Dog food brands that have been around for a long time have always competed against one another, promising to have the best dog food on the market. Because of this, it can be tough to find the best dog food that meets your dog’s needs. Some companies have also falsely advertised their products, making it even harder to find the right one. Thankfully, we’ve done the research to help you decide.
Purina and Iams have been around for a long time, often compared against each other to see which one is the best. We decided to put both dog food brands to the test, with one brand standing out as the winner. Here is our comparison of Purina Pro Plan and Iams ProActive Health.
A Sneak Peek at the Winner: Purina Pro Plan
Purina Pro Plan offers complete and balanced nutrition for your dog, regardless of age, size, and activity level. If you’re looking for a wide variety of proteins and recipes to choose from, Purina Pro Plan has a type of food for just about any dog.
The Winner of Our Comparison:
Though Purina was not officially formed until 2001, Purina’s origins go much farther than that. What started as a small animal feed business in 1894 named the Robinson-Danforth company slowly grew into a booming business called the Ralston Purina company in 1901.
Eventually, Ralston Purina was purchased by Nestle, combining with their current cat products to become one of the largest animal food companies at that time. After the merger, the Purina Pro Plan dog food selection was created to give dogs a nutritious, balanced diet.
Purina as a Company
Purina and its origins have been around for a while, so they have been involved in multiple areas. In 2011, Nestle Purina sponsored the Westminster Dog Show, one of the largest dog shows around.
Nestle Purina also won an award in 2011 for its organized manufacturing productions and waste reduction called the Malcolm Baldrige National Quality Award.
Legal Issues & Controversy
Purina sued Blue Buffalo in 2014, regarding their advertisements about their ingredients. Blue Buffalo claimed to have no by-products, but Purina’s lab testing said otherwise. Blue Buffalo counter-sued with the same claim, with both lawsuits eventually settling.
Purina was sued in 2015 after a consumer’s dog had gotten sick from their food. This was due to the additive propylene glycol, which has little to no information on its impact on canine health. After a second lawsuit in 2017 for false advertising, the company has not had any lawsuits since.
Established in 1946 as The Iams Company, it was created by Paul Iams when he realized there was a total lack of dog food available in most stores. By 1950, Paul Iams launched the first animal-based protein, which is the dry kibble we are all familiar with today.
Iams would change hands twice: once in 1999 to Proctor & Gamble, one of the largest corporations in the world, and a second in 2014 to Mars Inc., an American global manufacturer of various food and pet products.
Iams as a Company
Iams has been involved in various projects, including the Iams Home 4 the Holidays pet adoption drive in 1999. It has helped find permanent homes for pets in need, with over four million pets successfully adopted since its first drive.
In 2010, the Iams Home 4 the Holidays established a dog food drive for local shelters named the IH4TH Bags 4 Bowls program. It was a massive success, donating five million meals to shelters in dire need of food for their animals.
Legal Issues & Controversy
Iams was on the tail end of heavy criticism in 2002 from PETA, the animal welfare organization that has gone after hundreds of companies for animal-related issues. In 2003, due to the criticism coming from their questionable research practices, Iams severed ties with their main research source, Sinclair Research Center.
In 2019, consumers sued Iams over mislabeling their grain-free recipes, which had caused a number of dogs to become sick. It was tested and found to have significant amounts of grains and soy, which were marketed as not being in the food at all.

Purina Pro Plan vs. Iams ProActive Health Comparison
Purina Pro Plan and Iams ProActive Health are two widely popular dog foods that have some great features, while also having potential issues. Here is a breakdown of our comparison of variety, ingredients, and price:
Variety: Purina Pro Plan
Purina Pro Plan has a wide variety of recipes to choose from to fit the dietary requirements of most dogs. Iams Proactive Health also has a few selections, though their options are less extensive than Purina Pro Plan. Pro Plan and ProActive Health both have a puppy, adult, and senior options, but Purina Pro Plan has more flavor and protein sources for each stage of your dog’s life.
Ingredients: Purina Pro Plan
Both Purina Pro Plan and Iams ProActive Health contain wholesome ingredients, as well as potential allergens. Both Iams and Purina contain wheat, corn, and by-products, which are not ideal for some dogs’ dietary needs. However, due to their large selection, Purina tends to be more allergen-friendly than Iams.
Price: Iams ProActive Health
Iams ProActive Health and Purina Pro Plan are close in price and value, but Iams ProActive Health edges out Purina just enough to be the better value of the two. However, if you’re trying to save money, it’s not that big of a difference in price to really matter.
After comparing both dog food brands, we found the winner to be Purina Pro Plan. It has all the essential nutrients and protein your dog needs on a daily basis while being more allergen-friendly than Iams. If the price is a concern, Iams ProActive Health may be a better option for you. Otherwise, Purina Pro Plan is the clear winner here.
Hopefully, this comparison of Purina and Iams will help you decide. It’s important to make the best decision for your dog, so check all labels before feeding it to your dog. If you’re still unsure, ask your veterinarian for other options.
