About Purina

Purina is a huge and renowned global company that is based in St. Louis, Missouri. It is now owned by Nestle and produces several lines of pet food products, including Purina One and Purina Pro Plan. The company is continually expanding with over 50 acres with 16 buildings that include a four-story research facility. 

In 1894, William H. Danforth founded the Robinson-Danforth Commission Company, which was the first balanced food production company in the world. In 1902, the company name transitioned into Ralston Purina and entered into a pet food business after acquiring some small companies. It focuses on researching and developing quality pet foods that contain full nutrition for animals. It is also an alliance between Purina and Dr. Ralston, a nutrition specialist.

In 2001, Nestlé bought Ralston Purina. The two businesses merged under the Purina brand and have been continuously expanding worldwide offering a broad variety of products for your pet's care and nutrition. Now, Purina continues to produce dog foods that vary according to different dietary needs and issues. It created one of the firsts pet food made from an extrusion or specified puppy formulas (kibbles) to address the special needs of puppies. Purina also conducted a 14-year study to develop hypoallergenic products for animals that fit their breeds, life stage, and nutrition.

"Responsibly sourced, expertly prepared, and nutritionally essential" is Purina's assurance to its customers. Until now, all their pet food products have quality ingredients made into different kinds of recipes with feeding guidelines. 

Purina One vs Purina Pro Plan Nutritional Value

Nutrients, vitamins, and minerals are important factors in improving the body's nutrition. The food choices we make determine how much nutrition we are taking in. However, humans and dogs aren't the same when it comes to food. Contrary to what everyone believes, dogs have different dietary needs than humans. Meat and protein are just a part of their needs to get a balanced diet. It takes many ingredients and nutrition in order to be at their best and that is where kibbles come in.

Both Purina One and Purina Pro Plan pass the standard amount of the three major components of dog food products which are protein, fats, and fiber with very slight differences. Take a look at this:

Purina One:

  • Crude Protein: 31.6%
  • Crude Fiber: 4.3%
  • Crude Fat: 17.2% 

Purina Pro Plan:

  • Crude Protein: 31.8%
  • Crude Fiber: 4.4%
  • Crude Fat: 17.9%


Both brands have roughly the same amount of protein content. This is an essential part of the nutritional value for dog foods since protein can prevent dogs from developing a wide-range of serious health problems. The protein content provides amino acids, which are very important for giving energy, cellular regeneration, healthy coat, skin, ligaments, and muscle production.  Dogs cannot produce protein naturally that is why it must be added to their daily diet. Meaning, poor-quality dog food can lead to the deterioration of your pup's immune system because of vitamin deficiencies. 

The only difference between the two brands is that Purina Pro Plan has more protein by point 2%. Both brands list real meat as their first ingredient but the meat by-products go next, which is a major downfall. Meat by-products are the most controversial ingredient since they are mostly made of ground rendered parts of poultry carcasses and contain bones, offal, and beak. It may not be totally harmful to your pets but it contains less to zero nutrition. 


The fiber content helps in the dog's digestive system because of its ability to enhance food digestion and constipation since dogs tend to chew or swallow their food improperly. Both Purina One and Purina Pro Plus have sufficient fiber content in their products, it's just that Purina Pro Plan is higher by less than 1%. But both have done their research as to what constitutes a healthy balanced diet that would match your pup's needs. 

A lack of fiber on the diet can lead to severe constipation as well as problems in their digestive and anal glands. Fiber also aids in the absorption of nutrients from food in the gut. Basically, it is an all-around essential part of a healthy diet.


Fat content in dog food should be enough to aid the absorption of fat-soluble vitamins as well as improve your dog's palatability. The Purina Pro Plan has a higher content of fats by point 7%. If you think that your dog needs more fats in the diet, then you have to go for this product. Also, the suggested content of fat ratio from AAFCO is only 2:1. Meaning, the fat content of the Purina Pro Plan is higher than what is suggested by professionals. 

It is still important that your dog gains more nutrition from protein before getting it from fats. Too many fats in the diet cause overweight or obesity and could also lead to inactive pooches.


Purina Pro goes better when it comes to nutritional value. This product has more nutrient content and has a wide variety of formulas for your pup. Your dogs might thank you if it suits best with their taste.

Purina One vs Purina Pro Plan Ingredients

Both Purina One and Purina Pro Plan contain controversial ingredients that might cause allergic reactions to your sensitive dogs. Many of their products use these ingredients:

  • Brewers rice
  • Corn gluten meal
  • Animal by-products
  • Whole grain wheat
  • Animal fat
  • Wheat gluten
  • Soybean flour
  • Caramel color
  • Powdered cellulose

Here is the controversial ingredient that is only used by Purina One:

  • Turkey by-product meal

And here are the controversial ingredients that are only used by Purina Pro Plan:

  • Poultry
  • Garlic Powder
  • Corn grits
  • Chicken by-products
  • Dried corn syrup
  • Canola oil
  • Poultry giblets


We would choose Purina One when it comes to safer ingredients since we can see that Purina Pro Plan contains several controversial ingredients that may be harmful to your pets.

Purina One vs Purina Pro Plan Flavors

The flavor is an important factor when purchasing dog food for your pets. Like humans, dogs are always picky and can be bored of the same food served every day. Luckily, Purina made a variety of flavors according to their different brands. Also, most of their flavors have almost the same ingredients with just a slight difference. Meaning, you can easily transition your dog to different food flavors if he becomes bored with his usual food. 

Purina One's original flavor is chicken, corn, peas with lamb and rice, or chicken and rice as alternatives. Moreover, their dietary specification kibbles for puppies, adults, and sensitive dogs offer salmon & rice flavor, or salmon & tuna with added peas and carrots.

Purina One's popular flavors:

  • wholesome chicken and rice entrée
  • Salmon and trout recipe
  • Beef and rice entree
  •  Real salmon and tuna formula

On the other hand, Purina Pro Plan's standard flavor is chicken, rice, and corn. Kibbles for puppies, adults, and sensitive dogs have lamb & rice, salmon & rice, and chicken & egg recipes.

Purina Pro Plan's popular flavors:

  • HA hydrolyzed chicken formula flavor
  • Chunky chicken entrée and Savor shredded chicken and rice.
  •  Cesar gourmet wet
  • Salmon and rice formula


Purina Pro Plan has a better option for flavors compared to Purina One. Having a variety of flavors to choose from can give so much advantage to your dogs. Again, with Purina Pro Plan, you won't have a hard time switching to different flavors to address your dog's appetite and nutritional needs. 

Purina One vs Purina Pro Plan Cost

Affordability is another important factor that buyers consider when buying supplies for their pets. Even when a particular product meets the AAFCO standard, the price always plays a part especially if it is worth the quality or if the budget is tight. There have been several reports that brands exaggerate the prices and claim that it comes with extraordinary ingredients and benefits even if it shows the other way around. 

So, Purina One and Purina Pro Plan are both affordable when it comes to various sizes like 5lb and 16lb. Meaning, you can choose either of the two depending on your pet's preference and need. Nonetheless, Purina Pro Plan costs a little bit higher than Purina One. That is why some buyers prefer Purina One since it is cheaper and comes almost the same in quality when it comes to pet food. 

But it is no means that Purina Pro Plan is not worth your dollar. As we have stated above, it has more choices of flavors and also contains a little bit more nutritional value. But if you have a tighter budget for your pet's food, then go for Purina One since it is cheaper yet has good quality content, too.


Purina One is the more cost-efficient product. It has a lower cost plus, it offers high-quality ingredients. If your budget is a concern, Purina One is a good choice for your fur baby.
