5 Myths About Dry Dog Food: Told by Fresh Dog Food Companies

Dry dog food, often referred to as kibble, has been a staple in pet households for decades. However, with the rise of raw and cooked fresh dog food diets, many companies in these sectors have positioned kibble as an inferior choice. While all diets have their pros and cons, misinformation can lead pet owners to make decisions based on myths rather than facts.

In this article, we’ll debunk five common myths about dry dog food that are frequently circulated by some fresh dog food companies and their marketing teams.

Myth #1: "Dry Dog Food Is Full of Harmful Fillers and Low-Quality Ingredients"

One of the most common claims is that kibble is packed with "fillers" like corn, wheat, and soy, which are said to be nutritionally empty and even harmful to dogs. While it’s true that some lower-quality kibble brands may include these ingredients in excessive amounts, high-quality dry dog foods are formulated based on scientific research to provide complete and balanced nutrition.

The Truth:

• "Fillers" is a misleading term. Ingredients like corn and wheat contain essential nutrients such as amino acids, fiber, and vitamins. The term filler itself means something with no nutritional value at all.

• A study published in the Journal of Animal Science (2017) found that dogs digest grains efficiently and can utilise their nutrients effectively.

• Many premium kibble brands use high-quality protein sources, whole grains, and healthy fats, providing a balanced diet for dogs.

Myth #2: "Dry Dog Food Causes Dehydration and Kidney Problems"

Another common myth is that feeding kibble leads to chronic dehydration, straining a dog’s kidneys and causing long-term damage. This claim is often used to advocate for raw or cooked diets, which naturally contain higher moisture content.

The Truth:

• Dogs on a kibble diet will drink more water to compensate for the lower moisture content, and studies show they can maintain proper hydration levels as long as fresh water is provided.

• The National Research Council (NRC) guidelines confirm that dogs regulate their water intake based on their diet.

• There is no credible scientific evidence linking kibble to kidney disease in healthy dogs. However, dogs with pre-existing kidney conditions may benefit from wet or prescription renal diets designed for their needs.

Myth #3: "Kibble Is Highly Processed and Lacks Nutrients"

Some fresh dog food marketing teams often argue that dry food is heavily processed, leading to nutrient loss and lower bioavailability in order to promote their products.

The Truth:

• While kibble is processed through extrusion or baking, this does not inherently make it unhealthy.

• Many high-quality kibble brands incorporate advanced cooking techniques that retain essential nutrients and sometimes add cold-pressed oils and post-cooking vitamin fortifications.

• Studies, such as one published in Veterinary Sciences (2021), indicate that kibble diets can provide adequate and balanced nutrition when properly formulated.

Myth #4: "Dogs Can’t Digest Kibble Properly Because It Contains Carbohydrates"

A widespread claim in fresh feeding communities is that dogs should eat a diet solely based on meat because their ancestors were carnivores, and that carbohydrates in kibble cause digestive issues or obesity.

The Truth:

• Dogs are not obligate carnivores like cats; they are facultative carnivores, meaning they can digest and utilise carbohydrates for energy.

• A study from the Nature journal (2013) identified genetic adaptations in dogs that enable them to digest starches more efficiently than wolves.

• Whole grains in some kibble can provide fiber for digestive health, help maintain healthy blood sugar levels, and aid in weight management.

Myth #5: "Dry Dog Food Is Full of Harmful Preservatives and Additives"

Many raw and cooked dog food brands claim that kibble is laden with synthetic chemicals, artificial preservatives, and harmful additives that can negatively impact a dog’s health.

The Truth:

• High-quality kibble brands use natural preservatives like mixed tocopherols (a form of vitamin E) and rosemary extract, which are safe and effective.

• Artificial preservatives such as BHA and BHT have been a concern, but reputable pet food manufacturers have largely phased them out in favor of natural alternatives.

• The FDA regulates pet food ingredients, ensuring their safety, and extensive research has not confirmed any direct health risks from properly formulated dry dog food.

Conclusion: Choosing the Right Diet for Your Dog

While raw and cooked dog food diets can offer benefits, it’s important to separate fact from fiction when evaluating kibble. Dry dog food can be a convenient, nutritionally complete, and balanced option when sourced from a reputable brand. Every dog is unique, and the best diet depends on individual health needs, lifestyle, and owner preference.

Before making any dietary changes, consult with a qualified canine nutritionist or veterinarian to ensure you’re making the best choice for your dog’s well-being.
