go off…. I always make sure where I buy my pet food from has A/C & I store the kibble in air tight containers in a dry cool spot in my house…..
    As soon as you open a bag of kibble the air/oxygen gets to the kibble, they say you have around 14 days then the oils start to go rancid, I never buy any kibbles that have salmon oil or fish oil they go off the quickest….I use my bag of kibble within 1 month of opening it…..

    I have been feeding our dogs Natures Domain for over 4 years. All of a sudden our dogs got explosive diarrhea and projectile vomiting. Or oldest dog wouldn’t walk around with his tail up anymore. Took them to the vet and nothing was wrong with them. Started them on a chicken and rice diet. That helped. Everything was fine. Slowly started to put their natures domaine dog food back into their diet…they became lathargic and having explosive diarrhea again. Thought maybe I introduced the dog food back in too soon. Back to chicken and rice for 4 more days. They were ok again. Back to adding dog food. Diarrhea. So bad they were having accidents in the house. The poor things have lost so much weight I can see their hip bones thought their fur. I read some bad reviews on Natures Domain dog food. Decided to try a different brand. After 2 days they are back to to normal. I believe this food was poisoning my dogs. Stay away.

  • Thanks for the awesome information.

    Canola oil grows in fields. Not on a tree. I live in Alberta and there are fields and fields of it.

  • Christina Lyons

    You are right on the name. And Canada and 1970 But so very wrong about the nut and tree. A simple Google of canola oil will show you. This is even on a website specifically about canola. I’m guessing you’ve never seen a canola field http://canolaeatwell.com/what-is-canola-oil/

  • soundbonz

    OMG!! Canola oil is from a tree developed in Canada – hence the name CANola – in the 1970s. I was incorrect about it being a GMO tree – it’s actually old fashioned cross breeding – but I am correct that the tree produces a nut that produces the oil.

  • Christina Lyons

    Just FYI canola oil is from a plant like rapeseed. The seeds are pressed to make canola oil. There’s no tree or nuts.

  • Kirsten Dawes

    This is the only food my 6 dogs will agree on. They eat the turkey and sweet potato version. I’ve been feeding it to my dogs for 4 years now. Every once in awhile I try to make a switch to a “5 star” food but there is always instant diarrhea and sometimes vomiting. Last time I tried Taste Of The Wild with a very gradual switch and my 2 sensitive german shepherds and bull terrier (who has a stomach made of steel usually) all had projectile diarrhea. As soon as I made the switch back to this, and quite suddenly, everyone had firm poops again and are happy and healthy dogs. My 3 pugs are 11 years old, and they’ve been on this the longest (4 years) and they have been thankfully completely healthy and their yearly blood work always come back perfect. I work at an animal hospital and to see dogs my dogs age with not a single problem on their bloodwork is rare. Never tried the beef or chicken because I’m afraid my dogs whose breeds are allergy prone will get allergies. Occasionally I will get a bag of the salmon which they do good on too. Pretty much stuck feeding this forever.

    Are you kidding? Have you ever seen a dog ingest antifreeze? People count on “instincts” way too much.
