Both are excellent pet food brands with a long history of excellence in their formulations. But if you need help deciding which one is best for your pet, I’m here to help.

About the Eukanuba brand

The Eukanuba brand was established in 1969 by Paul Iams, the same person behind the Iams brand. Nowadays, both these brands are owned by Mars, Incorporated.

Moreover, Eukanuba focuses on pet food products with athletic formulations. While they have several selections for cats, most of their product line is composed of dog food options.

Eukanuba is one of the most popular pet food brands in the market. Thousands of pet owners trust their formulations of both wet and dry food.

Overall, Eukanuba produces ‘science-based’ dog food products for active breeds. They have formulations from puppy to senior age.

About the Iams brand

Iams was founded in 1946, roughly two decades earlier than Eukanuba. Paul Iams, the same founder of Eukanuba, conceived the Iams brand to produce quality pet food products.

Moreover, Paul Iams trailblazed the pet food industry by being the first one to consider cats and dogs as carnivores. From there, the entire pet food industry took its cue.

As mentioned earlier, Iams is under the ownership of Mars, Incorporated. It joins the company’s roster of pet food brands, including Nutro, Pedigree, Royal Canin, and Evo, to name a few.

Overall, Iams is a highly recognizable pet food brand. They have selections for both cats and dogs, which is specific to the pets’ needs.

Eukanuba vs Iams comparison

1.    Available food formulations

In terms of product selection, both brands have something to offer. However, it’s undeniable that Iams has a significant advantage when it comes to variety.

First of all, I noticed that Eukanuba’s selections are focused on dogs. Meanwhile, Iams has an array of formulations for both cats and dogs.

Aside from that, Iams has food formulas based on the pet’s age and needs. For example, for cat food, they have specific food products to alleviate hairball, urinary tract problems, and so on.

Meanwhile, Eukanuba’s food options primarily focus on canine athletic health. It has high protein and is made to fuel up active dogs.

Nevertheless, both brands have options for all life stages. The right choice depends on what your dog or cat needs.

I recommend consulting a veterinarian if your pet has a lingering health condition or special dietary needs. This is to ensure that your dog or cat is getting the nutrition it needs to stay healthy.

2.    Ingredients

Ingredients are often the deal-breaker regarding the right choice of a pet food product. Eukanuba is generally known for quality ingredients, while Iams has a reputation for its natural ingredients.

Let me compare two products from these brands to give you a clearer view. I will discuss the Iams Large Breed Dry Dog Food and the Eukanuba Large Breed Dry Dog Food.

Both these products cater to the same breed size and life stage. However, they have significant similarities in terms of ingredients.

First, both these products are available in lamb and chicken formulas. They also have real meat as the first ingredient.

Aside from that, they have meat by-products in the mix. This is aside from the large portion of grains in the list.

The difference is that Iams use whole grains in their formulations. This is an added benefit, though it may still be an issue for pets with sensitivities to all grains.

In my opinion, Iams and Eukanuba have little difference in their ingredients. Even the nutritional analysis of these two products is extremely similar (more on below).

3.    Nutritional analysis

Both Iams and Eukanuba have high-protein nutrition to match growing and active pets.

Most of their dry dog food has protein levels ranging from 20% to 29%. Meanwhile, canned food from these brands also has similar protein content at around 40% to 41%.

Nevertheless, Iams tend to be a tad lower in fat content. Still, the difference is only very significant if you have a pet who is very sensitive to this component.

When it comes to digestive factors, most Eukanuba food products have higher fiber content than those of Iams. So if you’re looking for pet food that will firm up your pet’s stool, Eukanuba would be a great option.

4.    Safety recalls and product safety.

Safety recalls are common practice not just in pet food but in every industry that involves the production of goods. So just because a pet food brand has a recall history doesn’t mean they are no longer safe to feed your dog.

Both Iams and Eukanuba have issued recalls before. These are either exclusive to the brand or a major recall that involves multiple pet food names.

Below, I listed a quick rundown of the latest recalls between the two brands: 


  • August 2013. This recall involved large batches of puppy and adult dog food products. It’s recalled for potential salmonella contamination.
  • July 2010. Another case of potential salmonella risk led to a recall of three dry dog food batches.
  • March 2007. Due to melamine contamination, an FDA report caused the recall of Eukanuba canned and wet pouch food products.


  • August 2013. As part of a massive recall in the pet food industry, Iams also pulled out multiple varieties of dog food products from the market.
  • March 2013. Due to the potential for mold, a recall was done in March 2013 involving the Iams Shakeables.
  • December 2011. The Iams ProActive Health Puppy Dry Dog Food was recalled due to aflatoxin.
  • August 2010. Due to a potential risk for salmonella, the Iams Indoor Weight Control with Hairball Care Cat Food was recalled.
  • July 2010. Batches of the Iams Veterinary Formulas Dry Cat Food were recalled due to a potential risk for salmonella.
  • June 2010. Batches of the Iams ProActive Health Canned Cat and Kitten Food were recalled due to low thiamine levels.
  • March 2007. Like Eukanuba, batches of Iams pet food were recalled due to melamine contamination.

5.    Price range

Regarding the price range, Iams is the more affordable of the two. For example, the 30-lb. dry dog food bags from Iams is about 40% cheaper than what Eukanuba offers.

This makes Iams a very attractive option for pet owners on a budget. And despite the lower price, Iams still produces quality formulations.

Nevertheless, there’s a very good reason behind Eukanuba’s higher pricing. This brand focuses on specialized diets, so it’s expected to cost more than maintenance formulations typically offered by Iams.

In the end, pricing should be the least criterion to consider when buying a pet food product. The quality of ingredients and nutrition should always come first.

Which one is the best pet food brand?

If you’re looking for affordable yet decent nutrition for your pets, Iams will not disappoint. They also have a wide variety for both cats and dogs that Eukanuba doesn’t have.

Meanwhile, if you want more precise nutrition for your active breed, you should consider Eukanuba. The only trade-off here is the higher price tag.

Both are great pet food brands. The choice all boils down to what your pet needs and what you prefer in terms of price, ingredients, and nutritional value.
