The first ingredient in this dog food is trout, a freshwater species closely related to salmon. Trout is rich rich in omega-3 fatty acids but also 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 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 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 pea flour, a powder made from roasted yellow peas. Pea flour contains as much as 25% protein, a factor that must be considered when judging the meat content of this dog food.
The fifth ingredient is 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.
The sixth 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.
The seventh ingredient is chickpeas, also known as garbanzo beans. Like peas, bean and lentils, the chickpea is a nutritious member of the fiber-rich legume (or pulse) family of vegetables.
However, chickpeas contain about 22% protein, a factor that must be considered when judging the actual meat content of this dog food.
The eighth ingredient is 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.
After the natural flavor, we find salmon oil. 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.
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 four notable exceptions…
First, 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.
Next, we find beet pulp. Beet pulp is a controversial ingredient, a high fiber by-product of sugar beet processing.
Some denounce beet pulp as an inexpensive filler while others cite its outstanding intestinal health and blood sugar benefits.
We only call your attention here to the controversy and believe the inclusion of beet pulp in reasonable amounts in most dog foods is entirely acceptable.
In addition, 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 also 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.
Zignature Dog Food
The Bottom Line
Judging by its ingredients alone, Zignature 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 33% and a mean fat level of 18%. Together, these figures suggest a carbohydrate content of 41% for the overall product line.
And a fat-to-protein ratio of about 54%.
Above-average protein. Above-average fat. And below-average carbs when compared to a typical dry dog food.
When you consider the protein-boosting effect of the pea products, flaxseed, chickpeas and alfalfa meal, this looks like the profile of a kibble containing a moderate amount of meat.
Zignature is a plant-based grain free dry dog food using a moderate amount of various meat 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.
