Purina one vs Purina pro: Ingredients Quantity and Quality

On the basis of ingredient use, Purina Pro Plan and Purina One both use compounds obtained from natural sources. In addition, real meat is used as a primary ingredient and the primary source of protein.

Protein Content

In a dog’s diet, protein plays an extremely important role. Dogs can suffer from several serious health problems if they don’t get enough protein.

Regardless of which formula you choose, your dog will get sufficient amino acids to keep him healthy and strong.

There is only a slight difference in Purina Pro Plan small breed kibble since it has 1% more protein. The first ingredient for both brands is real meat, but the second ingredient is meat by-products.  Due to that added protein, we consider Purina Pro one of our favorite foods for smaller breeds such as the Yorkie or Shih-tzu.

Fat Content

All dogs should eat fat as it delivers an array of benefits such as strong muscles, healthy blood pressure, fat-soluble vitamins, and adds flavor to the food.  

There is no difference in crude fat content between Purina One and Purina Pro Plan. When it comes to wet dog foods, Purina One contains about 6.50% more.

Fiber Content

The crude fiber content for both formulas is 3%, which is standard in most dry dog foods. In these recipes, rice and wheat offer the most fiber.

Beet pulp, however, is not one of the high-fiber ingredients. Nevertheless, the vegetables in Purina One Smartblend dog food are more fiber-rich than those in Purina Pro Plan.

Fiber plays a key role in digestion. Maintains a dog’s bowel movements and keeps their stools firm. Constipation and problems with the anal glands can result from not getting enough fiber in their diet


As a flavor option, Purina ONE offers Chicken, peas, and corn, and as an alternative, Lamb and rice or Chicken. Salmon and rice flavor is available for puppies, senior dogs, and picky eaters dogs.

Purina Pro Plan offers in the range of Chicken, rice, and corn, but there are also other flavors available for picky eaters. such as lamb, rice, and salmon.


In the category of cost, Purina ONE wins. Compared to Pro Plan formulas, they are cheaper and have fewer high-quality ingredients. Purina ONE is a great choice if cost is your primary concern
