But is it worth adding into your rotation? See what we thought from our examination of the Turkey and Sweet Potato recipe.

Nature's Domain Dog Food Review



Protein content




Taste 4/5

Dogs seem to love this kibble, and even picky eaters tend to finish their plate. On the flip side, there is no “small breed” option, meaning the actual kibble size is medium-to-big. If you have a medium dog (or larger) this shouldn’t be an issue.

As with other kibble, the flavouring agents are undisclosed. We’re giving this brand 4 out 5, mainly because of the limited size kibble for smaller dogs.

Ingredients 4/5

This dog food brand is made by Diamond Pet Foods, the same manufacturer behind Taste of the Wild. In Australia, we were only able to find the Turkey and Sweet Potato recipe, so we will focus on that for our review, although in the past a Salmon and Sweet Potato option was available.

This recipe starts well: turkey meal is the first ingredient. It’s followed by sweet potatoes, peas and potatoes. However, it’s important to note that for most processed dog foods the first two to five ingredients are roughly in the same proportion and their order is generally placed at the manufacturer’s discretion.

Looking at the first four ingredients, this is a potato-heavy food. However, the nutritional analysis looks fairly ok for a traditional kibble: 24% minimum crude protein, 14% minimum crude fat and 4% maximum crude fibre. This is above the minimum AAFCO requirements AAFCO (18% crude protein), although the overall carbohydrate content seems slightly high. This is a common issue with traditional kibble, which needs starch for the manufacturing process.

The best feature in this ingredient list is the add-ons: the vitamins, minerals, and other additives are itemised and high quality, which vastly improves the overall quality of the food. We will go over them in the following sections.

We’re taking off one star from the ingredients category because of the high quanitity of potatoes. Other than that, the overall composition is acceptable and in line with other mid-range kibble options.

Protein 4/5

As we mentioned above, the first ingredient in these recipes is turkey meal. Proteins in meal form are meats that were rendered, then powdered in order to add to pet food recipes.

The Turkey and Sweet Potato recipe features 24% minimum crude protein. This falls in line with AAFCO recommendations for adult dogs, although it is on the low side for highly active dogs. Recent studies have shown that working dogs need around 26% minimum protein [1] and even senior dogs did better with increased protein intake [2]. If you’re feeding an active dog, we recommend adding a high protein topping.

PRO TIP: Using boiled muscle meat, raw innards or even canned fish like sardines or tuna are easy add-ons to bump up the protein.

We’re taking one star off because the protein-to-carbohydrate ratio is skewed towards carbs. This is normal with traditional mid-range kibble, but it has less protein content than we’d recommend for active dogs.

Additives 5/5

This is where Nature’s Domain shines. This is a reasonably affordable food, but the manufacturers have added nice extras:

  • Fruits and vegetables: The recipe we reviewed has tomato pomace, blueberries, raspberries and other fruits. These extras seem to be moderate additions (since they appear after taurine and methionine) and do not make up the bulk of the food. However, the veggies will round up the micronutrient profile of the food and add some extra fibre.
  • Chelated minerals and vitamins: Unlike most dog kibble at this price point, all the minerals in this food are chelated. This means they have gone through a specific process that makes them easier to absorb. Because chelated minerals are more expensive than regular powdered minerals, most manufacturers don’t use it. Chelated minerals tend to signal a high quality ingredient list, and ensure proper nutrient absorption.
  • Prebiotics: Our team appreciated the addition of dried probiotics cultures and ferments. Although these cultures are killed off in the cooking process, their addition serves as food for the good microbes in your dog’s gut. Inclusion of pre and probiotics are generally a sign of a high quality food.

The additives in this food are simple but effective, particularly the use of prebiotics and chelated minerals. Most foods at this price point lack in this department, so we’re giving this food 5 out of 5 in this category.

Variety 2/5

Although this dog food has several recipes available at other Costco’s worldwide, we’re more limited with the selection in Australia. As of the time of writing, Costco Australia only lists one recipe up for sale (Turkey meal and Sweet Potato), without any other option.

If your dog doesn’t particularly like turkey, or you would like to vary the proteins, this food is not for you. Due to the lack of choice, especially considering there are other options available in other countries, we’re giving Nature’s Domain 2 out of 5 in this category.

Price 5/5

As expected for Costco, this kibble is fairly affordable. The company manages to accomplish this by selling the food in large bags exclusively and keeping the ingredient list relatively simple, save from the probiotics and chelated minerals.

We would place this brand firmly in the upper mid-range category, with a price that beats many of its direct competitors. We’re giving Nature’s Domain 5 out of 5 in this category.

Do not buy if…

This kibble is affordable and can be a great choice for many dogs, but you should keep looking if you:

  • Want to prioritise local foods: This dog food is made in the US, then shipped to Australia so its carbon footprint is high. Choosing locally-made dog food is a more sustainable option.
  • Would prefer raw or freeze dried food: Nature’s Domain only offers traditional kibble, meaning the food is cooked twice before being packaged.
  • Are looking for food with live probiotic cultures: Since this food is fully cooked, all probiotics added are killed. These cultures still serve as food for your dog’s gut microbiome, but won’t repopulate the good bacteria.

My Final Verdict

As a whole, Nature’s Domain is a great option if you’re looking for a budget dog food for adult dogs. Even though it has some shortcomings (slightly lower in proteins than other options, and heavy on potatoes), however the great additives make up for it.

This is a good option to add into your rotation, particularly if you also feed raw or freeze dried food the rest of the time.
