The first ingredient in this dog food is bison. Although it is a quality item, raw bison contains up to 73% water. After cooking, most of that moisture is lost, reducing the meat content to just a fraction of its original weight.

After processing, this item would probably account for a smaller part of the total content of the finished product.

The second ingredient is salmon meal. Because it is considered a meat concentrate, fish meal contains almost 300% more protein than fresh fish itself.

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

The third ingredient includes garbanzo beans, also known as chickpeas. Like peas, bean and lentils, the chickpea is a nutritious member of the fiber-rich legume (pulse) family of vegetables.

Garbanzos contain about 22% protein, something which must be considered when evaluating the total protein reported in this food.

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

The fifth ingredient includes lentils. Lentils are a quality source of carbohydrates. Plus (like all legumes) they’re rich in natural fiber.

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

The sixth ingredient is pea flour, a powder made from roasted yellow peas. Pea flour contains as much as 25% protein, a factor that must be considered when judging the meat content of this dog food.

It’s important to note that a number of ingredients included in this recipe are each a type of legumes:

  • Garbanzo beans
  • Peas
  • Lentils
  • Pea flour

Although they’re a mixture of quality plant ingredients, there’s an important issue to consider here. And that’s the recipe design practice known as ingredient splitting.

If we were to combine all these individual items together and report them as one, that newer combination would likely occupy a significantly higher position on the list.

In addition, legumes contain about 25% protein, a factor that must also be considered when judging the meat content of this dog food.

The seventh ingredient is sunflower oil. Sunflower oil is nutritionally similar to safflower oil. Since these oils are high in omega-6 fatty acids and contain no omega-3’s, they’re considered less nutritious than canola or flaxseed oils.

Sunflower oil is notable for its resistance to heat damage during cooking.

There are several different types of sunflower oil, some better than others. Without knowing more, it’s impossible to judge the quality of this ingredient.

The eighth ingredient is tapioca, a gluten-free, starchy carbohydrate extract made from the root of the cassava plant.

The ninth 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.

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 four notable exceptions

First, 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.

Next, this recipe includes chicory root. Chicory 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.

In addition, coconut oil is a natural oil rich in medium-chain fatty acids.

Medium-chain triglycerides have been shown to improve cognitive function in older dogs.2

Because of its proven safety3 as well as its potential to help in the treatment of canine cognitive dysfunction syndrome (CDS) and chronic skin disorders, MCT can be considered a positive addition to this recipe.

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.

Artemis Osopure Grain Free
Limited Ingredient Formula Dog Food
The Bottom Line

Judging by its ingredients alone, Artemis Osopure Grain Free Limited Ingredient Formula Dog Food looks like an above-average dry product.

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 16%. Together, these figures suggest a carbohydrate content of 50% for the overall product line.

And a fat-to-protein ratio of about 58%.

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 garbanzo beans, peas, lentils, pea flour and flaxseed, this looks like the profile of a kibble containing a moderate amount of meat.

Bottom line?

Artemis Osopure Grain Free Limited Ingredient Formula is a plant-based dry dog food using a moderate amount of named meat meals 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.
