The first ingredient in this dog food is corn. Corn is an inexpensive and controversial cereal grain. And aside from its energy content, this grain is of only modest nutritional value to a dog.
For this reason, we do not consider corn a preferred component in any dog food.
The second ingredient is meat and bone meal, a dry “rendered product from mammal tissues, including bone, exclusive of any added blood, hair, hoof, horn, hide trimmings, manure, stomach and rumen contents”.2
Meat and bone meal can have a lower digestibility than most other meat meals.
Scientists believe this decreased absorption may be due to the ingredient’s higher ash and lower essential amino acid content.3
What’s worse, this particular item is anonymous. Since there’s no mention of a specific animal, this ingredient could come from almost anywhere: spoiled supermarket meat, roadkill, dead, diseased or dying livestock — even euthanized farm animals.
Even though meat and bone meals are still considered protein-rich meat concentrates, we do not consider a generic ingredient like this a quality item.
The third ingredient is wheat. Wheat is another cereal grain and subject to the same issues as corn (previously discussed).
The fourth ingredient is wheat mill run, also known as wheat middlings. Though it may sound wholesome, wheat middlings is actually an inexpensive by-product of cereal grain processing.
In reality, wheat mill run is nothing more than milling dust and floor sweepings — and an ingredient more typically found in the lower quality pet foods.
The fifth ingredient is animal fat. Animal fat is a generic by-product of rendering, the same high-temperature process used to make meat meals.
Since there’s no mention of a specific animal, this item could come from almost anywhere: roadkill, spoiled supermarket meat, dead, diseased or dying cattle — even euthanized pets.
For this reason, we do not consider generic animal fat a quality ingredient.
After the poultry flavor, we find potassium chloride, a nutritional supplement sometimes used as a replacement for the sodium found in table salt.
The eighth ingredient is salt (also known as sodium chloride). Salt is a common additive in many dog foods. That’s because sodium is a necessary mineral for all animals — including humans.
However, since the actual amount of salt added to this recipe isn’t disclosed on the list of ingredients, it’s impossible to judge the nutritional value of this item.
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 three notable exceptions…
First, caramel is a coloring agent made by caramelizing carbohydrates. It’s used by pet food manufacturers to impart a golden brown tint to the finished product.
Even though caramel is considered safe by the FDA, we’re always disappointed to find any added coloring in a pet food.
That’s because coloring is used to make the product more appealing to humans — not your dog. After all, do you really think your dog cares what color his food is?
Next, we find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.
And lastly, the minerals listed here do not appear to be chelated. And that can make them more difficult to absorb. Non-chelated minerals are usually associated with lower quality dog foods.
Defender Dog Food Review
Judging by its ingredients alone, Defender Dog Food looks like a below 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.
And a fat-to-protein ratio of about 38%.
Below-average protein. Below-average fat. And above-average carbs when compared to a typical dry dog food.
Free of any plant-based protein boosters, this looks like the profile of a kibble containing a below average amount of meat.
Defender Dog Food is a plant-based kibble using a below average amount of generic meat and bone meal as its main source of animal protein, thus earning the brand 2 stars.
Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content.
