The first ingredient in this dog food includes chicken. Chicken is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of chicken”.1
Chicken is naturally rich in the ten essential amino acids required by a dog to sustain life.
The second ingredient is chicken broth. Broths are nutritionally empty. But because they add both flavor and moisture to a dog food they are a common finding in many canned products.
The third ingredient is dried egg product, a dehydrated form of shell-free eggs. Quality can vary significantly. Lower grade egg product can even come from commercial hatcheries — from eggs that have failed to hatch.
In any case, eggs are easy to digest and have an exceptionally high biological value.
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 carrageenan, a gelatin-like thickening agent extracted from seaweed. Although carrageenan has been used as a food additive for hundreds of years, there does appear to be some recent controversy regarding its long term biological safety.
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 Grain Free looks like an above-average canned 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 44% and a mean fat level of 22%. Together, these figures suggest a carbohydrate content of 27% for the overall product line.
And a fat-to-protein ratio of about 50%
Above-average protein. Near-average fat. And near-average carbs when compared to a typical canned dog food.
Free of any plant-based protein boosters, this looks like the profile of a canned product containing a significant amount of meat.
Merrick Grain Free canned dog food is a meat-based wet product containing a significant amount of named species 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.
Rice ingredients can sometimes contain arsenic. Until the US FDA establishes safe upper levels for arsenic content, pet owners may wish to limit the total amount of rice fed in a dog's daily diet.
