The first ingredient in this dog food is beef broth. Broths are nutritionally empty. But because they add moisture to a dog food they are a common finding in many canned products.

The second ingredient is beef. Beef is defined as “the clean flesh derived from slaughtered cattle” and includes skeletal muscle or the muscle tissues of the tongue, diaphragm, heart or esophagus.1

The third ingredient is chicken. Chicken is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of chicken”.1

Both beef and chicken are naturally rich in the ten essential amino acids required by a dog to sustain life.

The fourth 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 fifth ingredient includes meat by-products, an item made from slaughterhouse waste. This is what’s left of slaughtered animals after all the prime striated muscle cuts have been removed.

With the exception of hair, horns, teeth and hooves, this item can include almost any other part of the animal.1

What’s worse, this particular item is anonymous. So, the meat itself can come from any combination of cattle, pigs, sheep or goats — which can make identifying specific food allergies impossible.

Although most meat by-products can be nutritious, we do not consider such vaguely described (generic) ingredients to be as high in quality as those derived from a named animal source.

The sixth ingredient is brown rice, a complex carbohydrate that (once cooked) can be fairly easy to digest. However, aside from its natural energy content, rice is of only modest nutritional value to a dog.

The seventh ingredient is oatmeal, a whole-grain product made from coarsely ground oats. Oatmeal is naturally rich in B-vitamins, dietary fiber and can be (depending upon its level of purity) gluten-free.

The eighth ingredient is spinach. Due to its exceptional vitamin and mineral content, spinach exhibits a remarkably high nutrient Completeness Score4 of 91.

The ninth ingredient is egg product, an unspecified (wet or dry?) 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 affect the overall rating of this product.

With two notable exceptions

First, carrageenan is a gelatin-like thickening agent extracted from seaweed. Although carrageenan has been used as a food additive for hundreds of years, there appears to be some recent controversy regarding its long term biological safety.

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.

Purina One SmartBlend Canned Dog Food
The Bottom Line

Judging by its ingredients alone, Purina One SmartBlend looks like an average canned 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 36%, a fat level of 32% and estimated carbohydrates of about 24%.

As a group, the brand features an average protein content of 42% and a mean fat level of 25%. Together, these figures suggest a carbohydrate content of 25% for the overall product line.

And a fat-to-protein ratio of about 58%.

Near-average protein. Above-average fat. And below-average carbs when compared to a typical canned dog food.

Free of any plant-based protein boosters, this looks like the profile of a wet product containing a moderate amount of meat.

However, with 56% of the total calories in our example coming from fat versus just 27% from protein, some recipes may not be suitable for every animal.

Bottom line?

Purina One SmartBlend is a meat-based canned dog food using a moderate amount of poultry, beef or liver 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 and (when appropriate) their fat-to-protein ratios.
