Ingredient Analysis

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 chicken fat. This item 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 doesnt sound very appetizing, chicken fat is actually a quality ingredient.

The fifth ingredient is lamb meal. Lamb meal is considered a meat concentrate and contains nearly 300% more protein than fresh lamb.

The sixth ingredient is menhaden fish meal, another protein-rich meat concentrate.

Menhaden are small ocean fish related to herring. Theyre rich in protein and omega-3 fatty acids. Whats more, in their mid-depth habitat, menhaden are not exposed to mercury contamination as can be typical with deep water species.

This item is typically obtained from the clean, dried, ground tissue of undecomposed whole fish and fish cuttings of commercial fish operations.¹

The seventh ingredient is flaxseed, one of the best plant sources of healthy omega-3 fatty acids. Provided theyve 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 eighth 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.²

Because of its proven safety³ 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.

The ninth 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.

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 4 notable exceptions

First, brewers yeast can be a controversial item. Although its 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 weve 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.

Whats 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 sodium selenite, a controversial form of the mineral selenium. Sodium selenite appears to be nutritionally inferior to the more natural source of selenium found in selenium yeast.

In addition, we note the inclusion of dried fermentation products in this recipe. Fermentation products are typically added as probiotics to aid with digestion.

And lastly, this food also 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.

Nutrient Analysis

Based on its ingredients alone, Health Extension Dog Food looks like an above-average dry product.

The dashboard displays a dry matter protein reading of 27%, a fat level of 20% and estimated carbohydrates of about 45%.

As a group, the brand features an average protein content of 27% and a mean fat level of 15%. Together, these figures suggest a carbohydrate content of 50% for the overall product line.

And a fat-to-protein ratio of about 57%.

Above-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 brewers yeast, this still looks like the profile of a kibble containing a notable amount of meat.

Our Rating of Health Extension Dog Food

Health Extension is a grain-inclusive dry dog food using a notable amount of named meat meal as its dominant source of animal protein, thus earning the brand 4.5 stars.

Highly recommended.

Authority Dog Food Review (Dry)

The Authority product line includes the 20 dry dog foods listed below.

Each recipe includes its AAFCO nutrient profile: Growth (puppy), Maintenance (adult), All Life Stages, Supplemental or Unspecified.

Recipe and Label Analysis

Authority Adult Large Breed Chicken and Rice was selected to represent the other products in the line for detailed recipe and nutrient analysis.

Ingredients Analysis

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 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 fourth ingredient 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.

The fifth ingredient includes oat groats, a whole grain, minimally processed form of oats. With the exception of their caloric content and the fact theyre also gluten free, oat groats can be considered average in nutritional value.

The sixth ingredient is corn gluten meal. Gluten is the rubbery residue remaining once corn has had most of its starchy carbohydrate washed out of it.

Although corn gluten meal contains 60% protein, this ingredient would be expected to have a lower biological value than meat.

And less costly plant-based products like this can notably 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 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.

After the natural flavor, we find chicken fat. This item 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 doesnt sound very appetizing, chicken fat is actually a quality ingredient.

The tenth ingredient is dicalcium phosphate, likely used here as a dietary calcium supplement.

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 Authority product.

With 5 notable exceptions

First, this recipe includes dried egg product, a dehydrated form of shell-free eggs. Quality can vary significantly. Lower grade egg product can even come from commercial hatcheries from eggs that failed to hatch.

In any case, eggs are easy to digest and have an exceptionally high biological value.

Next, we find canola oil. Unfortunately, canola can be a controversial item. Thats 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.

In addition, we note the inclusion of sodium hexametaphosphate, a man-made industrial polymer with no known nutritive value.

HMP is used in making soap, detergents, water treatment, metal finishing and most likely here to decrease tartar build-up on the teeth.

Although some might disagree, were of the opinion that food is not the place for tartar control chemicals or any other non-nutritive substances.

And lastly, the minerals listed here do not appear to be chelated. And that can make them more difficult to absorb. Chelated minerals are usually associated with higher quality dog foods.

Nutrient Analysis

Based on its ingredients alone, Authority looks like an average dry dog food.

The dashboard displays a dry matter protein reading of 28%, a fat level of 13% and estimated carbohydrates of about 51%.

As a group, the brand features an average protein content of 29% and a mean fat level of 14%. Together, these figures suggest a carbohydrate content of 49% for the overall product line.

And a fat-to-protein ratio of about 49%.

Which means this Authority product line contains

Above-average protein. Below-average fat. And near-average carbs when compared to other dry dog foods.

Even when you consider the protein-boosting effect of the corn gluten meal, this looks like the profile of a kibble containing a notable amount of meat.
