Buying Guide 

Purina One History

For over 120 years, Purina has been a household name for pet food. Originally founded in 1894 by three men with no experience whatsoever selling animal feed and named Robinson-Danforth Commission Company after themselves.

The pet food brand was renamed Ralston Purina just five short years later when they realized that there were very few retail outlets where people would buy their product due to it being designed specifically for farm animals (which didn’t exist anymore). 

They evolved into one of America’s most beloved dog food companies, thanks mainly in part because they’re constantly innovating new recipes like Pro Plan Savor Dog Food which are made from quality ingredients so your pup can enjoy life longer than ever before!

In 1987, Purina released a fourteen-year study that proved that feeding your dog appropriate foods throughout life stages can have significant impacts on their health and longevity. 

It also showed how the diet you feed them might be impacting their allergies! In 1988 they launched what is now considered one of the world’s first-ever hypoallergenic food-fed only ingredients isolated from themselves to reduce all allergic reactions among dogs.

In 2001, Nestle acquired Purina. The company then became a globally recognized name in pet care and other markets such as treats, dental chews, probiotics, and more!

IAMS History

Paul IAMS started the company in 1946 when he was just 16 years old. His first product, 999 dog food, came out shortly after and would go on to become a household name for animal protein-rich dry kibble that is still sold today. 

In 1984, IAMS launched their life stage formulas designed with specific needs of dogs at different stages like growing puppies or seniors experiencing joint discomfort as they age. 

Their natural line also emerged during this period, where carbohydrates replaced highly processed grains, and soy proteins became more prevalent than meat-based ones.

Procter and Gamble purchased IAMS in 1999. When P&G bought IAMS Co., they announced their intentions of expanding the pet food brand globally. Later in the 2000s, Premium Protection dog food line came to market- a specially formulated food for puppies that is rich with Omega 3 & 6 fatty acids as well as antioxidants like vitamin A, E, and C.

In a surprising move, the MARS company announced that they had purchased P&G’s IAMS for an undisclosed amount. 

The acquisition will be finalized by transferring $3 billion in assets and intellectual properties from P&G to Mars’ petcare division. With shares soaring on Wall Street following the announcement, it is clear this was something investors were hoping would happen sooner than later.

Since acquiring Pedigree back in 2016, it seemed inevitable that Mars would purchase one of their key competitors – particularly given how large they are as dog food producers worldwide (they’re responsible for more than half).

Difference Between Purina And IAMS


A guaranteed analysis shows that IAMS will be cheaper than Purina.

Purina’s most basic kibble (Purina Dog Chow) costs roughly as much as IAMS’s basic kibble, but past that, almost all of Purina’s options are pricier.


IAMS and Purina are both significant players in the world of pet food, but what sets them apart? For starters, IAMS has a higher-end range with more real meat. 

This means that most dogs will prefer it to their basic recipes as they like ingredients from animals better than artificial flavors. However, Purina’s version is cheaper, so if you want your dog to eat well, then you should consider this brand of dog food. 

Nutritional Value

When it comes to nutritional content, both Purina and IAMS kibbles are almost identical. The difference lies in the quality of ingredients that go into each food type. Whole foods from IAMS may be suitable for your budget or have lower calories than some higher-end brands on the market. 

There is no comparison when you compare their best with Purina top-shelf offerings like dog chow supreme – which by all means should not even be considered a cheap brand!

Where Can I Find It?

Purina and IAMS are both available at major pet stores, but Purina is also sold in some grocery stores.

Recall Of Purina

Purina is a company that has had its share of recalls, and in 2013 they were not immune to the dangers. The Purina dog food was recalled over Salmonella contamination, but luckily it was limited to one bag. 

In 2016 Purina had a recall history. It also issued a recall for wet cat food because there may have been discrepancies with what nutrients are present on the label versus how much is inside each can.

In 2003 when two people died after eating contaminated pet foods (both from products made by Menu Foods), many companies saw their sales plummet as consumers became wary about buying any product related to animals whatsoever due to fears that no matter where you purchased your pets’ staples.

Recall Of IAMS

IAMS has had two recalls in the past decade, one for mold and another because of Salmonella. The first took place in 2011 when there was a voluntary recall over concerns that their dry food’s levels of Aflatoxin exceeded acceptable limits; this is considered to be Mold under English law. 

The next happened more recently–in 2013–when the FDA issued a mandatory recall on several IAMS recipes due to fears about Salmonella contamination.

Purina Vs IAMS? Sneak Peek At The Winner

Purina dog food is a great choice for dog owners because they have such an extensive selection of food to choose from. They are one of those pet food brands that make their products available in most places, so it’s easier than ever before to find them no matter where you live or what time of day it may be. 

In the marketplace of today’s world, it is not enough to provide excellent products and services with great nutritional value. 

One must also be conscious about how one impacts their community to stand out from others who are doing nothing but just making money by providing mediocre goods or services.


Purina is a more expensive option, but it’s worth the investment. They have higher quality ingredients with excellent nutritional value and are easier to find in pet stores than IAMS. If you don’t want to spend as much money on your dog’s food, however, then IAMS may be better for you. 

There are some drawbacks to this brand of wet and dry kibble that we hope you consider before making your final decision; one issue is their limited ingredient selection which can make feeding time difficult if there isn’t an easy substitute ingredient available at local grocery stores or specialty pet shops.

Purina offers a range of products that are affordable yet still give your pet the nutrition he needs. As long as you find one from their line-up that fits within your budget and meets what’s on your list of requirements for an ideal product.
