The first ingredient in this dog food is chicken. Although it is a quality item, raw chicken 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 chicken meal. Chicken meal is considered a meat concentrate and contains nearly 300% more protein than fresh chicken.
The third ingredient includes garbanzo beans, also known as chickpeas. Like peas, bean and lentils, the chickpea is a nutritious member of the fiber-rich legume (pulse) family of vegetables.
Garbanzos contain about 22% protein, something which must be considered when evaluating the total protein reported in this food.
The fourth ingredient includes peas. Peas are a quality source of carbohydrates. And like all legumes, they’re rich in natural fiber.
The fifth ingredient is pea flour, a powder made from roasted yellow peas.
However, both peas and pea flour contain about 25% protein, a factor that must be considered when judging the meat content of this dog food.
The sixth ingredient is tomato pomace. Tomato pomace is a controversial ingredient, a by-product remaining after processing tomatoes into juice, soup and ketchup.
Many praise tomato pomace for its high fiber and nutrient content, while others scorn it as an inexpensive pet food filler.
Just the same, there’s probably not enough tomato pomace here to make much of a difference.
The seventh ingredient is chicken fat. Chicken fat is obtained from rendering chicken, a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.
Chicken fat is high in linoleic acid, an omega-6 fatty acid essential for life. Although it doesn’t sound very appetizing, chicken fat is actually a quality ingredient.
The eighth 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 ninth 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.
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, this recipe includes quinoa seed. 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.
So, one must weigh the potential benefits of feeding garlic against its proven tendency to cause subclinical damage to the red blood cells of the animal.
In addition, 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 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.

The Bottom Line
Judging by its ingredients alone, Pinnacle Grain Free 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 29% and a mean fat level of 16%. Together, these figures suggest a carbohydrate content of 47% for the overall product line.
And a fat-to-protein ratio of about 52%.
Near-average protein. Near-average fat. And near-average carbs when compared to a typical dry dog food.
When you consider the protein-boosting effect of the garbanzo beans, pea products, flaxseed and quinoa, this looks like the profile of a kibble containing a moderate amount of meat.
Pinnacle Grain Free is a plant-based dry dog food using a moderate amount of various species as its main sources of animal protein, thus earning the brand 4 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.
