🥕 Nutritional Value Comparison: Iams vs Purina Pro Plan

Are you choosing your pet’s foods based on quantity or quality? Do the products of your brand choice meet your pet’s standard nutritional requirement?

In feeding our dogs and cats, we should be more concerned with quality much more than quantity. The quality of our pet’s foods is expressed by the nutritional content of the food.

To get a better understanding of what the nutrients of your favorite brand offers, do a proper examination of the product label.

The label contains the different types of nutrients and their amount as well as the feeding amounts and schedules specific to different age, size and breed of dogs and cats respectively.

Protein, fat, fiber and moisture are vital and compulsory nutritional requirement for every pet food. The amounts of these nutrients vary depending on the brand and product, so let’s see what Purina Pro Plan and Iams guarantee.

Purina Pro Plan Protein(dry) Protein(wet) Fat (dry) Fat(wet) Fiber (dry) Fiber (wet)
Dog 31.8% 47.3% 17.9% 16.4% 4.3% 7.2%
Cat 45.6% 51.5% 17.4% 17.1% 3.6% 6.9%

Proteins are made up of amino acids. Some of these amino acids cannot be synthesized by our dogs and cats, therefore, they must be gotten from the protein-based foods they consume.

Some of our pet may have physiological conditions which may require specific nutritional content in various amounts.

For example, some of our furry friends may require more protein than others, especially during, gestation and lactation which require more protein intake than routine exercises.

Carnivores tend to avoid food  types that are deficient in essential amino acids so much that they would rather give in to a vegan diet that contains enough protein and vitamin D supplements.

About 30-35% of the protein dogs and cats consume are used to maintain skin and coat health.

The growth of kittens and puppies, waste elimination and hemoglobin synthesis in dogs and cats will be hampered if they are feed with protein deficient meals.

Be it plant or animal-based protein, Purina Pro Plan and Iams use high quality protein in varying amounts as required by their different recipe formulations.

As far as protein content goes, Purina Pro Plan is seen to dominate on both cat and dog foods.

Fat Content

Fatty acids are the main constituent of fats. Like amino acids in protein, some essential fatty acids cannot be synthesized by the carnivores, thus, they are readily available in the fat-based foods consumed by our dogs and cats.

Fats are considered unhealthy by some experts but for dogs and cats, it is a major source of energy.

In fact, the energy provided by fats alone is more than twice the energy gotten from protein and carbohydrate combined. 

Nutritionally, fats provide the necessary environment for absorption of fat-soluble vitamins in the gut of companion animals.

They also play a role in the maintenance of a healthy skin and coat of our dogs and cats, help in building a strong immune system and reproductive function, ensures proper cell functioning and structuring, and, aids in the retention of water in the body of our pets.

Not only does fats play important roles in the nutrition of cats and dogs, it also improves the taste and texture of our pet foods products.

Purina Pro Plan and Iams are two great brands with excellent amounts of protein, however, Purina Pro Plan dry and wet dog food guarantees more fats than Iams whereas Iams cat foods offer more fat than Purina Pro Plan.

Fibre Content

Like every other companion animal, dogs and cats need varying amounts of fibre at different stages of life for effective gut transit.

The basic function and benefit of fibre in dogs and cats’ diet is to increase bulk and water in their intestinal contents, maintain adequate levels of good bacteria and enhance gut health.

As fibres are not essential nutrients for cats and dogs, they cannot develop a deficiency.

However, the presence of fiber above prescribed quantities in our pets’ body system could lead to weight loss but at the same time aid in regulating hyperglycemia, diabetes mellitus, diarrhoea and constipation as well as improve gastrointestinal functioning.

Dog foods with high amount of starch, such as rice, have less fiber content while wheat bran products are relatively high in fiber.

The fiber content of our pets’ foods could be lower or higher depending on the vet’s prescription so it’s important to consult them at all time for your pet’s nutrition.  

There is a slight difference in the fiber content of both brands as Purina Pro Plan food dominates across all food types especially in wet cat foods where it guarantees about 8.0% more fibre than what Iams offers.

💰 Price Comparison

Pet owners on a budget could easily get exhausted when it comes to picking the food that is just right for their furry companions.

The price of cat and dog food is one thing we all think about and take into consideration when planning our pet care system.

With so many brand options and pet food vendors populating the food market, tracking down the prices of your pet’s food becomes tricky and confusing.

However, devoting some quality time to gather good information (as provided in this article) and restructuring the budget of your pet care because of the food and treat of choice will not be such a bad idea as we want the best for cats and dogs.
