Ingredient Analysis

The first ingredient in this dog food is chicken 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 second ingredient is chicken. Chicken is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of chicken”.1

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

The next ingredient is liver. Normally, liver can be considered a quality component. However, in this case, the source of the liver is not identified. For this reason, it’s impossible to judge the quality of this item.

The fourth ingredient is wheat gluten. Gluten is the rubbery residue remaining once wheat has had most of its starchy carbohydrate washed out of it.

Although wheat gluten contains 80% protein, this ingredient would be expected to have a lower biological value than meat.

And less costly plant-based products like this can notably boost the total protein reported on the label — a factor that must be considered when judging the actual meat content of this dog food.

The fifth ingredient is soy flour, a high-protein by-product of soybean processing.

Although soy flour contains about 51% protein, this ingredient would be expected to have a lower biological value than meat, and can notably boost the total protein reported on the label — a factor that can’t be ignored when judging the actual meat content of this product.

The next ingredient is pork lung. Lung is a protein-rich organ meat that’s also low in fat.

The seventh ingredient is duck. Duck is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of duck”.2

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

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 Purina product.

With 3 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.3

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?

Next, this recipe contains sodium selenite, a controversial form of the mineral selenium. Sodium selenite appears to be nutritionally inferior to the more natural source of selenium found in selenium yeast.

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, Purina One SmartBlend True Instinct canned dog food looks like an average wet product.

The dashboard displays a dry matter protein reading of 55%, a fat level of 18% and estimated carbohydrates of about 20%.

As a group, the brand features an average protein content of 55% and a mean fat level of 18%. Together, these figures suggest a carbohydrate content of 20% for the overall product line.

And a fat-to-protein ratio of about 32%.

Which means this Purina product line contains…

Above-average protein. Below-average fat. And below-average carbs when compared to other canned dog foods.

Even when you consider the protein-boosting effect of the wheat gluten and soy flour, this looks like the profile of a wet product containing at least a moderate amount of meat.

Our Rating of Purina One SmartBlend True Instinct Canned Dog Food

Purina One SmartBlend True Instinct is a grain-inclusive canned dog food using a moderate amount of named meats and unnamed meat by-products as its dominant source of animal protein, thus receiving 4 stars.

Highly recommended.
