As you browse through the category of dog foods, you will probably come across thousands of options. You will even find a single brand like Purina, which has a good reputation and a large customer base. But when you compare diets like Purina Pro Plan vs Purina One, they confuse you even more.

Not that the two dog nutritions are inferior, but because they seem to share a lot in common, yet have different prices. The latter is relatively cheaper, and this has even made many customers question why they should pay more on Purina Pro Plan. Yet its counterpart delivers closer content value and at a lower cost.

Thankfully, this article will revolve around that angle as we try distinguishing the two dog food brands. Thereby helping you understand and make a better choice in regards to the nutrition needs of your furry friend.

Before we come to that, nonetheless, let’s look at how Purina One and Pro Plan came in to being.

Introducing Purina Pro Plan and Purina One

Overall, Purina is one of the top four sought after providers of cats and dog meals. The brand is over a century old, with its initial debut dating back in 1894. At the time, the provider was feeding farm animals in general, and under a different name- Robinson-Danforth Commission Company.

In the year 1986, Ralston Purina, as it was called then, managed to use real meat in their extrusion “kibble” process. With the innovation, they decided to do away with their animal feed business and focus on only cat and dog food.

After all, the two are the only farm animals that would use flesh diets in the new product line, Purina Pro Plan. According to the company website, the brand was the first to have real meat as the number one ingredient in its kibble.

After our extensive research, though, we have come to learn Purina One launched around the same time, and also it has meat as the no. #1 constituent. As we’ve just said, the two pet food brands share a lot of features, including ingredients and some Guaranteed analysis.

Although the company didn’t state why so, our best guess is that Purina One was to make the Pro Plan formulas more accessible. It was like a “basic” version that can serve the general nutrition needs of your dog when at a tight budget.

Comparing Purina Pro Plan vs Purina One Dog Food

Ingredients Use

While comparing Purina Pro Plan vs Purina One on ingredient use, they both use compounds obtained from natural sources. Also, they use real meat as the first ingredient and main source of protein. Thereby offering your pet with nutrition similar to what his wolverine ancestors rely on to survive.

Even so, the Purina Pro Plan does have a wider array of products than its sibling. It offers more than eighty different flavors, whereas the Purina One has less than half of that. In other words, the latter has limited options to fully serve your dog’s specific taste and needs.

Nutritional value

By simple definition, this is a measure of the essential nutrients contained in a particular dog recipe. It’s the same as the guaranteed analysis, which aims on advising you, the dog owner, on the nutrient content of the product.

At a minimum, AAFCO requires every pet food brand to list minimum percentages of crude protein and crude fat. And Crude fiber and moisture with their maximum ratios. The four are the most vital for a healthy balanced diet. So, the listing of the rest of nutrient content is not a must, though it can guide the buyer on what other minerals and vitamins to expect.

With our two dog food brands, multiple of their recipes have like the content of protein, fats, and fiber.

If it’s the large breed diets, for instance, several formulas from Pro Plan and Purina One have 26% protein, 12% Fats, 4.5% Fiber content, and 12% moisture. For the others, nonetheless, the line of Pro Plan has over a dozen products with high protein while ONE brand has lesser.

Product Safety

From their Pro Plan page, Purina highlights that their goal is to deliver dog food that is high quality and safe for your pooch. They further state on their main website that they do all the processing on their own facilities so that they can observe the quality.

If you consider this, plus their long-established craftsmanship, hundreds of scientists, animal nutritionists and veterinarians, one would, therefore, expect lesser product recalls.

Sadly, this is not the case. The brand has issued a handful of recalls across their various dog foods. If we can collate Purina One vs Pro Plan, however, you will find that each has been affected at a small degree.

For example, in 2013, the company had to recall a batch from Purina ONE beyOnd due to possible contamination with salmonella. They asked the owners who had already bought the product to refrain from giving to their pets. The affected lot was 3.5lb dry dog food bags, with production code 31071083, and listed “Best By” Oct 2014.

In 2016, Purina also came to notice some of their wet dog food tubs had inadequate vitamins and minerals. Amongst the affected meals brands was the Pro plan Savory diet. Again, the pet food maker called out to the owners and requested them to stop offering the affected batch to their dogs.


Even when a particular meets the standards set by AAFCO, its affordability matters a lot. You might have several dogs or a tight budget, but still you want kibble to mix with your homemade recipes.

With our two dog food brands, they are both affordable as they come in various sizes, including small bags like 5lb and 16lb. Therefore, you can always get your favorite dog meal with any budget.

Nonetheless, the Purina Pro Plan tends to cost more than the majority of recipes from its sibling. Hence, the reason some buyers fall for the Purina One, which is more accessible and offers benefits closer to its counterpart.

This is not to mean the Pro Plan brand is less worthy of getting. No. As we have just said, it has more dog meal flavors to choose, and also do include more additional vitamins. As such, you have a better chance to serve your picky canine, as well as satisfy his unique nutritional demands.

Here is a table that summarizes the differences and likeness between Purina Pro Plan vs Purina One dog food.
