The first ingredient in this dog food is turkey. Although it is a quality item, raw turkey 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 turkey meal. Turkey meal is considered a meat concentrate and contains nearly 300% more protein than fresh turkey.
It’s important to note that the next three ingredients included in this recipe are each a type of legume:
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 sixth 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 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.
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 two notable exceptions…
First, we find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.
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.

Dog Food Review
Judging by its ingredients alone, Merrick Limited Ingredient Diet 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.
As a group, the brand features an average protein content of 32% and a mean fat level of 17%. Together, these figures suggest a carbohydrate content of 43% for the overall product line.
And a fat-to-protein ratio of about 55%.
Above-average protein. Near-average fat. And below-average carbs when compared to a typical dry dog food.
When you consider the protein-boosting effect of the chickpeas, lentils, peas and flaxseed, this looks like the profile of a kibble containing a moderate amount of meat.
Merrick Limited Ingredient Diet is a grain-free dry dog food using a moderate amount of named meat meals as its main source of animal protein, thus earning the brand 4 stars.
However, it’s unfortunate the company chose to include so much plant-based protein in its recipe. Otherwise, we would have been compelled to award this product a higher rating.
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.
