The first ingredient in this dog food 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
Beef is naturally rich in all ten essential amino acids required by a dog to sustain life.
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 third ingredient is beef 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 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 pork lung. Pork lung is a protein-rich organ meat that’s also low in fat.
The sixth item 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 next 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 includes carrots. Carrots are rich in beta-carotene, minerals and dietary fiber.
The ninth item is spinach. Due to its exceptional vitamin and mineral content, spinach exhibits a remarkably high nutrient Completeness Score3 of 91.
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 three notable exceptions…
First, we find 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.
Next, 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. Chelated minerals are usually associated with higher quality dog foods.
Purina One SmartBlend
Canned Dog Food Review
Judging by its ingredients alone, Purina One SmartBlend canned dog food looks like an average wet product.
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 43% and a mean fat level of 23%. Together, these figures suggest a carbohydrate content of 25% for the overall product line.
And a fat-to-protein ratio of about 54%.
Above-average protein. Near-average fat. And below-average carbohydrates when compared to a typical wet dog food.
When you consider the protein-boosting effect of the wheat gluten and soy flour contained in some recipes, this looks like the profile of a canned dog food 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. In addition, this same finding also prevents us from awarding the brand a higher rating.
Purina One SmartBlend is a grain-inclusive canned dog food using a moderate amount of named meats and unnamed by-products as its main source 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.
