Is Fresh Dog Food Healthier? What the Research Says
Why more dog owners are reconsidering processed food
For decades, dry kibble has been the default way many dogs are fed.
But as people have become more conscious of the role food plays in their own health, many have started asking the same question for their dogs:
Is fresh food actually healthier than highly processed dog food?
Interest in fresh feeding has grown rapidly over the last decade, driven by a desire for more natural ingredients, fewer highly processed foods, and greater transparency around what goes into a dog’s bowl.
While research into fresh feeding is still evolving, emerging studies and veterinary nutrition research are beginning to explore how ingredient quality, digestibility and processing methods influence canine health.
What do we mean by fresh dog food?
Fresh dog food typically refers to meals made from whole, minimally processed ingredients.
These meals often include:
• fresh meats
• organs
• vegetables
• natural sources of nutrients
Unlike dry kibble, fresh foods are usually lightly cooked or raw and stored refrigerated or frozen, rather than being processed into shelf-stable pellets.
This difference in processing plays an important role in how nutrients behave in the body.
Why processing matters
One of the biggest distinctions between fresh dog food and many conventional diets is how the food is processed.
Most dry kibble is produced through a method called extrusion, which involves:
• grinding ingredients into powders
• mixing with starches
• heating under high pressure
• expanding and drying the food into pellets
Because this process involves multiple high-temperature steps, some naturally occurring nutrients can be altered or reduced during production.
For this reason, many commercial foods rely on added vitamin and mineral premixes after processing to meet nutritional guidelines.
Fresh diets, by contrast, aim to obtain nutrients primarily from whole ingredients themselves.

Digestibility and nutrient absorption
Digestibility describes how easily the body can break down food and absorb nutrients.
Higher digestibility means that more nutrients are available to the dog rather than passing through the digestive tract unused.
Research comparing lightly cooked fresh diets and extruded kibble has found that fresh diets can show higher digestibility and changes in the gut microbiome composition of dogs.
Greater digestibility can influence several aspects of health, including:
• nutrient absorption
• stool quality
• digestive comfort
Fresh foods and the canine gut microbiome
Inside every dog’s digestive system lives a complex ecosystem of microorganisms known as the gut microbiome.
These microbes help with:
• digesting food
• producing beneficial compounds
• regulating immune responses
Diet is one of the most powerful influences on this ecosystem.
Whole foods rich in natural fibres and nutrients can help support beneficial gut bacteria, while heavily processed diets may influence microbial diversity in different ways.
You can read more about this in our article on the dog gut microbiome.
Ingredient transparency and whole foods
Another reason fresh feeding appeals to many owners is ingredient clarity.
Fresh meals are typically made from ingredients you can recognise:
• beef
• chicken
• carrots
• pumpkin
• leafy greens
In contrast, many dry foods rely on rendered meals, starch concentrates and processed ingredient blends.
Both approaches can meet nutritional standards, but whole foods provide nutrients in a form that many owners find easier to understand and trust.
Variety and nutritional diversity
In nature, animals rarely eat exactly the same food every day.
Fresh feeding often incorporates rotational variety, meaning recipes change over time to include different ingredients.
This variety may help support broader nutrient diversity and can also contribute to a more varied gut microbiome.
Rather than relying on a single formulation, rotational feeding encourages a range of whole food nutrients over time.
What the research currently shows
Scientific research into fresh feeding is still developing, but several studies have explored how different diets affect digestion and the microbiome in dogs.
Research has shown that:
• fresh diets may improve nutrient digestibility compared with some extruded diets
• diet processing can significantly influence gut microbial composition
• ingredient composition affects metabolic byproducts produced during digestion
While more long-term studies are needed, these findings highlight how processing methods and ingredient quality both play important roles in canine nutrition.
Choosing the right diet for your dog
There is no single feeding approach that suits every dog.
Some dogs do well on traditional commercial diets, while others thrive on fresh foods that prioritise whole ingredients and minimal processing.
Understanding how food is made — and how different ingredients behave in the body — can help dog owners make more informed feeding decisions.
For many families, fresh feeding offers a way to provide meals built from recognisable ingredients with thoughtful preparation.
The Embark approach
At Embark Raw Pantry, our meals are built around two core principles.
Rotational nutritional diversity
Recipes rotate whole ingredients each week to help support balanced nutrition over time.
Gentle preparation
Vegetables are lightly cooked to help break down plant fibres, improving digestibility while still nourishing the gut microbiome.
Our goal is to create meals that are both nutritionally considered and grounded in real food ingredients.
