The first ingredient in this dog food is ocean fish. Although it’s rich in protein, raw fish contains about 80% 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.
Unfortunately, the phrase “ocean fish” is generic 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.
Which brings us to brewers rice… the second and (more likely) the dominant ingredient in this recipe.
Brewers rice represents the small grain fragments left over after milling whole rice.
This is an inexpensive cereal grain by-product and not considered a quality ingredient.
The third ingredient is sorghum. Sorghum is a starchy cereal grain with a nutrient profile similar to corn.
Since it is gluten-free and boasts a smoother blood sugar behavior than other grains, sorghum may be considered an acceptable non-meat ingredient.
The fourth ingredient is fish meal. Because it is considered a meat concentrate, fish meal contains almost 300% more protein than fresh fish itself.
Unfortunately, this particular item is anonymous. Like the ocean fish described above, we would have preferred to have known the source species.
Fish meal is commonly made from the by-products of commercial fish operations.
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, and based upon this fish meal’s location on the list of ingredients, we would expect to find at least a trace of ethoxyquin in this product.
The fifth ingredient lists barley. Barley is a starchy carbohydrate supplying fiber and other healthy nutrients. Unlike grains with a higher glycemic index (like rice), barley can help support stable blood sugar levels in dogs.
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 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 have failed to hatch.
In any case, eggs are easy to digest and have an exceptionally high biological value.
The eighth ingredient lists 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 ninth ingredient is fish digest… a chemically hydrolyzed brew of fish by-products. Animal digests are usually sprayed onto the surface of a dry dog food to improve its taste.
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 dried yeast. Brewers yeast can be a controversial item. Although it’s a by-product of the beer making process, this ingredient contains about 45% protein… and is rich in 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.
What’s more, a vocal minority insist yeast can increase the risk of developing the life-threatening condition known as bloat. However, this is something we’ve not been able to scientifically verify.
In any case, unless your dog is specifically allergic to it, yeast can be considered a nutritious additive.
Next, this recipe contains fructooligosaccharide… an alternative sweetener1 probably used here as a prebiotic. Prebiotics function to support the growth of healthy bacteria in the large intestine.
Thirdly, apple pomace includes the pulpy solids that remain after pressing apples to extract the juice. It is most likely used here for its fiber content.
And lastly, 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.
Iams Sensitive Naturals Dog Food
The Bottom Line
Judging by its ingredients alone, Iams Sensitive Naturals looks to be a below-average dry dog food.
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.
Below-average protein. Below-average fat. And above-average carbs when compared to a typical dry dog food.
Free of any plant-based protein boosters, this looks like the profile of a kibble containing a moderate amount of meat.
Iams Sensitive Naturals dog food is a grain-based kibble using a moderate amount of fish as its main source of animal protein… thus earning the brand 2.5 stars.
