| Method | Protein | Fat | Carbs |

The first ingredient in this dog food is salmon. Although it is rich in omega-3 fatty acids, raw salmon 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 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 fourth 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 fifth 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 sixth ingredient is whitefish meal, another protein-rich meat concentrate.
The seventh 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.
After the natural flavor, we find coconut oil, 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.
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 five notable exceptions…
First, flaxseed oil is one of the best non-fish sources of omega-3 fatty acids — essential to a dog’s health.
Next, we note the inclusion of inulin, a starch-like compound made up of repeating units of carbohydrates and typically sourced from chicory root.
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, we find alfalfa, a flowering member of the pea family. Although alfalfa is high in protein (18%) and fiber, it’s uncommon to see it used in a dog food. This hay-family ingredient is more commonly associated with horse feeds.
Next, 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.
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.

The Bottom Line
Judging by its ingredients alone, Merrick Lil’ Plates Grain Free 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 38%, a fat level of 16% and estimated carbohydrates of about 38%.
As a group, the brand features an average protein content of 38% and a mean fat level of 17%. Together, these figures suggest a carbohydrate content of 38% for the overall product line.
And a fat-to-protein ratio of about 44%.
Above-average protein. Near-average fat. And below-average carbs when compared to a typical dry dog food.
Even when you consider the protein-boosting effect of the peas, potato protein and alfalfa, this looks like the profile of a kibble containing a significant amount of meat.
Bottom line?
Merrick Lil’ Plates Grain Free is a plant-based dry dog food using a significant amount of named meats as its main sources of animal protein, thus earning the brand 5 stars.
Enthusiastically 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.
