Why Do People Switch from Kibble to Raw? The Truth About Ultra-Processed Dog Food

Raw dog food is fast becoming the choice of savvy pet owners across the UK. If you’ve ever stood in the pet food aisle, staring at a wall of colourful kibble bags and wondering, “Is this really the best I can do for my dog?” you’re not alone.

Across the UK, a quiet revolution is taking place. More and more dog owners are turning away from traditional kibble and embracing fresh, natural feeding. But what’s actually driving this shift? In this episode of The Raw Feeding Journal, host Charlotte sits down with industry expert Robin to answer one of the most frequently asked questions in the raw feeding world: Why do people switch from kibble to raw?

The answer, it turns out, is refreshingly simple. It comes down to eliminating artificial fillers, preservatives, high carbohydrates, and ultra-processed ingredients that can quietly contribute to chronic inflammation in dogs.

The Problem with Ultra-Processing

We often forget that kibble is one of the most processed foods a dog can eat. Through a high-heat manufacturing process called extrusion, natural nutrients are stripped away, only to be replaced with synthetic vitamins, artificial preservatives, and flavour enhancers. Robin compares it to the difference between a nourishing home-cooked meal and a shelf-stable ready meal and once you hear it framed that way, it’s hard to unsee.

The Hidden Carbohydrate Trap

Here’s something that surprises many owners: some kibbles contain up to 60% carbohydrates. Yet dogs have no biological requirement for carbs at all. In this episode, Robin explains how these excess starches can spike blood sugar, encourage weight gain, and feed harmful gut bacteria—all of which can fuel the chronic, low-grade inflammation linked to allergies, itchy skin, digestive troubles, and joint issues.

Inflammation: The Silent Culprit

Perhaps the most compelling reason owners make the switch is to tackle inflammation at its source. By removing ultra-processed ingredients and returning to a fresh, species-appropriate diet, many owners report dramatic improvements:

• Glossier coats
• Healthier skin
• Fresher breath
• Smaller stools
• Cleaner teeth
• More balanced energy levels

Real Food for Real Results

This episode isn’t about fear-mongering it’s about empowerment. Charlotte and Robin offer practical, reassuring advice for anyone considering the switch, including the importance of choosing DEFRA-registered suppliers and consulting a knowledgeable vet or canine nutritionist.

Whether you’re a curious kibble-feeder or already dipping your toes into raw, this episode will give you the clarity and confidence to make an informed choice for your dog’s long-term health.

SPEAKER_01 0:00

Hello and welcome back to the Raw Feeding Journal. I'm Charlotte.

SPEAKER_00 0:04

And I'm Robin. Today we're answering a question that so many dog owners ask when they first hear about raw feeding. Why do people switch from kibble to raw in the first place?

SPEAKER_01 0:15

It's such a common question, Robin. For decades, kibble has been the default choice for most UK households. It's convenient, it's affordable, and it's what most of us grew up feeding our dogs. So what's driving this shift?

SPEAKER_00 0:30

Great question. At its core, the number one reason people make the switch is to eliminate artificial fillers, preservatives, high carbohydrates, and ultra-processed ingredients, all of which can contribute to chronic inflammation in dogs.

SPEAKER_01 0:45

Let's unpack that. When people say kibble is ultra-processed, what do they actually mean?

SPEAKER_00 0:51

Well, think about how kibble is made. Raw ingredients are ground down, mixed with starches, and then cooked at extremely high temperatures through a process called extrusion. This high heat destroys many of the natural nutrients and enzymes. To make it shelf stable and palatable, manufacturers then add synthetic vitamins, artificial preservatives, colours, and flavour enhancers.

SPEAKER_01 1:15

So it's a bit like comparing a home-cooked meal to a heavily processed ready meal.

SPEAKER_00 1:20

That's a perfect analogy, Charlotte. And just like with human food, those ultra-processed ingredients can take a toll over time.

SPEAKER_01 1:27

You mentioned carbohydrates. Why are high carbs a concern in kibble?

SPEAKER_00 1:32

This is a big one. To hold that little biscuit shape together, kibble needs starch, often from grains, potatoes, or peas. Some kibbles can contain anywhere from 40 to 60% carbohydrates. But here's the thing. Dogs have no biological requirement for carbohydrates. Their bodies are designed to thrive on protein and fat.

SPEAKER_01 1:57

And what happens when they're eating all those excess carbs?

SPEAKER_00 2:00

Excess carbohydrates can cause blood sugar spikes and crashes, contribute to weight gain, and feed the harmful bacteria and yeast in the gut. Over time, this can lead to chronic, low-grade inflammation, which is linked to all sorts of issues, from itchy skin and ear infections to joint problems.

SPEAKER_01 2:18

That word inflammation keeps coming up. Why is it such a concern for dog owners?

SPEAKER_00 2:24

Because chronic inflammation is often the silent root cause behind so many health problems we see in dogs today. It's connected to allergies, digestive issues, and even more serious long-term conditions. When people remove those inflammatory, ultra-processed ingredients and switch to fresh, whole foods, they often see these issues improve dramatically.

SPEAKER_01 2:48

So it's really about going back to basics, feeding a dog what it's biologically designed to eat.

SPEAKER_00 2:55

Exactly. Raw feeding focuses on fresh muscle meat, organ meat, raw bones, and healthy fats. No artificial fillers, no synthetic preservatives, no unnecessary carbohydrates, just real, species-appropriate food.

SPEAKER_01 3:10

And what changes do owners typically notice after making the switch?

SPEAKER_00 3:14

The transformations can be remarkable. Owners frequently report shinier coats, healthier skin, better digestion, smaller and firmer stools, fresher breath, cleaner teeth, and more stable energy levels. Many also notice their dogs seem calmer and happier overall.

SPEAKER_01 3:33

That's incredible. But Robin, for someone feeling nervous about switching, what would you say to them?

SPEAKER_00 3:40

I'd say do your research and start with reputable DEFRA-registered suppliers who follow strict safety standards. And if you're unsure, consult a vet or canine nutritionist who understands raw feeding. It doesn't have to be complicated. There are plenty of complete balanced raw options available that make the transition simple.

SPEAKER_01 4:00

Brilliant advice. So, to sum up, people switch from kibble to raw to eliminate ultra-processed ingredients, cut out unnecessary carbs and additives, and reduce chronic inflammation, giving their dogs a fresher, more natural diet.

SPEAKER_00 4:18

Exactly, Charlotte. It's all about supporting your dog's long term health and vitality from the inside out.
