The first ingredient in this dog food is chicken. Although it is a quality item, raw chicken contains up to 73% 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 is ground brown rice, another name for rice flour. Ground rice is made from either white or brown rice and is considered a gluten-free substitute for wheat flour.
The fourth ingredient is oatmeal, a whole-grain product made from coarsely ground oats. Oatmeal is naturally rich in B-vitamins, dietary fiber and can be (depending upon its level of purity) gluten-free.
The fifth 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 sixth ingredient is lamb meal, another protein-rich meat concentrate.
The seventh ingredient is menhaden fish meal, yet another high protein meat concentrate.
Menhaden are small ocean fish related to herring. They are rich in protein and omega-3 fatty acids.
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 coconut oil, a natural oil rich in medium-chain fatty acids.
Medium-chain triglycerides have been shown to improve cognitive function in older dogs.1
Because of its proven safety2 as well as its potential to help in the treatment of canine cognitive dysfunction syndrome (CDS) and chronic skin disorders, MCT can be considered a positive addition to this recipe.
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, 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.
Next, this recipe contains 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.
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 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.
Health Extension Dog Food Review
Judging by its ingredients alone, Health Extension 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 14%. Together, these figures suggest a carbohydrate content of 51% for the overall product line.
And a fat-to-protein ratio of about 53%.
Near-average protein. Below-average fat. And above-average carbs when compared to a typical dry dog food.
Even when you consider the protein-boosting effect of the flaxseed and brewers yeast, this looks like the profile of a kibble containing a moderate amount of meat.
Health Extension is a plant-based dry dog food using a moderate amount of named meat meals 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.
