Health Extension Dog Food Review (Canned)

Rating:

Health Extension canned dog food receives the Advisor’s second-highest tier rating of 4 stars.

The Health Extension product line includes 18 canned dog foods.

Each recipe below includes its related AAFCO nutrient profile when available on the product’s official webpage: Growth, Maintenance, All Life Stages, Supplemental or Unspecified.

Important: Because many websites do not reliably specify which Growth or All Life Stages recipes are safe for large breed puppies, we do not include that data in this report. Be sure to check actual packaging for that information.

The first ingredient in this dog food is venison. Venison is considered “the clean flesh derived from slaughtered” venison and associated with skeletal muscle or the muscle tissues of the tongue, diaphragm, heart or esophagus.1

Venison is naturally rich in all ten essential amino acids required by a dog to sustain life.

The second ingredient is venison broth. Broths are of only modest nutritional value. Yet because they add both flavor and moisture to a dog food, they are a common component in many canned products.

The third ingredient is beef. Beef is defined as “the clean flesh derived from slaughtered cattle” and includes skeletal muscle or the muscle tissues of the tongue, diaphragm, heart or esophagus.2

Beef is naturally rich in all ten essential amino acids required by a dog to sustain life.

The fourth ingredient includes pork, another quality, raw item.

The fifth ingredient is pork liver. This is an organ meat sourced from a named animal and thus considered a beneficial component.

The sixth ingredient is turkey. Turkey is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of turkey”.3

The seventh ingredient is ocean fish. This item is typically sourced from clean, undecomposed whole fish and fish cuttings of commercial fish operations.4

Unfortunately, the phrase “ocean fish” is vague and does little to adequately describe this ingredient. Since some fish are higher in omega-3 fats than others, it’s impossible for us to judge the quality of this item.

Both turkey and fish are naturally rich in the ten essential amino acids required by a dog to sustain life.

It’s important to note that the next three ingredients included in this recipe are each a type of legume:

  • Chickpeas
  • Navy beans
  • Lentils

Although they’re a mixture of quality plant ingredients, there’s an important issue to consider here. And that’s the recipe design practice known as ingredient splitting.

If we were to combine all these individual items together and report them as one, that newer combination would likely occupy a significantly higher position on the list.

In addition, legumes contain about 25% protein, a factor that must also be considered when judging the meat content of this dog food.

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 eight notable exceptions

First, we find 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.

Next, flaxseed is 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.

In addition, coconut oil is a natural oil rich in medium-chain fatty acids.

Medium-chain triglycerides have been shown to improve cognitive function in older dogs.5

Because of its proven safety6 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.

Next, yeast extract is the common name for a broad group of products made by removing the cell wall from the yeast organism.

A significant number of these ingredients are added as specialized nutritional supplements while others are used as flavor enhancers.

However, the glutamic acid (and its chemical cousin, monosodium glutamate, or MSG) found in a minority of yeast extracts can be controversial.

That’s because even though the Food and Drug Administration designated these food additives to be safe decades ago7, the agency continues to receive reports of adverse effects.

So, detractors still object to the use of yeast extract and other glutamic acid derivatives and blame them for everything from Alzheimer’s (in humans) to obesity.

In any case, since the label reveals little about the actual type of yeast extract included in any recipe, it’s impossible for us to judge the quality of this ingredient.

We also note the inclusion of chicory root. Chicory is rich in inulin, a starch-like compound made up of repeating units of carbohydrates and found in certain roots and tubers.

Not only is inulin a natural source of soluble dietary fiber, it’s also a prebiotic used to promote the growth of healthy bacteria in a dog’s digestive tract.

Additionally, this recipe contains chia seed, an edible seed nutritionally similar to flax or sesame. Provided they’re first ground into a meal, chia seeds are rich in both omega-3 fatty acids as well as dietary fiber.

However, chia seeds contain about 17% protein, a factor that must be considered when judging the meat content of this dog food.

This food also includes 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, we find selenium yeast. Unlike the more common inorganic form of selenium (sodium selenite), this natural yeast supplement is considered a safer anti-cancer alternative.

Canned Dog Food Review

Judging by its ingredients alone, Health Extension canned dog food looks like an above-average wet 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 41%, a fat level of 27% and estimated carbohydrates of about 24%.

As a group, the brand features an average protein content of 41% and a mean fat level of 29%. Together, these figures suggest a carbohydrate content of 23% for the overall product line.

And a fat-to-protein ratio of about 70%.

Near-average protein. Above-average fat. And below-average carbs when compared to a typical wet dog food.

When you consider the protein-boosting effect of the chickpeas, beans, lentils, flaxseed and chia seed, this looks like the profile of a wet dog food containing a moderate amount of meat.

However, with 51% of the total calories in our example coming from fat versus just 31% from protein, some recipes may not be suitable for every animal.

Bottom line?

Health Extension lists both grain and grain-free canned dog foods using a moderate amount of named meats as its main source of animal protein, thus earning the brand 4 stars.

Highly recommended.

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.
