Dry Dog Food
Estimated Dry Matter Nutrient Content
Ingredients: Chicken, corn meal, ground whole grain sorghum, chicken by-product meal (natural source of chondroitin sulfate and glucosamine), ground whole grain barley, dried beet pulp, chicken flavor, dried egg product, chicken fat (preserved with mixed tocopherols, a source of vitamin E), brewers dried yeast, potassium chloride, salt, dicalcium phosphate, caramel, flax meal, choline chloride, fructooligosaccharides, vitamins (vitamin E supplement, ascorbic acid, vitamin A acetate, calcium pantothenate, biotin, thiamine mononitrate (source of vitamin B1), vitamin B12 supplement, niacin, riboflavin supplement (source of vitamin B2), inositol, pyridoxine hydrochloride (source of vitamin B6), vitamin D3 supplement, folic acid), minerals (ferrous sulfate, zinc oxide, manganese sulfate, copper sulfate, manganous oxide, potassium iodide, cobalt carbonate), calcium carbonate, l-lysine monohydrochloride, dl-methionine, l-tryptophan, l-carnitine, citric acid, rosemary extract

Red items when present indicate controversial ingredients
|Estimated Nutrient Content|
|Dry Matter Basis||25%||17%||50%|
|Calorie Weighted Basis||21%||36%||43%|
The first ingredient in this dog food is 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 account for a smaller part of the total content of the finished product.
The second ingredient is cornmeal, a coarsely ground flour made from dried corn. Corn is an inexpensive and controversial cereal grain of only modest nutritional value to a dog.
For this reason, we do not consider corn a preferred component in any dog food.
The third ingredient is sorghum. Sorghum (milo) 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 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 addition to organs (the nourishing part), this stuff can contain almost anything — feet, beaks, undeveloped eggs — anything except quality skeletal muscle (conventional meat).
On the brighter side, by-product meals are meat concentrates and contain nearly 300% more protein than fresh chicken.
In any case, although this item contains all the amino acids a dog needs, we consider chicken by-products an inexpensive, lower quality ingredient.
The fifth ingredient is barley. Barley is a starchy carbohydrate supplying fiber and other healthy nutrients. However, aside from its energy content, this cereal grain is of only modest nutritional value to a dog.
The sixth 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 chicken flavor, we find 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 ninth 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.
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, flaxseed meal contains one of the best plant-based sources of healthy omega-3 fatty acids. Flax meal is particularly 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, 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.
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 ProActive Health Dog Food
The Bottom Line
Judging by its ingredients alone, Iams ProActive Health looks like 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.
As a group, the brand features an average protein content of 28% and a mean fat level of 16%. Together, these figures suggest a carbohydrate content of 48% for the overall product line.
And a fat-to-protein ratio of about 58%.
Near-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 brewers dried yeast and flax meal, this still looks like the profile of a kibble containing a moderate amount of meat.
Iams ProActive Health is a plant-based kibble using a moderate amount of chicken, chicken by-product meal or lamb meal as its main sources of animal protein, thus earning the brand 3 stars.
Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content.
