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 brewers rice. Brewers rice is a cereal grain by-product consisting of the small fragments left over after milling whole rice. Aside from the caloric energy it contains, this item is of only modest nutritional value to a dog.
The third 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 fourth 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 fifth ingredient includes oat groats, a whole grain, minimally processed form of oats. With the exception of their caloric content and the fact they’re also gluten free, oat groats can be considered average in nutritional value.
The sixth ingredient includes fish meal, another protein-rich meat concentrate.
Fish meal is typically obtained from the “clean, dried, ground tissue of undecomposed whole fish and fish cuttings” of commercial fish operations.2
Unfortunately, this particular item is anonymous. Because various fish contain different types of fats, we would have preferred to have known the source species.
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 dried egg, a dehydrated powder made from shell-free eggs. Eggs are easy to digest and have an exceptionally high biological value.
The ninth ingredient is canola oil. Unfortunately, canola can be a controversial item. That’s because it can sometimes (but not always) be derived from genetically modified rapeseed.
Yet others cite the fact canola oil can be a significant source of essential omega-3 fatty acids.
In any case, plant-based oils like canola are less biologically available to a dog than fish oil as a source of quality omega-3 fats.
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 five notable exceptions…
First, flaxseed meal is one of the best plant-based sources of healthy omega-3 fatty acids. Flax meal is particularly 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.
Next, brewers yeast can be a controversial item. Although it’s a by-product of the beer making process, this ingredient is rich in minerals and other healthy nutrients.
Fans believe yeast repels fleas and supports the immune system.
Critics argue yeast ingredients can be linked to allergies. This may be true, but (like all allergies) only if your particular dog is allergic to the yeast itself.
In addition, a vocal minority insists yeast can increase the risk of developing the life-threatening condition known as bloat. However, this is a claim we’ve not been able to scientifically verify.
In any case, unless your dog is specifically allergic to it, yeast can still be considered a nutritious additive.
What’s more noteworthy here is that brewers yeast contains about 48% protein, a factor that must be considered when judging the actual meat content of this dog food.
In addition, we find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.
Next, this food 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.
And lastly, this food includes 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.
Black Gold Signature Series Dog Food The Bottom Line
Judging by its ingredients alone, Black Gold Signature Series Dog Food looks like an 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.
The dashboard displays a dry matter protein reading of 28%, a fat level of 16% and estimated carbohydrates of about 49%.
As a group, the brand features an average protein content of 30% and a mean fat level of 19%. Together, these figures suggest a carbohydrate content of 44% for the overall product line.
And a fat-to-protein ratio of about 63%.
Near-average protein. Above-average fat. And below-average carbs when compared to a typical dry dog food.
Even when you consider the protein-boosting effect of the flaxseed meal and brewers yeast, this looks like the profile of a kibble containing a moderate amount of meat.
However, it’s unfortunate the company chose to include menadione in its recipe. Without this controversial ingredient and minus the brewers rice, we may have been compelled to award this line a higher rating.
Black Gold Signature Series is a plant-based dry dog food using a moderate amount of chicken or lamb meals as its main sources of animal protein, thus earning the brand 3.5 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.
