The first ingredient in this dog food is beef. Although it’s a quality item, raw beef contains about 80% 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 pork meal. Pork meal is considered a meat concentrate and contains nearly 300% more protein than fresh pork.
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 salmon 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
The fifth ingredient is barley. Barley is a starchy carbohydrate supplying fiber and other healthy nutrients. However, aside from its energy content, this cereal grain is of only modest nutritional value to a dog.
The sixth ingredient is brown rice, a complex carbohydrate that (once cooked) can be fairly easy to digest. However, aside from its natural energy content, rice is of only modest nutritional value to a dog.
The seventh 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 eighth ingredient is pork fat, a product from rendering pig meat.
Commonly known as lard, pork fat can add significant flavor to any dog food. And it can be high in linoleic acid, an omega-6 fatty acid essential for life.
Although it may not sound very appetizing, pork fat (in moderate amounts) is actually an acceptable pet food ingredient.
The ninth ingredient includes oats. Oats are rich in B-vitamins, minerals and dietary fiber.
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, we find flaxseed oil, one of the best non-fish sources of omega-3 fatty acids — essential to a dog’s health.
Next, 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.
In addition, 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.
Next, we note the inclusion of dried fermentation products in this recipe. Fermentation products are typically added to provide enzymes to aid the animal 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.

The Bottom Line
Judging by its ingredients alone, Merrick Classic 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 16%. Together, these figures suggest a carbohydrate content of 44% for the overall product line.
And a fat-to-protein ratio of about 49%.
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 and alfalfa, this looks like the profile of a kibble containing a notable amount of meat.
Merrick Classic is a plant-based kibble using a notable amount of poultry, pork or lamb meals as its main sources of animal protein, thus earning the brand 5 stars.
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.
