IAMS Proactive Health Dog Food Review (Dry)

IAMS Proactive Health product range consists of 19 recipes with ratings varying from 2 to 2.5 stars. The average rating of the whole range is 2.5 stars.

This IAMS range includes formulas tailored to breeds of all sizes and ages. While each recipe provides some nutrients, we would prefer to see ingredients with a higher nutritional value. It does redeem itself a little, with the presence of real protein as the first ingredient.

The table below shows each recipe in this range including our rating and the AAFCO nutrient profile: Growth (puppy), Maintenance (adult), All Life Stages, Supplemental or Unspecified.

Recipe and Label Analysis

IAMS Proactive Health Minichunks Chicken and Whole Grain was selected to represent the other products in the line for detailed recipe and nutrient analysis.

Ingredients 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 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 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 next 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 choice cuts have been removed.

On the brighter side, by-product meals are meat concentrates and contain nearly 300% more protein than fresh chicken.

The quality of this ingredient can vary, depending on the caliber of the raw materials obtained by the manufacturer.

The fifth ingredient is soybean germ meal, a soy-based product containing high levels of daidzein and glycitein — the isoflavones found to be beneficial in feline weight management.

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 natural flavor, we find flaxseed, 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.

The next 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 tenth 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 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 Iams product.

With four notable exceptions…

First, caramel is a natural coloring agent made by caramelizing carbohydrates. It’s used by pet food manufacturers to impart a golden brown tint to the finished product.

However, the concentrated version of this ingredient commonly known as caramel coloring has been more recently considered controversial and found to cause cancer in laboratory animals.¹

In any case, even though caramel is considered safe by the FDA, we’re always disappointed to find any added coloring in a pet food.

That’s because coloring is used to make the product more appealing to humans — not your dog. After all, do you really think your dog cares what color his food is?

We also find flaxseed, 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 cat food.

Next, this recipe contains fructooligosaccharide, an alternative sweetener² 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. Chelated minerals are usually associated with higher quality dog foods.

Nutrient Analysis

Based on its ingredients alone, Iams Proactive Health Minichunks Chicken & Whole Grain looks like an above-average dry product.

The dashboard displays a dry matter protein reading of 28.8%, a fat level of 16.3% and estimated carbohydrates of about 42.6%.

As a group, the brand features an average protein content of 29.4% and a mean fat level of 16%. Together, these figures suggest a carbohydrate content of 41.7% for the overall product line.

And a fat-to-protein ratio of about 54%.

Which means this Iams product line contains…

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, this looks like the profile of a kibble containing a notable amount of meat.

Our Rating of IAMS Proactive Health Dry Grain Inclusive Dog Food

The product range includes chicken as the primary ingredient, which is a positive aspect. However, it contains meat by-products and controversial ingredients that provide only modest nutritional value, along with added colors, consequently bringing down the overall rating to 2.5 stars.

About

IAMS was founded in Ohio in 1946 by self-taught animal nutritionist, Paul Iams. He spent time learning about the importance of protein in pet food and then created his first small batch in the 1950s. At this time Iams was considered a premium brand producing high-quality dog food.

Iams is currently owned by Mars. However, it is now considered more of a budget-friendly option rather than a premium brand.
