Rating: 




Iams Premium Protection dry dog food gets the Advisor’s mid-tier rating of three stars.
The Iams Premium Protection product line includes three dry dog foods.
Even though Iams clearly states on its website each product meets AAFCO nutrition profiles for adult maintenance, we believe this claim to be a publishing error. That’s because puppy products normally comply with guidelines for “growth” or “all life stages”.
- Iams Premium Protection Puppy
- Iams Premium Protection Adult
- Iams Premium Protection Senior
Iams Premium Protection Adult dog food was selected to represent the others in the line for this review.

Red items when present indicate controversial ingredients
The first ingredient in this dog food is chicken by-product meal… a dry rendered product of slaughterhouse waste. It’s made from what’s left of a slaughtered chicken after all the prime cuts have been removed.
In a nutshell, chicken by-products are those unsavory leftovers usually considered “unfit for human consumption”.
This stuff can contain almost anything… feet, beaks, undeveloped eggs… anything (that is) but skeletal muscle (real meat).
On the brighter side, by-product meals are meat concentrates and contain nearly 300% more protein than fresh chicken.
The second ingredient mentions corn meal. Corn meal is a coarsely ground flour made from dried corn. Now, contrary to what you may have heard, corn isn’t necessarily a bad ingredient.
On the other hand, although there’s no way to know for sure here, the corn used in making many pet foods can be similar to the kind used to make feed for livestock.
And that can sometimes be problematic.
What’s more, corn is commonly linked to canine food allergies1.
For these reasons, we rarely consider corn a preferred component in any dog food.
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 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.
Fish meal is another high-protein meat concentrate.
Unfortunately, this particular item is anonymous. The term “fish” does little to properly describe this ingredient.
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 sixth ingredient includes chicken. Although it is a quality item, raw chicken 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 occupy a lower position on the list.
The seventh 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. Though it doesn’t sound very appetizing, chicken fat is a quality ingredient.
The eighth item includes 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.
Following the chicken flavor, we find 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.
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 have much of an effect on the overall rating of this product.
With two notable exceptions…
First, we find no evidence of probiotics… friendly bacteria applied to the surface of the kibble after processing.
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 Premium Protection Dog Food
The Bottom Line
Judging by its ingredients alone, Iams Premium Protection appears to be an 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.
The dashboard displays a dry matter protein reading of 30%, a fat level of 13% and estimated carbohydrates of about 49%.
As a group, the brand features an average protein content of 31% and a mean fat level of 16%. Together, these figures suggest a carbohydrate content of 45% for the overall product line.
Above-average protein. Average fat. And below-average carbs… as compared to a typical dry dog food.
With no evidence of any plant-based protein boosters, this looks like the profile of a kibble containing a notable amount of meat.
Bottom line?
Iams Premium Protection is a grain-based dry dog food using a significant amount of chicken by-product meal as its main source of animal protein… thus earning the brand three stars.
Recommended.
