The first ingredient in this dog food is chicken meal. Chicken meal is considered a meat concentrate and contains nearly 300% more protein than fresh chicken.
The second 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 third ingredient 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 fourth 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 fifth ingredient includes oats. Oats are rich in B-vitamins, minerals and dietary fiber.
The sixth 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 seventh ingredient is 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.
The eighth 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 ninth ingredient is dried whole egg, a dehydrated powder made from shell-free eggs. 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 six notable exceptions…
First, 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.
Next, this recipe includes dried alfalfa. 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, this recipe contains mannanoligosaccharide (also known as MOS), a nutritional supplement likely included here as a prebiotic. Prebiotics function to support the growth of healthy bacteria in the pet’s intestinal tract.
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.
Next, we’re pleased to find 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.
And lastly, this food also inlcudes menadione, a controversial form of vitamin K linked to liver toxicity, allergies and the abnormal break-down of red blood cells.
Since vitamin K isn’t required by AAFCO in either of its dog food nutrient profiles, we question the use of this substance in any canine formulation.
Nature’s Harvest Dog Food
The Bottom Line
Judging by its ingredients alone, Nature’s Harvest Dog Food looks like an above-average dry product.
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 27% and a mean fat level of 16%. Together, these figures suggest a carbohydrate content of 48% for the overall product line.
And a fat-to-protein ratio of about 59%.
Near-average protein. Near-average fat. And near-average carbs when compared to a typical dry dog food.
Even when you consider the protein-boosting effect of the flaxseed and dried alfalfa, this looks like the profile of a kibble containing a moderate amount of meat.
Nature’s Harvest is a plant-based dry dog food using a moderate amount of chicken meal as its main source of animal protein, thus earning the brand 4 stars.
However, menadione phobics may wish to ignore our rating and look elsewhere for another product.
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.

A Final Word
The descriptions and analyses expressed in this and every article on this website represent the views and opinions of the author.
The Dog Food Advisor does not test dog food products.
We rely almost entirely on the integrity of the information posted by each company on its website. As such, the accuracy of every review is directly dependent upon the quality of the test results from any specific batch of food a company chooses to publish.
Although it's our goal to ensure all the information on this website is correct, we cannot guarantee its completeness or its accuracy; nor can we commit to ensuring all the material is kept up-to-date on a daily basis.
Each review is offered in good faith and has been designed to help you make a more informed decision when buying dog food.
However, due to the biological uniqueness of every animal, none of our ratings are intended to suggest feeding a particular product will result in a specific dietary response or health benefit for your pet.
For a better understanding of how we analyze each product, please read our article, "The Problem with Dog Food Reviews".
Remember, no dog food can possibly be appropriate for every life stage, lifestyle or health condition. So, choose wisely. And when in doubt, consult a qualified veterinary professional for help.
In closing, we do not accept money, gifts or samples from pet food companies in exchange for special consideration in the preparation of our reviews or ratings.
However, we do receive a fee from Chewy.com for each purchase made as a direct result of a referral from our website. This fee is a fixed dollar amount and has nothing to do with the size of an order or the brand selected for purchase.
