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 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 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 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 seventh ingredient is lamb meal, another protein-rich meat concentrate.
After the natural flavor, we find pea protein, what remains of a pea after removing the starchy part of the vegetable.
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 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 five notable exceptions…
First, we find quinoa. Quinoa (pronounced keen-wah) is not a true cereal grain but a plant prized for its gluten-free seeds.
Compared to most other grain-type ingredients, it is high in protein (about 12-18%), dietary fiber and other healthy nutrients.
Next, we find alfalfa meal. Although alfalfa meal is high in plant protein (about 18%) and fiber (25%), this hay-family item is more commonly associated with horse feeds.
In addition, chia seed is an edible seed nutritionally similar to flax or sesame. Provided they’re first ground into a meal, chia seeds are rich in both omega-3 fatty acids as well as dietary fiber.
However, chia seeds contain about 17% protein, a factor that must be considered when judging the meat content of this dog food.
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.
Merrick Classic Dog Food
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 17%. Together, these figures suggest a carbohydrate content of 43% for the overall product line.
And a fat-to-protein ratio of about 52%.
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 peas, pea protein, quinoa, alfalfa and chia seed, 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 chicken, pork or lamb meals as its main sources of animal protein, thus earning the brand 4.5 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.
