The first item in this dog food 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”.1
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.2
What’s worse, this particular item is anonymous. It doesn’t even specify the source animal.
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 second ingredient includes corn. Corn is an inexpensive and controversial cereal grain of only modest nutritional value to a dog.
For this reason, we do not consider corn a preferred component in any dog food.
The third ingredient is wheat middlings, commonly known as “wheat mill run”. Though it may sound wholesome, wheat mill run is actually an inexpensive by-product of cereal grain processing.
In reality, wheat middlings are nothing more than milling dust and floor sweepings — and an ingredient more typically found in the lower quality pet foods.
The fourth ingredient is wheat. Wheat is another problematic grain and subject to the same issues as corn (previously discussed).
The fifth ingredient lists corn gluten meal. Gluten is the rubbery residue remaining once corn has had most of its starchy carbohydrate washed out of it.
Compared to meat, glutens are inferior grain-based proteins lower in some of the essential amino acids dogs need for life.
This inexpensive plant-based ingredient can significantly boost the total protein reported on the label — a factor that must be considered when judging the actual meat content of this dog food.
The sixth item 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 livestock.
For this reason, we do not consider generic animal fat 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 animal digest. Animal digest is a chemically hydrolyzed mixture of animal by-products that is usually sprayed onto the surface of a dry kibble to improve its taste.
Following the salt, we find fish 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.3
Unfortunately, this particular item is anonymous. Because various fish contain different types of fats, we would have preferred to have known the source species.
What’s more, the controversial chemical ethoxyquin is frequently used as a preservative in fish meals.
But because it’s usually added to the raw fish before processing, the chemical does not have to be reported to consumers.
We find no public assurances from the company this product is ethoxyquin-free.
Without knowing more, we would expect to find at least a trace of ethoxyquin in this product.
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, we find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.
Next, 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.
And lastly, this dog food recipe also contains 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.
Caliber Dog Food
The Bottom Line
Judging by its ingredients alone, Caliber Dog Food looks to be a below-average kibble.
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 26% and a mean fat level of 16%. Together, these figures suggest a carbohydrate content of 49% for the overall product line.
And a fat-to-protein ratio of about 62%.
Below-average protein. Near-average fat. And near-average carbs when compared to a typical dry dog food.
In addition, when you consider the protein-boosting effect of the corn gluten meal, this looks like the profile of a kibble containing only a modest amount of meat.
Caliber Dog Food is a grain-based kibble using a modest amount of meat and bone meal as its main source of animal protein, thus earning the brand 1 star.
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.
