The first item in this dog food is water, which adds nothing but moisture to this food. Water is a routine finding in most canned dog foods.

The second ingredient includes 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

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

The fourth item lists meat by-products, slaughterhouse waste. This is what’s left of slaughtered animals after all the prime cuts have been removed.

With the exception of hair, horns, teeth and hooves, this stuff can include heads, ovaries or developing fetuses.1

What’s worse, this particular item is anonymous. It doesn’t even specify the source animal. So, this meat can come from almost anywhere, even diseased or dying livestock.

Although meat by-products can be high in protein, we do not consider a generic ingredient like this a quality item.

The fifth ingredient lists 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 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 seventh item 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.

Guar gum is a gelling or thickening agent found in many wet pet foods. Refined from dehusked guar beans, guar gum can add a notable amount of dietary fiber to any product.

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 have much of an effect on the overall rating of this product.

With two 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 does appear to be some recent controversy regarding its long term biological safety.

And lastly, the minerals 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 Canned Dog Food
The Bottom Line

Judging by its ingredients alone, Purina One appears to be an 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.

The dashboard displays a dry matter protein reading of 36%, a fat level of 32% and an estimated carbohydrate content of 24%.

As a group, the brand features an average protein content of 42% and an average fat level of 25%. Together, these figures suggest an overall carbohydrate content of 25% for the full 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 canned dog food.

Free of any plant-based protein boosters, this is the profile of a wet food containing a moderate amount of meat.

Bottom line?

Purina One canned dog food is a meat-based wet product using an average amount of poultry, beef or lamb as its main sources of animal protein… thus earning the brand 3 stars.

Special Alert

Rice ingredients can sometimes contain arsenic. Until the US FDA establishes safe upper levels for arsenic content, pet owners may wish to limit the total amount of rice fed in a dog's daily diet.
